From Neuroscientist to TV Host & Producer for Steve Harvey: Meet Anna-Kay
"In many ways, girls like me are not "meant" to make it in Hollywood -- at least on paper. I am from a single-parent, low-income home, I'm a black woman, and I'm the daughter of immigrants."
"I'm Anna-Kay Thomas (everyone calls me AK!) and I'm 28 from West Palm Beach, Florida. I'm a TV Host and Producer in sunny Los Angeles, CA. You can catch me on IG @annakaythomas"
"I took a major leap of faith and moved to New York after college to pursue hosting. After years of working to break into the industry, I won a 2014 national VH1 competition to be a reporter alongside Nick Lachey, which kickstarted my career. Since then, I've worked for companies like NBC, The Hollywood Reporter, Billboard and Condé Nast. Most recently, I moved across the country to L.A. to work as a host/producer for Steve Harvey!"
"In many ways, girls like me are not "meant" to make it in Hollywood -- at least on paper. I am from a single-parent, low-income home, I'm a black woman, and I'm the daughter of immigrants. When I started, I had no Hollywood connections and I had no industry experience. Growing up was really hard at times but I was able to change my trajectory by focusing on education."
"I attended Magnet Arts middle and high schools and then worked my way to Dartmouth College, where I graduated with a B.A. in Neuroscience. Even though I took a major leap of faith and jumped to entertainment after college, working hard in school along with my humble upbringing by a single Jamaican mom taught me hustle by example. It's why I have the grit and tenacity for a field as tough as entertainment."
"Work hard and play nice. Entertainment is a multi-billion dollar global industry but it's a smaller professional space than you would think and everyone really does know everyone! Talent isn't enough these days. No one wants to work with, or be friends with, a jerk. Try to think of the good in life and what you are truly grateful for so that you can genuinely find a way to be nice to everyone. You never know who may be in a position to help you out later in your career!"

How NBC's 'This Is Us' Staff Writer Went from 'Ballet Dreams' to Creating for the Masses


have a different sort of life, many of 'em," said Dinah; "they work at different things--some in the mill, and many in the mines, in the villages round about. But the heart of man is the same everywhere, and there are the children of this world and the children of light there as well as elsewhere. But we've many more Methodists there than in this country."
you know--I should like you to wash your face and have a clean cap on. Do you remember what David did, when God took away his child from him? While the child was yet alive he fasted and prayed to God to spare it, and he would neither eat nor drink, but lay on the ground all night, beseeching God for the child. But when he knew it was dead, he rose up from the ground and washed and anointed himself, and changed his clothes, and ate and drank; and when they asked him how it was that he seemed to have left off grieving now the child was dead, he said, 'While the child was yet alive, I fasted and wept; for I said, Who can tell whether God will be gracious to me, that the child may live? But now he is dead, wherefore should I fast? Can I bring him back again? I shall go to him, but he shall not return to me.'"
"Eh, that's a true word," said Lisbeth. "Yea, my old man wonna come back to me, but I shall go to him--the sooner the better. Well, ye may do as ye like wi' me: there's a clean cap i' that drawer, an' I'll go i' the back kitchen an' wash my face. An' Seth, thee may'st reach down Adam's new Bible wi' th' picters in, an' she shall read us a chapter. Eh, I like them words--'I shall go to him, but he wonna come back to me.'"
And so there was earnest prayer--there was faith, love, and hope pouring forth that evening in the little kitchen. And poor, aged, fretful Lisbeth, without grasping any distinct idea, without going through any course of religious emotions, felt a vague sense of goodness and love, and of something right lying underneath and beyond all this sorrowing life. She couldn't understand the sorrow; but, for these moments, under the subduing influence of Dinah's spirit, she felt that she must be patient and still.

Here we present a protocol for the fabrication of inkjet-printed multilayer sensor structures on additively manufactured substrates and foil.
A method to combine additively manufactured substrates or foils and multilayer inkjet printing for the fabrication of sensor devices is presented. First, three substrates (acrylate, ceramics, and copper) are prepared. To determine the resulting material properties of these substrates, profilometer, contact angle, scanning electron microscope (SEM), and focused ion beam (FIB) measurements are done. The achievable printing resolution and suitable drop volume for each substrate are, then, found through the drop size tests. Then, layers of insulating and conductive ink are inkjet printed alternately to fabricate the target sensor structures. After each printing step, the respective layers are individually treated by photonic curing. The parameters used for the curing of each layer are adapted depending on the printed ink, as well as on the surface properties of the respective substrate. To confirm the resulting conductivity and to determine the quality of the printed surface, four-point probe and profilometer measurements are done. Finally, a measurement set-up and results achieved by such an all-printed sensor system are shown to demonstrate the achievable quality.
Additive manufacturing (AM) is standardized as a process where materials are joined to make objects from 3D model data. This is usually done layer upon layer and, thus, contrasts with subtractive manufacturing technologies, such as semiconductor fabrication. Synonyms include 3D-printing, additive fabrication, additive process, additive techniques, additive layer manufacturing, layer manufacturing, and freeform fabrication. These synonyms are reproduced from the standardization by the American Society of Testing and Materials (ASTM)1 to provide a unique definition. In the literature, 3D-printing is referred to as the process where thickness of the printed objects is in the range of centimeters to even meters2.
More common processes, such as stereolithography3, enable the printing of polymers, but the 3D-printing of metal is also already commercially available. The AM of metals is employed in manifold areas, such as for the automotive, aerospace4, and medical5 sectors. An advantage for aerospace structures is the possibility to print lighter devices through simple structural changes (e.g., by using a honeycomb design). Consequently, materials with, for instance, greater mechanical strength, that would otherwise add a significant amount of weight (e.g., titanium instead of aluminum)6, can be employed.
While the 3D-printing of polymers is already well established, metal 3D-printing is still a vibrant research topic, and a variety of processes have been developed for the 3D-printing of metal structures. Basically, the available methods can be combined into four groups7,8, namely 1) using a laser or electron beam for cladding in a wire-fed process, 2) sintering systems using a laser or electron beam, 3) selectively melting powder using a laser or electron beam (powder bed fusion), and 4) a binder jetting process where, commonly, an inkjet print head moves over a powder substrate and dispenses binding agent.
Depending on the process, the respective manufactured samples will exhibit different surface and structural properties7. These different properties will have to be considered in further efforts to further functionalize the printed parts (e.g., by fabricating sensors on their surfaces).
In contrast to 3D-printing, the printing processes to achieve such a functionalization (e.g., screen and inkjet printing) cover only limited object heights from less than 100 nm9 up to a few micrometers and are, thus, often also referred to as 2.5D-printing. Alternatively, laser-based solutions for high-resolution patterning have also been proposed10,11. A comprehensive review of the printing processes, the thermally dependent melt temperature of nanoparticles, and the applications is given by Ko12.
Although screen printing is well established in the literature13,14, inkjet printing provides an improved upscaling ability, together with an increased resolution for the printing of smaller feature sizes. Besides that, it is a digital, noncontact printing method enabling the flexible deposition of functional materials on three-dimensional. Consequently, our work is focused on inkjet printing.
Inkjet printing technology has already been employed in the fabrication of metal (silver, gold, platinum, etc.) sensing electrodes. Application areas include temperature measurement15,16, pressure and strain sensing17,18,19, and biosensing20,21, as well as gas or vapor analysis22,23,24. The curing of such printed structures with limited height extension can be done using various techniques, based on thermal25, microwave26, electrical27, laser28, and photonic29 principles.
Photonic curing for inkjet-printed structures allows researchers to use high-energy, curable, conductive inks on substrates with a low-temperature resistance. Exploiting this circumstance, the combination of 2.5D- and 3D-printing processes can be employed to fabricate highly flexible prototypes in the area of smart packaging30,31,32 and smart sensing.
The conductivity of 3D-printed metal substrates is of interest to the aerospace sector, as well as for the medical sector. It does not just improve the mechanical stability of certain parts but is beneficial in near-field as well as capacitive sensing. A 3D-printed metal housing provides additional shielding/guarding of the sensor's front-end since it can be electrically connected.
The aim is to fabricate devices using AM technology. These devices should provide a sufficiently high resolution in the measurement they are employed for (often at micro- or nanoscale) and, at the same time, they should fulfill high standards regarding reliability and quality.
It has been shown that AM technology presents the user with enough flexibility to fabricate optimized designs33,34 which improve the overall measurement quality that can be achieved. Additionally, the combination of polymers and single-layer inkjet printing has been presented in previous research35,36,37,38.
In this work, available studies are extended, and a review about the physical properties of AM substrates, with a focus on metals,and their compatibility with multilayer inkjet printing and photonic curing is provided. An exemplary multilayer coil design is provided in Supplementary Figure 1. The results are used for providing strategies for the inkjet printing of multilayer sensor structures on AM metal substrates.
CAUTION: Before using the considered inks and adhesives, please consult the relevant Material Safety Data Sheets (MSDS). The employed nanoparticle ink and adhesives may be toxic or carcinogenic, dependent on the filler. Please use all appropriate safety practices when performing inkjet printing or the preparation of samples and make sure to wear appropriate personal protective equipment (safety glasses, gloves, lab coat, full-length pants, closed-toe shoes).
NOTE: The protocol can be paused after any step except steps 6.3 - 6.6 and steps 9.2 - 9.5.
1. Preparation of 3D-printed Substrates
Prepare computer-aided design (CAD) drawings, ideally using the stereolithography .stl file format.
NOTE: The used designs are illustrated in Supplementary Figure 2 and Supplementary Figure 3.
Choose the AM process based on the material properties required by the target application (see Table 1 for the respective process limitations).
NOTE: In this work, we used samples made of 3D-printed copper, as well as 3D-printed ceramics.
Fabricate the copper substrate by 3D-printing with wax and lost wax casting39.
Fabricate the ceramic substrate by lithography-based ceramic manufacturing (LCM) technology40 (see Video 1).
Fabricate the acrylate substrate using a high-resolution polymer 3D-printer37 and remove the supporting wax from the printed part.
Put the printed part inside an oven at 65 °C for 1 h to melt the supporting wax.
After removing the printed part from the oven, put it inside an ultrasonic oil bath at 65 °C to remove the wax from holes, small openings, etc.
Clean the substrates using a wiper wetted with acetone, as possible surface impurities greatly affect the later inkjet print quality.
NOTE: The preparation of AM substrates can be done using different equipment and processes. Depending on the fabrication strategy, the surface and bulk properties may vary as well. It is, therefore, crucial to control these properties using the inspection techniques recommended later (see, for instance, section 4 of this protocol).
2. Fabrication of Interconnects
NOTE: The fabrication of interconnects differs depending on the type (conductive/nonconductive) of substrate.
Fabricate interconnects on nonconductive (ceramic) substrates.
Dispense the low temperature curable conductive adhesive with a time-pressure microdispenser mounted on a microassembly station into the appropriate vias of the printed parts.
Leave the fabricated interconnects to dry for 10 min at 23 °C and with ambient pressure.
NOTE: For the ceramic substrate, the interconnects can also be fabricated using solder paste and high-temperature curing.
Fabricate interconnects on conductive substrates.
Dispense the insulating ink all over the vias' (holes/holes in the substrate) circumference via a time-pressure microdispenser.
Perform the photonic curing using intense pulsed light as suggested by the ink supplier.
Open the tray of the photonic curing equipment containing the substrate table.
Move the copper sample to the substrate table of the photonic curing equipment and fix it using the provided magnetic fixtures.
Adjust the height of the equipment's substrate table to move the sample to the focus plane of the curing equipment.
Close the tray and adjust the curing profile as recommended by the material's supplier for the printed material in the equipment's software interface and press the start button.
Fill the via with low-temperature curing conductive paste (Table of Materials).
NOTE: In general, it is possible to use all forms of one-component, epoxy-based conductive adhesives which are temperature activated.
Dry the fabricated interconnects for 10 min at 23 °C.
3. Preparation of the Inkjet Printing System
Clean/purge the print head nozzles with the purge setting in the printer software, using the appropriate chemical for the respective ink: use isopropanol for insulating inks; use triethylene glycol monomethyl ether for the conductive ink. Purge the nozzles by pressing the purge button in the printer's software interface until the solution ejected from the respective nozzles is clear.
NOTE: The amount of chemical necessary depends on the printer, nozzle, and chemical. In this experiment, approximately 2 mL was used.
Fill the ink containers with approximately 1.5 mL of nanoparticles silver ink with 50 wt.% metal loading and an average particle size of 110 nm using a syringe, for instance, with a 3 mL barrel, and an 18 G Luer lock dispensing needle.
Use one print head to jet the ink by pressing the Start head button in the printer's software interface.
Use the pre-adjusted jetting profile of the printer for the jetting of the conductive ink.
Move the print head to the dropview position using the Go to dropview position option in the printer software interface and observe the jetting of the ink.
Change the parameters of the voltage profile that is preinstalled for the print head and the print head temperature in order to adjust the drop velocity, shape, and volume. Adjust the ink pressure to avoid any spilling of the ink and to reduce the formation of satellite droplets.
NOTE: For the printing system used in this protocol, the operational maximum jetting voltage was set to 40 V and a jetting profile of 1 µs rise/fall time with 10 - 14 µs hold time was used. The silver ink was jetted at 45 °C. The optimum ink pressure is dependent on the ink level. The voltage in the voltage profile has to be increased or reduced depending on the state (e.g., temperature, viscosity) of the ink and the current temperature of the head, as well as the state of the used print head. To achieve proper jetting, we recommend changing the voltage upward in small steps of 1 V. If there is no improvement in the drop shape, reduce the voltage in small steps of 1 V. Follow this procedure until a stable dropping is achieved.
Adjust the printing parameters for the insulating ink in the same manner as done for the silver ink.
Use another print head to jet the low-k dielectric material, which is a mixture of acrylate-type monomers.
NOTE: Again, an operational jetting voltage of 40 V and a 1 µs rise/fall time with 8 µs hold time was used in this protocol. The dielectric ink could be jetted at 50 °C. The optimum ink pressure is dependent on the actual ink level. Generally, the used parameters highly depend on the properties of the ink, as well as of the substrate or layer onto which it should be printed. During the fabrication process, the printing parameters might have to be adjusted dynamically. Please refer to the user manual of the printing system on how to properly adjust printer parameters.
4. Inspection of the Surface Properties of the Respective Substrates for Printability and the Adjustment of Printer Parameters for the First Layer
Perform profilometer measurements to determine the surface roughness.
Put the sample on the substrate table (stage) of the profilometer.
If not homed, home the stage using the home button in the software interface.
Choose the respective resolution and area which is mapped in the software interface.
Place the measurement head at the starting position and start the measurement using the jog option and start button in the software interface.
After the measurement is finished, check the result for consistency (e.g., are the shown heights plausible for the number of printed layers) and save the data.
Perform SEM inspections as per the user manual to analyze the surface quality.
Perform contact angle measurements as described in the user manual of the SEM station to determine the wettability properties.
Fix the substrate on the substrate table using adhesive tape and mark its position appropriately.
Adjust the nozzle and printing parameters in the settings of the software interface by editing the properties of the print head in the printer's software interface.
Again, move the print head to the dropview position using the Go to dropview position option in the printer's software interface and observe the jetting of the ink. If necessary, adjust the printing parameters to optimize the jetting.
Choose a nozzle which ejects well-defined and homogeneous drops of ink for printing.
Enter the number of the chosen nozzle in the printer's preferences.
Perform the drop size tests to determine the size of one printed drop on the respective substrate.
Print a drop pattern, using a known printer configuration.
Determine the achieved drop size using a calibrated microscope or the inbuilt camera system of the printer.
Ensure that the subsequently used printing resolution is appropriate for the observed ink wetting to fabricate a homogeneous and closed surface (e.g., choose a printing resolution of 900 - 1,000 dpi for a drop size of 40 - 50 µm).
Perform an FIB analysis (Table of Materials), as per the manufacturer's instruction, to ensure a sufficient bulk homogeneity for conductive substrates.
5. Curing Parameter Adjustments for the First Layer
Print multiple structures, using a layer of the ink used for the first device layer, onto a dummy substrate (i.e., a sample of the same material which can later be disposed and is used for testing purposes only).
Use thermal curing in an oven at 130 °C for at least 30 min at ambient pressure for the printed conductive silver patterns on a ceramic substrate.
NOTE: Depending on the size of the sample, use a pod to hold the sample inside the oven.
Use the photonic curing for the insulating ink on the metal substrate.
Move the sample to the substrate table of the photonic curing equipment and fix it accordingly (using, for instance, provided magnetic fixtures).
Adjust the height of the equipment's substrate table, using the table spindle to move the sample to the focus plane of the curing equipment.
Close the tray and adjust the curing profile as recommended by the supplier for the printed material in the equipment's software interface and press the start button.
Control the homogeneity of the surface qualitatively using a microscope and quantitatively using a profilometer.
If not homed, home the stage using the respective button in the software.
Choose the respective resolution and area which should be mapped.
Place the measurement head at the starting position and start the measurement.
After the measurement is finished, check the result for consistency and save the data.
Repeat photonic or thermal curing procedures using adopted curing parameters if necessary.
Increase the used photonic energy in small steps of, for instance, 5 V in the software interface of the photonic curing equipment if the achieved resistance is too high. Decrease the used energy if the sample shows signs of burning.
Adjust the equipment parameters for the curing of the first functional device layer so that a conductivity sufficient for the application at hand is reached, but yet no burning of the printed structure occurs.
6. Inkjet Printing and Curing of the First Device Layer
As the first layer is conductive, for the ceramic and acrylate type substrate, use substrate table heating of 60 °C.
NOTE: The temperature must not exceed a temperature which might affect the respective substrate (e.g., the acrylate tolerates only up to 65 °C). This adjustment can be done in the printer settings.
Adjust the nozzle and printing parameters in the settings of the software interface.
Move the print head to the dropview position and observe the jetting of the ink.
Adjust the used resolution of the print head to deposit a homogeneous layer of ink according to the previously determined substrate properties: for low-wettability substrates, for instance, a large contact angle and small drop size increase the printing resolution. Lower the resolution for high-wettability substrates.
NOTE: The adjustment of the printing parameters can be done in the printer settings.
Select the appropriate reference point to print the pattern and store its coordinates.
Load the respective scalable vector graphic (.svg) file and select an appropriate resolution and size, dependent on the desired pattern and the dimensions of the substrate in the printer software.
Perform printing. Repeat the printing of one layer of ink until the homogeneity of the print is satisfying.
Control the homogeneity of the printed layer using a calibrated microscope or using the inbuilt camera system of the printer.
Move the camera of the printer to the print position and observe the quality of the print given in the printer's software interface.
Cure the first layer using the parameters determined in section 5 of this protocol.
For silver ink on a polymer substrate (acrylate, foil), use a 1 ms pulse at 250 V with a reduced amount of energy (525 mJ/cm2).
For silver ink on a ceramic substrate, use heat curing in an oven as recommended with the ink (e.g., 130 °C for 30 min).
Cure the printed dielectric ink at 200 V with 1 ms pulses and repeat the pulses 8x at the frequency of 1 Hz.
NOTE: The spectra of the emitted light used in photonic curing is quite broad (ultra-violet–near-infrared [UV-NIR]). Still, the amount of UV light is sufficient to initiate the photopolymerization and cure the insulating layer.
7. Inspection of the Surface Properties of the Respective Substrates for Printability and the Adjustment of Printer Parameters for Subsequent Layers
NOTE: Please refer to the user manuals of the measurement equipment to perform the profilometer measurements and microscopy inspections.
Perform profilometer measurements to determine the roughness and thickness of the printed layer.
Put the sample on the substrate table of the profilometer.
Choose the respective resolution and area which needs to be mapped.
Perform contact angle measurements to determine the wettability properties.
NOTE: Refer to the user manual of the measurement equipment at hand on how to properly perform contact angle measurements.
Perform drop size tests to determine the size of one printed drop on the respective substrate.
Print a drop pattern using a known printer configuration.
Determine the achieved drop size using a calibrated microscope or the printer's inbuilt inspection system.
Adjust the used resolution of the print head to achieve a homogeneous layer of ink: for low-wettability substrates, for instance, a large contact angle and small drop size increase the printing resolution. Lower the resolution for high-wettability substrates.
Control the electrical properties of the first layer: for a conductive first layer, use the four-point probe to determine the achieved conductivity.
Put the sample on the substrate table.
Lower the measurement head onto the conductive track, making sure the probe has good contact with the printed structure, to be analyzed.
For an insulating first layer, make sure the surface homogenously covers the conductor below. Use a microscope for confirming. Verify the insulating properties using a multimeter.
8. Curing Parameter Adjustments for Subsequent Layers
Print multiple structures, using a layer of the ink used for the next device layer, onto a dummy substrate with an equivalent previous layer.
Use only photonic curing for all substrates.
After curing, control the electrical and structural properties of the printed layer: to determine if the conductivity is sufficient, use a four-point probe measurement.
Control the homogeneity of the surface qualitatively using a microscope and quantitatively using the profilometer.
Repeat photonic curing procedures if necessary.
Adjust the equipment parameters for the curing of the subsequent functional device layer.
9. Inkjet Printing and Curing of Subsequent Device Layers
Fix the substrate on the substrate table appropriately at the previously marked position.
Adjust the nozzle and printing parameters as determined from the previous step.
Select the appropriate reference point to print the pattern and make sure the printed patterns are well-aligned with each other to ensure proper functionality of the device afterward.
Load the respective .svg file with appropriate resolution and size.
Control the homogeneity of the printed layer under a microscope (here, the inbuilt camera system of the printer is used).
Use photonic curing only for the curing of this layer. Use the parameters determined beforehand for an insulating layer or a conductive layer on the insulator.
After curing, control the electrical and structural properties of the printed layer: to determine if the conductivity range of the conductive layer is acceptable, use a multimeter.
Representative Results
From the SEM images shown in Figure 1, conclusions on the printability on the respective substrates can be drawn. The scale bars are different due to the different ranges of the surface roughness. In Figure 1a, the surface of the copper substrate is shown, which is by far the smoothest. Figure 1c, on the other hand, shows steel, a substrate which is not usable for inkjet printing due to the high porosity and unstable contact angle (see also Table 2). In Figure 1b, an SEM image of the bronze substrate is shown, and in Figure 1d, the titanium sample surface is illustrated.
In Figure 2 and Figure 3, the results of the profilometer measurements are given. These evaluations are necessary to determine the surface roughness of the respective substrates. The metal substrates with a roughness well above ~1 µm (aluminum, titanium, and steel) are not usable for inkjet printing, as the ink tends to be absorbed due to the high porosity and, therefore, inhibits the fabrication of homogeneous layers and reproducible structures. The alumina-based ceramic substrate has a comparable roughness, but due to the different fabrication process, does not exhibit such high surface porosities and can, thus, be used.
Drop size tests, such as illustrated qualitatively in Figure 4 and gathered quantitatively in Table 3, give the achievable drop size and, thus, also the wettability properties for the respective substrate and ink combination. Substrates where no distinct drops are formed either have too little wettability (this is true for the AM metals with a low surface roughness), or they are too porous (this is true for the AM metals with a high surface roughness [e.g., Figure 4d]). In Figure 4a, the printing result on bronze is illustrated. Figure 4b shows copper, Figure 4c shows ceramics, and Figure 4d illustrates the steel sample result.
In Figure 5, microscopic images of the results after the curing of a conductive layer of 1 mm width on insulating ink are given. Based on these images, the integrity of the prints can be assessed. For the conductive ink on copper (Figure 5b), the best result can be achieved; the conductive track on aluminum (Figure 5a) is completely destroyed; the conductive tracks printed onto the ceramic substrates (Figure 5c, d) are intact, but show delamination. The delamination is due to the weak heat absorption and high reflection of the substrates. Reducing the curing dose on these substrates yields conductive tracks which have improved electrical and structural properties.
To determine the height profiles and surface quality of the printed multilayer structures, height profiles, which are the results of profilometer measurements, are gathered, as given in Figure 6 and Figure 7, using the profilometer. From these height profiles, the surface homogeneity of the conductive tracks (the smoothness of the blue curves) can be determined. Additionally, surfaces which lost their structural integrity (aluminum, titanium) can be identified by the large gradients in their height profiles.
The FIB analyses with copper (Figure 8a), bronze (Figure 8b), titanium (Figure 8c), and brass (Figure 8d) are shown to illustrate a sufficient bulk homogeneity of AM metal substrates. The scale bars are different here in order to optimally capture the structural characteristics of the multilayer prints (deficiencies in homogeneity, conductive track, etc.). This ensures sufficient electrical conductivity of the substrates so that these can be used for shielding in magnetic and capacitive sensing applications. Results for the achieved sheet resistance using a four-point probe are gathered in Table 4. Additionally, a qualitative assessment of the printed layers is possible. The granular structures are formed by cured nanoparticles and the layer below is the insulating ink. In, for instance, Figure 8b, we see nonhomogeneities (holes, air inclusions) in the printed layers. These result from outgassing during curing. Outgassing can occur when the cure dose for conductive ink on insulating ink is too high. This effect negatively influences the integrity of the printed structures, and excessive outgassing leads to destruction.
In Figure 9, measurements results are shown. These results are gathered using a demonstrator which employs a capacitive sensing principle. The smoothness of the curves illustrates the high achievable quality despite the structural deficiencies that might result from the printing processes.

A way to fabricate multilayer sensor structures on 3D-printed substrates and on foil is demonstrated. AM metal, as well as ceramic and acrylate type and foil substrates are shown to be suitable for multilayer inkjet printing, as the adhesion between the substrate and the different layers is sufficient, as well as the respective conductivity or insulation capability. This could be shown by printing layers of conductive structures on insulating material. Furthermore, the printing and curing processes for all layers was successfully performed without impairing each other.
The fabrication strategies presented in this work are highly sensitive to the interplay of the different materials and surface properties. Consequently, the reproducibility of the performed steps is dependent on the respective manufacturing process. For the preparation of the used AM materials, it needs to be considered that the surface and bulk properties may vary significantly depending on the fabrication method (Figure 1 and Table 2). For the inkjet printing, the proposed parameters have to be carefully adjusted to the used printing system, as well as to the respective inks42,43,44. The jettability of different Ag nanoparticle inks may vary significantly, depending on the formulation. This means that the ink's solvents and certain additives determine its specific viscosity, surface tension, and boiling point.
Another point to consider is the agglomeration of solid content when the ink ages or is not stored properly, which can distort the jetting quality. Besides that, the specific set-up of the print head itself is also crucial, especially the dimensions of the nozzle opening. It determines the actual jetting parameters, such as the jetting voltage, waveform, and temperature setpoint, as well as the resulting drop size (Figure 4 and Table 3). During the printing process itself, a heated substrate table might also increase the temperature of the print head because of the spatial proximity, resulting in a change and possible degradation of the printing behavior. Therefore, it is crucial to monitor the print head temperature during processing.
Another factor which might influence the jetting behavior during printing is the ink pressure as it might have to be decreased as the ink level lowers during processing. The fabrication of the interconnects on a conductive substrate is not trivial, as the dispensed insulating layer has to have a sufficient thickness to avoid short circuits, but still needs to leave sufficient space to form the interconnects using conductive solder paste.
Furthermore, the adhesion between the three materials has to be acceptable to form stable vias. During the curing process, the temperature tolerance of the insulating layer needs to be considered as well. Therefore, low-temperature curing solder paste has been employed for the respective interconnects. After printing the functional layers, they need to be cured to yield the desired sheet resistance (Table 4). Thermal sintering is an appropriate and effective method for the silver patterns if the substrate or the underlying layer has a sufficiently high-temperature tolerance45. This is not the case for the insulating layers, which is why photonic curing is employed (Figure 5). During the photonic curing process, a large amount of energy is transferred to the sample. Therefore, it is crucial to ensure that the printed patterns have sufficiently dried before the curing process as, otherwise, the remaining solvents might reach their boiling point and may destroy the printed layers due to liquid expansion and the formation of bubbles (Figure 8).
Furthermore, sufficient drying is necessary to create layers of homogenous thickness (Figure 6 and Figure 7). Homogenous thickness is necessary for applications where nanometer measurements based on, for instance, a capacitive principle is employed (Figure 9). Here, a uniform distance from the sensing electrode can significantly affect the quality46.
Overall, it can be stated that the choice of optimal photonic curing parameters for the device layers on an insulator is a crucial factor: if the introduced energy is not sufficient, the conductive ink remains unsintered and the sheet resistance is too high for the devices to be electrically functional; by introducing too much energy, excessive heat will be produced in the film and, consequently, the conductive track is destroyed. The copper substrate yielded the best result in terms of sheet resistance (see Table 4) and also in the achieved surface quality and integrity of the printed metal track. This might be due to its surface roughness being the lowest among all considered substrates. The substrate reflectivity could be identified as influencing the photonic curing result significantly. The respective substrate reflectivity has to be considered in the curing in order to achieve an optimized result with respect to the applied photonic curing spectrum and profile. This has to be adapted for individual substrates and ink combinations.
In this work, the suitability of AM substrates and foil for inkjet printing was demonstrated. Additionally, the material properties together with the factors essential to the process were determined. A strategy to fabricate working sensor prototypes on foil and AM metal and polymer substrates was presented. Finally, the achievable measurement quality based on measurements done with a demonstrator system was shown. This approach forms an important contribution to the future electrical functionalization of surfaces, enclosures, and other structures that have had a solely mechanical purpose in the design of numerous devices so far.

Q: Not able to install scikit-learn on Raspberry Pi 3 B+ I was trying to install scikit learn on Raspberry Pi 3 B+, with code,
python3.8 -m pip install scikit-learn==0.23.2
initially the pi was working fine showing the progress, after above 1 hour, monitor went off and the green LED on Rpi is ON all the time (before it was like blinking).
Now the Rpi seems to be ON with red and green LED full time ON, and not able to see the progress, and not detecting the input given through keyboard and mouse. its about 5 hours.
it will be very helpful for me, if someone explains me why this happens.
Thanking you in advance.

Robyn Hitchcock's Eponymous 21st Album is an "Ecstatic Work of Negativity"
By Terence Praet April 24, 2017
Robyn Hitchcock - "Raymond and The Wires" (Official Video)
Twenty-one studio albums into his career, Robyn Hitchcock has released a self-titled record. In recent interviews, when asked about the album's title and why he chose to release an eponymous record so far into his career, Hitchcock has suggested Robyn Hitchcock is an introduction to his music. "Think of me as a new act – I'm only 63. People always ask me, 'where should I start listening to your records?' I'm a train with many carriages. I thought, I'll just make this record and if people like this one, then they'll probably like the others. If they don't, it's not worth them listening to any of them, really."
The album originated in 2014, following Hitchcock's move to Nashville, Tennessee. Friend and neighbor Brendan Benson offered to produce the record, with a single caveat: to make it sound like the Soft Boys.
"I said, well, I could use the same instrumentation," Hitchcock notes. "Two guitars, bass, drums, and harmonies. Which obviously is the template that comes from the Beatles and Big Star and the Byrds, all of those groups that the Soft Boys were nourished by. But of course I'm not fueled by the same nutrients anymore." The resulting album is Hitchcock's liveliest record in years. The track "Virginia Woolf" draws on the sounds of the Soft Boys, per Benson's request, while tracks like "Mad Shelley's Letterbox" and "Time Coast" recall the alt-pop of Hitchcock's time with The Egyptians, and others still evoke his quieter solo albums like I Often Dream of Trains.
Expanding on the comment that he's "not fueled by the same nutrients anymore," Hitchcock adds"I don't have the same anger that I had as a 25 year old." This is clearest in Hitchcock's lyrics. Robyn Hitchcock's opening track, "I Want to Tell You About What I Want," (and originally titled "My Vision of World Empathy") talks Hitchcock's vision for the future of humanity: "I want world peace / Gentle socialismo / No machismo / And the only god shall be / The god of L-O-V-E /I want a non-invasive kind of telepathy / That let's you feel what it's like to be somebody else." The song never ditches Hitchcock's off-kilter sense of humor, however. The next verse speaks of the eventual domination of the world by cats.
Hitchcock describes his latest record as "an ecstatic work of negativity." His description of the album is apt. Even with the darker, cynical currents of the lyrics, the album is full of energy. To give Hitchcock the last word, "I've been making autumnal records since I was 30. Now I'm past the autumn of my life so I've decided to start making spring records. I can't be bothered to sound as ancient as I am."
Robyn Hitchcock is out through Yep Roc Records and available on Amazon, iTunes, and the Yep Roc store.
Writer's Note: In addition to contributing to The Manual, I work at a music promotion company, Distiller Promo, that is currently promoting Robyn Hitchcock.

Originally published April 1, 2012.
I'm waaaaay past sarcasm. Proactive activity rules my world, kids still rock my world.
Guess what? April Fool's to us! Scooter isn't autistic after all! ;~/ I'd like to share the fantastic news with some of those who helped us along our terrifying journey of discovery and knowledge.
Thank you for holding my hand with warmth and concern when my son was young and I questioned his development appointment after appointment. It turns out all 6 of you were right! He really is just an active boy who will settle down in time. Boys do develop slower than girls, especially in speech and behavior. His motor skills would strengthen by doing the 2 basic activities you mentioned. And yes, he did look at you briefly when you said his name! I understand your refusal to do further testing to promote early intervention. Waiting until his rapid developmental toddler years flushed out his worrisome behaviors was a much better approach. I tried not to read all that scary information on the internet that angers you so. I know that if it was you you'd just sit around and wait for the experts to inform you of your child's troubles. Boys don't communicate as well and often take risks.
I guess I was just paranoid because from day one of my pregnancy your local sister ob/gyn group warned me nonstop about the high risks associated with older 40+ pregnant woman. All those statistics, articles, lectures were wrong about the dramatic increase of birth defects with older mothers. I'm so glad that I didn't let them perform all those intrusive, risky tests. The precautions I took coming in twice weekly to monitor his development must have worked, so really - why bother checking his performance after birth?
I also appreciate how you ignored the way Scooter always ran up and down your hallway, opening doors to see other patients. He's really just a caring soul who wanted to see why the babies were crying. All those babies in the waiting room must have been hungry or crabby when he poked their eyes or took off their little caps before I could reach him. He is a bright curious boy. I tried to console the children that he took toys and trucks from, and unthinkingly pushed out of the way from his play routine - it must have been their nap time. Anyway, I just wanted to offer my sincerest gratitude for placating me and offering the finiest in quality pediatric healthcare during my difficult time as a new parent.
Like our pediatrician group, your shared the belief that children really don't need evaluating until they are kindergarten age. I appreciate you discouraging me from my worry by giving me prices and breakdowns of the many appointments we'd need. It helped me to realize that despite the professional directives advocating for early intervention, most children don't get evaluated until they pass the stages of development that could be subject to varied degrees of normal. Each of his behaviors could be attributed to growth stages. All kids go through stages that appear unusual, but of course I'd forgotten in the 5 years since my other 2 children were babies. I considered listening to your advice, but finally had to set my worries to rest and get him evaluated after he lost his speech and started punching and kicking me, then his big sister. And of course there was the running into the street or parking lot the hundreds of times, and getting lost in public. But of course you knew, because I'd told you all of these concerns.
What you didn't tell me was that each of these behaviors was listed in the standardized ADOS Autism Screening test. In fact, in the huge hours-long, 100+ question booklet interview, Scooter had 3 ASD behaviors that didn't apply and that he didn't do. So he must not be ASD, simply developing differently or perhaps had some sensory and communication issues.
Thanks for your patience with a paranoid mom and her active son. It turns out he is just like his dad's side of the family who are hyperactive, never-sit-still kind of go-getters. And like I heard so often, Einstein didn't talk until he was 4, or was it 6? In fact, I have read statistics on how many autistics are brilliant, savant-like geniuses like RainMan. Gosh I hope we're in that 10%. Yup, that's all.
Thanks to all who pulled together at group activities and took care of my other kids while I frantically chased Scooter. You have no idea what a comfort it was to me to know my other kids were safe and having fun when you stepped in. Thanks for making it a joke to him by asking, "Are you hiding from your mom again?" with a grin. I loved chasing him and needed the exercise of course. Oh how I laughed and laughed when so many suggested an invisible fence with a handheld zapper for him, I don't know WHY they haven't invented it yet. Or wait, isn't that a Tazer?
I especially want to thank the close friend who helped me one day after my teary, breathless, frantic frightened outpouring about Scooter's frustrating behaviors, screeching cries, roughness and non-stop destruction. It helped me so much when you matter-of-factly told me, "Well, he's not a monster!" It was a great wake up call because I could have gone down the path of mistakenly thinking he was. Duh. Like I really give out those vibes in my weary desperation. I love friends who understand. To her benefit, I don't complain to NT parents much. She probably got smacked with too much reality.
Thanks so much for your kind, patient ways with my beloved son. I realize he had potty issues and he would pee or poop daily while in your class. I thank you for not wanting to take part in positive supports because he needed to learn like everyone else and was supposed to before entering your school. We really don't know why he took a backslide under your tender Christian care. I loved hanging around to wait for your call so that I could change him, with you tsk-tsking and reminding me to take his soiled diapers with me (like I ever would leave them?), in front of other parents. Your frank approach was just what I needed, and what my special needs son needed.
I particularly appreciated the way you finally called in an exasperated tone and asked me to meet formally. I was certain that this time when I asked if he was kicked out you'd say YES! instead of the usual, "not yet" with a smug look. Your no-holds-barred approach was helpful. It was great to know that you'd all gotten together to discuss his problems at length without me. The itemized list you recited without pause for me to question, to understand, to digest - just perfect and very helpful that it was scrawled on a scrap of paper so that I couldn't review it later when I wasn't under duress. I knew that you had a strict timeline of 10 minutes to educate me on my son. I was grateful when my tears flowed that you yelled out from your seat through the open door for someone to bring Mrs. Perky some tissues, disturbing the quiet classroom. I really didn't want comfort or kind words, it would only make me weep and you instinctively knew this somehow. It was a bit embarrassing to emerge teary and blotchy at pick up time, with questioning stares. But, it did get Scooter to recognize my tears and sadness, a social skill that he usually doesn't have. He even offered me tissues as I sobbed in the parking lot.
I have so many other helpful individuals/professionals to sarcastially "thank", but I must go. I need to purchase my blue light to proudly display in my porch lights on April 2. I need to get back to my positive works promoting awareness, acceptance and support for families affected by autism. I need to nurture our relationships with caring friends, relatives and professionals who have helped prop us up in this journey. I need to pull my family close and proclaim a GH, where we all huddle together in a GROUP HUG!

Stolen gauge holds radioactive material, police agencies told
by Ashton Eley | January 13, 2021 at 7:02 a.m.
A gauge containing radioactive material was recently stolen from a residential driveway in West Memphis, according to the Arkansas Department of Health.
The department's Radiation Control Section received notification Tuesday about the missing gauge, which is not dangerous if it remains intact, a Health Department news release said.
However, the gauge could present a radiation hazard if it was damaged and the radioactive sources were exposed or removed from their sealed container.
"The gauge in routine storage does not pose a significant health hazard," Health Department spokeswoman Danyelle McNeill said in an email.
Although the gauge poses a potential public health risk, it does not contain enough radioactive material to be used for any explosive device.
The gauge transport case is about the size and shape of a storage trunk and is made of hard yellow plastic material with handles on each side and on top. The gauge itself is also yellow with a rectangular base and a foot-long handle on top. Both are clearly labeled as radioactive materials. In all, it weighs approximately 85-95 pounds, according to the news release.
The Troxler Electronic Laboratories Model 3411-B gauge is used to measure moisture and density in the soil. It's serial number is 4794, according to the report.
"People who hold these are licensed to have them as part of their job," McNeill said.
The department requires licensed individuals using portable gauges to use a minimum of two independent physical controls that form tangible barriers to secure gauges from unauthorized removal whenever they're not under the control and constant surveillance of the licensee, she said.
The Health Department notified Arkansas State Police, local government officials, law enforcement agencies, the United States Nuclear Regulatory Commission, the FBI, the Arkansas Crime Information Center and the Arkansas Division of Emergency Management.
Bill Sadler,a State Police spokesman, said that state troopers had been made aware of the theft, but he directed questions to the Health Department and West Memphis police.
West Memphis Police Chief E. C. West did not return a call and message left around 3:30 p.m. Tuesday.
The FBI also declined to answer questions about a potential investigation into the incident.
"We can't comment on the existence or nonexistence of any investigation," said Ryan Kennedy, supervisory special agent.
Similar incidents of lost or stolen radioactive material have happened several times before in Arkansas and across the nation.
On Feb. 19, 2007, another radioactive Troxler Model instrument was stolen from the back of a truck parked at a Walmart in southwest Little Rock, according to an Arkansas Democrat-Gazette report at the time.
Both the gauge reported stolen Tuesday and in 2007 contain a source of Cesium 137 and Americium 241.
Americium 241 is a man-made radioactive metal and poses a significant health risk if ingested or inhaled.
"Once in the body, it tends to concentrate in the bone, liver and muscle. Americium can stay in the body for decades and continue to expose the surrounding tissues to radiation, increasing the risk of developing cancer," according to the United States Environmental Protection Agency.
Cs-137 is produced by nuclear fission and is also used in some medical devices, according to the Centers for Disease Control and Prevention.
"External exposure to large amounts of Cs-137 can cause burns, acute radiation sickness, and even death," according to the CDC. "Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation."
Ingesting or inhaling Cs-137 would allow the radioactive material to be distributed in the soft tissues, especially muscle tissue, increasing cancer risk, according to the CDC.
There have been at least five other incidents of radioactive material being lost or stolen: Sept 28, 2005; November 16, 2000; June 15, 2001; Oct 29, 1998; and July 31, 1996.
The United States had more than 1,300 incidents where sealed radioactive sources have been lost, stolen, or abandoned from 1998-2003, according to the U.S. Government Accountability Office.
Since then, several laws have been passed in attempts to to enhance control of dangerous radioactive materials, but vulnerabilities remain, according to the latest GAO Nuclear Security report in 2016.
Materials used in the industrial and medical fields make up most of the 1,040 reported incidents between 2013-2018, according to the CNS Global Incidents and Trafficking Database 2018 Annual Report. Transportation creates the greatest vulnerabilities, accounting for 41% of total incidents in 2018.
Two of most dangerous common radioactive materials are Cesium-137 and Americium/Beryllium-241, which are featured in approximately 23% and 26% of 2018 incidents, respectively, according to the U.S. Department of Health and Human Services' Radioactive Emergency Medical Management.

Paintball is a game where you shoot at each other with so-called paintball markers. When you hit an opponent, he/she is then "marked" and out of the game. There are many different kinds of games. A typical game takes about 4-10 minutes depending on the number of participants. Paintballs are made of gelatin capsules containing water-based paint, which can be washed from the clothes within three days.
Are there age restrictions on paintball?
How many paintballs do we need for a game?
Do you sell packages with an unlimited number of paintballs?
No. These packages are not good value for money for you. Some paintball companies will try to rip you off by selling "unlimited paintball packages" that you will not have time to use up before the game is over. At Paintball Arena we believe in giving you the best possible experience, rather than overcharging you. You only pay for what you have ordered, and if you run out of paintballs halfway through, you can always purchase extra.
No. It is forbidden to bring your own paintballs to Paintball Arena, as it poses a safety risk.
In most cases, no. But it depends on where on the body you get hit. The worst shot is still bearable and we have not yet seen crying or similar due to getting hit. At Paintball Arena all players wear a mask, gloves and a freshly washed suit that protects from the pain. The mask protects the face, and therefore it is no more dangerous than other sports.
No. Unfortunately it is not possible to come and play alone. Instead, pick your own team of at least 8 people for paintball, climbing relay or teambuilding, and 10 people for all other activities. Consider bringing a group of friends or write on our Facebook page, where sometimes others are also looking for people to play with.
Can I join a paintball club?
We recommend being in good time in order to be sure to find a time that works for you. We are usually fully booked on Saturday so if you want to play on a Saturday, it is even more vital that you book far ahead. You can easily reserve a time, even if you do not know the exact number of participants.
Do we have to pay for a minimum number of participants?
Yes. To play paintball you must pay for a minimum of 8 people. For other activities you must pay for a minimum of 10 people. It may be possible to be fewer participants, so long as you pay the price for the minimum number. Example: 5 people would like to play Human Football (price per person DKK 125). The minimum price would therefore be (DKK 125 x 10 =) DKK 1250, so, per person, DKK 250.
How can I find out if the day we want is available?
Send a booking request on our website and you will get a confirmation back if the chosen time is available. If the time you want is fully booked, we will contact you to find another time.
What happens if we have last minute cancellations or new additions to the group?
If there are one or two cancellations or new additions, it does not matter. You pay on the day, so the price is simply adjusted accordingly. Remember that you will always have to pay for a minimum of 8 people for paintball and a minimum of 10 people for other activities. If the number in your group changes a lot – we would appreciate that you notify us by email or phone.
Yes. To confirm your booking you must pay a deposit of DKK 1000. The deposit is the same for all activities regardless of the number of participants. It must be paid at least 14 days before the event. If the activity is more than 28 days in the future, the deposit must be paid latest, 14 days after you have made your booking. You can pay by credit card or MobilePay via the payment link in your confirmation email. Alternatively, you can make a bank transfer to the Reg. 2232 and Account 3485790836. Remember to enter you customer number in the comment box if you use this option.
You pay the rest at Paintball Arena on the day. We accept credit cards, including most foreign cards.
Can we get our deposit back if we cancel our reservation?
Yes. But be aware that you must cancel no later than 10 days before your activity is due to take place in order to receive your deposit back. If you cancel after this deadline, we will withhold the deposit. You can, however, reuse it if you wish to book an activity again within the following 3 months. If you cancel less than 48 hours before the activity is due to take place, the deposit will not be refunded – and it cannot be reused on a different date. Cancellation must be made in writing to info@paintballarena.dk or orally by calling (+45) 32 95 35 35. Please have your booking information ready when you cancel. If you cancel by sending us an email, please include your customer or booking number.

Do You Need A Speaker for Your Event or Meeting?
Sometimes the most important lessons come when you're not even looking for them. My dad was my hero, and he taught me many, many lessons about life and business – they just came within the context of racing stock cars together. Dad passed away in 2015, but his lessons will live with me forever – and now I want to share them with you. In this one hour, you'll experience fundamentals that will help you build the kind of environment and culture that makes for a successful business – and we'll have a little fun, too.
Smart Sales Hiring – You can't get the right results with the wrong people. This program teaches the tools and techniques I have used to generate over an 80% win rate in hiring salespeople and sales managers.
The Unconventional Secrets of Getting the Most out of Your Salespeople – Too many managers believe that sales management is simply a process of hiring, firing, discipline, and activity counting. However, the path to maximum performance lies in your sales manager's ability to positively change the behavior of his or her salespeople.
Troubleshoot and Coach Sales Performance – In this program, we get into the nuts and bolts of how to diagnose sales problems from a qualitative and quantitative perspective and have meaningful coaching sessions with your salespeople.
Managing Engaged Salespeople – The best performance comes from salespeople who are engaged in their work – the ones you don't have to prod and motivate to do the job. However, recent surveys show that only about one of every four salespeople is engaged. This program shows how to engage salespeople from the start, keep them that way, and re-engage disengaged salespeople.
I Just Hired a Salesperson – Now What? Onboarding For Sales Success – The first ninety days after you hire a salesperson will determine their chances of success, so don't shortcut the onboarding period! In this program, I'll teach how to build an onboarding program that works and monitor your salesperson's progress.

Name Your Price – and Get It! – Salespeople are their own worst enemies when it comes to price and profit. I show how to protect your profit through the proper price-selling techniques.
Make Your Net Work – Face to face networking is nearly becoming a lost art; too many people regard social media as all the networking they need. Real relationships that bring real referrals still include face to face networking. This program will teach how to optimize face to face networking and use social media to maximize your face to face relationships.
I Just Got Hired – What Now? How to Launch Your New Sales Job – The first ninety days are a huge determining factor of your sales success. Designed for new hires and those who manage them, this program will serve as a guide to long term success.
Hippies and Hipsters: Sales Team Success Across the Generations – If there's any constant in selling, it's change. From Boomers to Gen-X to Gen-Y to Millennials to Gen-Z, every generation has their own unique tendencies and traits, and preferences in communication. What doesn't change is the need for your company's objectives to be met. In this program, we'll help different generations learn to communicate with each other and win in selling.
Storyselling, Parts One, Two, and Three: To Thine Own Self Be True, Take the Money and Run, and Your Hero's Journey – If you really want to elevate your selling game, you need to learn the art and skill of Storyselling. Using story as a way to connect, engage, and sell your customers will greatly increase pull-through in every part of your sales funnel, and this three-program series will teach you how.
I can also work with you to develop custom programs that are directly targeted to your members' environment and learning objectives.
There are many more topics on selling, sales management, and leadership available. I can do Keynote sessions as well as Breakouts, and Sales Meetings.
