Fractal approach to ac impedance spectroscopy studies of ceramic materials
(Kluwer Academic Publ, Dordrecht, 2001)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Computational studies in the AlPO4-34 system
(Kluwer Academic Publ, Dordrecht, 2001)
The lattice energies of the as-synthesized fluoride-containing chabazite-like aluminophosphate (AlPO4-34F) and of the corresponding metal-substituted materials [MeAPO-34F, Me = Mn(II), Co(II), Ni(II)] have been calculated ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Synthesis and characterization of thermoplastic poly(ester-siloxane)s
(Wiley-Blackwell, 2001)
Two series of thermoplastic poly (ester-siloxane)s, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) as the hard segment, were synthesized by two-step catalyzed transesterification ...
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 ...
Synthesis and characterization of biodegradable poly(butylene succinate-co-butylene adipate)s
(Elsevier Sci Ltd, Oxford, 2001)
A series of high molecular weight polyesters, poly(butylene succinate-co-butylene adipate)s was prepared from dimethyl succinate, dimethyl adipate and 1,4-butanediol by catalyzed transesterification in the melt. The ...
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 ...
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 ...
Characteristics of natural isolates of lactic acid bacteria selected for construction of starter cultures for semi-hard cheese of the Trapist type
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2001)
Starter cultures (S12, S19 and S21) for semi-hard cheese of the Trapist type were constructed by using natural isolates of lactic acid bacteria (LAB) that were mostly isolated from home-made cheese. These starter cultures ...
