Lipase-catalyzed synthesis of biodiesel in solvent-free system with different acyl acceptors
(Elsevier Science Bv, Amsterdam, 2009)
Experimental determination and modelling of densities and excess molar volumes of ternary system (1-butanol + cyclohexylamine plus n-heptane) and corresponding binaries from 288.15 to 323.15 K
(Elsevier Science Bv, Amsterdam, 2009)
Experimental densities rho and excess molar volumes V-E of one ternary and three binary systems containing 1-butanol, cyclohexylamine and n-heptane at temperatures from 283.15 to 323.15 K are reported. Density measurements ...
Swelling behaviour and paracetamol release from poly(N-isopropylacrylamide-itaconic acid) hydrogels
(Springer, New York, 2009)
Copolymer hydrogels of N-isopropylacrylamide and itaconic acid (IA), crosslinked with N,N'-methylenebisacrylamide, were prepared by radical copolymerization. These hydrogels were investigated with regard to their composition ...
Influence of Hydrolysis on the Osmotic Coefficients of the System {yZnCl(2) + (1-y)ZnSO4}(aq) at Temperature 298.15 K
(Amer Chemical Soc, Washington, 2009)
Isopiestic vapor pressure measurements were made for {yZnCl(2) + (1 - y)ZnSO4}(aq) solutions with ZnCl2 ionic strength fractions of y = (0.2640, 0.5042, 0.7533, and 1) at the temperature 298.15 K, using KCl(aq) as the ...
Electrochemical deposition and corrosion stability of Zn-Co alloys
(Springer, New York, 2009)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using anodic linear sweep voltammetry for phase structure determination, scanning electron microscopy for surface morphology ...
Experimental research of characteristics of shock absorbers of impact energy of passenger coaches

Electrophoretic Deposition of Biocomposite Lignin/Hydroxyapatite Coatings on Titanium
(Walter de Gruyter Gmbh, Berlin, 2009)
In this work, electrophoretic deposition (EPD) was applied to obtain novel hydroxyapatite (HAP)/lignin (Lig) biocomposite coatings on titanium substrate. Nanosized hydroxyapatite powder, prepared by using the modified ...
Electrochemical synthesis of nanosized monetite powder and its electrophoretic deposition on titanium
(Elsevier Science Bv, Amsterdam, 2009)
Electrochemical synthesis of nanosized monetite powder was performed galvanostatically from homogeneous Solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Journal of Electroanalytical Chemistry, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Synthesis, characterization and cytotoxicity of surface amino-functionalized water-dispersible multi-walled carbon nanotubes
(Elsevier Science Bv, Amsterdam, 2009)
Surface functionalization of multi-walled carbon nanotubes (MWCNTs), with amino groups via chemical modification of carboxyl groups introduced on the nanotube surface, using O-(7-azabenzotriazol-1-yl)-N, N,N',N'-tetramethyluronium ...
