Synthesis of mullite nanostructured spherical powder by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
In this paper the synthesis of nanostructured spherical particles of mullite powders by ultrasonic spray pyrolysis is presented. The mullite crystallization and the nanostructure development during heating were examined ...
Blends of thermoplastic starch and some thermoplastic polymers
(Serbian Chemical Society, Belgrade, 1998)
Thermoplastic starch (TPS) was blended in a twin screw mixer with 5 and 10 mass % of poly(ethylene-co-acrylic acid) (EAA), poly(ethylene-co-vinyl acetate) (EVA) or cellulose acetate (CA) in order to improve the TPS properties. ...
Adsorption thermodynamics of organics on nickel- and copper-hexacyanoferrates
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
Adsorption of various organics on Ni- and Cu-hexacyanoferrates was investigated by gas-solid chromatography (inverse gas chromatography). Adsorption was studied in the temperature region from 80 to 95 degrees C at zero ...
Viscoelastic properties of Na-carboxymethylcellulose solutions
(Serbian Chemical Society, Belgrade, 1998)
The rheological characteristics of 5% solutions of Na-carboxymethylcellulose (CMC)I of various origin were investigated. Depending on the molar mass (1.25-1.94 x 10(5) g mol(-1)), i.e., the degree of polymerization (545-851) ...
Cubic equation of state models for the liquid excess heat capacity calculations. I. Mixing rules
(Serbian Chemical Society, Belgrade, 1998)
Binary liquid excess heat capacities, c(p)(E), were calculated by the PRSV EOS coupled with the van der Waals one fluid (vdW), the modified van der Waals one fluid (Schwartzentruber-Renon)(SR) and the Orbey-Sandler ...
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 ...
Electrochemically deposited thin films of amorphous Fe-P alloy Part I. Chemical composition and phase structure characterization
(Elsevier Science Sa, Lausanne, 1998)
Thin Fe-P alloy films (0.5 to 25.0 mu m thick) were electrodeposited from sulfate solutions. The influences of various deposition conditions (current density, time, pH and temperature) on the composition and structure of ...
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 ...
Kinetics of the reactions of pyridine and pyridine-N-oxide carboxylic acids and substituted benzoic acids with diazodiphenylmethane in various alcohols
(Sage Publications Ltd, London, 1998)
Solvent effects on the reactivity of pyridine and pyridine-N-oxide carboxylic acids and p-substituted benzoic acids in their reaction with diazodiphenylmethane (DDM) in alcohols have been investigated and the rate constants ...
Synthesis of cordierite powder performed under the conditions of periodic ultrasonic fields activity
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
In this article, the influence of periodic physical field, on the given system, is presented by the example of the ultrasonic spraying of various aerosol precursors used for ceramic powder synthesis. A general model, ...
