Rationale and fallacy of thermoanalytical kinetic patterns

How we model subject matter


Modeling tradition is reviewed within its historical maturity from Plato do Penrose. Metaphors in nonisothermal kinetics achieved a wide application mostly employing models derived by means of undemanding isothermal descriptions. Geometrical basis of such modeling is revised and discussed in terms of symmetrical and asymmetrical (pentagonal) schemes. The properties of interface (reaction separating line) are found decisive in all cases of heterogeneous kinetics. Application of fractal geometry is accredited, and associated formal kinetic models based on nonintegral power exponents are acknowledged. Typical erroneous beliefs are dealt with showing common kinetic misinterpretation of measured data and associated mathematical manipulability of kinetic equations. The correction of a measured DTA peak is mentioned assuming the effects of heat inertia and temperature gradients.

The results were developed within the CENTEM project, reg. no. CZ.1.05/2.1.00/03.0088 that is co-funded from the ERDF within the OP RDI program of the Ministry of Education, Youth and Sports. I feel also indebted to my scientific friends, coworkers, and uppermost kineticists: late Joseph H. Flynn (Bethesda), Jerry Czarnecki (Fullerton), Klaus Heide (Jena), Pavel Holba (Prague), Nobuyoshi Koga (Hiroshima), Jiří Málek (Pardubice), Eugéne Segal (Bucharest), Peter Šimon (Bratislava), Donald R. Uhlmann (Tucson) and Živan Živkovič (Serbian Bor).
