Chameleon crystals could make active camouflage possible

ANN ARBOR — The ability to control crystals with light and chemistry could lead to chameleon-style color-changing camouflage for vehicle bodies and other surfaces.

University of Michigan researchers discovered a template-free method for growing shaped crystals that allows for changeable structures that could appear as different colors and patterns. (more…)

Cosmochemist discovers potential solution to meteorite mystery

Chondrules may have formed from high-pressure collisions in early solar system

At issue is how numerous small, glassy spherules had become embedded within specimens of the largest class of meteorites—the chondrites. British mineralogist Henry Sorby first described these spherules, called chondrules, in 1877. Sorby suggested that they might be “droplets of fiery rain” which somehow condensed out of the cloud of gas and dust that formed the solar system 4.5 billion years ago. (more…)

Under Pressure: Germanium

Washington, D.C. — Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics.

New research conducted by Xiao-Jia Chen, Viktor Struzhkin, and Ho-kwang (Dave) Mao from Geophysical Laboratory at Carnegie Institution for Science, along with collaborators from China, reveals details of the element’s transitions under pressure. Their results show extraordinary agreement with the predictions of modern condensed matter theory. (more…)
