Formation mechanism, morphology and synthesis of alpha-Al2O3, mullite and cordierite particles obtained by the ultrasonic spray pyrolysis
(Trans Tech Publications Ltd, Durnten-Zurich, 1996)
The present stage in our investigations of the synthesis of high-purity, submicrometer and spherical Al2O3, mullite and cordierte powders obtained by the ultrasonic spray pyrolysis is presented. The influence of precursors ...
Sorption of boric acid and borax by activated carbon impregnated with various compounds
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The separation of boron compounds, boric acid and borax from aqueous solution by activated carbon before and after impregnation with various compounds was studied. A series of activated carbons was prepared from coconut ...
Boron removal by anion exchangers impregnated with citric and tartaric acids
(Taylor & Francis Inc, Philadelphia, 1996)
The separation of boron compounds, boric acid and borax, with anion-exchange resins, before and after impregnation with citric and tartaric acids, has been studied. Three different commercially available anion exchangers ...
A rheological study of behavior of polymer-bitumen blends
(Erdoel Erdgas Kohle/EKEP, 1996)
The influence of the elastomer such as SBS and SBR and their mixtures on the structure and rheological properties of blown bitumen B 65 blends, was studied. The crude oil denoted as SEB (Soviet Export Blend) was used to ...
Diureas as ligands in asymmetric reduction of ketones
(Amer Chemical Soc, Washington, 1996)
Gas-solid and gas-liquid mass-transfer coefficients
(Wiley, Hoboken, 1996)
Corrosion behaviour of polyester and fluoropolymer coatings on coil coated stainless steel
(Serbian Chemical Society, Belgrade, 1996)
Coil coated stainless steel is a new material for applications in civil and industrial fields with the purpose of reducing maintenance costs and increasing the service life of the products. The corrosion behaviour of ...
The interfacial stability of magnetically stabilized fluidized beds
(Serbian Chemical Society, Belgrade, 1996)
The study concerns a phenomenon in which the magnetization of ferromagnetic particles stabilizes the state of uniform fluidization in gas-solid, liquid-solid and gas-liquid-solid fluidized beds. Fluidization regimes and ...
Mass and momentum transfer in packed beds of spherical inert particles
(Serbian Chemical Society, Belgrade, 1996)
Mass transfer coefficients between fluid and immersed sphere in liquid dense and loose packed beds of spherical inert particles have been studied experimentally using column 40 mm in diameter. Mass transfer data were ...
Synthesis and characterization of a new chiral polyurea-based catalyst
(John Wiley & Sons Inc, New York, 1996)
A series of chiral poly(urea)s was synthesized by solution polyaddition. The polymers are characterized by NMR, FTIR, DSC, viscosimetry, and microanalysis. After deposition of the rhodium, the insoluble chiral polymers ...
