Surface modifications of TiN coatings by a pulsed TEA CO2 laser: Coating thickness effects
(Russian Journal of Physical Chemistry A, 2007)
Interactions of a transversely excited atmospheric (TEA) CO2 laser, pulse duration similar to 2 mu s (initial spike FWHM similar to 120 ns), with polycrystalline titanium nitride (TiN) coatings deposited on high-quality ...
Optical properties of CdSe and CdSe/ZnS quantum dots dispersed in solvents of different polarity
(Russian Journal of Physical Chemistry A, 2009)
Original organic capping TOPO/TOP groups of CdSe and CdSe/ZnS quantum dots (QDs), from mother solution were replaced with 2_mercaptoethanol, which was chosen as model compound, in order to achieve water solubility. Obtained ...
Effects of acute gamma-irradiation on extracellular adenine nucleotide hydrolysis in developing rat brain
(Russian Journal of Physical Chemistry A, 2009)
Cell membrane is highly sensitive to irradiation which, acting directly or indirectly, may disturb functions of constitutive proteins including membrane enzymes. Plasma membrane surface-located enzyme chain of ecto-nucleotide ...
Effect of EDTA on copper-induced inhibition of rat myometrial ecto-ATPase activity
(Russian Journal of Physical Chemistry A, 2009)
The aim of this study was to examine in vitro chelators ability to prevent copper-induced inhibition of rat myometrial ecto-ATPase activity. The effects of increasing CuSO(4) concentrations, in the absence and presence of ...
Na+/K+-ATPase: Activity and inhibition
(Russian Journal of Physical Chemistry A, 2009)
The aim of the study was to give an overview of the mechanism of inhibition of Na+/K+-ATPase activity induced by some specific and non specific inhibitors. For this purpose, the effects of some ouabain like compounds ...
The influence of malathion and its decomposition products on free and immobilized acetylcholinesterase
(Russian Journal of Physical Chemistry A, 2008)
The influence of malathion and its four main degradation products found in irradiated solutions (malaoxon, isomalathion, diethyl maleate and O,O-dimethyl phosphate) on acetylcholinesterase (AChE) of free and immobilized ...
The reduction of hexanitrocobaltate(III) ion in the presence of hexadecyltrimethylammonium bromide
(Russian Journal of Physical Chemistry A, 2008)
The influence of cationic surfactant hexadecyltrimethylammonium bromide (CTAB) on the kinetics of the spontaneous reduction of the analytically important compound, sodium hexanitrocobaltate(III), was studied. The spontaneous ...
Antioxidant Enzymes Expression and Activity in Liver of Stressed Wistar Rat
(Russian Journal of Physical Chemistry A, 2009)
Altered activities of antioxidant defence system enzymes and the levels of free radicals scavengers have been found to correlate with various physiological or pathological conditions, including stress. The aim of this study ...
Micro- and nanosecond laser TiN coating/steel modification: Morphology studies
(Russian Journal of Physical Chemistry A, 2009)
Morphology effects induced during interaction of mu s- (Transversely Excited Atmospheric (TEA) CO(2) laser) or ns- (HF laser) pulses with titanium nitride (TiN) coating, deposited on austenitic stainless steel AISI 316, ...
Isotope effects on band intensities in the B I-2 (+)-X pound I-2 (+) pound system of GaO isotopomers
(Russian Journal of Physical Chemistry A, 2009)
Relative intensities of eight vibronic bands, belonging to the Delta upsilon = -2 sequence of the B I-2 (+) pound -X I-2 (+) pound electronic transition of four GaO isotopomers have been measured and interpreted in terms ...
