Yb3+ doped dyphillosilicates prepared by thermally induced phase transformation of zeolites
(Russian Journal of Physical Chemistry A, 2007)
Yb3+-doped Ba and Sr diphyllosilicates (hexacelsians) have been synthesized using the Na form of LTA zeolite by ion-exchange procedure and thermal treatment. The crystal structures of both doped samples are refined and ...
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 ...
Artificial neural network data analysis for classification of soils based on their radionuclide content
(Russian Journal of Physical Chemistry A, 2007)
The artificial neural network (ANN) data analysis method was used to recognize and classify soils of an unknown geographic origin. A total of 103 soil samples were differentiated into classes according to the regions in ...
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 ...
Adjuvant antiproliferative and cytotoxic effect of aloin in irradiated HeLaS3 cells
(Russian Journal of Physical Chemistry A, 2007)
Naturally occurring phytoanthracycline, aloin, was used to radiosensitize HeLaS3 human cervix carcinoma cells. The results indicated that the cytotoxic adjuvant effect of aloin was synergistic with gammaionizing radiation ...
Chemical and radiochemical characterization of depleted uranium in contaminated soils
(Russian Journal of Physical Chemistry A, 2007)
The main results of chemical and radiochemical characterization and fractionation of depleted uranium in soils contaminated during the Balkan conflict in 1999 are presented in the paper. Alpha-spectrometric analysis of ...
A Comparison of Alkaline and Proton Exchange Membrane Electrolyzers
(Russian Journal of Physical Chemistry A, 2008)
Faraday efficiencies and energy consumptions of a small commercial proton exchange membrane (PEM) and an alkaline electrolyzer designed at our laboratory and equipped with different cathode materials were determined. Our ...
HTB140 melanoma cells under proton irradiation and/or alkylating agents
(Russian Journal of Physical Chemistry A, 2007)
Chemoresistance is a major problem in the treatment of malignant melanoma. The mainstay of treatment for melanoma is the DNA-alkylating agent dacarbazine (DTIC). Fotemustine (FM), a member of the chloroethylnitrosourea ...
Malathion-induced inhibition of human plasma cholinesterase studied by the fluorescence spectroscopy method
(Russian Journal of Physical Chemistry A, 2008)
The in vitro effect of technical grade malathion was assessed via the kinetic parameters of human plasma butyrylcholinesterase (BChE) using N-methylindoxyl acetate as a substrate for BChE. An inhibitor kinetics study ...
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 ...
