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 ...
High Activity and Stability of Pt2Bi Catalyst in Formic Acid Oxidation
(Springer, New York, 2012)
Formic acid oxidation was studied on a new prepared Pt2Bi characterized by X-ray diffraction spectroscopy (phase composition), scanning tunneling microscopy (STM) (surface morphology), and COads stripping voltammetry ...
Atomic partial charges for mixed chloroammine chromium(III) complexes fitted to the molecular electrostatic potential
(Elsevier, 2012)
Using the RESP procedure partial atomic charges for six isomers of a series of octahedral complexes [Cr(NH3)(6-x)(Cl)(x)]((3-x)+) (x = 0, 1, 2, 3) were least-square fitted to the molecular electrostatic potential (MEP) ...
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 ...
Preparation of combined extract of cell wall and cytosol antigens of Candida albicans for immunoblot analysis
(Journal of Clinical Laboratory Analysis, 2007)
Immunoblot analysis is not in wide use for diagnosis of invasive candidiasis, mostly because the procedure is not standardized and hence not reliable. This work describes a standardized method for C. albicans antigen extract ...
N-type silicon electron mobility and its relationship to the kink effect for nano-scaled SOI NMOS devices
(Materials Science Forum, 2007)
Electron mobility for the silicon-based devices is one of the most important parameters, which determine the behavior of components. Mobility depends on silicon purity, doping level, presence of lattice defects and electric ...
Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Materials Science Forum, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
P-nitrophenol electro-oxidation on a btma(+)-bentonite-modified electrode
(Clay Minerals Soc, Chantilly, 2012)
Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, ...
High Levan Production by Bacillus licheniformis NS032 Using Ammonium Chloride as the Sole Nitrogen Source
(Humana Press Inc, Totowa, 2015)
In this study, levan production by Bacillus licheniformis NS032 isolated from a petroleum sludge sample was investigated. High levan yield was obtained in a wide range of sucrose concentrations (up to 400 g/L) and, contrary ...
Surface properties of the Ni-silica gel catalyst precursors for the vegetable oil hydrogenation process: N-2 sorption and XPS studies
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The effect of the type of the silica gel pore structure on the surface properties of the Ni-silica gel catalyst precursors for the vegetable oil hydrogenation process has been examined applying N-2 sorption and X-ray ...
