On the aqueous oxidation of polymetallic Cu-Zn-Pb gold-bearing sulphide ore in an autoclave
(CIM Bulletin, 2001)
The paper presents a study on the oxidation of polymetallic gold ore by oxygen in an autoclave. It presents optimum parameters of autoclave leaching of sulphide refractory ore in self-generated sulphuric acid solutions ...
The thermal degradation of poly(diethyl fumarate) / Termička degradacija poli(dietil fumarata)
(Association of Chemical Engineers of Serbia, 2001)
The kinetics and mechanism of the thermal degradation of poly(diethyl tumarate) (PDEF) were studied by thermogravimetry and analysis of the polymer residue. The characteristic mass loss temperatures were determined, as ...
Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...

On the kinetics of the hydrogen evolution reaction on nickel in alkaline solution - Part I. The mechanism
(Elsevier S.A., 2001)
The mechanism and kinetics of the hydrogen evolution reaction (her) were studied in 1.0 mol dm(-3) NaOH at 393.0 K. It was found that a combination of classical steady-state voltammetry and impedance spectroscopy can help ...
Phase-transformation kinetics in triphasic cordierite gel
(Cambridge Univ Press, New York, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
Electrostatic generation of alginate microbeads loaded with brewing yeast
(Elsevier Sci Ltd, Oxford, 2001)
The substantial concern with the possible use of immobilized yeast cells for beer production is reduction of internal mass transfer resistance during continuous fermentation. One way to minimise this problem is to use ...
Nonlinear frequency response of nonisothermal adsorption systems
(Springer, Dordrecht, 2001)
A general method for the investigation of adsorption kinetics of nonlinear, nonisothermal systems, based on frequency response analysis, is presented. It is based on the definition of higher-order frequency response functions ...
Integration of engineered cartilage
(Elsevier Sci Ltd, Oxford, 2001)
The structure and function of cartilaginous constructs, engineered in vitro using bovine articular chondrocytes, biodegradable scaffolds and bioreactors, can be modulated by the conditions and duration of tissue cultivation. ...
Dynamic mechanical analysis study of the curing of phenol-formaldehyde novolac resins
(Wiley, Hoboken, 2001)
The curing reaction of typical commercial phenol-formaldehyde novolac resins with hexamethylentetraamine (HMTA) was followed by dynamic mechanical analysis. The evolution of the rheological parameters, such as storage ...
