Mechanochemical preparation and characterization of CaO·ZnO used as catalyst for biodiesel synthesis
(Elsevier, 2012)
In this study, the synthesis of biodiesel or fatty acid methyl esters (FAME) from sunflower oil and methanol using CaO·ZnO catalyst was investigated. Catalyst was synthesized by ball milling of Ca(OH)2 and ZnO powder mixture ...
The contribution of fractal nature to BaTiO3-ceramics microstructure analysis
(Elsevier, 2012)
The structure of BaTiO3 based materials can be controlled by using different technological parameters and different additives. In this paper, microstructure and dielectrical properties of Er2O3 doped BaTiO3-ceramics, ...
Processing Route to Fully Dense Nanostructured HAp Bioceramics: From Powder Synthesis to Sintering
(Hoboken, NJ : John Wiley & Sons, 2012)
The study is devoted to the processing of hydroxyapatite (HAp) nanopowder to develop fully dense nanostructured bioceramics by pressureless sintering. The sintering behavior of stoichiometric HAp prepared by hydrothermal ...
Fluctuations of the number of adsorbed molecules in biosensors due to stochastic adsorption–desorption processes coupled with mass transfer
(Elsevier, 2012)
We derived a simple theory of fluctuations of the equilibrium number of adsorbed molecules in biosensors, caused by the stochastic nature of adsorption–desorption (AD) processes coupled with mass transfer. The two-compartment ...
Poly(d,l-lactide-co-glycolide)/hydroxyapatite core–shell nanospheres. Part 4: A change of the surface properties during degradation process and the corresponding in vitro cellular response
(Elsevier, 2012)
The surface properties of PLGA/HAp core–shell nanoparticles loaded with clindamycin obtained by an ultrasonic processing method and their changes under the simulated physiological conditions during the degradation process ...
Apatite formation on nanomaterial calcium phosphate/poly-DL-lactide-co-glycolide in simulated body fluid
(Milano : Wichtig Publishing, 2012)
Simulated body fluid (SBF) is an artificial fluid which has ionic composition and ionic concentration similar to human blood plasma. Purpose: This paper compares the interaction between the nanomaterial containing calcium ...
Processing parameter influence on BaTiO3 ceramic fractal microstructure and dielectric characteristics
(Maney, 2012)
In the process of BaTiO3 ceramics consolidation, technological parameters like sintering temperature, pressing pressure and additives significantly determine the microstructure and electrical properties. Slight change of ...
Up-conversion luminescence in Ho3+ and Tm3+ co-doped Y2O3:Yb3+ fine powders obtained through aerosol decomposition
(Elsevier, 2012)
Fine yttrium oxide powders doped with Yb3+ and co-doped either with Tm3+ or Ho3+ were synthesized via spray pyrolysis at 900 °C using 0.1 M nitrate precursor. Synthesized powders were additionally thermally treated at 1100 ...
Pt supported on nano-tungsten carbide as a beneficial catalyst for the oxygen reduction reaction in alkaline solution
(Elsevier, 2012)
Platinum nanocatalyst at nano-tungsten carbide was synthesized, characterized and tested for oxygen reduction reaction (ORR) in 0.1 mol dm−3 NaOH, at 25 °C. Tungsten-carbide islands on nano-tungsten particles (WC) was ...
Copper-Sulfate Pentahydrate as a Product of the Waste Sulfuric Acid Solution Treatment
(Springer US, 2012)
The aim of this study is synthesis of copper-sulfate pentahydrate from the waste sulfuric acid solution-mother liquor generated during the regeneration process of copper bleed solution. Copper is removed from the mother ...
