Glassy carbon electrodes: I. Characterization and electrochemical activation
(Elsevier, 2001)
Electrochemical properties of glassy carbon electrodes of two types were examined, one thermally treated at 1000°C (sample K) and another thermally treated at 2500° (sample G). Mechanically polished or electrochemically ...
Maturity assessment of oils from the Sakhalin oil fields in Russia: Phenanthrene content as a tool
(Elsevier, 2001)
A correlation analysis of maturation parameters was carried out on 14 crude oil samples from nine oil fields on Sakhalin Island (Russia). The oils were taken from reservoir rocks of Miocene age at depths ranging from 73 ...
The structure, growth and reactivity of electrodeposited Ru/Au(111) surfaces
(Elsevier, 2001)
In order to elucidate electronic effects on the oxidation of CO on small Ru clusters, we investigated this reaction on well defined Ru/Au(111) model systems via parallel in-situ STM studies of the structure and electrochemical ...
Alkylation of carbonyl compounds in the TiCl4-promoted reaction of trimethylsilyl enol ethers with epoxides
(Oxford : Pergamon-Elsevier Science Ltd, 2001)
Titanium tetrachloride promoted reaction of trimethylsilyl enol ethers with ethylene oxide affords homoaldol type products in moderate/good yields. Monosubstituted epoxides react regioselectively: the nucleophilic attack ...
1-D microstrip PBG filters without etching in the ground plane and with sinusoidal variation of the characteristic impedance
(IEEE Computer Society, 2001)
In this paper new types of (1-D) microstrip photonic band-gap (PBG) filters are presented. They have sinusoidal variation of the characteristic impedance in function of the length along the microstrip line. They are, also, ...
The effect of diffusion on the impulse response of RCE detector
(IEEE Photonics Technology Letters, 2001)
We present a theory which demonstrates how the diffusion of photogenerated carriers affects the impulse response of a resonant-cavity enhanced photodetector (RCE). Analytic expressions for carrier densities and short-circuit ...
Investigation of mixed D(2)/5-HT(1A) activity of N-heteroarylmethyl-N-phenylpiperazines, N-heteroarylethyl-N-phenylpiperazines and N-heteroarylpropyl-N-phenylpiperazines
(Govi-Verlag Pharmazeutischer Verlag Gmbh, Eschborn, 2001)
Eight novel N-heteroarylalkyl-N-phenylpiperazines have been synthesized, chemically characterized and evaluated for in vitro binding affinity at the dopamine and serotonin receptors. Synaptosomal membranes of fresh bovine ...
Parthenolide from the aerial parts of Tanacetum larvatum
(Oxford : Pergamon-Elsevier Science Ltd, 2001)
The genus Tanacetum L. comprises ca 150 species that commonly occur in Europe from the Mediterranean to Persia. Tanacetum larvatum (Gris.) Kanitz, the examination of which is reported, is distributed on elevated rocky ...
Introduction of a methyl group in alpha- or beta-position of 1-heteroarylethyl-4-phenyl-piperazines affects their dopaminergic/serotonergic properties
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
1-(2-Heteroarylalkyl)-4-phenylpiperazines containing methyl group in either the alpha- or the beta-position of the side alkyl chain were synthesized as racemic mixtures. They were evaluated for in vitro binding affinity ...
Electrochemical activation of the electroless deposition of Ni–P alloy and phase structure characterization of the deposit Part II: Single bath system
(Springer, 2001)
The process of electroless Ni plating (EP) was activated by the cathodic deposition of precursors of Ni in the same bath in which EP takes place. The current density (c.d.), duration of cathodic activation, as well as the ...
