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 ...
Formation of Disperse Silver Deposits by the Electrodeposition Processes at High Overpotentials
(Esg, Belgrade, 2012)
In this study, electrodeposition of silver from nitrate solution at the high overpotentials was analyzed. Morphologies of silver deposits obtained at the different overpotentials and with the different electrodeposition ...
A Voltammetric Method for the Quantitative Determination of Midecamycin Compared to Its Simultaneous HPLC Determination
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The aim of this study was to present the quantitative determination of midecamycin at a gold electrode in 0.05 M NaHCO(3) using cyclic linear sweep voltammetry. It was found that the value of the oxidative peak of pure ...
Characterization of copper powder particles obtained by electrodeposition as function of different current densities
(Journal of Applied Electrochemistry, 2009)
Technological properties of powders depend on their granulometry and morphology. Very often one method is inadequate for characterization of powder particles. This article studied different methods intended for clear ...
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 ...
Decorated Ru/Au(111) and Os/Au(111) surfaces: An in situ STM and electrochemistry study
(Russia : Maik Nauka-Interperiodica Publishing, 2006)
The structure and reactivity of bimetallic electrodes obtained by spontaneous deposition of Ru and Os on Au(111) single-crystal surfaces are studied. In situ electrochemical STM and cyclic voltammetry are used to characterize ...
Mutual influence of parallel, CH/O, OH/pi and lone pair/pi interactions in water/benzene/water system
(Elsevier, 2013)
The mutual influence of OH/pi, CH/O, parallel alignment (all attractive) and lone pair/pi (repulsive) water/benzene interactions was studied with ab initio calculations on water/benzene/water systems. The energies of the ...
