Boron Carbide exhibits a number of important material properties, among them extreme hardness approaching that of diamond, and a very high melting point. However, it is the low density of the material that makes it attractive for applications requiring high mechanical strength and light weight. Its properties are due to the unique...

A recent advance toward the goal of increasing achievable static pressures beyond the mechanical limits imposed by the diamond anvil cell has been in the development of “two-stage” diamond anvils. Two-stage anvils consist of a small “micro-anvil” with a culet size on the order of 30 microns fixed onto the culet of a larger diamond anvil...

Chemical reactions involving acetonitrile most often occur as the result of activating the C-N triple bond, while the C-H bonds are generally considered inert. Weak intermolecular hydrogen bonds of the N - - H - C type, however are susceptible to modification by applied pressure. Now a group including CDAC Research Scientist Zhenxian Liu...

Understanding the behavior of dense hydrogen remains a major challenge in both condensed matter physics and energy science, and high-pressure experiments and theoretical calculations have uncovered a number of novel phenomena in this fundamental system. Theoretical work by CDAC Research Scientist Ivan Naumov and CDAC Director Russell J....

It has long been recognized that applied pressure can significantly change the conventional patterns of chemical reactivity predicted by the structure of the Periodic Table. At the same time, among thousands of known interactions between elements in the Periodic Table, there remain chemical bonds that are curiously absent. But is high...
