The influence of the oxygen-containing species on the electrooxidation of the C1 – C4 alcohols at some platinum single crystal surfaces in alkaline solution
(Elsevier, 2001)
The electrochemical oxidation of methanol, ethanol, n-propanol and n-butanol has been carried out at the Pt(111) and the stepped Pt(755) and Pt(332) surfaces in sodium hydroxide solution. Special attention was paid to the ...
Antenna solution for future communication devices in mm-wave range
(IEEE Computer Society, 2001)
Different types of printed antennas for millimeter ranges such as high gain (narrow beam) with linear and circular polarization, sector antennas with azimuth angle of 60°, 90° and 180°, and omnidirectional antennas are ...
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 ...
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 ...
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 ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Broadband printed high gain antenna with wide angle radiation in azimuth
(IEEE Antennas and Propagation Society, AP-S International Symposium (Digest), 2001)
New broadband printed antenna concept is proposed, able to ensure very high operation bandwidth by simultaneously providing high gain and wide angle coverage in azimuth plane. Typical possible application scenarios are ...
1-D microstrip PBG band-pass filter without etching in the ground plane and with sinusoidal variation of the characteristic impedance
(IEEE Computer Society, 2001)
In this paper a new type of band-pass filter based on (1-D) microstrip photonic band-gap (PBG) is presented. The band-pass filter is a serial connection of two periodic structures with sinusoidal variation of the characteristic ...
Stoichiometric network analysis of autocatalator / Stehiometrijska mrežna analiza autokatalatora
(Nauka, tehnika, bezbednost, 2001)
Stoichiometric network analysis is applied on the autocatalator, the model of the oscillatory chemical reactions. Particularly simple stability condition is evaluated, without approximations.
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, ...
