The sensor is one of the most promising fields for application of nano-metal particles. The characteristics of nano metal powders such as large surface area, high special activity and extra tidy is consistent with multi-functional, miniaturization and high-speed required by the sensors. In addition, as the sensor material, it also requires broad functions, high sensitivity, characteristics of fast response, wide detection range, good selectivity, high resistance, stable and reliable. Nano metal powder can better meet the above requirements.
In the chemical industry, nano-metal powder used catalysts, nano-materials to show their talents on the one hand. Such as ultra-fine boron powder and chromic acid ammonium powder can be used as explosives effective catalyst. Ultra fine platinum powder and tungsten carbide powder is efficient hydrogenation catalysts. Fine silver powder can be used as a catalyst for ethylene oxide; ultrafine nickel powder, silver powder light sintered body as chemical batteries, fuel cells and photochemical cell electrodes can increase the contact area between the liquid or gas. It also increases cell efficiency and becomes miniaturization.
Light sintering of the ultrafine metal powder porous filters can be generated as the adsorption of hydrogen

There is a growing demand for energy efficient technology around the world. There is a reasonable fear that conventional sources of energy like coal will not last long. Naturally, there is a thrust for alternative options like solar energy, wind power and so on. However, due to certain bottlenecks these new age power generating options have not become fully operational yet. But thanks to cutting edge inventions, in this field, we can hope for better prospects in the near future. New research works in the vertical of semiconductor nanostructures (nano flakes) has shown bright sides in this regard. It will no doubt add pace to the endeavor for deriving clean energy from the Sun and help improving the practicality of solving the power crisis in the future world. Solar energy efficiency has reached to new heights, riding on nano flakes.
Martin Aagesen is a premier in the research of this revolutionary nano flakes technology (PhD from the Nano-Science Center). There is a huge expectation that his “future solar cells” will deliver the desired outcomes. If that happens then there will be a giant leap towards improving the world’s capability
Nanotechnology has been introduced as advance technology in all fields of applications like electronics, agriculture, textile, plastics, aerospace and medicines due to its nanomaterials. These nanomaterials include Carbon nanotubes, graphene, silver nanoparticles and gold nanoparticles. But carbon nanotubes and graphene are the current interest of research area due to their advance properties mechanical, chemical and multifunctional and applications in electronics, textiles, agriculture, plastics and drug delivery system. In pharmaceutical area there are some problems related to its pharmacokinetics absorption, Distribution, metabolism and elimination.Mostly drugs are taken in oral, liquid and injection form. By these methods there are many problems related to its metabolism, toxicity and elimination. Drugs are released in an uncontrolled manner and released in a short time and require more dose.
Nano scaled drug carriers have been emerged as an intermediate of nanotechnology and drug delivery including carbon nanotubes, graphene, iron nanoparticles and liposomes and But MWCNT and Graphene have advance properties rather than other nanomaterials. So, these nanomaterials can be used to overcome these problems. These drugs can be delivered to the body by attaching with the MWCNT and Graphene. Pristine MWCNT have some toxic effects but functionalized MWCNT and Graphene have no toxic effects. We can release
A nanowire is basically a part of nano particle; however this tiny thing includes massive properties to be used in wide array of applications. One can come across different kinds of nanowires, they are used specifically in different purposes. New methods of production of nanowires are being found out, which can result in a wider scope.
The nano sized wires are too tiny to watch out for. These are basically composed of different kinds of metals such as gold, iron, silver or of semiconductors like germanium, zinc oxide and silicon. The scientists make use of nano particles to bring nano wires into account, which are small as well of about 3 nm diameter.
The synthesis procedures of the nanowire is as same as that of nano tubes, however there is a requirement of catalyst particles in heat chambers. In order to develop gallium nitride nanowires, the researchers are making use of vaporised gallium with nitrogen gas in the chambers. The particles of iron get vaporised first and then work as catalyst. The nitrogen and gallium particles get mixed with iron. After getting mixed, they come over the surface and form into a nano wire.
When there is development of nanowire, the components must
Hey, guys, have you asked yourself that what’s the significance of our every 24 hours, what is the essence of our life. Are you in a fog? Have you gotten an answer and what is it? Have you talk about the title of life significance with your friends? Are you reach a consensus?

Most of the major companies for cosmetics are manufacturing nanotechnology products. They are usually used in famous products such as sunscreens and anti-aging products. But what does nanotechnology really mean? Actually it is a field of science and technology which aims to control matter with regards to molecular and atomic levels. It can make compounds too small and therefore delivers quicker and more effective results. It can also make products cleaner, stronger, lighter and most of all less expensive. However, you should understand that this particular type of technology is not yet thoroughly tested which means that it is not certain if it is really safe most especially if you apply it in the most delicate part of your body such as your face.
The FDA has not yet made a lot of research about this. It seems that there have been no reported cases of adverse effects yet. However, there are some experts which are wondering about the safety of these products since when particles will become smaller, new chemical properties will emerge. Since these nano-particles are very small then they can quickly slip through your skin layers. This means that it will have an interaction with your bloodstream and
The term “Nanoparticles” is often heard these days, and with good reason. Nanoparticles can be used in a wide range of applications, helping companies across a diverse spread of industries reduce their costs and increase the efficiency of many of their processes.
A nanoparticle can be defined as an extremely small object that behaves just like a singular unit. In the case of silver nanoparticles, some are composed not just of silver but also of a large percentage of silver oxide. This is due to the large ratio of surface-to-bulk silver atoms, which react directly with oxygen. This is a reason why the size range of silver nanoparticles can vary between 1nm and 100nm.
The reason nanoparticles provide such interest to many different people and industries is the distinct properties that nanoparticles can have compared to the properties of the same material in bulk. The distinction is that with materials in bulk, the physical size and the numbers of atoms are largely irrelevant. However, nanoparticles do not behave in the same way. The size of a nanoparticle is often directly proportional to the number of atoms the substance has. This change in the number of atoms present can lead to radical changes
When the science stream developed years ago, scientists started experimenting with new chemicals in order to create many more chemicals to be used for various purposes. However, not all scientists knew that their created chemicals would create such expansion for the people. Now, it has become very easy for the people to perform in every field of the work. Whether someone is cooking, or someone is teaching or working in the industries, chemicals play a vital role in their job.
Every chemical has different properties which are usable in different categories of work. Not all properties are similar; they differ in terms of colour, structure, size, composition and sometimes in shape as well. There are many scientists who buy sulphur nanopowder as it has made many developments possible not just at the personal level, but in terms of commercial purpose as well.
Why should one buy sulphur nanopowder?
Sulphur nano sized compounds or powders are such elements which are used in multi purposes including in medicines, cosmetics, garment industries, agriculture and many more. There are lots of advantages of using sulphur powder, some of them are mentioned below.
The powder is used in dyes, mineral extraction, matches, filter water, agrochemical industry, alteration in CNTs,
Whenever it comes to the nano technology, it usually means dealing with objects or elements having size in the order of nano meters. There are numerous elements present in the world of nano technology, such as nano rods, nano wires, nano spheres, etc. Among the different elements available, the nano wires are the most important one for the electronic industry.
With more and more studies are being carried out in the field of nano technology, different applications of nanowires are being uncovered. There is no doubt that in the next few decades, nano wires would completely change the face of the electronic world. It will shrink down the sizes of the electronic devices by significant amount. No doubt, in the very near future, more and more company would buy nanowires to meet their manufacturing requirements.
For those who do not know, a nanowire is actually an extremely thin wire, having diameter of just few nano meters. It is interesting to note that the ratio between the length and diameter of the nanowires can be like 1000 is to 1. While the diameter can be up to tens of nano meters, the length can be unconstrained. The quantum mechanical properties of these nano
The multi walled CNTs have the capacity to be used widely in material sciences, engineering and medical applications. The high durability feature and needle shape of the MWCNTs makes it usable in asbestos pathogenicity. As per the recent researches, the multi walled CNTs can induce in different reactivities. In addition, physicochemical potentialities of the tubes show carcinogenicity and cytotoxicity in the cells which still remain unclear.
The diameter of the multiwalled carbon nanotubes are approximately 50 nm and have crystalline nature. However, when the tubes are too thick with 150 nm diameter then these are not much toxic as others. Also, they are less carcinogenic and less inflammogenic. Some of the intrinsic features of MWCNTs can cause harmful effects on both extracellular and intracellular paths. Such connections can even change the signals between cells and offer negative effects such as death of cells, reactive oxygen production, cytokine releases, lysosome injury, and apoptosis.
The micronuclei numbers in lung cells can rise in number when related with multi walled carbon tubes; this can in turn lead to chromosomal damage and other spindle disruption. There are many studies going on over the element and with every experiment, something new is being found out.

Similar to the structural and physical properties of graphene, hexagonal boron nitride is a material which has become popular due to its lubricating properties and its inert nature for salts and molten metals. As a mould releasing agent hexagonal boron nitride is used in a large scale and also in improving the strength of powdered composites. Popularly this product is termed as white graphene.
A brief history about hexagonal boron nitride During the year 1840s, the hexagonal boron nitride was first created by an English scientist named W.H Balmain. The first experiments created a boron nitride which was unstable in nature. Due to various technical difficulties, problems in the process of production and the cost associated with it, the material remained at a laboratorial stage. Later this year, Union Carbide and Carborundum companies were successful in making an industrial usage of this material.
Applications of hexagonal boron nitride in its powder form are:-
The uses of Hexagonal boron nitride are found in various chemical, metallurgical, electro technical and electronics sector.
It is used in the creation of electronical parts like heat sink, coils, and substrates and in various prototypes.
In bearings of high temperatures the hexagonal boron nitride is used as a solid

Solar energy system is source of free electricity generation but producing them is highly energy- extensive process. One of the biggest challenges in producing this free electricity is lowlight hours and hazy skies. Country like Germany is biggest manufacture of solar power in Europe as per gross domestic product but focusing on country like Bulgaria we see that Bulgaria produces 4 times as much as their domestic product toward solar which is extremely huge.
Bulgaria was the leader in Eastern Europe in design and fabrication of solar thermal installations. 66% of technical Bulgarian solar potential belongs to active solar thermal energy systems. During the last 10 years Bulgaria faces the rapid price hike in electricity, liquid fuels and heat. The major solar cells are installed in public and industrial buildings. Bulgaria sustained not only solar energy system but chances of wind mills across Varna and Bourgas is also very higher for generation of free electricity.
As said, there are two major bio-energy sources, wind and solar but if we keep them aside we will see Bulgaria has enormous cattle farms including the wastes coming out from industries, homes, hospitals and natural wastages. Bio gas plant can play a vital role in implementation
The favor of pets of human beings has been for a long time such as docile dogs, furry kittens and other cute animals. People love fresh and adorable animals and like to keep them at home. The development of technology brings us the surprise. When researchers do experiments with animals they found something new–the transgenic pets.
At the first time researchers do this for research convenience of human disease. However, the result is beyond imagination: they found the gene-editing animals are more adorable and suitable as a pet. Recently, a new pig named Bama was sold as pets in China. By TALEN technology(the powerful tools for gene editing just as the CRISPR Cas9 and ZFN), this ‘micropig’ has a smaller size, weighing about fifteen kilograms when mature. The black and white color and the tiny figure make it more sweet.
The researchers said that they do this for the study of Laron syndrome, a kind of dwarfism caused by gene mutation. In fact, this is not the first case. In 2011, this company had introduced some transgenic pigs, but they didn’t put it into market. At the same year, US researcher, Eric Poeschla, developed fluorescent green felines. The immunodeficiency virus of rhesus
Ionic liquids are considered as great electrolytes for electrochemical energy. The liquids used in super capacitors include pyrrolidinium, imidazolium and asymmetric aliphatic quaternary ammonium salts of anions such as trifluoromethanesulfonate (Tf), tetrafluoroborate (BF4), hexafluoro‐phosphate (PF6), bis(trifluoromethanesulfonyl)imide (TFSI) and bis(fluorosulfonyl)imide (FSI). In addition to this, they are also utilized in lithium ion batteries. These batteries consist of organic solvents with a dissolved lithium salt such as lithium hexafluorophosphate.
Ionic Liquids in Super Capacitors
Super capacitors, also known as electrochemical capacitors (ECs) are power leveling storage devices. Reduction and oxidation of electro active polymers, carbonaceous products or metal oxides are utilized for the purpose of storing energy. An increase in the capacitor voltage causes a significant enhancement of power and energy. Ionic liquids are used in super capacitors as a replacement to aqueous electrolytic solution to enhance the capacitor voltage with lower capacitance values. Due to higher decomposition potential, ionic liquids are able to enhance the capacitor voltage.
Ionic liquids are thermally stable salts and possess strong properties at room temperature, which is why they are preferred as electrolytes for super capacitors. With unique physicochemical properties such as, high thermal stability, electrochemical stability and negligible vapor pressure, ionic liquids are suitable for electrochemical capacitors. On
If you have every wondered what man made nano crystals, then they are officially called as quantum dots. These dots basically are semiconductors of nano technology and they pairs of electrons, semiconductors and valence holes, all in different directions. The combination of various elements is due to the potentiality of electrostatic feature, availability of semiconductor, and availability of semiconductor interface, and even combination of all these.
The dots are known to have separate energy spectrums. Each dot includes tiny number of conduction electrons, excitons which provide electric charges. The smallest quantum dots usually range from 2 nm to 10 nm, they include 10 or 50 atoms in the diameter while about 100 to 100 thousand atoms in one volume.
If the dots are assembled properly they range from 10 to 50 nm of size. These are made from lithographic electrodes or through gases which have dimension more than 100nm. In about 10nm diameter, one can accommodate 3 million dots.
Manufacturers buy quantum dots for LCD TV? See how
The very first things one needs to understand is that the QD television is the advanced version of LED lit TVs. Though the image is still created on the LCD screen, but what makes the resultant
