TY - JOUR TI - On the p(x) approximation in the non-isothermal reaction kinetics by a generalized exponential integral the concept AU - Hristov Jordan Y AU - Karadjova Veronika JN - Thermal Science PY - 2021 VL - 25 IS - 102 SP - 321 EP - 326 PT - Article AB - A non-Arrhenius model based on the Mittag-Leffler function has been conceived as a basic concept. This approach allows modelling both sub-Arrhenius and super-Arrhenius behaviours and giving rise to modified temperature integrals.
