Preparation and modification of itaconic anhydride-methyl methacrylate copolymers / Синтеза и модификација кополимера анхидрида итаконске киселине и метил-метакрилата
(Belgrade : Serbian Chemical Society, 2007)
The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60°C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios ...
Improved synthesis and in vitro study of antimicrobial activity of α,β-unsaturated and α-bromo carboxylic acids / Optimizacija sinteze i in vitro proučavanje antimikrobnog dejstva α,β-nezasićenih i α-bromkarboksilnih kiselina
(Serbian Chemical Society, 2012)
A series of α,β-unsaturated and α-bromo carboxylic acids were identified as potent antimicrobial agents. The antimicrobial activity was evaluated using the broth microdilution method. All acids 1-12 exhibited a significant ...
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 ...
Does cholesterol bound to haemoglobin affect the anti-oxidant enzyme defence system in human erythrocytes? / Da li holesterol vezan za hemoglobin utiče na anti-oksidativni enzimski sistem u humanim eritrocitima
(Belgrade : Serbian Chemical Society, 2007)
U prethodnom radu pokazano je da lipidna frakcija koja se javlja u hemolizatu
zdravih ljudi predstavlja holesterol (asosovan sa fosfolipidima) čvrsto vezan za hemoglobin
(Hb-Ch). U ovom radu ispitivan je uticaj Hb-Ch na ...
Phytochemical study of the genus amphoricarpos / Фитохемијско истраживање биљног рода Amphoricarpos
(Serbian Chemical Society, 2021)
Phytochemistry deals with the study of secondary metabolites produced by plants that synthesize these compounds for many reasons, including their own protection against attack of herbivores and plant diseases. Secondary ...
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.
Prediction of the particle circulation rate in a draft tube spouted bed suspension dryer / Predviđanje cirkulacije čestica u sušioniku za suspenzije sa modifikovanim fontanskim slojem
(Serbian Chemical Society, 2006)
A model for predicting the particle circulation rate in a draft tube spouted bed dryer with inert particles is proposed and verified. The calculation algorithm requires three input values: the gas velocity in the draft ...
Carbon monoxide oxidation on bimetallic Ru/Au(111) surfaces / Оксидација CO на биметалним Ru/Au(111) површинама
(Belgrade : Serbian Chemical Society, 2001)
The electrochemical deposition of Ru on Au(111) was performed in 0.5 M H2SO4 + 10-4 M RuCl3. The obtained bimetallic Ru/Au(111) surfaces were characterised by cyclic voltammetry and in situ STM in 0.5 M H2SO4. The Ru deposit ...
Spectroscopic properties and antimicrobial activity of dioxomolybdenum(VI) complexes with heterocyclic S,S'-ligands / Spektroskopska svojstva i antimikrobna aktivnost dioksomolibden(VI) kompleksa sa heterocikličnim S,S'-ligandima
(Srpsko hemijsko društvo, Beograd, 2012)
Five new dioxomolybdenum(VI) complexes of the general formula [MoO2(Rdtc)2], 1-5, where Rdtc- refer to piperidine (Pipdtc), 4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), piperazine (Pzdtc) or N-methylpiperazine ...
Characterization and corrosion properties of electrodeposited Ni-W alloys / Karakterizacija i korozione karakteristike elektrohemijski taložene legure Ni-W
(Serbian Chemical Society, 2001)
Ni-W alloys electrodeposited from citrate solution consist of three different phases, which are all present in high W-content alloys: a solid solution of W in a Ni matrix; an intermetallic compound Ni4W, as well as another ...
