Electrochemical oxidation of iodide in aqueous solution
(Elsevier Science Sa, Lausanne, 2006)
Electrochemical oxidation of iodide on DSA (Ti/RuO2) anode was investigated in laboratory cell and semi-industrial electrochemical reactor. Anodic polarization curves in the laboratory cell were obtained in solutions ...
The thermal degradation of poly(diethyl fumarate)
(Elsevier Sci Ltd, Oxford, 2006)
The kinetics and mechanism of the thermal degradation of poly(diethyl fumarate) (PDEF) were studied by thermogravimetry, as well as by analysis of the thermolysis volatiles and polymer residue. The characteristic mass loss ...
Oak acorn, polyphenols and antioxidant activity in functional food
(Elsevier Sci Ltd, Oxford, 2006)
In this paper, are presented the results of physical and chemical investigations of differently treated samples of oak acorn. The aim of this investigation is to estimate the influence of thermal treatment on physical and ...
Kinetics of the mild steel corrosion protection by polypyrrole-oxalate coating in sulfuric acid solution
(Elsevier Science Sa, Lausanne, 2006)
Kinetics of the mild steel corrosion protection in 0.1 mol dm(-3) H2SO4 by polypyrrole coatings have been investigated by the means of electrochemical impedance spectroscopy (EIS), cyclic voltammetry, polarization measurements ...
The synthesis of ultrafine and nanocomposite powders based on copper, silver anal alumina
(Kovove Materialy, 2006)
Contemporary materials with predetermined properties can be successfully synthesized by utilizing the principles of hydrometallurgy and powder metallurgy. The results of developing a new procedure for the synthesis of ...
Fast estimation of quasi-steady states of cyclic nonlinear processes based on higher-order frequency response functions. Case study: Cyclic operation of an adsorption column
(Amer Chemical Soc, Washington, 2006)
A new method for fast approximate calculation of quasi-steady states of cyclic processes is presented. The method is based on the concept of higher-order frequency response functions. The system input is represented in the ...
Cardiac tissue engineering: effects of bioreactor flow environment on tissue constructs
(Wiley, Hoboken, 2006)
The limited ability of cardiac muscle to regenerate after injury and the small number of organs available for transplantation motivate studies aimed at curative treatment options. Tissue engineering based on the integrated ...
The mathematical model of insulin desorption from the bioactive, fibrous artificial store
(Wiley-Liss, Hoboken, 2006)
The aim of this study was to study insulin desorption from fibrous insulin artificial store in vitro as well as in vivo, with the intention to define a mathematical model that would describe this process. Release profile ...
Prediction of programmed-temperature retention indices of polycyclic aromatic hydrocarbons in the Lee index scale by artificial neural network
(Univerzitet u Kragujevcu - Prirodno-matematički fakultet, Kragujevac, 2006)
A feed-forward artificial neural network (ANN) model was used to predict the programmed-temperature retention indices RIs in the Lee index scale of polycyclic aromatic hydrocarbons (PAHs). The data used in this paper include ...
Substituent and solvent effects on the UV/vis absorption spectra of 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-eyano-2-pyridones
(Elsevier Science Bv, Amsterdam, 2006)
Absorption spectra of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones have been recorded in 12 protic and aprotic solvents in the range 200-600 nm. The effects of substituents on the absorption ...
