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 ...
Conventional and spark-plasma sintering of cordierite powders synthesized by sol-gel methods
(Elsevier Sci Ltd, Oxford, 2013)
Cordierite powders synthesized by colloidal and alkoxide sol-gel methods were conventionally and spark-plasma sintered. The powders for the sintering investigations were obtained by calcination of the gels at a temperature ...
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. ...
Crystallization behavior and sintering of cordierite synthesized by an aqueous sol-gel route
(Elsevier Sci Ltd, Oxford, 2012)
The purpose of the research was to investigate crystallization behavior and sintering of cordierite synthesized by a low-price aqueous sol gel route starting from silicic acid and magnesium and aluminum salts. Viscous ...
Physical-mechanical and microstructural properties of alkali-activated fly ash-blast furnace slag blends
(Elsevier Sci Ltd, Oxford, 2015)
This paper investigated physical mechanical and microstructural properties of alkali-activated binders based on blends of fly ash (FA) and blast furnace slag (BFS). FA BFS blends were alkali-activated with sodium silicate ...
Polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics fabricated by Spark Plasma Sintering: Densification and microstructure development
(Elsevier Sci Ltd, Oxford, 2014)
Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 ...
Enhanced thermo-mechanical properties of acrylic resin reinforced with silanized alumina whiskers
(Elsevier Sci Ltd, Oxford, 2016)
The acrylic resin reinforced with silanized alumina whiskers with self-healing (SH) agents was synthesized. The self-healing system consisted of microcapsules with the healing agent dicyclopentadiene (DCPD) and modified ...
Spark plasma sintering of ZrC-SiC ceramics with LiYO2 additive
(Elsevier Sci Ltd, Oxford, 2013)
Spark plasma sintering (SPS) of ZrC-SiC composite powders in the presence of LiYO2 sintering additive was studied. The starting powders were obtained by a carbothermal reduction (CTR) of natural mineral zircon (ZrSiO4), ...
Core-shell superparamagnetic iron oxide nanoparticle (SPION) clusters: TEM micrograph analysis, particle design and shape analysis
(Elsevier, 2016)
For the first time, particle shape analysis of silica coated iron oxide (maghemite/magnetite) nanoparticle clusters (core-shell nanostructures) is discussed using computational methods. We analyzed three samples of core-shell ...
CdS quantum dots sensitized TiO2 nanotubes by matrix assisted pulsed laser evaporation method
(Elsevier Sci Ltd, Oxford, 2016)
Within this study a matrix assisted pulsed laser evaporation technique was employed for deposition of CdS quantum dots onto TiO2 nanotubes. The number of laser pulses and laser fluence were varied to control the amount of ...
