Diagenetic relationships between sulphur species and formation of pyrite in coals and sediments
(Taylor & Francis Inc, Philadelphia, 2007)
Based on the abundant minerals in a Miocene freshwater sequence of mixed sediments (pieces of coal in clays, sand-stones and shales) alternating with coal layers, the following main sedimentation environments were ...
Determination of glass temperature of polymers by inverse gas chromatography
(Elsevier, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
In situ STM imaging of spontaneously deposited ruthenium on Au(111)
(Elsevier, 2002)
Spontaneous deposition of ruthenium on Au(1 1 1) surfaces from 1.0 mM RuCl3 + 0.5 M H2SO4 (or 0.1 M HClO4) solutions was investigated by in situ STM and cyclic voltammetry, focusing on the morphology of the resulting ...
Bacterially generated Fe2(SO4)3 from pyrite, as a leaching agent for heavy metals from lignite ash / Bakterijski generisani Fe2(SO4)3 iz pirita kao agens za luženje elektrofilterskog pepela termoelektrane iz procesa sagorevanja lignita
(Serbian Chemical Society, 2007)
Investigations of heavy metals from lignite ash, which is a coal combustion by-product, have for years been very interesting from different aspects of environmental protection. In this study, the possibility of microbiological ...
Structures of Ni - Ni Nan contacts obtained by the electrode position in the presence of a magnetic field / Struktura nikal - nikal nanokontakta dobijenih elektrohemijskim taloženjem
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
Structures of Ni - Ni Nan contacts obtained by the electrode position at the different cathodic potentials were analyzed. Ni - Ni Nan contacts were electrodeposited from a Watt solution in the presence of coumarone, and ...
Surface resistivity estimation by scanning surface potential microscopy
(AIP Publishing, 2008)
Nickel was sputter deposited on a glass with a thin film thickness of 600 nm under either in an argon atmosphere or under a partial pressure of nitrogen of either 1.3× 10-4 or 4× 10-4 mbar. Atomic force microscopy and ...
Corrosion of chromium white cast iron in acidic medium / Korozija visokohromnog belog gvožđa u kiseloj sredini
(Belgrade, Serbia : Engineering Society for Corrosion, 2008)
In this work we studied the electrochemical behavior of chromium white cast irons in deaerated aqueous sulphuric acid solutions of the pH 1-3. The measurements of concentrations of dissolved iron and chromium in the solution, ...
Phenomenology of a formation of a honeycomb-like structure during copper electrodeposition
(Journal of Solid State Electrochemistry, 2007)
In this paper, the phenomenology of a formation of a honeycomb-like structure was considered. Copper deposits obtained at overpotential of 1000 mV were examined by scanning electron microscopy (SEM) technique. It was shown ...
Analysis of transient adsorption processes using micro/nanocantilever oscillators
(Elsevier, 2008)
We analyzed the transient in micro/nanocantilever response which begins when adsorption-desorption process starts on the surface of an oscillating cantilever. By solving a differential equation which describes the oscillation ...
Electrochemical examination of mixed-ligand cobalt(III) complexes with tetraazamacrocyclic ligand and heterocyclic dithiocarbamates
(Wiley-VCH Verlag GmbH, 2001)
Electrochemical stability of eight complexes of the general formula [co 111 Rdtc(1-8)cyclam](ClO 4 ) 2 , where cyclam=1,4,8,11-tetraazacyclotetradecane and Rdtc - (1-8)=4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), ...
