Metal | polypyrrole battery with the air regenerated positive electrode
(Elsevier Science Bv, Amsterdam, 2014)
Recharge characteristics of the battery based on the electrochemically synthesized polypyrrole cathode and aluminum, zinc, or magnesium anode in 2 M NH4Cl are investigated. It is shown that polypyrrole electrode can be ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
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 ...

ZnO-modified cellulose fiber sheets for antibody immobilization
(Elsevier Sci Ltd, Oxford, 2014)
Cellulose fiber sheets impregnated with saccharide capped-ZnO nanoparticles were used as bioactive materials for antibody immobilization. First, ZnO nanoparticles were synthesized in the presence of glucose (monosaccharide), ...
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 ...
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, ...
