Experimental and theoretical study on solvent and substituent effects on the intramolecular charge transfer in 3-[(4-substituted)phenylamino]isobenzofuran-1(3H)-ones
(Srpsko hemijsko društvo, Beograd, 2018)
The substituent and solvent effects on solvatochromism in 3-[(4-substituted) phenylamino] isobenzofuran-1(3H)-ones were studied using experimental and theoretical methodologies. The effect of specific and non-specific ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
Prediction of high pressure liquid heat capacities of organic compounds by a group contribution method / Predskazivanje toplotnog kapaciteta organskih tečnosti na visokom pritisku pomoću metode doprinosa grupa
(Serbian Chemical Society, Belgrade, 2011)
A new method for estimating high pressure liquid heat capacities based on molecular structure and group contribution is proposed. A common set of structural groups was employed. The method was developed using 67 sets of ...
The critical apparent density for the free flow of copper powder / Kritična nasipna masa za tečenje praha bakra
(Serbian Chemical Society, 2003)
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 ...
Experimental investigation and modeling of thermophysical and extraction properties of choline chloride plus DL-malic acid based deep eutectic solvent
(Srpsko hemijsko društvo, Beograd, 2017)
The ability of non-toxic and biodegradable deep eutectic solvent (DES) choline chloride + DL-malic acid in mole ratio 1: 1, for the breaking of the azeotropes heptane + methanol and toluene + methanol by means of liquid-liquid ...
Interpretative optimization of the isocratic ion chromatographic separation of anions
(Srpsko hemijsko društvo, Beograd, 2016)
Interpretive retention modeling was utilized to optimize the isocratic ion chromatographic (IC) separation of the nine anions (formate, fluoride, chloride, nitrite, bromide, nitrate, phosphate, sulfate and oxalate). The ...
Design of an amino-functionalized chelating macroporous copolymer poly(GMA-co-EGDMA) for the sorption of Cu(II) ions
(Srpsko hemijsko društvo, Beograd, 2019)
Polymer-based, highly porous nanocomposites with functionalized ligands attached to the core structure are extremely efficient in the detection, removal and recovery of metals through the process of sorption. Quantum-chemical ...
Poly(methyl methacrylate) denture base materials modified with ditetrahydrofurfuryl itaconate: Significant applicative properties
(Srpsko hemijsko društvo, Beograd, 2015)
The aim of this work was to examine the possibility of modification of commercial denture base materials with itaconic acid esters, in order to obtain materials with lower toxicity and higher biocompatibility. Despite their ...
Effect of chemical treatments on the chemical composition and properties of flax fibers
(Srpsko hemijsko društvo, Beograd, 2017)
Flax fibers were modified with NaOH and NaClO2 under different conditions in order to not only clarify the effects of hemicelluloses and lignin removal on the morphology and properties of flax fibers, but also to improve ...
The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier
(Srpsko hemijsko društvo, Beograd, 2015)
Clinoptilolite-rich tuff (NZ) from the Zlatokop deposit (Vranjska Banja, Serbia) was studied as a nitrogen carrier for grass production. The mechanism of binding ammonium cations present in aqueous solutions by NZ was ...
