Influence of amine activators and reaction parameters on grafting reaction between polystyrene and starch
(Springer, Dordrecht, 2014)
Polystyrene graft corn starch copolymers (PS-g-starch) were synthesized by emulsion polymerization using sodium dodecylsulfate (SDS) as the emulsifier and potassium persulfate (PPS) as the initiator. Influences of temperature ...
Cloning, Heterologous Expression, Purification and Characterization of M12 Mutant of Aspergillus niger Glucose Oxidase in Yeast Pichia pastoris KM71H
(Humana Press Inc, Totowa, 2014)
Aspergillus niger glucose oxidase (GOx) genes for wild-type (GenBank accession no. X16061, swiss-Prot; P13006) and M12 mutant (N2Y, K13E, T30 V, I94 V, K152R) were cloned into pPICZ alpha A vector for expression in Pichia ...
Wear Resistance and Dynamic Fracture Toughness of Hypoeutectic High-Chromium White Cast Iron Alloyed with Niobium and Vanadium
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2014)
The influence of mass fractions 1.5 % Nb and 1.5 % V, added singly and in combination, on the microstructural characteristics and properties relevant to the service performance of the hypoeutectic high-chromium white iron ...
Investigation of sorbents synthesised by mechanical-chemical reaction for sorption of As(III) and As(V) from aqueous medium
(Springer, New York, 2014)
Efficiency of Fe2O3 and mixture of Fe2O3 and MnO2 nanoparticles synthesised by mechanical-chemical reaction for inorganic As(III) and As(V) sorption was examined. Sorbents (Fe2O3 and mixture Fe2O3:MnO2 = 3:1) synthesised ...
Boron-doped diamond electrochemical sensor for sensitive determination of nicotine in tobacco products and anti-smoking pharmaceuticals
(Elsevier Science Sa, Lausanne, 2014)
A sensitive, selective and reliable electrochemical method for the determination of nicotine using differential pulse voltammetry on a bare boron-doped diamond electrode has been developed. Nicotine yielded a single oxidation ...
Recycling of silver-plated brass for production of high purity copper and ultrafine silver powder for electric contacts
(Bulgarian Acad Science, Sofia, 2014)
The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining materials of higher value ...
Pattern recognition methods and multivariate image analysis in HPTLC fingerprinting of propolis extracts
(Wiley-Blackwell, Hoboken, 2014)
High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting and classification of 52 propolis samples collected from Serbia and one sample ...
Experimental and theoretical investigations of the self-association of oxaliplatin
(Royal Soc Chemistry, Cambridge, 2014)
Self-aggregation in water of anti-cancer agents such as oxaliplatin (1) or its palladium-containing parent (2) is suspected to be the main reason for the exceptional resistance of concentrated infusions of these complexes ...
Comparative Electrochemical Determination of Total Antioxidant Activity in Infant Formula with Breast Milk
(Springer, New York, 2014)
The aim of this study is to investigate the significance of breast milk and infant formula in the prevention of oxidative stress, by electrochemical determination of the total antioxidant potential, demonstrating the ...
Lipophilicity Assessment of Ruthenium(II)-Arene Complexes by the Means of Reversed-Phase Thin-Layer Chromatography and DFT Calculations
(Hindawi Publishing Corporation, New York, 2014)
The lipophilicity of ten ruthenium(II)-arene complexes was assessed by reversed-phase thin-layer chromatography (RP-TLC) on octadecyl silica stationary phase. The binary solvent systems composed of water and acetonitrile ...
