Removal of Pb2+ from aqueous solution by P(HEA/IA) hydrogels
(Savez hemijskih inženjera, Beograd, 2016)
A series of poly(2-hydroxyethyl acrylate-co-itaconic acid), P(HEA/IA), hydrogels with different HEA/IA ratio, were synthesized using free radical crosslinking/copolymerization and investigated as sorbents for Pb2+ from ...
Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...
Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Elsevier Ltd., 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
Epoxy-silanization - tool for improvement of silica nanoparticles as support for lipase immobilization with respect to esterification activity
(Wiley, Hoboken, 2016)
BACKGROUND: In this study, in order to obtain the best support for the immobilization of lipase from Candida rugosa (CRL), the procedure for chemical modification of fumed silica nanoparticles (FNS) with (3-Glycidyloxypropyl) ...
Numerical simulation of the plunge stage in friction stir welding / Numerička simulacija faze uranjanja kod zavarivanja trenjem mešanjem
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
This paper investigates the plunge stage using numerical modeling. A three-dimensional finite element model (FEM) of the plunge stage is developed using the commercial code ABAQUS to study the thermo-mechanical processes ...
Advantage of use of activated flux-cored wire instead of solid wire with the mag welding process from the mechanical properties aspect

Selection of Lactobacillus strains for improvement of antioxidant activity of different soy, whey and milk protein substrates
(Journal of Hygienic Engineering and Design, 2016)
Due to the health benefits and potential food preservative applications, natural antioxidants were recently attracted great attention of many food manufacturers which tend to produce healthy foods. The special challenge ...
Quality of fermented whey beverage with milk
(Savez hemijskih inženjera, Beograd, 2016)
One of the most economical ways of whey processing is the production of beverages, which represents a single process that exploits all the potential of whey as a raw material. Functional and sensory characteristics of ...
Graphene Based Composite Hydrogel for Biomedical Applications
(Croatian Chemical Soc, Zagreb, 2017)
In this work, composite hydrogel consisting of poly(vinyl alcohol), graphene and silver nanoparticles, (Ag/PVA/Gr), was prepared by the immobilization of silver nanoparticles (AgNPs) in PVA/Gr hydrogel matrix in two steps. ...
