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 ...
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 ...
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 ...
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 ...
CO2 looping cycles with CaO-based sorbent pretreated in CO2 at high temperature
(Chemical Engineering Science, 2009)
In this study, pretreatment of CaO-based sorbent in a CO2 atmosphere at high temperature is investigated for its effect on CO2 capture. Three limestones from three widely different geographical locations are used for the ...
Electrodeposition of Ni, Co and Ni–Co alloy powders
(Elsevier, 2006)
In this paper the polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium sulfate containing supporting electrolyte are investigated as a function of Ni ...
SO2 Retention by CaO-based sorbent spent in CO2 looping cycles
(American Chemical Society (ACS), 2009)
CaO-based looping cycles are promising processes for CO2 capture from both syngas and flue gas. The technology is based on cyclical carbonation of CaO and regeneration of CaCO3 in a dual fluidized-bed reactor to produce a ...
