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.

Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, as they provide significant weight-savings while maintaining comparable mechanical properties. Gamma titanium aluminide alloys and an appropriate fiber could offer an improved TMC for use in intermediate temperature applications (400-800°C). The purpose of this investigation is aimed at evaluating the potential of a gamma titanium aluminide alloy with nominal co ....etc

CHAPTER 1
Introduction
1.1 Background
Economic reformation and industrial liberalization by Indian government have attracted varied national and multinational companies to invest on major industries like power plant, petroleum refineries, fertilizers and petro-chemicals and metal industries. Most of these industries are located very close to the sea due to a variety of reasons like convenience in transporting raw materials, availability of seawater for desalination, cooling tower and disposal of trade effluents. Both central and sta ....etc

This seminar report titled Noise Pollution and Control in Chemical Industries deals with the various sources of noise in an industry. It also highlights the hazards that noise causes on man and environment. The report also commets on some measures which can be implemented in noise causing industries to control the noise to an acceptable level. Noise and industry always goes together and every industry is a source of noise. The increased speed to achieve greater productivity, higher velocity of the process stream, vibration etc. are the main cau ....etc
