Electrochemical stability of metformin in NaHCO3 and Na2SO4 water solution at Au, GC and IrOx electrodes
(Srpsko hemijsko društvo, Beograd, 2019)
In this study the electrochemical behavior of metformin (MET), oral antihyperglycaemic agent, was assayed at three different electrodes. The drug standard was investigated by cyclic voltammetry and square wave voltammetry ...
Modelling of pure components high pressures densities using CK-SAFT and PC-SAFT equations
(Srpsko hemijsko društvo, Beograd, 2018)
SAFT equations of state have been widely used for the determination of different thermo-physical and phase equilibria properties. In order to use these equations as predictive models it is necessary to calculate the model ...
Maltose-mediated, long-term stabilization of freeze- and spray-dried forms of bovine and porcine hemoglobin
(Srpsko hemijsko društvo, Beograd, 2019)
Slaughterhouse blood represents a valuable source of hemoglobin, which can be used in the production of heme-iron based supplements for the prevention/treatment of iron-deficiency anemia. In order to obtain a stable ...
Antibacterial activity of copper-containing clinoptilolite/PVC composites toward clinical isolate of Acinetobacter baumannii
(Srpsko hemijsko društvo, Beograd, 2015)
The multidrug-resistant bacteria Acinetobacter baumannii cause serious hospital infections. Commercial poly(vinyl chloride) (PVC) used for endotracheal tubes was modified in order to obtain a composite with an antibacterial ...
Dissolution behavior of a polyphosphate glass in simulated body fluid
(Srpsko hemijsko društvo, Beograd, 2017)
In this work, the dissolution behavior of a polyphosphate glass, with the composition 45P(2)O(5) center dot 3SiO(2) center dot 25K(2)O center dot 15CaO center dot 10MgO center dot ZnO center dot MnO (mol %), in simulated ...
ANN prediction of the efficiency of the decolourisation of organic dyes in wastewater by plasma needle
(Srpsko hemijsko društvo, Beograd, 2020)
In this paper, the results of decolourisation of Reactive Orange 16 (RO 16), Reactive Blue 19 (RB 19) and Direct Red 28 (DR 28) textile dyes in aqueous solution by plasma needle are presented. Treatment time, feed gas flow ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier
(Srpsko hemijsko društvo, Beograd, 2015)
Clinoptilolite-rich tuff (NZ) from the Zlatokop deposit (Vranjska Banja, Serbia) was studied as a nitrogen carrier for grass production. The mechanism of binding ammonium cations present in aqueous solutions by NZ was ...
Poly(methyl methacrylate) denture base materials modified with ditetrahydrofurfuryl itaconate: Significant applicative properties
(Srpsko hemijsko društvo, Beograd, 2015)
The aim of this work was to examine the possibility of modification of commercial denture base materials with itaconic acid esters, in order to obtain materials with lower toxicity and higher biocompatibility. Despite their ...
Effective valorisation of barley bran for simultaneous cellulase and beta-amylase production by Paenibacillus chitinolyticus CKS1: Statistical optimization and enzymes application
(Srpsko hemijsko društvo, Beograd, 2017)
The agricultural raw industry generates large amounts of annually by-products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and beta-amylase from ...
