In vitro control of multiplication of some food-associated bacteria by thyme, rosemary and sage isolates
(Elsevier Sci Ltd, Oxford, 2012)
Antibacterial activity of thyme, rosemary and sage isolates obtained by supercritical fluid extraction and hydrodistillation was investigated on Geobacillus stearotermophillus, Bacillus cereus, Bacillus subtilis var. niger, ...
Increase in bioethanol production yield from triticale by simultaneous saccharification and fermentation with application of ultrasound
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: Bioethanol produced from renewable biomass, such as sugar, starch or lignocellulosic materials, is one of the alternative energy resources that is environmentally friendly. Triticale crops have a high yield as ...
Alginate hydrogel microbeads incorporated with Ag nanoparticles obtained by electrochemical method
(Elsevier Science Sa, Lausanne, 2012)
An innovative method was developed for production of alginate hydrogel microbeads incorporated with silver nanoparticles (AgNPs) based on electrochemical synthesis followed by electrostatic extrusion. AgNPs were synthesized ...
Modelling and optimization of supercritical CO2 extraction of St. John's Wort (Hypericum perforatum L.) using genetic algorithm
(Elsevier Science Bv, Amsterdam, 2012)
Modelling and optimization of the extraction of St. John's Wort using supercritical fluid is the subject of this study. Applying conservation of mass, two partial differential equations were written for solute concentration ...
Investigation of copper-alginate microbeads as antimicrobial materials for potential biomedical applications
(Wiley-Blackwell, Hoboken, 2012)
Influence of surface modified TiO2 nanoparticles by gallates on the properties of PMMA/TiO2 nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Nanocomposites based on poly(methyl methacrylate) (PMMA) and TiO2 nanoparticles were synthesized by in situ radical polymerization of MMA in solution. The surface of TiO2 nanoparticles was modified with four gallic acid ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Service life test of non-noble metal composite cathodes for hydrogen evolution in sodium hydroxide solution
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work polarization characteristics and "service life" test of the non-noble metal composite coatings Ni-MoOx and Ni-MoO2 for hydrogen evolution reaction (HER) in 32 wt.% NaOH at 90 degrees C were investigated and ...
Structure and luminescence properties of Eu3+ doped TiO2 nanocrystals and prolate nanospheroids synthesized by the hydrothermal processing
(Elsevier Sci Ltd, Oxford, 2012)
We report on a new approach to the synthesis of Eu3+ doped TiO2 nanocrystals and prolate nanospheroids. They were synthesized by shape transformation of hydrothermally treated titania nanotubes at different pH and in the ...
Structural and optical characterization of hemimorphite with flower-like morphology synthesized by a novel low-temperature method
(Materials Letters, 2012)
We report on novel, low temperature synthesis of well crystallized hemimorphite zinc silicate Zn4Si2O7(OH)(2)(H2O) (ZSO) with flower-like morphology, via one-pot method that includes the assistance of a non-ionic block ...
