Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier Science Sa, Lausanne, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was ...
Titanium dioxide nanoparticles surface modified with imine as fillers for epoxy resin / Nanočestice titan-dioksida površinski modifikovane iminom kao punioci za epoksidnu smolu
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2018)
The surface of anatase TiO2 nanoparticles was modified with in situ synthesized imine, based on 3,4-dihydroxybenzaldehyde and octadecylamine. The modified TiO2 nanoparticles were investigated using FTIR and UV-Vis spectroscopy, ...
Hydrometallurgical Process for Selective Metals Recovery from Waste-Printed Circuit Boards
(MDPI, Basel, 2018)
This paper presents an experimentally-proved hydrometallurgical process for selective metals recovery from the waste-printed circuit boards (WPCBs) using a combination of conventional and time-saving methods: leaching, ...
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 ...
Resveratrol loaded liposomes produced by different techniques
(Elsevier Sci Ltd, Oxford, 2013)
Several different methods for production of liposomes incorporating resveratrol were investigated and compared from the aspect of size distribution, surface charge, entrapment efficiency, phase behavior and stability. Thin ...
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 ...
Hydrothermal synthesis of TiO2/carbon composites and their application for removal of organic pollutants
(Elsevier, Amsterdam, 2019)
TiO2/carbon composites were synthesized by hydrothermal carbonization, using titanium isopropoxide and glucose precursor solution to obtain composites with Ti/C molar ratios ranging from 0.05 to 0.30. Characterization of ...
