A Johns Hopkins materials science and engineering professor is leading a multi-university team of researchers with a mission to expedite the process by which new and important materials are created for use by the U.S. Navy in a variety of applications, from hypersonic vehicles to batteries.
Copper is the metal that is at the heart of the electronics, semiconductor and electro-optics industry. But oxidation and unwanted corrosion on its surface can limit the lifespan and increase the electrical resistance of Cu. Now, a team of researchers led by Prof. Se-Young Jeong from Pusan National University have developed a way to fabricate oxidation-resistant thin films of copper.
When you stretch a material, it normally becomes thinner. Take the case of a rubber elastic band. Most materials behave like this. Yet, a small number of materials can become thicker when they are stretched.
The National Institute for Materials Science (NIMS) has succeeded in developing a new approach to the design of thermoelectric materials by constructing a database of electronic structure parameters correlated with materials’ thermoelectric conversion properties and by a comprehensive analysis of the database.
European scientists say they have made a major breakthrough in their quest to develop practical nuclear fusion—the energy process that powers the stars. As a bonus to the environment, it is carbon free. Courtesy of BBC News.
