7, 8, 15, 16-Tetraoxa-dispiro [5. 2. 5. 2]hexadecane-3-carboxylic acid derivatives and their antimalarial activity / Antimalarijska aktivnost derivata 7,8,15,16-tetraoksa-dispiro5.2.5.2heksadekan-3-karboksilne kiseline
(Serbian Chemical Society, 2004)
Several C2 symmetrical mixed tetraoxanes were prepared starting from a gemdihydroperoxide and a ketone. The obtained tetraoxanes showed pronounced antimalarial activity against P. falciparum chloroquine resistant W2 and ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
Surface roughness minimum: Ag thin layer deposited on a glass / Minimum površinske hrapavosti: tanki sloj Ag deponovan na staklu
(Belgrade : Serbian Chemical Society, 2001)
In this paper the results of an examination of the surface roughness and morphology dependence of silver thin films up to 100 nm thick deposited on a microscope glass on the deposition rate and on the deposition time are ...
The chemical characteristics of soil which determine phosphorus partitioning in highly calcareous soils / Hemijske karakteristike visoko-krečnjačkih zemljišta koje određuju raspodelu fosfora
(Serbian Chemical Society, 2006)
Phosphorus fractions from three highly calcareous soils (average, 24.9 ± 4.8 %CO3 2-) from sampling sites with a Mediterranean climate were isolated by sequential extraction. In order to provide a more reliable basis for ...
The effect of perpendicularly oriented magnetic field on the formation of very disperse iron structures / Uticaj vertikalno orijentisanog magnetnog polja na formiranje veoma disperznih struktura gvožđa
(Serbian Chemical Society, 2006)
Iron deposits obtained without and with a perpendicularly oriented magnetic field were examined by scanning electron microscopy (SEM). It was found that the iron deposit obtained under a perpendicularly oriented magnetic ...
Preparation and studies on immobilized alpha-glucosidase from baker's yeast Saccharomyces cerevisiae / Добијање и проучавање имобилизације α-глукозидазе из пекарског квасца Saccharomyces cerevisiae
(Belgrade : Serbian Chemical Society, 2007)
α-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 the ...
Process improvement approach to the acid activation of smectite using factorial and orthogonal central composite design methods / Faktorijalni i ortogonalno centralno kompozitni plan eksperimenta kiselinske aktivacije smektita
(Serbian Chemical Society, 2008)
The purpose of this study was to determine the effective operating parameters and the optimum operating conditions of an acid activation process within the framework of improvement of the process. Full two-level factorial ...
The effects of a magnetic field on the morphologies of nickel and copper deposits: The concept of 'effective overpotential' / Uticaj primenjenih magnetnih polja na morfologije taloga nikla i bakra - koncept 'efektivne prenapetosti'
(Serbian Chemical Society, 2007)
The morphologies of nickel and copper deposits obtained without applied magnetic fields, and with both parallel and perpendicular applied magnetic fields were examined by the scanning electron microscopy (SEM) technique. ...
Bacterially generated Fe2(SO4)3 from pyrite, as a leaching agent for heavy metals from lignite ash / Bakterijski generisani Fe2(SO4)3 iz pirita kao agens za luženje elektrofilterskog pepela termoelektrane iz procesa sagorevanja lignita
(Serbian Chemical Society, 2007)
Investigations of heavy metals from lignite ash, which is a coal combustion by-product, have for years been very interesting from different aspects of environmental protection. In this study, the possibility of microbiological ...
Intramolecular Barbier reaction in water: Cyclopentane and cyclohexane ring closure / Intramolekulska Barbier-ova reakcija u vodi - sinteza petočlanih i šestočlanih prstenova
(Serbian Chemical Society, 2002)
Zinc or indium promoted intramolecular Barbier reactions of aldehydes containing a suitably positioned allylic or propargylic halide unit afford unsaturated cyclic alcohols in moderate yields.
