Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (31)) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to ...
A laboratory furnace for obtaining crystals
(Int Union Crystallography, Chester, 2004)
A design for a modular device ('crystallization shelf') installed in a laboratory furnace is presented. The setup allows regulation and simultaneous crystallization tests of several substances at different temperature ...
Aspirin polyrnorphs, exist or not?

Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures
(Taylor & Francis Ltd, Abingdon, 2004)
The excess molar volume V data of the binary liquid systems were correlated by the Peng-Robinson-Stryjek-Vera equation of state coupled with two different types of mixing rules: composition dependent van der Waals mixing ...
Water plus esters plus methanol: experimental data, correlation and prediction of surface and interfacial tensions at 303.15 K and atmospheric pressure
(Elsevier, Amsterdam, 2004)
For the ternary system water + ethyl propionate + methanol, and the constituent binaries, the surface tension at 303.15 K and atmospheric pressure was measured over the whole miscible composition range. The liquid interfacial ...
Surface composition and adsorption properties of activated carbon cloth
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The aim of this work is to gain a better fundamental understanding of the nature Of Surface oxide sites present on activated carbon cloth (ACC) surface, and their role in the adsorption process. BET surface area of ACC was ...
The influence of the hydroxylic solvents on the reaction rates of diazodiphenylmethane with cycloalkylcarboxylic and cycloalkenylcarboxylic acids
(Natl Inst Science Communication, New Delhi, 2004)
The rate constants for the reaction of diazodiphenylmethane with cyclohexylcarboxylic, cyclopentylcarboxylic, cyclohex-3-enylcarboxylic and cyclopent-3-enylcarboxylic acids have been determined in ten alcohols at 30degreesC ...
Characterization and antimicrobial activity of bacteriocin 217 produced by natural isolate Lactobacillus paracasei subsp paracasei BGBUK2-16
(Int Assoc Food Protection, Des Moines, 2004)
The strain Lactobacillus paracasei subsp. paracasei BGBUK2-16, which was isolated from traditionally homemade white-pickled cheese, produces bacteriocin 217 (Bac217; similar to7 kDa). The onset of Bac217 biosynthesis was ...
Modeling and predictions of solids dynamic holdup in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2004)
A model based on first principles and free of any semiempirical parameters is presented for trickling solids holdup in gas-flowing solids-fixed bed contactors. A small double-cone cavity is used to characterize the voids ...
