LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Predictive modeling of the hypothalamic-pituitary-adrenal (HPA) function. dynamic systems theory approach by stoichiometric network analysis and quenching small amplitude oscillations
(International Journal of Nonlinear Sciences and Numerical Simulation, 2009)
Two methods for dynamic systems analysis, Stoichiometric Network Analysis (SNA) and Quenching of Small Amplitude Oscillations (QA), are used to study the behaviour of a vital biological system. Both methods use geometric ...
Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
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 ...
The chaotic sequences in the Bray-Liebhafsky reaction in an open reactor
(Royal Soc Chemistry, Cambridge, 2008)
Attractor reconstruction is done from the time series obtained by experimental investigation and by deterministic and stochastic simulation of the Bray-Liebhafsky oscillatory reaction. The appearance of deterministic chaos ...
Pyrolysis and Pt(IV)- and Ru(III)-ion catalyzed pyrolysis of asphaltenes in organic geochemical investigation of a biodegraded crude oil (Gaj, Serbia)
(Elsevier Sci Ltd, Oxford, 2009)
This paper is aimed at investigating the origin and geological history of the biodegraded Gaj (Serbia) crude oil, based on comparison of biomarkers, particularly alkylaromatics, in crude oil maltene fraction, with those ...
Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Springer Heidelberg, Heidelberg, 2007)
Introduction. In this work, sediments of the River Tisa (Tisza) are studied to assess their environmental pollution levels for some major heavy metals, as well as to predict the investigated elements' mobility on the basis ...
Ring-closing metathesis/fragmentation route to geometrically defined medium-ring cycloalkenes: Total synthesis of (+/-)-periplanone C
(American Chemical Society (ACS), 2004)
The combination of alkene metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium-ring cycloalkenes. The versatility of this method is demonstrated by the total synthesis of Periplanone C, a ...
Electrochemical and capacitive properties of thin-layer carbon black electrodes
(Journal of Power Sources, 2008)
Electrochemical properties and porous-structure-dependent capacitive ability of commercial carbon blacks, Black Pearls 2000® (BP) and Vulcan® XC 72R (XC), were investigated in H2SO4 solution by cyclic voltammetry (CV) and ...
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 ...
