Characterization of copper powder particles obtained by electrodeposition as function of different current densities
(Journal of Applied Electrochemistry, 2009)
Technological properties of powders depend on their granulometry and morphology. Very often one method is inadequate for characterization of powder particles. This article studied different methods intended for clear ...
Decorated Ru/Au(111) and Os/Au(111) surfaces: An in situ STM and electrochemistry study
(Russia : Maik Nauka-Interperiodica Publishing, 2006)
The structure and reactivity of bimetallic electrodes obtained by spontaneous deposition of Ru and Os on Au(111) single-crystal surfaces are studied. In situ electrochemical STM and cyclic voltammetry are used to characterize ...
Are Chelate Rings Aromatic? Calculations of Magnetic Properties of Acetylacetonato and o-Benzoquinonediimine Chelate Rings
(American Chemical Society (ACS), 2007)
The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was
investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were ...
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 ...
The kinetics of ethanol adsorption from the aqueous phase onto zeolite NaZSM-5
(Springer, New York, 2008)
The kinetics of the isothermal adsorption of ethanol from an aqueous solution onto a hydrophobic zeolite of the NaZSM-5 type in the temperature range 298-333 K was investigated. Specific shape parameters of the adsorption ...
Parallel alignment of water and aryl rings-crystallographic and theoretical evidence for the interaction
(Royal Soc Chemistry, Cambridge, 2008)
Analysis of crystal structures from the Cambridge Structural Database (CSD) that involve close contact between water and aryl rings revealed the existance of conformations where the water molecule or one of its O-H bonds ...
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 effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
Impact of carboxymethylcellulose on morphology and antibiotic production by Streptomyces hygroscopicus
(Current Microbiology, 2008)
A chemically defined media consisting of carboxymethylcellulose (CMC) was developed to maximize the production of antibiotics, hexaene H-85 and azalomycine, by Streptomyces hygroscopicus CH-7. The production of antibiotics ...
Kinetics of the Formation of Poly(methyldecylsiloxane) by Hydrosilylation of Poly(methylhydrosiloxane) and 1-Decene
(Switzerland : Trans Tech Publications LTD, 2007)
Poly(methylhydrosiloxane) [PMHS], prepared by siloxane equilibration reaction, was used for the hydrosilylation with 1-decene to obtain poly(methyldecylsiloxane) [PMDS]. Pt(0)-1,3-divinyltetramethyldisiloxane complex was ...
