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 ...
3-Cyanopropylsiloxane-Bonded Silica Gel: Characteristics and Applications in Thin-Layer Chromatography
(Akademiai Kiado Rt, Budapest, 2015)
An overview of the adsorption characteristics of 3-cyanopropylsiloxane-bonded silica gel as a specific, moderately polar sorbent which can be used for separation of different classes of organic and inorganic substances in ...
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 ...
Sensitive Determination of the Indole Alkaloid Reserpine Using a Glassy Carbon Based Electrochemical Sensor
(Esg, Belgrade, 2015)
In the present paper a glassy carbon electrode was successfully applied for the sensitive and selective determination of the indole alkaloid reserpine by differential pulse voltammetry (DPV). The electrochemical behavior ...
Non-covalent Stabilization in Transition Metal Coordination and Organometallic Complexes
(Non-covalent Interactions in the Synthesis and Design of New Compounds, 2016)
Non-covalent interactions (NCIs) are ubiquitous in nature, and the demonstration of their role in transition metal chemistry remains a vivid domain of research. Indeed, a better understanding of the interplay of NCIs with ...
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 ...
5-Aryl-1H-pyrazole-3-carboxylic acids as selective inhibitors of human carbonic anhydrases IX and XII
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Inhibitory activity of a congeneric set of 23 phenyl-substituted 5-phenyl-pyrazole-3-carboxylic acids toward human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms I, II, IX and XII was evaluated by a stopped-flow CO2 hydrase ...
Biotransformation of 4-halophenols to 4-halocatechols using Escherichia coli expressing 4-hydroxyphenylacetate 3-hydroxylase
(Springer, New York, 2011)
Escherichia coli cells, expressing 4-hydroxyphenylacetate 3-hydroxylase, fully transformed 4-halogenated phenols to their equivalent catechols as single products in shaken flasks. 4-Fluorophenol was transformed at a rate ...
