Hydride reduction of B-norcholestane 5α,6α-epoxide / Hidridna redukcija B-norholestan 5α,6α-epoksida
(Serbian Chemical Society, 2002)
B-Norcholestane epoxide 2 is reduced with lithium aluminium hydride to give either the 3β,6α-diol 3 or the corresponding 3β,5α-diol 4, depending on the quality of the reducing reagent employed. Aplausible mechanistic ...
Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides: a new method for the synthesis of gamma-butanolides
(Oxford : Pergamon-Elsevier Science Ltd, 2002)
A new method for the synthesis of gamma-butanolides is described. The titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords the corresponding butyrolactones in ...
Modeling of coating optical fibers with polymer-magnetic powder composite coating
(International Institute for the Science of Sintering, Beograd, 2002)
A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Serbian Chemical Society, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
Coating of optical fibers with composite layer polymer-magnetic powder. II. Calculation of layer thickness in dependence of process parameters / Prevlačenje optičkih vlakana kompozitnom prevlakom polimer-magnetni prah II. Izračunavanje debljine prevlake u zavisnosti od procesnih parametara
(Društvo inženjera plastičara i gumara, Beograd, 2002)
The paper deals with characteristics of coating materials for optical fibers together with the obtained numerical simulation results. The basic components are defined: monomod optical fiber, poly(ethylene-co-vinyl acetate) ...
Search for source rocks of the crude oils of the Drmno depression, southern part of the Pannonian Basin, Serbia / Traganje za izvornim stenama nafti depresije Drmno, južni deo Panonskog basena, Srbija
(Serbian Chemical Society, 2002)
In a search for source rocks of the crude oils of the Drmno depression (southern part of the Pannonian Basin, Serbia), based on bulk and specific organic geochemical parameters, six out of eight Sirakovo, Bubušinac and ...
The influence of heat treatment and finishing on the mechanical properties of laminar composites
(Savez inženjera metalurgije Jugoslavije- Yugoslav Association of Metallurgical Engineers, 2002)
The aim of this investigation was to define the optimum conditions of obtaining glass fabric - epoxy resin laminar composites with appropriate mechanical properties that satisfy the quality needed for production of printed ...
Hydrodesulfurization of light gas oil - kinetic determination in a batch reactor [Hidrodesulfurizacija lakog gasnog ulja - ispitivanje kinetike HDS u šaržnom reaktoru]
(Association of the Chemical Engineers of Serbia, 2002)
The performed investigations were directed toward the analysis of the performance and activity of the fresh and regenerated Cyanamid HDS 20C catalyst in a laboratory batch reactor (2 dm3) for the HDS of the diesel fraction ...
