Towards antimicrobial yet bioactive Cu-alginate hydrogels
(IOP Publishing Ltd, Bristol, 2016)
The simplest approach to enhance alginate hydrogel characteristics and functional properties is to replace the calcium in the process of alginate gelation with other metallic ions which are essential for living systems. ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNa(2)HPO(4) + (1-y)K2HPO4}(aq) System at T=298.15 K
(Springer/Plenum Publishers, New York, 2016)
Isopiestic measurements have been made for aqueous mixtures of Na2HPO4 and K2HPO4 at T = (298.15 +/- 0.01) K, at Na2HPO4 ionic strength fractions y = (0.2023, 0.4060, 0.6027, 0.8007, and 1), using KCl(aq) as the reference ...

(Savez hemijskih inženjera, Beograd, 2016)
The production of bioactive peptides from egg white proteins (EWPs) and their separation are emerging areas with many new applications. The objective of this study was to compare antioxidant activity of three distinct EWP ...
Modifikovana nanoceluloza kao nosač za imobilizaciju lipaze iz Candida rugosa / Modified nanocellulose as a support for adsorption of lipase from Candida rugosa
(Beograd : Srpsko hemijsko društvo, 2016)
Sa ubrzanim razvojem nanotehnologije, celuloza kao najrasprostranjeniji i najvažniji prirodni polimer na zemiji privlači sve veću pažnju u formi nanoceluloze. Zbog svoje biodegradabilnosti, biokompatibilnosti i velike ...
Risk maps for industrial occupational health and safety / Mape rizika za zdravlje i bezbednost na radu u industriji
(Univerzitet u Nišu, Niš, 2016)
Risk assessment is a complex process, of which the outputs are often to be used by decision makers for policy development and risk management. Risk communication in Environmental sciences is often made simpler using risk ...
Synthesis, Structure and Properties of Nickel-Iron-Tungsten Alloy Electrodeposits PART II: Effect of Microstructure on Hardness, Electrical and Magnetic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
Nanostructured nickel-iron-tungsten alloys were produced by electrodeposition from an ammoniacal citrate bath. The tungsten content of the alloy ranged from 0.8 wt.% to 11 wt.%, and the crystal grain size of the FCC phase ...
In vitro multiplication of semi-dwarfing pear rootstock 'Pyrodwarf' in relation to cytokinin types
(Int Soc Horticultural Science, Leuven 1, 2016)
The most important aspect of successful micropropagation, among other in vitro factors, is to use the optimal types and concentrations of plant growth regulators. With the aim of optimization of in vitro multiplication of ...
