Catalytic center of cytochrome c oxidase: Effects of protein environment on pKa values of Cub histidine ligands / Каталитички центар цитохром оксидазе: утицај протеинског окружења на pka вредности хистидинских лиганада Cub центра
(Belgrade : Serbian Chemical Society, 2020)
The molecular mechanism by which electron transfer (ET) is coupled to proton pumping in cytochrome oxidase is one of the main unsolved problems in biochemistry. Particularly, the nature and position of the proton-loading ...
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 ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
Surface roughness minimum: Ag thin layer deposited on a glass / Minimum površinske hrapavosti: tanki sloj Ag deponovan na staklu
(Belgrade : Serbian Chemical Society, 2001)
In this paper the results of an examination of the surface roughness and morphology dependence of silver thin films up to 100 nm thick deposited on a microscope glass on the deposition rate and on the deposition time are ...
Adhesion of epoxy cataphoretic coatings on Zn alloys / Адхезија епоксидних катафоретских превлака на легурама цинка
(Belgrade : Serbian Chemical Society, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of coating adhesion under environmental influence. In this work, the adhesion of epoxy cataphoretic coatings was examined on steel ...
Elimination of Nucleation Exclusion Zones by Electrodeposition at a Reversing Current / Eliminacija zona isključenja nukleacije taloženjem reversnom strujom
(Belgrade : Serbian Chemical Society, 1998)
Elimination of nucleation exclusion zones by electrodeposition at a reversing current (RC) in the seconds time range is considered. It is shown that nucleation exclusion zones formed in constant regimes can be eliminated ...
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 ...
Assessment of density functional approximations for calculation of exchange coupling constants in thiocyanato and cyanato double bridged binuclear Ni(II) complexes / Испитивање апроксимативних функционала густине за израчунавање константи купловања у двоструко премошћеним тиоцијанато и цијанато бинуклеарним Ni(II) kомплексима
(Belgrade : Serbian Chemical Society, 2020)
In the present work, we examine the magnetic properties of 8 “end-to-end” thiocyanato, and 3 “end-to-end” cyanato double bridged Ni(II) binuclear complexes. Thiocyanato complexes are weakly ferromagnetic. Cyanato bridged ...
Elicitation effects of a synthetic 1,2,4,5-tetraoxane and a 2,5-diphenylthiophene in shoot cultures of two Nepeta species
(Serbian Chemical Society, 2016)
The presented study aimed to investigate the elicitation possibility for the production of main secondary metabolites in Nepeta cataria L. and N. pannonica L. plants, by exposing them to synthetic compounds belonging to ...
Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Serbian Chemical Society, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
