Reflectometry studies of the mechanism of formation of mesoporous silicate fi...
Surfactant-silica self-assembly processes have been extensively studied since the discovery of M41S mesoporous materials in 1992. Mesoporous silicate films can be grown from... -
High-pressure and variable-temperature studies of RDX
Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
Hydrogen from ammonia using lithium imide metal nitride composites
Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to... -
