NANOMATERIALS, PROCESS AND APPLICATIONS (Subject Code: 10BG501)

Offered by Department of Bio Technology

The objective of this course is to educate the students about materials, process and applications of

nanotechnology. Nanomaterials are of grain sizes of the order of a billionth of a meter. It is a known fact

that nanomaterial outperform their conventional counterparts because of their superior chemical, physical

and mechanical properties. Particles, complexes, tubes, coatings, active surfaces and devices are being

explored on the nanoscale. Assembly of natures building blocks (e.g. carbon, nucleic acids, lipids andpeptides) along with the combination of different materials (e.g. CdSe/ZnS, Au, Ag, Si(n)OH(n)), light

harvesting dendrimers and thin films) are resulting in newer applications. Since nanomaterials possess

unique chemical, physical and mechanical properties, they can be used for a wide variety of applications

such as next-generation computer chips, kinetic energy penetrators with enhanced lethality, betterinsulation materials, phosphors for high-definition tv, low-cost flat-panel displays, tougher and harder

cutting tools, elimination of pollutants, high energy density batteries, high-power magnets, high-

sensitivity sensors, automobiles, aerospace components, medical implants, ductile etc.
