Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...
Tetrahydrofuran-type sesquiterpenes from Artemisia lobelii All. var. canescens (DC.) Briqu. and Artemisia lobelii All. var. biasolettiana (Vis.) K. Maly
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Electrostatic surface potential calculation on several new halogenated benzimidazole-like dopaminergic ligands
(Wiley-VCH Verlag, 2004)
We examined the effects of the electron density distribution (electrostatic surface potential; ESP) of several new benzimidazole-type ligands on their binding affinity for the D 1 and D 2 dopamine receptors (DAR). Receptors ...
Modeling of the D2 dopamine receptor arylpiperazine binding site for 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}-4-arylpiperazines
(Wiley-VCH Verlag, 2004)
Docking of several 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}-4- and 1-benzylarylpiperazines to the D 2 dopamine receptor (DAR) was examined. The binding pocket of the D 2 DAR defined according to Teeter and DuRand [1] was ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni þ WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)
from a commercially available Watts bath containing additives for brightness and smoothing and insoluble ...
Conformational analysis of guaianolide-type sesquiterpene lactones by low-temperature NMR spectroscopy and semiempirical calculations
(Kluwer Academic/Plenum Publ, New York, 2004)
Conformational analysis of 9alpha-acetoxycumambrine A 1 and 8-O-isobutiryl-9alpha-acetoxycumambrine B 2 was carried out by low-temperature NMR studies. Results suggested that lactones 1 and 2 are mixtures of two distinctive ...
The effect of the structure of mixed tetraoxanes on their chromatographic behavior on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2004)
The retention behavior of 29 biologically active compounds, mixed 1,2,4,5-tetraoxanes, has been investigated by thin-layer chromatography on unmodified silica, CN-silica, and RP-18-silica. The binary mobile phases ethyl ...
Thermal diffusivity of NTC lasers obtained by photoacoustic technique
(Emerald, 2004)
The thermal diffusivity of thick film NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) technique. The powder mixture was composed of MnO (60 percent), CoO (32 ...
Dimethyldichlorosilane Hydrolysate as a Substitute for Cyclic Monomers in the Preparation of Functional Poly(siloxane)s
(Trans Tech Publications Ltd., 2004)
A number of carboxypropyl- terminated poly(siloxane)s were prepared using equilibration
polymerization reactions. Dimethyldichlorosilane hydrolysate, DDSH, was applied as a substitute
for the otherwise used cyclic siloxane ...
Introduction of Pt and Pd Nanoclusters in Zeolite Cavities by Thermal Degradation of Acetylacetonates
(Trans Tech Publications, Switzerland, 2004)
Nanodispersed metallic clusters of platinum and palladium were incorporated into NaX
zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates, solvent
evaporation and acetylacetonate ...
