Effect of hydrogenation on the optical and structural properties of GaAs thin films prepared by rf-magnetron sputtering
(Elsevier B.V., 2005-08-01)
We have utilized infra-red and optical absorption measurements, grazing incidence X-ray diffraction (GIXRD) and extended X-ray absorption fine structure (EXAFS) measurements to investigate the influence of hydrogenation ...
Hydrogen production utilizing glycerol from renewable feedstocks-The case of Brazil
(Pergamon-Elsevier B.V. Ltd, 2011-05-01)
Various reports concerning catalytic reaction of glycerol for hydrogen production is available. However, economic analyses of this activity are not found yet. The objective of this work is to evaluate the process of hydrogen ...
Breath hydrogen test in the diagnosis of environmental enteropathy in children living in an urban slum
(Springer, 2007-05-01)
The aim of this study was to evaluate the breath hydrogen test in the diagnosis of small intestine bacterial overgrowth associated with asymptomatic environmental enteropathy in children living in an urban slum. Fifty ...
Graphene to fluorographene and fluorographane: A theoretical study
(2013-01-25)
We report here a fully reactive molecular dynamics study on the structural and dynamical aspects of the fluorination of graphene membranes (fluorographene). Our results show that fluorination tends to produce defective ...
The hydrogen evolution reaction on codeposited Ni-hydrogen storage intermetallic particles in alkaline medium
(Elsevier B.V., 2000-11-01)
The hydrogen evolution reaction (HER) was studied on Ni-LaNi5 and Ni-MmNi(3.4)Co(0.8)Al(0.8) electrode materials in 1 mol dm(-3) NaOH solution. The steady-state polarization curves and electrochemical impedance spectroscopy ...
BOUND HYDROGENIC STATES IN A MAGNETIC FIELD: A FINITE-DIFFERENCE APPROACH
(World Scientific Publ Co Pte Ltd, 2009-05-20)
A finite-difference scheme is used to calculate bound electronic states of an electron in a hydrogen atom subject to a magnetic field. The numerical results are in good agreement with exact results, in the absence of the ...
Electrocatalysis of oxidation of hydrogen on platinum ordered intermetallic phases: Kinetic and mechanistic studies
(Elsevier B.V., 2006-11-08)
An experimentally based kinetic and mechanistic study of the hydrogen oxidation reaction (HOR) on platinum and platinum ordered intermetallic materials in acid medium is presented. RDE kinetic data were re-evaluated and ...
Hydrogen bonding donation of N-methylformamide with dimethylsulfoxide and water
(2013-04-05)
20% N-methylformamide (NMF) mixtures with water and with dimethylsulfoxide (DMSO) have been studied. A comparison between the hydrogen bonding (H-bond) donation of N-methylformamide with both solvents in the mixtures is ...
ONIOM study of dissociated hydrogen and water on ZnO surface
(Wiley-Blackwell, 2012-10-05)
ONIOM calculations using CCSD theory have been performed to study the dissociation of hydrogen and water molecules on ZnO surface. Three different cluster models were used to study the influence of ONIOM layer size at the ...
Hydrogen oxidation on ordered intermetallic electrodes covered with CO
(Elsevier B.V., 2008-01-10)
This describes an experimental evaluation of the electrocatalytic activity of the hydrogen oxidation reaction on electrodes of platinum and the ordered intermetallic phases PtSb and PtSn, on which CO has previously been ...
