Hydrogen and Hydrogen-Storage Materials
2007Currently, neutron applications in the field of hydrogen and hydrogen-storagematerials represent a large and promising research area, both from the fundamental and the applied points of view. In this chapter we review some relevant topics from this subject area, including hydrogen bulk properties (concerning both the solid and the liquid phases ...

The hydrogen bond in the solid state.
Angewandte Chemie, 2002The hydrogen bond is the most important of all directional intermolecular interactions. It is operative in determining molecular conformation, molecular aggregation, and the function of a vast number of chemical systems ranging from inorganic to ...

Hydrogen complexes in hydrogenated silicon
Physica B: Condensed Matter, 1991Experimental evidence suggests that H bonds to a fully coordinated Si network in pairs. The total energies and vibration frequencies of various possible pair configurations are calculated using a local density pseudopotential method on supercells. The H * 2 configuration, consisting of a bond centered H and a H located at an adjacent antibonding site,

Hydrogenation of polyaromatics in the presence of hydrogen-hydrogen sulphide system
Fuel, 1989Abstract Thermal production of hydroaromatics by addition of molecular hydrogen to polyaromatics was studied in the presence of hydrogen sulphide or tetralin. The results indicate the importance of wall catalytic effects related to H 2 H 2 S activity during fossil fuel treatment.
