Many of the metals needed to feed the surging global demand for high-tech products, from smart phones to solar panels, cannot be replaced, leaving some markets vulnerable if resources become scarce, according to a new Yale study.

In a comprehensive analysis, a team of researchers from the Yale School of Forestry & Environmental Studies (F&ES) evaluated how all 62 metals or metalloids on the periodic table of elements are used in consumer products, and the extent to which each of those metals could be replaced if reserves dwindle or supplies become unreliable.

New Technique Creates Stronger, Lightweight Magnesium Alloys

Researchers from North Carolina State University have developed a new technique for creating stronger, lightweight magnesium alloys that have potential structural applications in the automobile and aerospace industries.

Engineers constantly seek strong, lightweight materials for use in cars and planes to improve fuel efficiency. Their goal is to develop structural materials with a high “specific strength,” which is defined as a material’s strength divided by its density. In other words, specific strength measures how much load it can carry per unit of weight. (more…)
