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 ...
Synthesis and formation mechanism of ultrafine spherical Al2O3 powders by ultrasonic spray pyrolysis
(Japan Inst Metals & Materials, Sendai, 1996)
Synthesis of high-purity submicrometer spherical particles of oc-alumina is performed by ultrasonic spray pyrolysis. As precursors, 0.5 M water solutions of both AlCl3 . 6H(2)O and Al(NO3)(3) . 9H(2)O have been used. The ...
An investigation of the synthesis of poly(L-lactide) as a biodegradable polymer for orthopaedic applications
(Serbian Chemical Society, Belgrade, 1996)
The investigation is based upon recent research in the area of the synthesis of biodegradable poly(L-lactide) (PLLA) for biomedical applications using stannous octoate (SnOct) as an initiator. The objective was to investigate ...
The time dependence of chitosan nonionic surfactant solution viscosity
(Dr Dietrich Steinkopff Verlag, Berlin 33, 1996)
The measurement of the viscosity of semiconcentrated chitosan (0.08-0.14%) solutions in the system with octaethyleneglycol mono n-dodecylether (C(12)E(8)) was carried out using Cannon-Fenske capillary viscometer. The ...
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 ...
