Functional supramolecular tetrathiafulvalene-based films with mixed valences states [PDF]
, 2016 Tetrathiafulvalene molecules substituted with a carboxylic acid group (TTFCOOH) were bound as redox-active moieties into a poly(4-vinyl pyridine) (P4VP) skeleton through non-covalent interactions (hydrogen bonds). The aspect of the resulting P4VP-TTFCOOH

Role of Additives in LiBH4-MgH2 Reactive Hydride Composite sorption reactions
, 2010 The influence of additives on the reaction kinetics and microstructure refinement in LiBH4–MgH2 composites is investigated in detail. Indications of the rate-limiting processes during the reactions are obtained by comparison of the measured reaction kinetics with simulations with one specific rate-limiting process.

Reactive hydride composites for efficient hydrogen energy storage
, 2016 Solid state chemical storage of hydrogen in metals offers promising advantages over compressed hydrogen gas and condensed liquid hydrogen, especially for mobile applications with respect to safety and energy efficiency. However, no single metal hydride simultaneously satisfies the essential performance criteria for onboard hydrogen storage namely, high

In situ Raman and neutron spectroscopy of complex hydrides [PDF]
The search of suitable hydrides for hydrogen storage can benefit from Raman and neutron spectroscopy, especially when it is possible to exploit these diagnostic techniques in situ, that is, in controlled conditions of gas pressure and temperature.
