Nanotechnology, as a whole is still an emerging area with the need to make progress in both scientific and technological terms before enormous commercialization of products may occur. Nanotechnology is the science of manipulating and characterizing matter at the atomic and molecular level (at the sub 100 nm level). It is one of the most exciting fields of science, involving a multitude of science and engineering disciplines, with widespread applications in electronics, chemical industry advanced materials, medicine, IT. Greek prefix nano (dwarf) refers to dimensions which are one hundredth smaller than current components in micrometer range. Figuratively a nano element compares to a football like to football to the size of earth. Nanotechnology is the ability to synthesis, manipulate and characterize matter at the sub 100 nm level. The applications of Nanotechnology are tremendous. This seminars highlights the commercial applications of Nanotechnology in the chemical Industry, includes production of new catalyst, coatings, filtration technologies and other end products as well as the materials upon which these products are based such as dendrimers.
