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 ...
Synthesis and structural characterization of the Co(III) complex with 2 '-[1-(2-pyridinyl)-ethylidene]oxamohydrazide (Hapsox): The crystal structure of bis-{2 '-[1-(2-pyridinyl)-ethylidene]-oxamohydrazido} cobalt(III) perchlorate, [Co(apsox)(2)]ClO4
(Taylor & Francis Ltd, Abingdon, 2003)
The synthesis of a novel ligand 2'-[1-(2-pyridinyl)-ethylidene]-oxamohydrazide (Hapsox), from a series of 2-acetylpyridine acylhydrazones, and its complex with Co(III), which is the first in this series of complexes are ...
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 ...
Determination of pyridoxine (vitamin B-6) in pharmaceuticals and urine samples using unmodified boron-doped diamond electrode
(Elsevier Science Sa, Lausanne, 2016)
Pyridoxine (vitamin B-6, VB6) was detected in pharmaceutical preparation and human urine samples by employing differential pulse voltammetry (DPV) at unmodified boron doped electrode. In Britton-Robinson buffer solution ...
Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer Japan, 2019)
Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Coordination and redox interactions of β-lactam antibiotics with Cu2+ in physiological settings and the impact on antibacterial activity
(Elsevier, 2018)
An increase in the copper pool in body fluids has been related to a number of pathological conditions, including infections. Copper ions may affect antibiotics via the formation of coordination bonds and/or redox reactions. ...
