The article describes the use of neutron scattering methods (including powder diffraction, vibrational and rotational spectroscopy, and quasi-elastic scattering) to enhance our understanding of the performance (or lack of performance) of novel storage and ...
We investigate the jamming transition observed in vibrated granular systems composed of millimeter size glass beads. When a granular system is submitted to vibrations with decreasing intensity, it evolves in a way similar to glass-forming liquids: from a l ...

A combined DFT/vibrational spectroscopy approach is used to determine the interactions of the 1,3-dimethylimidazolium ([Mmim]+) and 1-ethyl-3-methylimidazolium ([Emim]+) cations and [BF4]- anions with each other in the liquid state and with Pd nanoparticle ...
In this thesis, I describe the design and first applications of a new molecular-beam/surface-science ultra-high vacuum apparatus. The new machine combines rovibrational state-selective infrared pumping of gas-phase reactants with reflection absorption infr ...
We summarize here our experimental studies of the high rovibrational energy levels of water. The use of double-resonance vibrational overtone excitation followed by energy-selective photofragmentation and laser-induced fluorescence detection of OH fragment ...
The decomposition pathway is crucial for the applicability of LiBH 4 as a hydrogen storage material. We discuss and compare the different decomposition pathways of LiBH 4 according to the thermodynamic parameters and show the experimental ways to realize t ...
The hydrogen absorption of sodium intercalated fullerenes (Na xC60) was determined and compared to pure fullerenes (C60). Up to 3.5 mass% hydrogen can reversibly be absorbed in Na xC60 at 200 °C and a hydrogen pressure of 200 bar. The absorbed amount of hy ...
The decomposition pathway is crucial for the applicability of LiBH 4 as a hydrogen storage material. We discuss and compare the different decomposition pathways of LiBH 4 according to the thermodynamic parameters and show the experimental ways to realize t ...
The hydrogen storage properties of Fe2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) and an oxidized analog, Fe2(O2)(dobdc), have been examd. using several complementary techniques, including low-pressure gas adsorption, neutron powder diffractio ...
The dynamics and bonding of the complex hydrides LiBH4 and LiAlH4 have been investigated by vibrational spectroscopy. The combination of infrared, Raman, and inelastic neutron scattering (INS) spectroscopies on hydrided and deuterided samples reveals a com ...
