Document Summary
Nanotechnology - manipulation of matter on the 1-100 nanometer scale. Nanoscience - fundamental studies of matter on the 1-100 nanometer scale, especially for properties of the matter are different at 1 to 100 nm compared to bulk or atoms. Nanoparticles are used as catalysts instead of bulk metal surfaces. When nanoparticles are used, there is more control of the structure and the size which can fine tune how the nanoparticles work. No agglomeration, improved adhesion, coating of monoliths. As the nanoparticles get larger, this decreases the surface to volume ratio and can really change the properties of the nanoparticles. Intel predicted in 2007 that shrinking silicon integrated circuit technology down to the limit will be done by the year 2015! How to make things on the 1-100 nm scale. Start at the smallest level and then increase the size to make something that they want.
