Nanosilica/PMMA composites obtained by the modification of silica nanoparticles in a supercritical carbon dioxide-ethanol mixture
(Springer, New York, 2009)
Nanosilica/poly(methyl methacrylate) (PMMA) composites are used to improve the mechanical properties of neat PMMA polymer. In order to obtain superior mechanical properties, it is essential to achieve good bonding between ...
Electrocatalytic behaviour of MoPt3 intermetallic phase for hydrogen evolution in acid solution
(Ecole Polytechnique de Montreal, 2004)
Metallurgicaly prepared MoPt3 intermetallic compound has been investigated as electrocatalyst for the cathodic evolution of hydrogen (HER) in 0.5 mol dm-3 HClO4 solution at 298 K. The HER on activated and non-activated ...
Methanol oxidation on an ink type electrode using Pt supported on high area carbons
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
Methanol oxidation was investigated on the following Pt catalysts: bare Pt electrode, Pt covered by nafion (R) film, and pt catalysts supported on high area carbons in the form of an ink. The reaction was carried out using ...
Magneli phase titanium oxides as catalyst support - Electrochemical behavior of Ebonex/Pt catalysts
(Journal of New Materials for Electrochemical Systems, 2006)
The impregnation method has been applied to synthesize platinum nanoparticles on Magneli phase titanium oxide powder (Ebonex). Surface area of the Ebonex support was determined by BET technique. Distribution and morphology ...

Experimental study of zinc morphology in alkaline electrolyte at low direct and pulsating overpotentials
(Elsevier Sequoia SA, 2000)
A possible mechanism of the formation of spongy zinc electrodeposits is considered. The confirmation of the proposed semiquantitative mathematical model is performed in zinc electrodeposition onto copper wire from a 0.1 M ...
Radioactive reliability of programmable memories
(Japanese Journal of Applied Physics Part 1-Regular Papers Short Notes and Review Papers, 2001)
In this study, we examine the reliability of erasable programmable read only memory (EPROM) and electrically erasable programmable read only memory (EEPROM) components under the influence of gamma radiation. This problem ...
HPLC behavior and hydrophobic parameters of some anilides
(Springer Heidelberg, Heidelberg, 2001)
The chromatographic behavior of para substituted anilides of 2,2-dimethylpropanoic, benzoic and alpha -phenyl acetic acid has been studied by reversed-phase high performance liquid chromatography HPLC was performed on a ...
Nanostructured sodium niobate obtained by glass crystallization
(Elsevier Science Sa, Lausanne, 2004)
The subject of this work was to obtain nanostructured sodium niobate crystals by a controlled crystallization method from glasses. The glass samples of the composition within the system NaNbO3-SiO2-Al2O3 were prepared by ...
Influence of an antimicrobial treatment on the strength properties of polyamide/elastane weft-knitted fabric
(Wiley, Hoboken, 2007)
Polyamide/elastane weft-knitted fabric, as a suitable compression material, was treated with gentamicin sulfate and a natural antimicrobial preparation of the autochthonous essential oil of Picea abies. The antimicrobial ...
