Formic acid oxidation on Pt-Au nanoparticles: Relation between the catalyst activity and the poisoning rate
(Elsevier Science Bv, Amsterdam, 2012)
Pt-Au nanoparticles supported on high area carbon were prepared by simultaneous reduction of Au and Pt precursors and by reduction of Pt precursor on already prepared Au nanoparticles. The first method produced a solid ...
Kinetics measurements and in situ Raman spectroscopy of formation of hydrogen-tetrabutylammonium bromide semi-hydrates
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The kinetics of formation of H-2-TBAB semi-clathrate hydrates was studied in this work in order to elucidate their potential for H-2 storage. The influence of pressure (5-16 MPa), TBAB concentration (2.6 mol% and 3.7 mol%) ...
Modelling of non-catalytic biodiesel synthesis under sub and supercritical conditions: The influence of phase distribution
(Elsevier, Amsterdam, 2012)
Biodiesel, a mixture of fatty acid methyl esters, is widely used as renewable bio-based alternative fuel for internal combustion engines. Kinetic model of non-catalytic biodiesel synthesis at elevated temperature and ...
Increase in bioethanol production yield from triticale by simultaneous saccharification and fermentation with application of ultrasound
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: Bioethanol produced from renewable biomass, such as sugar, starch or lignocellulosic materials, is one of the alternative energy resources that is environmentally friendly. Triticale crops have a high yield as ...
Removal of Sulfur Compounds from Mineral Insulating Oils by Extractive Refining with N-Methyl-2-pyrrolidone
(Amer Chemical Soc, Washington, 2012)
Copper sulfide deposits in the insulation systems of power transformers decrease the dielectric properties of the insulation and therefore constitute a significant risk for the operation of power transformers. Disulfides, ...
The effect of grain size on the biocompatibility, cell-materials interface, and mechanical properties of microwave-sintered bioceramics
(Wiley, Hoboken, 2012)
The effect of decreasing the grain size on the biocompatibility, cellmaterial interface, and mechanical properties of microwave-sintered monophase hydroxyapatite bioceramics was investigated in this study. A nanosized ...
Novel glycoside of vanillyl alcohol, 4-hydroxy-3-methoxybenzyl-alpha-d-glucopyranoside: study of enzymatic synthesis, in vitro digestion and antioxidant activity
(Springer, New York, 2012)
Novel glucoside of physiological active vanillyl alcohol was synthesized for the first time using maltase from Saccharomyces cerevisiae as catalyst, and established its structure as 4-hydroxy-3-methoxybenzyl-alpha-d-gluc ...
Study of small chlorine-doped potassium clusters by thermal ionization mass spectrometry
(Wiley, Hoboken, 2012)
The theoretical calculations have predicted that nonmetal-doped potassium clusters can be used in the synthesis of a new class of charge-transfer salts which can be considered as potential building blocks for the assembly ...
Isopiestic determination of the osmotic and activity coefficients of the {yKNO(3) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and ...
SFE as a superior technique for isolation of extracts with strong antibacterial activities from lichen Usnea barbata L.
(Elsevier Science Bv, Amsterdam, 2012)
The number of cases of fatal infections in humans and animals caused by multiresistant and panresistant bacterial strains has been dramatically increased over the past 10 years on almost every continent. Therefore, ...
