Gallium nitride has wear resistance that approaches that of diamond

By April Gocha / November 15, 2016

Researchers at Lehigh University report that in addition to gallium nitride’s checklist of other useful properties, the material has a wear rate that approaches that of diamonds—which could open the material’s foray into even more diverse applications.

Solar energy news roundup: Solar cells go ‘green,’ ultrathin, and power 24/7

By Stephanie Liverani / June 21, 2016

It’s officially summer—and that means more sun-filled days ahead. So it’s only fitting that we round up the latest solar energy research news. This week, solar cells get ‘greener’ and thinner, and a solar power plant in Nevada keeps the energy going 24/7.

Distorted reality: Revolving electron microscopy divulges material’s innermost atomic secrets

By April Gocha / February 17, 2015

Researchers at North Carolina State University have pioneered a new imaging method that is allowing them to peer inside a material’s atomic organization to precisely map the location of distortions, a unique perspective that is allowing them to see how those distortions affect the material’s properties.

Check ’em out: Ultrafast large-amplitude relocation of electronic charge in ionic crystals (pdf) (PNAS, Early Edition) We have demonstrated an ultrafast relocation of charge that is induced by electronic excitation and steered by coherent low-frequency motions of the ionic crystal lattice. Our results reveal the nonequilibrium charge dynamics in ionic materials on their intrinsic length…
