Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans - Research on a model system
(Elsevier, 2008)
Oil shale is one of the alternative sources of hydrocarbon fuels ("synthetic petroleum") but is characterized by increased sulfur and nitrogen contents, which represent even greater ecological problems in its use compared ...
Investigation of interface and surface energy states in semiconductors by PA method
(European Physical Journal: Special Topics, 2008)
The photoacoustic (PA) signal should generally change with the extent of damage, in the form of surface energy states (SES) or interface energy states (IES). For a mechanically, chemically or particles processed (Ar-plasma ...
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, ...
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 ...
Interrupted-flux deposition: Ni on Ru(0001)
(Elsevier, 2008)
Nickel was deposited on Ru(0001) in a vacuum chamber at a temperature of 295 K. The depositions were performed using both a continuous and an interrupted flux of Ni, up to the same coverage of 0.25 monolayer. The growth ...
Surface resistivity estimation by scanning surface potential microscopy
(AIP Publishing, 2008)
Nickel was sputter deposited on a glass with a thin film thickness of 600 nm under either in an argon atmosphere or under a partial pressure of nitrogen of either 1.3× 10-4 or 4× 10-4 mbar. Atomic force microscopy and ...
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 ...
X-ray analyses, spectroscopic and magnetic properties of [Cu4(succinato)(tpmc)2](ClO4) 6·2C2H5OH·4H2O and [Cu2(C6H5COO)tpmc](ClO4) 3·0.5CH3OH·0.5H2O complexes
(Elsevier, 2008)
[Cu4(succinato)(tpmc)2](ClO4) 6 · 2H2O (tpmc = N,N′,N″,N‴-tetrakis-(2-pyridylmethyl)-1,4,8,11-tetraa zacyclotetradecane, succinato = dianion of succinic acid) has been prepared and characterized by elemental analysis, ...
Optimization of micro/nanooscillator parameters for analysis of transient adsorption processes
(Institute of Electrical and Electronics Engineers Inc., 2008)
We consider optimization of parameters of micro/nanooscillators intended for investigation of adsorptiondesorption (AD) processes, which are fast in comparison with the response rate of the oscillator itself. We consider ...
