Nano particle and its properties
In nanotechnology, a nano particle or say nano powder or nano cluster or nano crystal is a small object or say, a microscopic particle that has dimension of 100 nanometers or less in size. And it is being used in the manufacture of scratchproof eyeglasses, crack- resistant paints, anti-graffiti coatings for walls, transparent sunscreens, stain-repellent fabrics, self-cleaning windows and ceramic coatings for solar cells etc. Nano particles can contribute to stronger, lighter, cleaner and "smarter" surfaces and systems. And these days companies have been looking at how they may be applied it for their own purposes, thus number of companies (like ssnano.com) supplying industrial quantities of nano particles for different needs.
For your brief knowledge – Nano particle is currently an area of intense scientific research, due to its wide variety of potential applications in biomedical, optical, and electronic fields. And these nowadays are the great scientific interest as these are effectively a bridge between bulk materials and atomic or molecular structures.
Though bulk materials have constant physical properties but it is not so useful regarding size. As a definition says about it – its "Novel properties" differentiate nano particles from the bulk material typically develop at a critical length scale of under 100nm. So these are entirely dependent on the fact that at the nano-scale and the physics of nano particles with its properties are different from the properties of the bulk material.
Well, besides of that, there is a strict dividing line between nano particles and non-nanoparticles at which these materials display different properties to the bulk material that is material dependant and can certainly be claimed for many materials much larger in size than 100nm. Thus this sort of nano material has led to the extension of the idea of nano materials being considered as such if any one of their structural features is on a scale of less than 100nm, that cause their properties to be different from that of the bulk material.
Well, many of these nano powder or say nano materials are made directly as dry powders and it is a common myth that these powders will stay in the same state when stored. In fact, they will rapidly aggregate through a solid bridging mechanism in as little as a few seconds. Whether these aggregates are detrimental will depend entirely on the application of the nano powder.
As said earlier, nano powder applications have been limited by the availability of sufficient quantities of material, but due to the global market competition nano powder or say, nano particle becomes a competitive edge in product performance. So if you are wondering to purchase this high quality nano materials then head on to ssnano.com to find the best for your need.
