Prediction of thermal shock behavior of alumina based refractories: Temperature difference, fracture resistance parameters and water quench
(Trans Tech Publications Ltd, Durnten-Zurich, 2001)
In this paper temperature difference and fracture resistance parameters were used for prediction of thermal shock behavior of the samples. Materials were alumina based commercial refractories with different content of Al2O3 ...
Material properties and thermal shock behavior of alumina based refractories
(Belgian Ceramic Soc, Mons, 2001)
Materials were five alumina based commercial refractories with different contents of ( Al2O3 + TiO2) from 28 % to 78 %. Thermal and mechanical properties of the chosen materials, were measured using standard laboratory ...
Shrinkage properties of peroxide-enzyme-biopolymer treated wool
(Sage Publications Ltd, London, 2001)
Incorporating an enzyme in the alkaline peroxide treatment bath enhances wool wettability and the effectiveness of subsequently applied chitosan biopolymer. Wool whiteness is also significantly enhanced. Wool knitted fabric ...
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 ...
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 ...
