Improving the synthesis process of tribological materials based on tin sulphides by adding graphite as additive
(Journal of the Serbian Chemical Society, 2019)
The aim of this research was to study the effect of graphite addition in the process of synthesis of tribological materials based on tin sulphides. The tin sulphides powders were synthesized from selected precursors by ...
Influence of Pressure and Time on Extraction Process Using Supercritical Co2
(Technical Faculty, Bor-Serbia, Bor, 2008)
The supercritical fluid extraction (SFE) by carbon dioxide (CO2) of Salvia officinalis L. was investigated. SFE by CO2 was performed at different pressure (80, 100, 150, 200 and 300 bar) and constant temperature of 40 ...
Characterization of amyloglucosidase immobilized on the copolymer of ethylene glycol dimethacrylate and glycidyl methacrylate in simulated industrial conditions / Karakterizacija i primena amiloglukozidaze imobilizovane na makroporoznom polkgma-co-egdma) u simuliranim industrijskim uslovima
(Hemijska industrija, 2004)
The application of amyloglucosidase immobilized on the macroporous co-polymer of ethylene glycol dimethacrylate and glycidyl methacrylate (poly (GMA-co-EGDMA)) in an enzyme reactor was shown. The higher thermostability of ...
Preparation and studies on immobilized alpha-glucosidase from baker's yeast Saccharomyces cerevisiae / Dobijanje i proučavanje imobilizacije α-glukozidaze iz pekarskog kvasca Saccharomyces cerevisiae
(Serbian Chemical Soc, Belgrade, 2007)
alpha-Glucosidase from S. cerevisiae was covalently immobilized onto Sepabeads EC-EA by the glutaraldehyde method. An analysis of the variables controlling the immobilization process is first presented and it is shown that ...
Electrochemical reactivity of biologically active quinone/hydroquinone sesquiterpenoids on glassy carbon electrodes
(Bioelectrochemistry and Bioenergetics, 1987)
The redox reactivity of avarone and avarol, a quinone/hydroquinone couple isolated from the marine sponge Dysidea avara, was investigated by cyclic voltammetry, using a glassy carbon electrode. Both oxidation of avarol and ...
Radical reactions of xanthates: annulation of the cyclopentene ring / Radikalske reakcije ksantata - anelacija ciklopentenovog prstena
(Serbian Chemical Soc, Belgrade, 2007)
Homoallylic radicals, generated from the corresponding xanthates, react with terminal alkynes to give cyclopentene derivatives in moderate yields.
Possibilities for methanol content reduction in plum brandy / Mogućnosti smanjivanja sadržaja metanola u rakiji šljivovici
(Journal of Agricultural Sciences, 2005)
Several methods for reducing the methanol content of plum brandies were tried: possibilities for its reduced forming during fruit must alcohol fermentation, and employing effective and rational methods in order to decrease ...
Geochemical characterization of the hydrous pyrolysis products from a recent cyanobacteria-dominated microbial mat.
(Univ Barcelona, Barcelona, 2016)
Hydrous pyrolysis experiments were performed on a recent microbial mat sample from Lagoa Vermelha, Brazil, to determine whether crude oil can be generated and expelled during artificial maturation of the Organic Matter ...
Antimalarial peroxides: the first intramolecular 1,2,4,5-tetraoxane / Antimalarijski peroksidi - prvi intramolekulski 1,2,4,5-tetraoksan
(Serbian Chemical Soc, Belgrade, 2002)
An intramolecular steroidal 1,2,4,5-tetraoxane has been synthesised in six steps starting from methyl 3-oxo-7alpha,12alpha-diacetoxy-5beta-cholan-24-pate. The synthesised 1,2,4,5-tetra-aoxane has moderate in vitro antimalarial ...
Radical annulation methodology. 2-Vinylcyclopentane derivative formation by a 3 + 2 cycloaddition reaction
(Tetrahedron Letters, 1990)
By thermally or photolytically induced decomposition of O-acyl derivatives of N-hydroxypyridine-2-thione or other thiohydroxamic esters, in the presence of an excess of electron deficient olefins, 2-vinylcyclopentane ...
