| The cornerstone of ultrahigh-temperature ceramics is a small group of diboride and carbide ceramic-matrix composites including ZrB2/SiC, HfB2/SiC and ZrB2/SiC/C. They have a unique set of material properties including unusually high thermal conductivity, good thermal shock resistance, and modest thermal expansion coefficients that make them particularly well suited for sharp-body applications in hypersonic flows.
|
| Magnetic composite materials typically consist of a matrix and a dispersed, fibrous or continuous second phase. The second phase may reinforce (strengthen or stiffen), alter electrical or magnetic properties or enhance wear or erosion resistance of adhesives.
|
| Enzymes are the natural solution to industrial problems. Industrial enzymes are those catalysts used on large production-oriented scales to aid the reactions of mass quantities of chemicals.
|
| Scientists at the Weizmann Institute of Science in Israel have produced a new type of nanotube made of gold or silver, which are produced at room temperature and do not have the mechanical strength of the more common carbon nanotubes.
|
| Scientists at JILA at Boulder (CU-Boulder) report the first observation of a Fermionic Condensate formed from pairs of atoms in a gas, a long-sought and novel form of matter.
|
| Renewed economic growth, albeit slow for industrial R&D, and strong U.S. federal funding for defense R&D will be the primary drivers for improved U.S. research & development spending and performance in 2004.
|
| The production of new materials has traditionally been done by experimentation, followed by painstaking characterization to determine the materials' properties.
|
| Intel scientists say that they have made silicon chips that can switch light like electricity, blurring the line between computing and communications and presenting a vision of the digital future that will allow computers themselves to span cities or even the entire globe.
|
| The proposed Free Trade Area of the Americas (FTAA) can be thought of as a huge expansion of the North American Free Trade Agreement (NAFTA). Experts are grappling with how it may help -or hamper- U.S. metal industry competitors.
