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. ...
Anodization of Ti-based materials for biomedical applications: A review
(Association of Metallurgical Engineers of Serbia, 2016)
Commercially pure titanium (cpTi) and titanium alloys are the most commonly used metallic biomaterials. Biomedical requirements for the successful usage of metallic implant materials include their high mechanical strength, ...

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 ...
Mechanical properties and microstructure of the ZrO25CaO/NiCrAl coating system / Mehaničke osobine i mikrostruktura sistema prevlaka ZrO25CaO/NiCrAl
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
ZrO25CaO is a versatile class of material that can be sintered or plasma spray deposited in combination with other materials on the implant substrate. Due to brittleness the organic ceramic hydroxyapatite Ca10(PO4)6(OH)2 ...
Friction-stir welding of high-strength aluminium alloys and a numerical simulation of the plunge stage
(Institute of Metals and Technology, 2012)
This paper defines a set of welding parameters for the Friction-Stir Welding (FSW) of two forged panels of the alloy EN AW 7049A in a T652 temper and discusses the plunge stage of FSW using numerical modeling. This ...
A coupled thermo-mechanical model of friction stir welding
(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
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 ...
