Correlation between chemical composition of the γ-Bi2O3 phase and the properties of ZnO varistors
(Chemical Industry and Chemical Engineering Quarterly, 2005)
Four varistor samples differing in chemical and phase composition of the starting Bi2O3 phase were prepared by the method of direct mixing of the constituent phases (DMCP), i.e. by sintering the mixture of the previously ...
A kinetic study of D-glucose oxidation by bromine in aqueous solutions
(Elsevier Sci Ltd, Oxford, 2006)
The kinetics of the oxidation Of D-glucose to D-gluconic acid by bromine in aqueous solution were studied using potentiometric techniques and theoretical considerations of complex bromine-bromide-pH equilibria. The pH has ...
Synthesis of thermoplastic poly(ester-siloxane)s in the melt and in solution / Sinteza termoplastičnih poli(estar-siloksana) u rastopu i rastvoru
(Serbian Chemical Society, 2005)
Two series of thermoplastic elastomers, based on poly(dimethylsiloxane) PDMS, as the soft segment and poly(butylene terephthalate), PBT, as the hard segment, were synthesized by catalyzed transesterification, from dimethyl ...
Oxidative modifications of cellulose in the periodate system - Reduction and beta-elimination reactions
(Walter de Gruyter & Co, Berlin, 2009)
The conversion of cellulose to dialdehyde cellulose (DAC) by treatment with aqueous periodate was studied by the CCOA method, which is a combination of gel permeation chromatography and carbonyl-selective fluorescence ...
The effect of electrodeposition process parameters on the current density distribution in an electrochemical cell
(Serbian Chemical Society, 2001)
Cell voltage - current density dependences for a model electrochemical cell of fixed geometry were calculated for different electrolyte conductivities, Tafel slopes and cathodic exchange current densities. The ratio between ...
Preparation of a-TCP cements from calcium deficient hydroxyapatite obtained by hydrothermal method
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
