The mutual relation of decisive characteristics of electrolytic copper powder and effect of deposition conditions on them
(Nova Science Publishers, Inc., 2008)
The papers dealing with the effects of electrodeposition conditions on the decisive characteristics of electrolytic copper powder and their mutual relations are reviewed, and a semiquantitative theory based on them is ...
Antioxidant properties of grape seed extract on human lymphocyte oxidative defence
(Georg Thieme Verlag Kg, Stuttgart, 2008)
The distribution of polyphenolic compounds in a grape (Vitis vinifera) seed extract (GSE) was determined using LC/ESI-TOF MS, HPLC/DAD, and C-13-NMR. The 17 identified compounds comprised gallic and protocatechuic acid, ...
The contributions of high- and low altitude emission sources to the near ground concentrations of air pollutants
(Elsevier Science Inc, New York, 2008)
The scale of transport through the atmosphere depends on the effective height of an emission source, the meteorological conditions and the physico-chemical characteristics of the pollutants. Atmospheric surface temperature ...
Multipurpose MEMS thermal sensor based on thermopiles
(Elsevier Science Sa, Lausanne, 2008)
This paper presents design, fabrication and experimental results of multipurpose thermopile based sensor which is compatible with technological processes already developed at IHTM-IMTM for fabrication of pressure sensors. ...
Synthesis and characterization of acid-activated Serbian smectite clays obtained by statistically designed experiments
(Elsevier Science Sa, Lausanne, 2008)
Statistically designed experiments were done to study the recovery of Mg content from natural smectite clays from Serbia by hydrochloric acid leaching. The effects of relevant factors, such as temperature, leaching time, ...
Mixed tetraoxanes containing the acetone subunit as antimalarials
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Eleven new tetraoxanes possessing cholic acid-derived carrier and isopropylidene moiety were synthesized and were tested in vitro and in vivo. In vitro screening revealed that nine of them were more potent against CQ-resistant ...
Characterization of platinum deposited on carbon hollow fibers / carbon cryogel composites
(Journal of Optoelectronics and Advanced Materials, 2008)
Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself ...
The inhibiting effect of cobalt(III)-cyclam complexes with substituted β-diketones on iron corrosion in perchlorate solution
(Journal of Solid State Electrochemistry, 2008)
The inhibiting effect of cobalt(III) complexes with macrocyclic ligand cyclam (1,4,8,11-tetraazacyclotetradecane) and β-diketonato ligands have been investigated on iron corrosion in 0.1 M HClO 4 by potentiodynamic, linear ...
Determination of glass temperature of polymers by inverse gas chromatography
(Elsevier, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
