Hydrogen and deuterium absorption in LaNixMny

International Journal of Hydrogen Energy, 1986
Abstract Absorption and desorption of H 2 (D 2 ) in LaNi x Mn y alloys of three different compositions: LaNi 4.5 Mn 0.09 , LaNi 5.19 Mn 0.39 and LaNi 6.37 Mn 0.33 were investigated. Pressure-composition isotherms and kinetic curves of corresponding reactions were obtained at 40, 80 and 100°C.

Infrared absorption strength and hydrogen content of hydrogenated amorphous silicon

Physical Review B, 1992
We have used infrared transmission and nuclear-reaction analysis to determine the ir absorption strength of the Si-H wagging and stretching modes in hydrogenated amorphous silicon (a-Si:H). The films were deposited by plasma-assisted chemical vapor deposition and reactive magnetron sputtering.

Hydrogen absorption in vanadium pentoxide

Materials Research Bulletin, 1988
Abstract The paper describes the reactor developed in our laboratory for studying hydrogen absorption characteristics of materials suitable for hydrogen energy storage and H 2 -D 2 separation. Vanadium pentoxide has been chosen for the case study. It is found that platinum activated V 2 O 5 reacts with hydrogen at around 150°C to give H 3 V 2 O 5 .

Hydrogen absorption characteristics in Zr0.2Ho0.8CoFe

Journal of Alloys and Compounds, 1998
Hydrogen absorption studies have been carried out on the Zr0.2Ho0.8CoFe alloy which has the C15 cubic Laves phase structure. The data were collected in the temperature and pressure ranges 27≤T(°C)≤150 and 0.05≤P(bar)≤45 respectively. A maximum hydrogen concentration of 9 hydrogen atoms per formula unit at 43 bar at RT is observed.

FIELD-INDUCED ABSORPTION IN HYDROGEN

Canadian Journal of Physics, 1958
This paper reports an investigation of the fundamental rotation–vibration absorption induced in hydrogen by an electric field. The integrated absorption coefficients of the first four components of the Q branch have been measured for a range of field strengths at densities of 83.9 and 44.6 Amagat. The integrated absorption coefficient of the S(1) line

Absorption of hydrogen in copper

Journal of the Chemical Society, Faraday Transactions, 1995
Reduction of an alumina-supported copper catalyst under the conditions used as standard for the reduction of the Cu/ZnO/Al2O3 methanol-synthesis catalysts produces multilayers of hydrogen in the copper. This absorption of the hydrogen results in a reconstruction of the copper with the effect that only the surface hydrogen may be thermally desorbed ...

Hydrogen absorption in ϵ-Ti3P

Journal of the Less Common Metals, 1986
Abstract The solubility of hydrogen in ϵ-Ti3P was investigated in the range 0.009 ⩽ pH2(bar) ⩽ 1; 935 ⩽ T(K) ⩽ 1175. From the absorption isotherms ΔHH° = −42.2 ± 0.2 kJ mol−1 and a linear dependence of ΔHH on the hydrogen concentration is found. Assuming that at low concentration hydrogen occupies Ti4-coordinated tetrahedral interstitial sites with ...

Hydrogen absorption of nanocrystalline palladium

Journal of Alloys and Compounds, 2002
Abstract Thermodynamic properties of hydrogen in nanocrystalline Pd (Pd-n) were determined by pressure–composition ( P–C ) isotherms. Pd-n was prepared by repeated compression–extrusion cycles in the die cavity of a high speed forging apparatus. It was found that Pd obtained was composed of nano-sized Pd grains, i.e.

Hydrogen absorption by lanthanide silicides

Journal of the Less Common Metals, 1985
Abstract The hydrogen absorption behaviour of Ln5Si3, (Ln ≡ Y, La, Nd, Ho) and related compounds is similar to that of the parent metal. This behaviour has been studied by gravimetric and volumetric methods. Particular attention was paid to the question of how strain in the host compound shifted the α → β phase transition temperature in Ho5Si3Hx ...
