Evaluation of the composition and morphology of a WTi/Si system processed by a picosecond laser
(Korean Inst Metals Materials, Seoul, 2012)
In this work we studied the influence of laser radiation on the composition, structure and morphology of WTi thin films deposited on n-type (100) silicon wafers. The films were deposited by d.c. sputtering from a 70:30 at% ...
Non-noble metal composite cathodes for hydrogen evolution. Part I: The Ni-MoOx coatings electrodeposited from Watt's type bath containing MoO3 powder particles
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
In this work the Ni-MoOx coatings have been prepared and characterized in view of their possible application as electrocatalysts for hydrogen evolution reaction (HER) in alkaline solution. The procedure of deposition of ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solution. Chemical composition, phase composition and morphology effects
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work the hydrogen evolution reaction (HER) onto Ni-Sn alloy coatings deposited at different current densities from the bath containing 0.1 M Sn2+ and 0.1 M Ni2+ ions in the pyrophosphate-glycine solution, was ...
Non-noble metal composite cathodes for hydrogen evolution. Part II: The Ni-MoO2 coatings electrodeposited from nickel chloride-ammonium chloride bath containing MoO2 powder particles
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
In this work the procedure of the deposition of composite Ni-MoO2 coatings onto Ni mesh from the nickel chloride-ammonium chloride electrolyte containing suspended MoO2 powder particles, under simulated industrial deposition ...
Service life test of non-noble metal composite cathodes for hydrogen evolution in sodium hydroxide solution
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work polarization characteristics and "service life" test of the non-noble metal composite coatings Ni-MoOx and Ni-MoO2 for hydrogen evolution reaction (HER) in 32 wt.% NaOH at 90 degrees C were investigated and ...
Phase identification in electrodeposited Ag-Cd alloys by anodic linear sweep voltammetry and X-ray diffraction techniques
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
During electrodeposition of Ag-Cd alloy coatings phenomena of self-organization and formation of spatio-temporal structures can be observed. The difficulties in the determination of the local phase composition in the ...
An attempt to predict the mechanism of Mo-Ni-O powders electrodeposition from the results of their TEM analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The Mo-Ni-O powders were electrodeposited from ammonium sulfate containing electrolytes with different Mo/Ni ion concentration ratios. The phase composition of these powders was investigated using TEM. EDS and XRD analysis. ...
Study of the covalently immobilized amyloglucosidase on macroporous polymer by mathematical modeling of the pH optima
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: A totally new approach has been applied for mathematical modeling of the enzyme activity/pH relationship, for quantification and distribution of enzyme activity in and out of carrier pores. This is a very simple ...
Surface tip-to-base Ca2+ and H+ ionic fluxes are involved in apical growth and graviperception of the Phycomyces stage I sporangiophore
(Springer, New York, 2012)
Net fluxes of Ca2+ and H+ ions were measured non-invasively close to the surface of Phycomyces blakesleeanus sporangiophores stage I using ion-selective vibrating microelectrodes. The measurements were performed on a wild ...
Ti substrate coated with composite Cr-MoO2 coatings as highly selective cathode materials in hypochlorite production
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The aim of this work was to investigate the possibility of preparation of the composite Cr-MoO2 coatings onto steel and titanium substrates as cathode materials with high selective properties which imply the suppression ...
