Producing materials by chemical vapor deposition (CVD) has become an important means of synthesis, in which high-energy molecular and atomic species generate a kinetically stable phase trapped in local energy minimum. Single crystal, polycrystalline, and nanocrystalline diamond now can be produced by microwave plasma assisted CVD (MPCVD...

The iron-oxygen system is the most important reference of a rock’s oxidation state. Even as minor components in many petrologic systems, iron oxides can play a critical role in controlling redox equilibria, which in turn affect the speciation of fluid phases, chemical differentiation, melting behavior, and other important physical...

CDAC graduate student Greg Hohensee and his research advisor, CDAC Academic Partner David Cahill at the University of Illinois, have used diamond anvil cell techniques to uncover new physics associated with heat transfer across diamond-metal interfaces. Their paper, published in Nature Communications, illustrated the critical role of...
