Radiation synthesis, characterisation and antimicrobial application of novel copolymeric silver/poly(2-hydroxyethyl methacrylate/itaconic acid) nanocomposite hydrogels
(Polymer Bulletin, 2013)
Silver nanoparticles were fabricated via in situ reduction of silver nitrate embedded in swollen P(HEMA/IA) hydrogel, using gamma radiolysis method. Copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and ...
Properties of quenched LiFePO4/C powder obtained via cellulose matrix-assisted method
(Powder Technology, 2013)
In this study, nanocrystalline LiFePO4/C composite powder has been synthesized via a cellulose matrix-assisted method. In an experiment conducted under extreme conditions involving rapid heating, short high-temperature ...
Molecular structure of carboxymethyl starch in dilute aqueous sodium chloride solutions
(Wiley-VCH Verlag, 2013)
The dilute solution behavior of six carboxymethyl starch (CMS) samples was investigated in aqueous NaCl solutions of different concentration (0.01, 0.05, 0.1, and 0.5 M) by dynamic light scattering (DLS) at 25°C. The values ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In this work the hydrogen evolution reaction (HER) at Ni-Sn alloy coatings, deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) SnCl2 + 0.3 mol dm(-3) NiCl2 in the pyrophosphate-glycine ...
Mechanical and microstructural properties of the fly-ash-based geopolymer paste and mortar
(Institute of Metals and Technology, 2013)
In this paper we have investigated the influence of synthesis parameters on the mechanical properties of the fly-ash-based geopolymer paste and mortars. Moreover, the influence of an addition of limestone sand on the ...
Optimization of the production process through response surface method: Bricks made of loess
(Elsevier, 2013)
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
Influence of Alkali Cation on the Mechanical Properties and Durability of Fly Ash Based Geopolymers
(Slovenian Chemical Society, 2013)
This research has provided information about the influence of alkali cations (Na+ and K+) on the mechanical properties and durability of fly ash based geopolymers. The results have shown that alkali cations have a strong ...
Kinetic model of lipase-catalyzed conversion of ascorbic acid and oleic acid to liposoluble vitamin C ester
(Elsevier Science Sa, Lausanne, 2013)
The kinetics of L-ascorbyl oleate synthesis catalyzed by immobilized lipase from Candida antarctica in acetone was investigated. Significant inhibition of synthesis with an excess of ascorbic acid was observed. Experimental ...
Novel Pt catalyst on ruthenium doped TiO2 support for oxygen reduction reaction
(Elsevier B.V., 2013)
Ruthenium doped titanium oxide support was synthesized. The support was characterized by BET (Brunauer, Emmett, Teller) and X-ray diffraction techniques (XRD). Determined specific surface area was 41 m(2) g(-1). XRD revealed ...
Polymers based on renewable raw materials - Part II / Polimeri na bazi obnovljivih sirovina – II. dio
(Croatian Society of Chemical Engineers, 2013)
A short review of biopolymers based on starch (starch derivatives, thermoplastic starch), lignin and hemicelluloses, chitin (chitosan) and products obtained by degradation of starch and other polysaccharides and sugars ...
