Thermal shock behavior of alumina based refractories
(Techna Srl, Faenza, 2002)
Temperature difference and fracture resistance parameters have been used to predict the thermal shock behavior. Alumina based commercial refractories with different content of Al2O3 from 28% to 78% were used. Thermal and ...
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 ...
Methanol electrooxidation on supported Pt and PtRu catalysts in acid and alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% Pt-Ru (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
Interface shape and distribution of solute during Vertical Bridgman growth of Al-Cu alloy
(Elsevier, Amsterdam, 2002)
Results presented in this paper contribute to investigation of the influence of solidification rate (R) and the initial concentration of solute (C-o) on the interface shape and the distribution of the solute. Solidification ...
Electrophoretic deposition of thin alumina films from water suspension
(Elsevier, Amsterdam, 2002)
Alumina water suspensions have been prepared for thin alumina film deposition on steel. The type and quantity of deflocculant have been determined using zeta potential and viscosimetric measurements. The deposition was ...
Predictive modeling of the mechanical properties of particulate hydroxyapatite reinforced polymer composites
(Wiley, Hoboken, 2002)
The influence of particle geometry and volume fraction on the mechanical properties of a hydroxyapatite (HAp) particulate reinforced polymer (poly-L-lactide and collagen) matrix composite was investigated through finite-element ...
Influence of the semiconductor doping level on the carrier surface density in an AlGaN/GaN MODFET channel
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
In this paper the influence of doping level in AlGaN and GaN on the carriers surface density in a channel of modulation doped field effect transistors (MODFETs) has been investigated. The carriers concentration profile in ...
Normal- and reversed-phase chromatography of para-substituted propanoic acid Amides
(Springer Heidelberg, Heidelberg, 2002)
The chromatographic behavior of newly synthesized para-substituted propanoic acid amides has been studied in normal- and reversed-phase thin-layer chromatography. The retention mechanism on different TLC supports was ...
Stress corrosion cracking susceptibility of Al-Mg alloy sheet with high Mg content
(Elsevier Science Sa, Lausanne, 2002)
Slow strain rate testing (SSRT) was used to study the effect of the microstructure on the stress corrosion cracking (SCC) susceptibility of Al-Mg alloy sheet containing 6.8 wt.% Mg. In the cold-rolled and fully annealed ...
Alginate-immobilized lipase by electrostatic extrusion for the purpose of palm oil hydrolysis in lecithin/isooctane system
(Elsevier Sci Ltd, Oxford, 2002)
Lipase from Candida rugosa was immobilized in alginate beads for possible application in non-aqueous or microaqueous reaction systems. An electrostatic droplet generation technique was used for production of small diameter ...
