Theory lends transparency to how glass breaks

Over time, when a metallic glass is put under stress, its atoms will shift, slide and ultimately form bands that leave the material more prone to breaking. Rice University scientists have developed new computational methods ...

Trace metal recombination centers kill LED efficiency

Using cutting-edge first-principles calculations, researchers at the University of California, Santa Barbara (UCSB) have demonstrated the mechanism by which transition metal impurities - iron in particular - can act as nonradiative ...

Scientists develop one-step process for making precursors

A one-step solution to make nitrogen-laden molecular precursors for the preparation of drugs and other bioactive molecules has been discovered by researchers at Rice University, the University of Texas Southwestern Medical ...

New method developed for producing some metals

The MIT researchers were trying to develop a new battery, but it didn't work out that way. Instead, thanks to an unexpected finding in their lab tests, what they discovered was a whole new way of producing the metal antimony—and ...

LiH mediates low-temperature ammonia synthesis

Nearly half of the world's population is fed by industrial N2 fixation, i. e., the Harbor-Bosch process. Although exergonic in nature, NH3 synthesis from N2 and H2 catalyzed by the fused Fe has to be conducted at elevated ...

High efficient solar water heating achieved with nanoparticles

A research team in Japan discovered through numerical calculations that nanoparticles of transition metal nitrides and carbides absorb sunlight very efficiently, and confirmed experimentally that nitride nanoparticles, when ...

New path forward for next-generation lithium-ion batteries

In the quest for a radically better lithium-ion battery, a promising direction is the so-called "lithium-rich" cathode, in which the cathode contains a higher proportion of lithium than normal. While it has the potential ...
