The kinetics of the partial dehydration of gibbsite to activated alumina in a reactor for pneumatic transport / Kinetika parcijalne dehidratacije gibsita u reaktoru sa pneumatskim transportom
(Serbian Chemical Society, 2001)
The dehydration kinetics of gibbsite to activated alumina was investigated at four different temperatures between 883 K and 943 K in a reactor for pneumatic transport in the dilute two phase flow regime. The first order ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Serbian Chemical Society, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
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 ...
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.
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 ...
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 ...
Oscillatory chemical reaction as model system for the catalysts characterization / Oscilatorna hemijska reakcija kao modelni sistem za karakterizaciju katalizatora
(Društvo inženjera plastičara i gumara, Beograd, 2001)
The main kinetic characteristics of a catalyst could be obtained by examination of its behavior in some known reaction system, so-called model reaction system. The model reaction system is usually chosen to be as simple ...
The oscillatory Bray-Liebhafsky reaction as a matrix for analyzing enzyme and polymeric catalysts for hydrogen peroxide
(International Institute for the Science of Sintering, Beograd, 2001)
The Bray-Liebhafsky (BL) oscillatory reaction, as a reaction where hydrogen peroxide decomposes into the water and oxygen in the presence of iodate and hydrogen ions through a complex mechanism involving a number of ...
Low-molecular-weight protease inhibitors of microbial origin / Niskomolekulski inhibitori proteaza mikrobnog porekla
(Srpsko hemijsko društvo, Beograd, 2001)
We have witnessed an explosion of informations about properties, also mode of action and regulation of proteases from the metalloproteases at the cell surface to the AIDS protease. Protease inhibitors have a great importance ...
