Chemical composition and antimicrobial activity of essential oil of physocaulis nodosus (L.) W.D.J.Koch
(Journal of Essential Oil Research, 2009)
Aerial parts of Physocaulis nodosus (L.) W.D.J.Koch. (Apiaceae) collected on Hajla mountain possessed an essential oil in 0.62% yield (expressed in g per 100 g of dried plant material). The oil was analyzed by GC and GC/MS. ...
Terrorism in the light of nonlinear sciences: Stoichiometric network analysis of the population processes / Terorizam u svetlu nelinearnih nauka - stehiometrijska mrežna analiza populacionih procesa
(Nauka, tehnika, bezbednost, 2003)
Terrorism is considered as a complex nonequilibrium dynamical system, and it is described with simple model. The model is tested by Stoichiometric Network Analysis. Stability/instability condition is determined. Dynamical ...
Nanocomposite permanent magnetic materials Nd-Fe-B type: The influence of nanocomposite on magnetic properties
(Technical Faculty, Bor, 2005)
The influence on the magnetic properties of nanocristalline ribbons and powders has character of microstructure, between others – the grain size volume of hard and soft magnetic phases and their distribution. Magnetic ...
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 ...
Modeling of coating optical fibers with polymer-magnetic powder composite coating
(International Institute for the Science of Sintering, Beograd, 2002)
A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological ...
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 ...
Malonic acid concentration as a control parameter in the kinetic analysis of the Belousov-Zhabotinsky reaction under batch conditions
(Royal Soc Chemistry, Cambridge, 2008)
The influence of the initial malonic acid concentration [MA](0) (8.00 x 10(-3) LT = [MA](0) LT = 4.30 x 10(-2) mol dm(-3)) in the presence of bromate (6.20 x 10(-2) mol dm(-3)), bromide (1.50 x 10(-5) mol dm(-3)), sulfuric ...
Characterization of the catalysts by means of an oscillatory reaction
(CRC Press, 2005)
One of the most known physical chemists Wilhelm Ostwald defined catalyst as a substance that participates in a particular chemical reaction and thereby increases its rate but without a net change in the amount of that ...
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 ...
