Electrooxidation of H-2, CO and H-2/CO mixtures on a well-characterized Pt-Re bulk alloy electrode and comparison with other Pt binary alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
We report new results for the electrooxidation of Hz, CO and H-2/CO mixtures on a Pt75Re25 bulk alloy using surface preparation in a UHV chamber and characterization by X-ray photoelectron spectroscopy (XPS). Sputter-cleaned ...
Correlation between apparent activation energy for hot working and temperature of no recrystallization in microalloyed steels
(Trans Tech Publications Ltd, Durnten-Zurich, 2003)
Two-stage linear ln[sinh(as)] vs 1/T plots, based on the stress data derived from either continuous or multipass flow curves generated by testing low carbon Nb/Ti microalloyed steel (Nb steel) and medium carbon V-microalloyed ...
Thermodynamic modeling of vapor-liquid equilibria and excess properties of the binary systems containing diethers and n-alkanes by cubic equation of state
(Korean Institute Chemical Engineers, Seoul, 2004)
A comparison of the performances of two different approaches of cubic equations of state models, based on a classical van der Waals and mixing rules incorporating the G(E) equation, was carried out for correlation of ...
Adhesion and corrosion resistance of epoxy primers used in the automotive industry
(Taylor & Francis Ltd, Abingdon, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of adhesion of the coating under environmental influence. Thus, adhesion strength is often used when characterizing protective ...
Immobilization of lipase from Candida rugosa on a polymer support
(Springer, New York, 1998)
Lipase from Candida rugosa was immobilized by adsorption onto a macroporous copolymer support. Under optimum conditions the maximum amount of protein bound was 15.4 mg/g and the immobilization efficiency was 62%. The ...
Template effect in caesium selective phenolic resins
(Kluwer Academic Publ, Dordrecht, 1998)
Two new phenolic resins have been synthesised by alkaline polycondensation of resorcinol and acetaldehyde using template polymerisation. The extraction properties of the resins have been evaluated in competitive extraction ...
Finite element modeling of mechanical properties of particulate composite biomaterials
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
The influence of inclusion geometry and volume fraction on stiffness behavior of a particle hydroxyapatite filled polymer (poly-L-lactide and collagen) matrix composite was investigated by finite element. analysis. The ...
Total lipids of the intramuscular tissue of fallow deer - Non-isothermal, non-oxidative and oxidative TG
(Springer, Dordrecht, 2007)
In this study non-isothermal non-oxidative and oxidative TG analysis was applied as a method for determining the thermal stability of the total lipids extracted from raw and maturing intramuscular tissue of fallow deer ...
New analytical HFET I-V characteristics model
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
In this paper the new analytical model of current - voltage characteristics of a Heterostructure Field Effect Transistor (HFET), is proposed. The model is relatively simple, and at the same time, it describes complex HFET ...
The Candida rugosa lipase catalyzed synthesis of amyl isobutyrate in organic solvent and solvent-free system: A kinetic study
(Elsevier, Amsterdam, 2006)
The Candida rugosa lipase catalyzed esterification of butyric acid with amyl alcohol in isooctane and in solvent-free system was studied. Nearly complete conversion ( gt 95%) of substrates was achieved using low enzyme ...
