Oxygen reduction reaction on spontaneously and potentiodynamically formed Au/TiO2 composite surfaces
(Elsevier, 2007)
From aqueous solutions, gold was deposited on freshly polished titanium surface either by displacement reaction or by potentiodynamic polarization. Both of these procedures resulted in the formation of Au/TiO2 composite ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Elsevier, 2007)
The adsorption mechanisms of Pb2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge, pHpzc, is 7.4 ± 0.1 for ...
The influence of zinc surface pretreatment on the adhesion of epoxy coating electrodeposited on hot-dip galvanized steel
(Elsevier, 2007)
The adhesion and electrochemical properties of epoxy coatings electrodeposited on hot-dip galvanized steel with and without passive films were investigated during exposure to 3% NaCl. The passive films were formed in hot ...
In situ influence of coal ash dump on the quality of neighboring surface and ground waters by applying correlation statistic analysis
(Elsevier, 2007)
The aim of this study was to establish the real in situ influence of coal ash and slag transport and storage on the quality of neighboring surface and ground waters by applying correlation statistic analysis. It was found ...
Regioselective synthesis of 1,3-thiazines by sequential 4-oxothiazolidine to 1,2-dithiole to 1,3-thiazine transformations: role of intramolecular non-bonded S/O interactions
(Elsevier, 2007)
A new synthetic approach to 2,3-dihydro-4H-1,3-thiazine derivatives based upon reductive rearrangement of 1,2-dithiole-3-ylidene thiones has been developed. In turn, the 1,2-dithiole derivatives were prepared by an efficient ...
Platinum(II) complexes with l-methionylglycine and l-methionyl-l-leucine ligands: Synthesis, characterization and in vitro antitumoral activity
(Elsevier, 2007)
Four dipeptide complexes of the type [PtX2(dipeptide)] · H2O (X = Cl, I, dipeptide = l-methionylglycine, l-methionyl-l-leucine) were prepared. The complexes were characterized by 1H, 13C, 195Pt NMR and infrared spectroscopy, ...
Two distinct manganese(II) complexes with hexadentate 1,3-propanediaminetetraacetate ligand: The ability of metal(II) complexes with 1,3-pdta ligand to form solid solutions
(Elsevier, 2007)
The ability of Mn(II) ion to form two distinctly different complexes with 1,3-propanediaminetetraacetate (1,3-pdta) ligand has been demonstrated by performing X-ray analyses of their crystalline Mg(II) salts. The two types ...

Dexamethasone treatment affects nuclear glucocorticoid receptor and glucocorticoid response element binding activity in liver of rats (Rattus norvegicus) during aging
(Elsevier, 2007)
Aging is associated with marked changes in the biochemical processes of many organs. Basal and glucocorticoid induced of liver nuclear glucocorticoid receptor (GR) on the level of protein expression and DNA-binding activity ...
Morphology and growth of electrodeposited silver powder particles
(Elsevier, 2007)
The effect of overpotential pulsing and periodic current reversal on the morphology of silver powders was investigated using a scanning electron microscope (SEM). It is shown that the profile of pulses or current reversal ...
