Processing of dense nanostructured HAP ceramics by sintering and hot pressing
(Elsevier Sci Ltd, Oxford, 2009)
A nanosized HAP powder was sintered and hot pressed, in order to obtain dense HAP ceramics. In a first series of experiments, the powder was isostatically pressed into uniform green compacts and sintered at temperatures ...
Influence of microstructure and phase composition on the nanoindentation characterization of bioceramic materials based on hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2009)
The aim of the study was to investigate the influence of microstructure and phase composition on the mechanical behaviour of hydroxyapatite (HAp) and biphasic HAp/beta-tricalcium phosphate (beta-TCP) bioceramic materials ...
Synthesis and characterization of silver/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposite obtained by in situ radiolytic method
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This work describes radiolytic synthesis of silver nanoparticles (Ag NPs) within the poly(N-vinyl-2-pyrrolidone) (PVP) hydrogel. The hydrogel matrix was obtained by gamma irradiation-induced cross-linking, while the in ...
Thermoplastic Copolyester Elastomers
(Handbook of Engineering and Speciality Thermoplastics: Polyethers and Polyesters, 2011)
In this chapter the preparation, structure and properties of thermoplastic copolyester elastomers, TPEE, are presented. TPEEs are multiblock copolymers built up from so-called short crystallizable hard segments and long ...
Antimicrobial P(HEMA/IA)/PVP semi-interpenetrating network hydrogels
(Springer, New York, 2013)
New semi-interpenetrating networks (semi-IPNHs) (P(HEMA/IA)/PVP) were prepared by free radical crosslinking copolymerization of 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA, 5 mol%), in the presence of poly(vinyl ...
Composite nanostructured hydroxyapatite/yttrium stabilized zirconia dental inserts - The processing and application as dentin substitutes
(Elsevier Sci Ltd, Oxford, 2018)
The objective of the study was to process nano-structured hydroxyapatite/yttrium-stabilized zirconia bioceramic and to investigate the possibilities of its application as dentin replacement in the form of dental inserts. ...
Monolithic nanocrystalline SiC ceramics
(Elsevier Sci Ltd, Oxford, 2016)
Additive-free beta-SiC nanopowders were densified by using high-pressure "anvil-type with hollows" apparatus at the pressure of 4 GPa in the range of 1500-1900 degrees C. The starting powder with average particle size of ...
Improvement of the mechanical properties of paper by starch coatings modified with sepiolite nanoparticles
(Wiley-VCH Verlag Gmbh, Weinheim, 2015)
The modern and rapidly developing paper and board industry requires more efficient agents for the surface of paper in order to improve the mechanical properties. The starch coating used for the reinforcement of schrenz ...
Optimization of Al2O3 particle modification and UHMWPE fiber oxidation of EVA based hybrid composites: Compatibility, morphological and mechanical properties
(Elsevier Sci Ltd, Oxford, 2018)
Ultra-high molecular weight polyethylene (UHMWPE, PE)/oxidized PE (ox-PE) fibers and alumina reinforcement were used in preparation of poly (ethylene-co-vinyl acetate) (EVA)/hydrolyzed EVA (EVAOH) based composites. Different ...
Dual responsive antibacterial Ag-poly(N-isopropylacrylamide/itaconic acid) hydrogel nanocomposites synthesized by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Thermo- and pH-sensitive Ag-P(NiPAAm/IA) hydrogel nanocomposites were prepared by in situ reduction of Ag+ ions with gamma irradiation. P(NiPAAm/IA) copolymer hydrogel matrices have been previously synthesized by radiation ...
