Zeolite-templated carbon (ZTC) materials were synthesized, characterized, and evaluated as potential hydrogen storage materials between 77 and 298 K up to 30 MPa. Successful synthesis of high template fidelity ZTCs was confirmed by X-ray diffraction

Interest in new ultraincompressible hard materials has prompted studies of transition metal diboride solid solutions. We have synthesized pure RuB2 and solid solutions of Os1−xRuxB2. The mechanical properties of these materials are investigated usi

Hardness is measured by indenting, or by scratching, a solid. In general, it is a measure of structural stability which, in turn, is determined by elastic stiffness, plastic resistance, resistance to structure change; all of which vary with chemical

The addition of lithium amide (LiNH2) and ammonium chloride (NH4Cl) to metathesis (exchange) reactions between gallium triiodide (GaI3) and lithium nitride (Li3N) produces crystalline gallium nitride (GaN) in seconds at ambient pressure. A specially

We report that a ternary magnesium nickel boride (MgNi_(2.5)B_2) mixed with LiH and MgH_2 can be hydrogenated reversibly forming LiBH_4 and Mg_2NiH_4 at temperatures below 300 °C. The ternary boride was prepared by sintering a mechanically milled mi

The quest to create superhard materials rarely strays from the use of high-pressure synthetic methods, which typically require gigapascals of applied pressure. We report that rhenium diboride (ReB 2 ), synthesized in bulk quantities via arc-melting u

The need for wear- and scratch-resistant materials drives the quest for new superhard materials. In this work, we apply two design parameters to identify ultra-incompressible, superhard materials-high valence electron density and high bond covalency.

The lattice strain behavior of osmium diboride—a member of a group of third-row transition metal borides associated with hard/superhard behavior—has been studied using radial diffraction in a diamond anvil cell under high pressure and non-hydrost
