The influence of gamma radiation on the molecular weight and glass transition of PLLA and HAp/PLLA nanocomposite
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2010)
The influence of gamma radiation on the molecular weight and glass transition behaviour of poly-L-lactide (PLLA) and hydroxyapatite/poly-L-lactide (HAp/PLLA) nanocomposite has been studied Since PLLA exposed to high-energy ...
Preparation of MEMO silane-coated SiO2 nanoparticles under high pressure of carbon dioxide and ethanol
(Elsevier, 2010)
The objective of this study is to investigate and compare methods of nanosilica coating with γ-methacryloxypropyltrimethoxy (MEMO) silane using supercritical carbon dioxide and carbon dioxide-ethanol mixture. Characterization ...
Surface characterisation of PLLA polymer in HAp/PLLA biocomposite material by means of nanoindentation and artificial neural networks
(Maney Publishing, 2010)
In this paper, the mechanical properties of polymer matrix phase (modulus of elasticity, yield stress and work hardening rate) have been determined using combined methods such as nanoindentation, finite element modelling ...
Microstructure and mechanical properties of disperse Ni-Co alloys electrodeposited on Cu substrates
(Elsevier, 2010)
The nickel and cobalt disperse alloy deposits of five different compositions were obtained by electrodeposition on Cu substrates in the galvanostatic regime from an ammonium sulfate-chloride solution. The effect of cathodic ...
Impedance response and dielectric relaxation in liquid-phase sintered Zn 2SnO 4-SnO 2 ceramics
(Springer US, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn 2SnO 4-SnO 2 ceramics. The measurements were performed over a wide ...
Crystal structure of cobalt-substituted calcium hydroxyapatite nanopowders prepared by hydrothermal processing
(Chester: International Union of Crystallography, 2010)
A series of cobalt-exchanged hydroxyapatite (CoHAp) powders with different Ca/Co ratios and nominal unit-cell contents Ca10-x Cox (PO4)6(OH)2, x = 0, 0.5, 1.0, 1.5 and 2.0, were synthesized by hydrothermal treatment of a ...
Electrical properties of barium titanate stannate functionally graded materials
(Elsevier, 2010)
Barium titanate stannate (BTS) functionally graded materials (FGMs) with different tin/titanium concentration gradient were prepared by the powder-stacking method and uniaxially pressing process, followed by sintering. ...
Study of the dendritic growth of Ni-Co alloys electrodeposited on Cu substrates
(Pennington, N. J.: The Electrochemical Society, 2010)
Ni-Co alloy deposits and their parent metals were formed on Cu substrates by electrolysis under different current densities applied in the galvanostatic regime. A quantitative scanning electron microscopy technique was ...
Photoluminescent properties of nanostructured Y2O 3:Eu3+ powders obtained through aerosol synthesis
(Elsevier, 2010)
Red emitting Y2O3:Eu3+ (5 and 10 at.%) submicronic particles were synthesized through ultrasonic spray pyrolysis method from the pure nitrate solutions at 900 °C. The employed synthesis conditions (gradual increase of ...
