Synthesis and characterization of novel semi-degradable, pH and temperature sensitive hydrogels based on 2-hydroxyethyl methacrylate and 2-hydroxyethyl acrylate
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2018)
Hydrogels represent three-dimensional hydrophilic polymer networks, capable of absorbing large quantities of water1. Due to their tissue-like characteristics, hydrogels have been widely used for a variety of biomedical and ...
Seasonal variations of concentrations of low-molecular weigth organic acids in atmospheric aerosols
(Belgrade : Public Health Institute, 2019)
In addition to inorganic ions, low-molecular weight organic acids (LMWOA) form one of the major components
of atmospheric aerosols (Djordjević et al, 2012; Joksić et al, 2009). LMWOAs contribute significantly to the
presence ...
Dielectric loss factor of jute woven fabrics: effect of alkali treatment conditions
(Belgrade : Materials Research Society of Serbia, 2019)
In this investigation, the influence of alkali treatment conditions on the dielectric loss factor of jute
woven fabric was studied. In that purpose, jute fabric has been alkali treated with NaOH solution
(1%, 5% and 17.5% ...

Enzymatic Synthesis of Aliphatic Esters of Phenolic Acids and Evaluation of Their Antioxidant Properties
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
The esterification activity of the commercial immobilized lipase CALB towards cinnamic acids and its derivative has been studied. Using cinnamic acid as substrate, the reaction rate constants (1.95 h-1 mM-1 for ethanol and ...
Thermal Resistance of Alkali Activated Binders Synthesized Using the Fly Ash and Steel Slag
(Belgrade : Materials Research Society of Serbia, 2015)
The thermal resistance of alkali-activated binders based on fly ash (FA), electric arc furnace slag (EAFS) and their FA/EAFS blends was assessed. Compressive strengths of samples before and after firing were measured. The ...
Dekolorizacija antrahinonskih boja peroksidazom iz rena imobilisanom na kaolin
(Beograd, Srpsko hemijsko društvo, 2014)
Antrahinonske boje su veoma značajne za tekstilnu industriju i, odmah nakon azo boja, imaju najveću primenu. Nažalost, kao i azo boje, i antrahinonske boje predstavljaju ozbiljan problem zagađenja životne sredine. Većina ...
Effect of substrate type on microhardness of multilayer thin film composite system
(Belgrade : Military Technical Institute, 2014)
Thin metallic multilayer films consisting of nanometer layer thickness deposited on different substrates have shown promising mechanical, electrical and magnetical properties, especially for applications in fabrication of ...
