Sergey Vyazovkin,Konstantinos Chrissafis,Maria Laura Di Lorenzo,Nobuyoshi Koga,Michèle Pijolat,Bertrand Roduit,Nicolas Sbirrazzuoli,Joan Josep Suñol +7 more
TL;DR: In this paper, the authors present a set of recommendations for obtaining kinetic data that are adequate to the actual kinetics of various processes, including thermal decomposition of inorganic solids; thermal and thermo-oxidative degradation of polymers and organics; reactions of solids with gases; polymerization and crosslinking; crystallization of polymer and inorganics; hazardous processes.

Kinetic Analysis of Solid-State Reactions: The Universality of Master Plots for Analyzing Isothermal and Nonisothermal Experiments
TL;DR: In this paper, the concept of generalized time, introduced by Ozawa, has been used to define master plots for the analysis of solid-state reactions, regardless of the type of temperature program used for recording the experimental data.
Journal ArticleDOI

TL;DR: A 10-year cooperative effort between the U.S. National Institute of Standards and Technology (NIST) and five major journals in the field of thermophysical and thermochemical properties to improve the quality of published reports of experimental data is described in this article.
Journal ArticleDOI
Crystallization of amorphous calcium carbonate
TL;DR: In this paper, the enthalpy change and activation energy of the crystallization process increased with increasing pH value of sample preparation, ranging from 3.99 to 12.26kJ(mol CaCO 3 ) −1 and from 151.6 to 304.1kJ (kJ)mol −1, respectively.
