Hydrogen oxidation on ordered intermetallic phases of platinum and tin - A combined experimental and theoretical study
(2013-03-15)
Hydrogen oxidation on the surfaces of the intermetallic compounds Pt 3Sn, PtSn and PtSn2 has been studied by the rotating disc electrode technique. Pt3Sn and PtSn were found to be good catalysts, about as good as Pt, while ...
Changes on iron electrode surface during hydrogen permeation in borate buffer solution
(Pergamon-Elsevier B.V. Ltd, 2008-04-01)
Hydrogen interaction with oxide films grown on iron electrodes at open circuit potential (E-oc) and in the passive region (+0.30 V-ECS) was studied by chronopotentiometry, chronoamperometry and electrochemical impedance ...
Hydrogen influence on gallium arsenide thin films prepared by rf-magnetron sputtering technique
(Sociedade Brasileira Fisica, 2006-09-01)
We investigate the effect of the hydrogen intentional incorporation on the structural properties of the amorphous gallium arsenide prepared by rf-magnetron sputtering technique. The properties of the non-hydrogenated films ...
Structure and weak hydrogen bonds in liquid acetaldehyde
(2004-08-30)
Monte Carlo simulations have been performed to investigate the structure and hydrogen bonds formation in liquid acetaldehyde. An all atom model for the acetaldehyde have been optimized in the present work. Theoretical ...
Electrode surface modifications improve cathode hydrogen production and anode capacity in Ni-MH batteries
(Elsevier B.V., 2006-02-01)
This paper reports results from electrochemical evaluations of electrodes used as cathodes for a hydrogen evolution reaction and anodes in Ni-MH batteries that had been surface-modified by micro-encapsulation, co-deposition ...
Lichen metabolites modulate hydrogen peroxide and nitric oxide in mouse macrophages
(2009-11-20)
The activities of perlatolic acid (1), atranorin (2), and lecanoric acid (3) and their derivatives, such as orsellinates and β-methyl orsellinates obtained by alcoholysis, were assessed for stimulation of the release of ...
Prediction via neural networks of the residual hydrogen peroxide used in photo-fenton processes for effluent treatment
(Wiley-Blackwell, 2007-08-01)
This communication proposes the use of neural networks in the prediction of residual concentrations of hydrogen peroxide from the treatment of effluents through Advanced Oxidative Processes (AOP's), in particular, the ...
Correlation between hydrogen storage properties and textures induced in magnesium through ECAP and cold rolling
(Elsevier B.V., 2014-03-06)
It is feasible to obtain a significant enhancement of the hydrogen storage capability in magnesium by selecting an appropriate sequence of mechanical processing. the Mg metal may be produced with different textures which ...
Differential cross sections for elastic and inelastic positronium-hydrogen-atom scattering
(American Physical Soc, 2014)
Hydrogen production by biogas steam reforming: A technical, economic and ecological analysis
(2013-08-28)
Fuel cells are electrochemical energy conversion devices that convert fuel and oxidant electrochemically into electrical energy, water and heat. Compared to traditional electricity generation technologies that use combustion ...
