Nanografi Nanotechnology

Nanoparticles/Nanopowder  start to be very popular over the last decade. What are these tiny materials? A nanoparticle/nanopowder (nanocluster or nanocrystal) means that a microscopic particle. It was at least one dimension less than 100 nm. Several area such as biomedical, optical, and electronic fields use these materials in wide variety of potential applications. Current several scientific research mainly concentrated on these materials. Since their size are nearly nanoscale and as the percentage of atoms at the surface of a material becomes significant the properties of materials change. Moreover, when it was compared with the bulk material,  nanoparticle/nanopowder  exhibits a number of special properties. Another key property is that nanoparticles/nanopowder have a very high surface area to volume ratio.Thanks to this property, nanoparticles/nanopowder have a tremendous driving force for diffusion ability, especially at elevated temperatures.
