The effect of substrate polarity on the lipase-catalyzed synthesis of aroma esters in solvent-free systems
(Elsevier, Amsterdam, 2007)
The aim of this study was to compare activities of commercial lipases in synthesis of various esters in solvent-free system and in isooctane. Moreover, the effect of substrate polarity (expressed as log P) on solvent-free ...
Corrosion protection of aluminium by a cataphoretic epoxy coating
(Elsevier Science Sa, Lausanne, 1999)
The corrosion behavior and thermal stability of epoxy coating electrodeposited on aluminium have been investigated during exposure to 3% NaCl. Electrochemical impedance spectroscopy (EIS), gravimetric liquid sorption ...
Myeloperoxidase-mediated oxidation of organophosphorus pesticides as a pre-step in their determination by AChE based bioanalytical methods
(Springer Wien, Wien, 2010)
In order to improve the sensitivity of assays for inhibitors of the enzyme acetylcholine esterase (AChE), an effective method was developed for the conversion of the organophosphate pesticides (OPs) diazinon, malathion, ...
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 ...
Evaluation of the potential of periodically operated reactors based on the second order frequency response function
(Inst Chemical Engineers, Rugby, 2008)
A new, fast and easy method for analysing the potential for improving reactor performance by replacing steady state by forced periodic operation is presented. The method is based on Volterra series, generalized Fourier ...
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 ...
Membrane interactions of ternary phospholipid/cholesterol bilayers and encapsulation efficiencies of a RIP II protein
(Elsevier Science Bv, Amsterdam, 2008)
Membrane interactions of liposomes of ternary phospholipid/cholesterol bilayers are investigated. These interactions lead to discoidal deformations and regular aggregations and are strongly enhanced by the presence of ...
Effect of annealing temperature on the formability of Al-Mg4.5-Cu0.5 alloy sheets
(Elsevier Science Sa, Lausanne, 2006)
Formability of Al-Mg4.5-Cu0.5 alloy sheets was tested after annealing at different temperatures (220-520 degrees C) and water quenching. The formability (normalized limiting dome heights, LDH/R) showed only a small variation ...
Synthesis of functionally graded bioactive glass-apatite multistructures on Ti substrates by pulsed laser deposition
(Elsevier Science Bv, Amsterdam, 2007)
Functionally graded glass-apatite multistructures were synthesized by pulsed laser deposition on Ti substrates. We used sintered targets of hydroxyapatite Ca-10(PO4)(6)(OH)(2), or bioglasses in the system SiO2-Na2O-K2O-C ...
A correlation for heat of vaporization of pure compounds
(Korean Institute Chemical Engineers, Seoul, 2008)
Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended ...
