NANOTECHNOLOGY

INTRODUCTION: Everything we see around us is made of atoms, the tiny elemental building blocks of matter.

Biotechnology was the first nanotechnology, and it has a long way yet to go

Carbon nanotubes,for example, are expected to produce fibers 100 times stronger than steel at only 1/6th the weight.

NTR (NANO TECHNOLOGY REVOLUTION): - Long-term nano science and engineering research that will lead to fundamental understanding and to discoveries of novel phenomena, processes and tools for nanotechnology. - Synthesis and processing “by design” of engineered, nanometer-size, material building blocks and system components, fully exploiting molecular self-assembly concepts - Nanodevice concepts including system architecture research to best exploit nano-derived properties in operational systems, and combining building-up of molecular structures with ultra miniaturization - Application of nanostructured materials and systems to manufacturing, power systems, energy, environment, national security, and health. Areas of interest include advanced dispersions, catalysts, separation methods, and consolidated nanostructures, as well as increase the pace of knowledge and technology transfer; - Educate and train a new generation of skilled workers in the multidisciplinary perspectives necessary for rapid progress in nanotechnology.

Potential for NTR impact is forcing:

- Nano science and engineering knowledge is exploding worldwide because of thavailability of new investigative tools; maturity in the biology, chemistry engineering, materials and physics disciplines, and interdisciplinary synergism

- Nanoscience is an opportunity to energize the interdisciplinary connections between biology, chemistry, engineering, materials, mathematics, and physics in education. It will give birth to new fields that are only envisioned at this moment;

NANOTECHNOLOGY – A REVOLUTION IN THE MAKING: 1. Nanotechnology Definition Nanotechnology is concerned with materials and systems whose structures and components exhibit novel and significantly improved physical, chemical and biological properties, phenomena and processes because of their small nano scale size. Structural features in the range of about 10-9 to 10-7 m (1 to 100 nanometers) determine important changes as compared to the behavior of isolated molecules (1 nanometer) or of bulk materials

Revolution in the Making: DRIVING FORCES

It was not until the 1980s that miniaturization of instruments actually surfaced in developments force micro scopes and near field microscopes. These instrument classes exploited micro fabrication technology to enable nanometer resolution a wide variety of the “eyes” and “fingers” required for nanostructure measurement and manipulation. In a parallel development, augmented computational capability now enables sophisticated computer simulations of nano srtuctures
