Field performance of micropropagated rubus species
(Acta Scientiarum Polonorum, Hortorum Cultus, 2016)
The objective of this study was to test yield and fruit quality of the red raspberry 'Meeker' and the blackberry 'Cacanska Bestrna' propagated using the standard method (ST) and in vitro, by tissue culture (TC). The monitored ...
Nickel-based catalysts: Dependence of properties on nickel loading and modification with palladium
(Savez hemijskih inženjera, Beograd, 2016)
The aim of this study was comparative analysis of catalysts with 5 and 20 wt.% Ni loading, with and without Pd additive, and it included: determination of reduction degrees, investigation on microstructure by scanning ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
Multi-criteria analysis of synthesis methods for ni-based catalysts
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors ...

The present study was designed to establish and optimize a method for extracting natural bioactive compounds from Thymus serpyllum which possess antioxidant, antimicrobial, antispasmodic and stimulant properties. ...
Improvement of antioxidant properties of egg white protein enzymatic hydrolysates by membrane ultrafiltration
(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 ...
Testing of the functional garments with microencapsulated phase-change material in simulated high temperature conditions
(Savez hemijskih inženjera, Beograd, 2016)
An organic phase change material (PCM) possesses the ability to absorb and release large quantity of latent heat during a phase change process over a certain temperature range. This paper presents results related to ...
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 ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
Raman spectroscopy study of anodic film on Ag43Cu37Zn20 alloy
(Natl Inst Optoelectronics, Bucharest-Magurele, 2016)
The objective of this study was characterization of anodic film obtained when Ag43Cu37Zn20 alloy was treated electrochemically in 3.5% wt. NaCI under potentiostatic conditions. At the potential of +0.25 V a complex multilayer ...
