Synthesis, antimicrobial and antioxidative activity of some new isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2014)
The isatin derivatives, Schiff bases, were synthesized by the reaction of isatin and various substituted primary amines and characterized by several spectroscopic methods. Investigation of the antimicrobial activity of the ...
On the possibility of the direct preparation of the sodium salt of copper phthalocyanine-4-sulfonic acid
(Serbian Chemical Society, 1994)
The reaction of a 1:3 molar mixture of the monosodium salt of 4-sulfophthalic acid and phthalic acod, carried out in the presence of NH4Cl, urea, CuSO4 5H2O, and (NH4)2MoO4, does not yield the mono-substituted derivative, ...
On the determination of copper in its phthalocyanine complex
(Journal of the Serbian Chemical Society, 1993)
A convenient method for copper analysis in copper phthalocyanine and its ring-substituted derivates has been studied. It is based on the complete destruction of the organic component in the sample by a combination of thermal ...
Solvatochromism of isatin based Schiff bases: An LSER and LFER study
(Srpsko hemijsko društvo, Beograd, 2016)
The derivatives of isatin (1H-indole-2,3-dione) have already been reported to show a variety of biological activities. However, there have hitherto been no reports on the solvatochromic effects of isatin derivatives, and ...
Novel negatively charged membrane adsorbers made using a combination of photopolymerization and immersion precipitation
(Srpsko hemijsko društvo, Beograd, 2016)
A novel method combining a traditional immersion precipitation process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution was used to prepare asymmetric ...
The porosity and roughness of electrodeposited calcium phosphate coatings in simulated body fluid
(Srpsko hemijsko društvo, Beograd, 2015)
Calcium phosphate coatings were electrochemically deposited on titanium from an aqueous solution of Ca(NO3)(2) and NH4H2PO4 at a current density of 10 mA cm(-2) for a deposition time of 15 mm. The obtained brushite coatings ...
Mechanical characterization of copper coatings electrodeposited onto different substrates with and without ultrasound assistance
(Srpsko hemijsko društvo, Beograd, 2019)
The mechanical properties of systems consisting of copper coatings electrodeposited on both brass sheet (BS) and thick electrodeposited nickel coating (ED Ni) substrates have been investigated. The electrodeposition of ...
Statistical optimization of bioethanol production from waste bread hydrolysate
(Journal of the Serbian Chemical Society, 2021)
A recent trend in sustainable bioethanol production is the use of agricultural waste or food waste as an inexpensive and the most available feedstock. Bread waste is the major food waste that could be successfully used for ...
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 ...
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 ...
