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 ...
Influence of hematite nanorods on the mechanical properties of epoxy resin
(Srpsko hemijsko društvo, Beograd, 2017)
The mechanical properties of nanocomposites obtained by incorporation of fairly uniform hematite nanorods (alpha-Fe2O3 NRs) into epoxy resin were studied as a function of the content of the inorganic phase. A thorough ...
Current efficiency in the chlorate cell process
(Srpsko hemijsko društvo, Beograd, 2014)
A mathematical model has been set up for current efficiency in a chlorate cell acting as an ideal electrochemical tubular reactor with a linear increase in hypochlorite concentration from the entrance to the exit. Good ...
A survey on the characterization and biological activity of isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2020)
The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. ...
Influence of the aerosol flow and exposure time on the structural changes in the filtering half masks material
(Srpsko hemijsko društvo, Beograd, 2018)
The flow of air and aerosol particles through the filtering half masks material depends on the structure porosity. It is very difficult to determine the behaviour of the filtering material during the process of extraction ...
Improving the synthesis process of tribological materials based on tin sulphides by adding graphite as additive
(Srpsko hemijsko društvo, Beograd, 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 ...
Continuous flow synthesis of some 6-and 1,6-substituted 3-cyano-4-methyl-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2019)
In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to ...
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 ...
Structural, spectral and thermal properties of 2-(2-pyridylamino)pyridinium trihydrogen pyromellitate / Структурна, спектрална и термичка својства 2-(2-пиридиламино)пиридиниjум-трихидрогенпиромелитата
(Srpsko hemijsko društvo, 2014)
The title compound, (Hdipya)(H(3)pyr), where Hdipya is protonated 2,2'-dipyridilamine and H(3)pyr is the monoanion of pyromellitic acid (H(4)pyr), was obtained from a reaction mixture containing Zn(II) ions, dipya, Na(4)pyr ...
Applicability of zeolites in potassium and nitrate retention in different soil types
(Srpsko hemijsko društvo, Beograd, 2017)
Environmental protection and sustainable agricultural production require the use of inexpensive and environmentally acceptable soil supplements. Objectives of this study were to investigate the influence of the addition ...
