The properties of electroactive ruthenium oxide coatings supported by titanium-based ternary carbides
(Elsevier, 2007)
Electroactive oxide coatings on titanium, known in industrial chlorine production as dimensionally stable anodes (DSA), are of limited service life owing to the dissolution of active oxide, but also due to low corrosion ...
Morphology and growth of electrodeposited silver powder particles
(Elsevier, 2007)
The effect of overpotential pulsing and periodic current reversal on the morphology of silver powders was investigated using a scanning electron microscope (SEM). It is shown that the profile of pulses or current reversal ...
Natural and Modified (1→3)-β-D-Glucans in Health Promotion and Disease Alleviation
(England : Taylor & Francis LTD, 2005)
A number of polysaccharides with β-glycosidic linkage are
widespread in nature in a variety of sources. All have a common structure
and the (1→3)-β-D-glucan backbone is essential. They have attracted attention
over the ...
The Effect of Some parameters of Electrolysis on Apparent Density of Electrolytic Copper Powder in Galvanostatic Deposition
(Switzerland : Trans Tech Publications Ltd, 2000)
The investigation on some properties of electrochemically deposited copper powders from copper sulphate - sulfuric acid has been performed. Relations between conditions of electrolysis of powder storage, apparent density ...
Diagnostic of silicon piezoresistive pressure sensors by low frequency noise measurements
(Sensors and Actuators, A: Physical, 2008)
Low frequency noise measurements can be used as a tool in diagnostics of silicon diaphragm-based piezoresistive pressure sensors after the sensor encapsulation and oil filling process are finished. We measured noise in ...
The influence of zinc surface pretreatment on the adhesion of epoxy coating electrodeposited on hot-dip galvanized steel
(Elsevier, 2007)
The adhesion and electrochemical properties of epoxy coatings electrodeposited on hot-dip galvanized steel with and without passive films were investigated during exposure to 3% NaCl. The passive films were formed in hot ...
Petroleum Pollutant Degradation by Surface Water Microorganisms
(Springer-Verlag GmbH Germany, 2006)
It is well known that the composition of petroleum or some of its processing products changes in the environment mostly under the influence of microorganisms. A series of experiments was conducted in order to define the ...
Metal sorption on macroporous poly(GMA-co-EGDMA) modified with ethylene diamine
(Elsevier, 2004)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate),
poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and
modified ...
Characterization and methanol electrooxidation studies of Pt(111)/Os surfaces prepared by spontaneous deposition
(American Chemical Society (ACS), 2006)
Catalytic activity of the Pt(111)/Os surface toward methanol electrooxidation was optimized by exploring a wide range of Os coverage. Various methods of surface analyses were used, including electroanalytical, STM, and XPS ...
Assessment of heavy metal pollutants accumulation in the Tisza river sediments
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
In this study we have worked on the evaluation of heavy metal contamination in the sediments taken from the Tisza River and its tributaries, and thereby used the sequential extraction method, geochemical normalization, the ...
