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 ...
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 ...
In vitro biocompatibility assessment of Co-Cr-Mo dental cast alloy
(Srpsko hemijsko društvo, Beograd, 2015)
Metallic materials, such as Co-Cr-Mo alloys, are exposed to aggressive conditions in the oral cavity that represents an ideal environment for metallic ion release and biodegradation. The metallic ions released from dental ...
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 ...
Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
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 ...
Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
