Micromechanical properties of a hydroxyapatite/poly-L-lactide biocomposite using nanoindentation and modulus mapping
(Elsevier Sci Ltd, Oxford, 2007)
Biocomposites with ceramic fillers and polymer matrix are becoming attractive materials for bone tissue replacements. Nanoindentation has been used to locally characterize the surface mechanical properties of the ...
Electrical properties of cordierite obtained by non-hydrolytic sol-gel method
(Elsevier Sci Ltd, Oxford, 2007)
Cordierite ceramic material, due to its properties such as low thermal expansion coefficient, low dielectric constant and high specific resistivity, could be used as an insulating material in high-frequency electronics. ...
Bioactive glass-apatite composite coating for titanium implant synthesized by electrophoretic deposition
(Elsevier Sci Ltd, Oxford, 2007)
Titanium and titanium alloys are widely used as materials for implants, because of their mechanical properties and nontoxic behaviour, but unfortunately, are bioinert. In order to solve this problem, the metal implant could ...
Nonlinear properties and stability of SnO2 varistors prepared by evaporation and decomposition of suspensions
(Elsevier Sci Ltd, Oxford, 2005)
SnO2 varistors doped with CoO, Cr2O3 and Nb2O5 were prepared by evaporation and decomposition of suspensions. The composition of the varistors was optimized to improve electrical properties, such as nonlinearity, leakage ...
Determination of thermal shock resistance of silicon carbide/cordierite composite material using nondestructive test methods
(Elsevier Sci Ltd, Oxford, 2008)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70 and 50:50. Behavior of composite ceramics after thermal ...
Assessment of viscoelastic crack bridging toughening in refractory materials
(Elsevier Sci Ltd, Oxford, 2008)
Viscoelastic bridges can be formed in refractory ceramics while cooling from high temperatures. Such bridges can shield crack tips, thus reducing the effective crack tip stress intensity factors leading to higher resistance ...
Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors
(Elsevier Sci Ltd, Oxford, 2007)
Lanthanum nickel oxide (LaNiO3) is an electrically conductive ceramics, which has a potential use as electrode for ferroelectric thin films, multilayer actuators and many other electronic devices. In this work, LaNiO3 thin ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier Sci Ltd, Oxford, 2004)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
