Added-value porous materials for controlled thymol release obtained by supercritical CO2 impregnation process
(Sage Publications Ltd, London, 2019)
This study explores utilization of biodegradable and biocompatible polymers for controlled release of natural bioactive substance. For that purpose, poly(epsilon-caprolactone) (PCL) beads, cellulose acetate (CA) film, and ...
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 ...
Zinc oxide nanoparticles prepared by thermal decomposition of zinc benzenepolycarboxylato precursors: Photoluminescent, photocatalytic and antimicrobial properties / Наночестични прахови цинк-оксида добијени термичком деградацијом цинк-бензенполикарбоксилато прекурсора: фотолуминесцентна, фотокаталитичка и антимикробна својства
(Serbian Chemical Society, 2020)
Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-source precursors at 450 °C in an air atmosphere. The mechanism and kinetics of thermal ...
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 ...

koja se može koristiti za procenu potencijalnog uticaja tehnoloških procesa na životnu
sredinu. Analizom pojedinačnih stupnjeva ...
Analysis of mechanical and structural properties of micro alloyed steel welded joints depending on quality of cored wire
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
The aim of this study was to master new quality cored wires made of steel strips and the cores filled with metal powders and low molecular hydrophobic compounds. For experimental research, the specimens were made of micro ...
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. ...
