Scientists have used pressure with a twisting shear to permanently deform silicon, an important material for electronics. The resulting changes in silicon's microstructure produce material phases that ...

By stacking custom-designed silver nanoparticles like nanoscale LEGO bricks, scientists stabilized a mysterious crystal phase that had never been observed before. The material not only solves a ...

High-pressure studies of silicon and germanium reveal a rich landscape of structural rearrangements that profoundly alter their electronic, optical and mechanical properties. Under compression, the ...

AMES, Iowa – When Valery Levitas left Europe in 1999, he packed up a rotational diamond anvil cell and brought it to the United States. He and the researchers in his group are still using a ...
