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 ...
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 ...
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 ...
Influence of Chitosan Coating on Mechanical Stability of Biopolymer Carriers with Probiotic Starter Culture in Fermented Whey Beverages
(Hindawi Ltd, London, 2015)
The aim of this study was to improve the mechanical stability of biopolymer carriers and cell viability with addition of chitosan coating during fermentation process and product storage. Dairy starter culture (1% (w/v)) ...
Impact of carrier material on fermentative activity of encapsulated yoghurt culture in whey based substrate
(Savez hemijskih inženjera, Beograd, 2017)
The main objectives of this paper were to study the influence of the carrier material used for encapsulation and of bead size to fermentative activity and viability of the dairy starter culture Lactoferm ABY 6. Encapsulation ...
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. ...
