Hydrogen has long been recognized as an important energy material and component in energy systems. As such, measuring and understanding its properties over a broad range of conditions is of fundamental interest. New work published in Physical Review Letters shows that hydrogen transforms to a dark fluid at high pressures and temperatures...

Mesoporous and microporous adsorbents play critical roles in gas storage and separation applications. A predictive understanding of high-pressure physisorption on a variety of adsorbents would facilitate the further development of tailored adsorbents and adsorption analysis. Prior attempts at developing a predictive understanding,...

The sodium counterpart to LiFePO4 has recently attracted attention as a potentially promising cathode material. Sodium is one of the major elements in the Earth’s crust and is both environmentally benign and affordable. As a result, the development of sodium analogues to lithium cathode materials is appealing, especially for large energy...

A special issue of the Journal of Organic Chemistry has been dedicated to the 50th anniversary of the discovery of the role of orbital symmetry in the control of organic cycloaddition reactions. The principles underlying the conservation of orbital symmetry and the consequences for understanding the mechanisms of such reactions have...

EFree scientists from Carnegie have discovered a new transition metal pernitride, TiN2, which is ultraincompressible (bulk modulus ~360-385 GPa), and potentially a superhard material. Using a laser-heated diamond anvil cell, titanium nitride (TiN) and nitrogen (N2) were compressed to 73 GPa and heated to 2400 K. At these extreme...
