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 ...
The sorption characteristics of epoxy coatings electrodeposited on steel during exposure to different corrosive agents
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Organic protective coatings on steel were formed by cathodic electrodeposition of an epoxy resin modified by an amine and isocyanate using a constant voltage method (resin concentration 10% wt, temperature 26 degrees C, ...
Extraction of cesium from an alkaline leaching solution of spent catalysts using an ion-exchange column
(Marcel Dekker Inc, New York, 1996)
The selective extraction of cesium from an alkaline leaching solution of spent catalysts using phenolic resins was studied. The resins were synthesized by alkaline polycondensation of formaldehyde by phenol, resorcinol, ...
31 P MAS NMR investigation of some microporous zincophosphates
(Serbian Chemical Society, Belgrade, 1996)
High field magic-angle spinning (MAS) 31 P-NMR investigations of novel porous zincophosphates and their cobalt-containing derivatives confirm the framework structure of alternating Zn(Co)O 4 and PO 4 tetrahedra. The MAS ...
Some aspects of the quantitative analysis of cyclic nucleotides by fast-atom bombardment mass spectrometry
(Serbian Chemical Society, Belgrade, 1996)
The possibilities of the quantitative analysis of cyclic nucleotides by fast-atom bombardment are examined. Aspects such as the amount of matrix, the formation of protonatcd ion species and the presence of more than one ...
The flow of Newtonian and drag-reducing fluids around sphere
(Serbian Chemical Society, Belgrade, 1996)
The flow around a sphere placed coaxially in a cylindrical tube, the separation of the boundary layer and the wake shedding phenomena are investigated. The results of the simultaneous determination of the drag coefficients ...
Coherent optical fiber bundles production
(Trans Tech Publications Ltd, Durnten-Zurich, 1996)
Optical fiber bundles are used in many fields of modern technology. Their production includes drawing of three layer optical fibers and sintering of the obtained fibers into a solid block. Mathematical models for two most ...
Nondispersive solvent extraction-stripping of phenol in a hollow fiber-in-fiber membrane contactor
(Serbian Chemical Society, Belgrade, 1996)
Phenol extraction from aqueous solution and its simultaneous concentration into caustic stripping solution using a hollow fiber-in-fiber type membrane contactor was investigated. The phenol separation rate using sunflower ...
