The thermal degradation kinetics of poly(chlorethylmethacrylates)
(John Wiley & Sons Ltd, W Sussex, 1992)
The thermal degradation kinetics of poly(2-mono-, 2,2-di- and 2,2,2-trichlorethyl methacrylate) and of the non-chlorinated poly(ethyl methacrylate) were studied by TG in the absence and presence of oxygen. The overall ...
The thermal degradation kinetics of dextran and pullulan
(John Wiley & Sons Ltd, W Sussex, 1993)
The effect of molar mass and, in the case of dextran, of the degree of branching on the thermal degradation kinetics of dextran and pullulan was studied in the presence and absence of oxygen. Although the initial mass loss ...
The non-oxidative thermal degradation of poly (Di-2-chloroethyl itaconate)
(John Wiley & Sons Ltd, W Sussex, 1993)
The non-oxidative thermal degradation of poly (di-2-chloroethyl itaconate) (PD2CEI) was studied by TG and by analysing the thermal products. The major processes occurring during thermal analysis are crosslinking, ...
Factors influencing the removal of divalent cations by hydroxyapatite
(Elsevier, Amsterdam, 2008)
The effect of pH, contact time, initial metal concentration and presence of common competing cations, on hydroxyapatite (HAP) sorption properties towards Ph2+, Cd2+, Zn2+, and Sr2+ ions was studied and compared using a ...
Nonlinear FR-ZLC method for investigation of adsorption equilibrium and kinetics
(Springer, New York, 2008)
A new method for investigation of adsorption equilibrium and kinetics, named Nonlinear Frequency Response-Zero Length Column (NFR-ZLC) method, is introduced. It combines the advantages of the Nonlinear FR method (the ...
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 ...

(141st Annual Meeting and Exhibition, TMS 2012, 2012)
This work presents the laboratory testing results of kinetics the oxidation process and sample processing of the sulphide polymetallic concentrate Blagojev Kamen. The aim of investigation is recovery of these types of raw ...
The kinetics of the thermal degradation of isomeric dipropyl and dibutyl esters of poly(itaconic acid)
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
Non-oxidative and oxidative thermogravimetry was performed on poly(di-n-propyl-) (PDnPI), poly(di-iso-propyl-) (PDiPI), poly(di-n-butyl-) (PDnBI), poly(di-iso-butyl-) (PDiBI) and poly(di-sec-butyl itaconate) (PDsBI). The ...
Non-isothermal crystallization of k2o center dot tio2 center dot 3geo(2) glass
(Springer, Dordrecht, 2009)
The crystallization of K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal condition was studied. In powdered glass with particle sizes less than 0.15 mm, surface crystallization was dominant and an activation ...
Applications of non-linear frequency response for investigation of adsorption systems
(Soc Chemists Technologists Madeconia, Skopje, 2009)
Two main directions of application of nonlinear frequency response and the concept of higher order frequency response functions (FRFs) in investigation of adsorption systems are presented, one for development of novel ...
