In vitro cytotoxicity assessment of intelligent acrylate based hydrogels with incorporated copper in wound management
(Elsevier Science Sa, Lausanne, 2016)
In order to evaluate biological response and potential toxicity prior to clinical use as wound dressing materials, three series of hydrogels, based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), unloaded, with ...
Dental material based on poly(methyl methacrylate) with magnesium-aluminum layered double hydroxide (MgAl-LDH) on bio-silica particles
(Elsevier B.V., 2024)
The MgAl-LDH@SiO2 particles are prepared by the coprecipitation of LDH on silica originating from plants.Particles are of submicron size and are well dispersed in the matrix. Composites consisting of PMMA reinforcedwith ...
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 ...
alpha-Tricalcium phosphate/fluorapatite based composite cements: Synthesis, mechanical properties, and biocompatibility
(Elsevier Sci Ltd, Oxford, 2020)
Composite cements based on alpha-tricalcium phosphate (alpha-TCP) and nanostructured fluorapatite (FAp), alpha-TCP/FAp, appropriate for dental usage as root canal filling material, have been prepared with the improved ...
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 ...
Optimization of modifier deposition on the alumina surface to enhance mechanical properties and cavitation resistance
(Springer, New York, 2020)
Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with ...
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 ...
