A novel method for production of PVA-based microfibers by freezing/thawing cycles in hydrophilic settings
(Wiley-Blackwell, Hoboken, 2014)
Trace analysis of selected hormones and sterols in river sediments by liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry
(Elsevier, Amsterdam, 2014)
In this paper, development and optimization of new LC-MS method for determination of twenty selected hormones, human/animal and plant sterols in river sediments were described. Sediment samples were prepared using ultrasonic ...
Heat transfer between a packed bed and a larger immersed spherical particle
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this paper, heat transfer coefficients between the hot packed beds of particles and the larger cold immersed sphere were experimentally determined. The packed beds consisted of mono-sized spherical glass particles of ...

In situ photoreduction of Ag+-ions by TiO2 nanoparticles deposited on cotton and cotton/PET fabrics
(Springer, Dordrecht, 2014)
The possibility of in situ photoreduction of Ag+-ions using TiO2 nanoparticles deposited on cotton and cotton/PET fabrics in the presence of amino acid alanine and methyl alcohol has been discussed. The possible interaction ...
Preparation, characterization and mechanical properties of Bi12SiO20-PMMA composite films
(Elsevier Science Sa, Lausanne, 2014)
This paper investigates processing and characterization of polymer composite material PMMA-Bi12SiO20 (BSO). Thin films of pure PMMA and composites with 0.5 and 1.0 wt% of Bi12SiO20 powder were made using solution casting ...
Sol-gel synthesis and characterization of iron doped mullite
(Elsevier Science Sa, Lausanne, 2014)
Amorphous powders of iron doped 3:2 mullite (3Al(2)O(3)center dot 2SiO(2)) were prepared by sol-gel combustion process using ethanol-water solutions of Al(III) nitrate, Fe(III) nitrate, TEOS and urea. Compositions up to ...
A comprehensive approach to in vitro functional evaluation of Ag/alginate nanocomposite hydrogels
(Elsevier Sci Ltd, Oxford, 2014)
In this work, we present a comprehensive approach to evaluation of alginate microbeads with included silver nanoparticles (AgNPs) at the concentration range of 0.3-5 mM for potential biomedical use by combining cytotoxicity, ...
Review of biodiesel synthesis from waste oil under elevated pressure and temperature: Phase equilibrium, reaction kinetics, process design and techno-economic study
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The synthesis of biodiesel under elevated pressure and temperature could be promising technology which could result in sustainable biodiesel production, from renewable and waste streams like waste oil or used frying oil, ...
