Features

Advanced Materials and the Economy

Progress in materials science and engineering stim ulates the growth of many sectors of the economy. New materials and processes meet the needs of existing industries and give birth to new technology

By Joel P. Clark and Merton C. Flemings

Materials for Information and Communication

From vacuum tubes to transistors to integrated circuits and optical fibers, the dramatic rise in the power of systems that process and transmit information has depended on advances in materials science

By John S. Mayo

Materials for Aerospace

US. goals for su bsonic, supersonic and hypersonic flight and for space exploration call for alloys and composites notable for strength, light weight and resistance to heat

By Morris A. Steinberg

Materials for Ground Transportation

The 40 million cars and trucks produced every year consume a huge quantity of material. Far more of it is now aluminum, plastic or high-strength steel; correspondingly less is ordinary steel or cast iron

By Norman A. Gjostein and W. Dale Compton

Materials for Energy Utilization

The economic well-being of any modern society requires that energy be captured, converted from one form into another and consumed in myriad ways. Each step demands materials with special properties

By Louis A. Girifalco and Richard S. Claassen

Materials for Medicine

New polymers, ceramics, glasses and composites are among the many materials now enabling medical engineers to design innovative, and increasingly biocompatible, replacements for damaged human tissues

By Jonathan J. Rosen and Robert A. Fuller

Electronic and Magnetic Materials

Soon semiconducting chips employed in high-speed logic operations will be imprinted with more than 100,000 transistors, and chips in a computer's memory will store up to 16 million bits of information

By Praveen Chaudhari

Photonic Materials

The advantages of transmitting light signals instead of electrical ones have led to ultrapure glass, semiconductor alloys only a few atoms thick and "nonlinear" materials that are now revolutionizing communications

By J. M. Rowell

Advanced Ceramics

These nonmetallic, nonpolymeric materials are hard, resist heat and chemicals and can be designed to have special electrical properties. Research Focuses on a major shortcoming: a tendency to crack easily

By H. Kent Bowen

Composites

Composition and internal architecture can be varied freely in these hybrid materials in order to match their performance to the most demanding structural roles

By Tsu-Wei Chou, Roy L. McCullough and R. Byron Pipes
