Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
Poly[(N-isopropylacrylamide)-co-(itaconic acid)] hydrogels with poly(ethylene glycol)
(Wiley, Hoboken, 2010)
The aim of the work reported here was to investigate temperature- and pH-sensitive hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) and their semi-interpenetrating polymer networks (semi-IPNs) with varying ...
Improvement of the mechanical properties of spark plasma sintered hap bioceramics by decreasing the grain size and by adding multi-walled carbon nanotubes
(International Institute for the Science of Sintering, Beograd, 2013)
Composites based on HAP and oxidized multi-walled carbon nanotubes (o-MWCNT) and monophase HAP materials were processed by spark plasma sintering. Starting from stoichiometric nano-sized HAP powder, monophase bioceramics ...
Mechanical properties of biomorphic silicon carbide ceramics
(International Institute for the Science of Sintering, Beograd, 2011)
Biomorphous β-SiC ceramics were produced from linden wood by impregnation with tetraethyl orthosilicate (TEOS), followed pyrolysis and high temperature treatment at 1580°C. Six specimen groups included charcoal and five ...
Mechanical properties correlation to processing parameters for advanced alumina based refractories
(International Institute for the Science of Sintering, Beograd, 2012)
