Biodegradation of starch-graft-polystyrene and starch-graft-poly(methacrylic acid) copolymers in model river water / Biodegradacija kalemljenih kopolimera skroba i polistirena i skroba i poli(metakrilne kiseline) u rečnoj vodi
(Serbian Chemical Soc, Belgrade, 2013)
In this paper, a biodegradation study of grafted copolymers of cornstarch and polystyrene (PS) and cornstarch and poly(methacrylic acid) in model river water is described. These copolymers were obtained in the presence of ...
Solvent effect on electronic absorption spectra of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids / Efekti rastvarača na elektronske apsorpcione spektre cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline
(Serbian Chemical Society, Belgrade, 2000)
The ultraviolet absorption spectra of cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in six protic and nine aprotic solvents in the wavelength range from 200 to 400 nm. The position ...

(Serbian Chemical Soc, Belgrade, 2006)
alpha-Glucosidase from baker's yeast was immobilized on macroporous copolymers of ethylene glycol dimethacrylate and glycidyl methacrylate, poly(GMA-co-EGDMA), with various surface characteristics and pore sizes ranging ...
Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
The estimation of solid copper surface tension in copper sulfate solutions
(Journal of the Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range, the deposition current density remains constant regardless of the deposition overpotential used, At the same time, die larger the deposition ...
Methanol oxidation at platinum electrodes in acid solution: Comparison between model and real catalysts / Oksidacija metanola na platinskim elektrodama u kiseloj sredini - poređenje model i realnih katalizatora
(Serbian Chemical Society, Belgrade, 2006)
Methanol oxidation in acid solution was studied at platinum single crystals, Pt(hkl), as the model catalyst, and at nanostructural platinum supported on high surface area carbon, Pt/C, as the real catalyst. The linear ...
The synthesis, characterization, antioxidant and antimicrobial activity of some novel amides of the esters of substituted 1,4-dihydropyridines / Синтеза, карактеризација, антиоксидативна и антимикробна активност некиx нових амида естара 1,4-дихидропиридина
(Serbian Chemical Society, 2024)
The esters of substituted 1,4-dihydropyirdines (1,4-DHP) are formed in the reaction of an appropriate aldehyde and ethyl acetoacetate in the presence of concentrated water solution of ammonia. The esters form the amides ...
Accumulation of trace metals in marine organisms of the southeastern Adriatic coast, Montenegro
(Serbian Chemical Society, 2012)
The concentration and accumulation of trace metals (Co, Ni, As, Cd, Pb and Hg) were measured in seawater, sediments and marine organisms on the coastline of Montenegro. The obtained results of trace metals in sea grass and ...
