Hydrogen self-dynamics in orthorhombic alkaline earth hydrides through incoherent inelastic neutron scattering
(Elsevier Science Sa, 2007-01)
Inelastic neutron scattering patterns from polycrystalline CaH2, SrH2 and BaH2, measured on TOSCA-II spectrometer at low temperature in the energy transfer range 3 meV < E < 500 meV are reported. From the medium-energy ...
HYDRIDE TRANSFER VERSUS ELECTRON-TRANSFER IN THE BAKERS-YEAST REDUCTION OF ALPHA-HALOACETOPHENONES
(Pergamon-elsevier Science LtdOxfordInglaterra, 1993)
Study of MgH2 + NbF5 mixtures: Formation of MgH2−xFx solid solutions and interaction with hydrogen
(Elsevier, 2015-02)
A mixture of MgH2 and (7 mol%) NbF5 has been mechanically milled under Ar atmosphere. The evolution of the materials has been studied by in situ pressure monitoring, XRD, DSC, TG, TPD, SEM, and isothermal hydrogen absorption ...
Formal hydride transfer mechanism for photoreduction of 3-phenylquinoxalin-2-ones by amines. Association of 3-phenylquinoxalin-2-one with aliphatic amines
(AMER CHEMICAL SOC, 2000-11-17)
The photophysical and photochemical behavior of 1-methyl-3-phenylquinoxalin-2-one (MeNQ) and 3-phenylquinoxalin-2-one (HNQ) in the presence of amines is reported. While HNQ fluorescence shows an auxochromic effect and a ...
Designing an Ab2-type alloy (TIZr-CrMNMO) for the hybrid hydrogen storage concept
(Multidisciplinary Digital Publishing Institute, 2020-06)
The hybrid hydrogen storage method consists of the combination of both solid-state metal hydrides and gas hydrogen storage. This method is regarded as a promising trade-off solution between the already developed high-pressure ...
Li 1s core exciton in LiH studied by x-ray Raman scattering spectroscopy
(IOP Publishing, 2019-02)
The Li 1s core excitation spectra in LiH was studied by means of x-ray Raman scattering (XRS) spectroscopy in a wide range of momentum transfers q. The analysis of the near-edge region of the measured spectra in combination ...
New response in electrochemical impedance spectroscopy due to the presence of molybdenum on AB5-type alloys
(Pergamon-Elsevier Science Ltd, 2015-04)
During the present investigation, it was observed that the inclusion of molybdenum in LaNi3.6Co0.7Mn(0.4-x)Al0.3Mox AB5-type alloys produced new responses in the electrochemical impedance spectroscopy (EIS) when they are ...
