Glassy carbon electrodes: II. Modification by immersion in AgNO 3
(Elsevier, 2001)
The modification of glassy carbon by immersion in AgNO 3 solution was studied by cyclic voltammetry, vacuum techniques (AES and XPS) and STM. The influence of Ag + concentration, time of immersion, the presence of oxygen ...
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 ...
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.
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 ...
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 ...
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 ...
Decomposition of N2O over catalyst cu-ZSM-5: Analysis of reaction model / Razlaganje N2O na katalizatoru Cu-ZSM-5 - analiza modela reakcije
(Nauka, tehnika, bezbednost, 2001)
The model of mechanism of the nitrous oxide (N2O) decomposition over the catalyst Cu-ZSM-5 proposed in 1999 in the article of Ochs and Turek, is adapted for mentioned process in open reactor and analyzed by the stoichiometric ...
The electrocatalytic properties of the oxides of noble metals in the electrooxidation of methanol and formic acid
(Elsevier, 2001)
The electrooxidation of 0.25 M methanol as well as of 0.25 M formic acid was examined on oxides formed on the Au(111) electrode surface in 0.5 M H2SO4 and 0.5 M NaHCO3 at a sweep rate of 0.5 mV/s. In the case of methanol, ...
