Facile synthesis of poly(ε-caprolactone) micro and nanospheres using different types of polyelectrolytes as stabilizers under ambient and elevated temperature
(Elsevier, 2013)
Poly(ε-caprolactone) (PCL) particles were prepared by physicochemical method with solvent/non-solvent systems. The synthetic polymer polyvinylpyrrolidone (PVP) and natural polymer poly(α,γ,l-glutamic acid) (PGA), were used ...
Ti substrate coated with composite Cr–MoO2 coatings as highly selective cathode materials in hypochlorite production
(Elsevier, 2013)
The aim of this work was to investigate the possibility of preparation of the composite Cr–MoO2 coatings onto steel and titanium substrates as cathode materials with high selective properties which imply the suppression ...
Structural, morphological and luminescence properties of nanocrystalline up-converting Y1.89Yb0.1Er0.01O3 phosphor particles synthesized through aerosol route
(Elsevier, 2013)
Nanocrystalline up-converting Y2O3:Yb3+, Er3+ phosphor particles were processed in a dispersed system-aerosol, generated ultrasonically at 1.3 MHz from common nitrate precursor solution having fixed ytterbium-to-erbium ...
Facile Solvothermal Preparation of Monodisperse Gold Nanoparticles and Their Engineered Assembly of Ferritin–Gold Nanoclusters
(Elsevier, 2013)
Herein, we report a quick and simple synthesis of water-soluble gold nanoparticles using a HAuCl4 and oleylamine mixture. Oleylamine serves as a reduction agent as well as a stabilizer for nanoparticle surfaces. The particle ...
Y2O3:Yb,Tm and Y2O3:Yb,Ho powders for low-temperature thermometry based on up-conversion fluorescence
(Elsevier, 2013)
Recently, trivalent rare earth doped materials have received significant attention due to the strong temperature dependence of the fluorescence emission of these materials, which can be useful in temperature sensing. Here, ...
Preparation and properties of porous, biomorphic, ceria ceramics for immobilization of Sr isotopes
(Elsevier, 2013)
A new technology for radionuclide trapping which is based on bio-templating approach was proposed in this paper. Porous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium ...
Influence of size scale and morphology on antibacterial properties of ZnO powders hydrothemally synthesized using different surface stabilizing agents
(Elsevier, 2013)
Metal oxide nanoparticles represent a new class of important materials that are increasingly being developed for use in research and health-related applications. Although the antibacterial activity and efficiency of bulk ...
Structural characterization and electrical properties of sintered magnesium–titanate ceramics
(Elsevier, 2013)
In this article the influence of ball miling process on structure of MgO–TiO2 system, as well as the electrical properties of samples after sintering, was investigated. The mixtures of MgO–TiO2 powders were mechanically ...
Kinetics of hydrogen absorption in Zr-based alloys
(Elsevier, 2013)
The kinetics of hydrogen absorption in Zr-based alloys Zr–2.5Nb, Zr–10Nb, Zr–2.5Nb–3Ta and Zr–10Nb–12Ta have been investigated in the temperature range 673–973 K at 1 bar hydrogen pressure. The improvement in hydrogen ...
Analysis and optimization of a thermal sensor system for measuring water flow
(Elsevier, 2013)
A simple thermal sensor system was designed for measuring water flow in the water mains using the heat loss principle with a NTC thick film segmented thermistor as a self-heating sensor. Thick film segmented thermistors ...
