Special Issue "Thermal Analysis Kinetics for Understanding Materials Behavior"
Deadline for manuscript submissions: 30 June 2019

Changing the temperature of a substance can stimulate dramatic changes of its state. These changes can be intermolecular (physical) and intramolecular (chemical) in nature. Physical changes occur without breaking intramolecular bonds, and lead to transitions between the four major phases: gas, liquid, crystal, and glass. Chemical changes are associated with chemical reactions that originate from breaking intramolecular bonds. Phase transitions as well as chemical reactions occur at finite rates. Measuring the rates of processes is the realm of kinetics. The kinetics of thermally stimulated processes is measured routinely by thermal analysis techniques such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
Knowing the process rates and their dependence on temperature is of vital importance for understanding the behavior of materials exposed to variations in temperature. For example, the successful function of glassy materials is contingent upon negligibly small rates of the transition from the glass to crystalline phase. On the other hand, phase change materials rely on rapid transition between the liquid and crystalline phases. Similar principles hold for chemical reactions. Slower rates of chemical decomposition give rise to longer drug shelf lives. However, very fast decomposition rates determine the efficiency of explosives and propellants.
In recent years, thermal analysis kinetics has made significant progress by developing computational tools for reliable kinetic analysis. It has also expanded its traditional application area to newly developed nano- and bio-materials. The purpose of this Special Issue is to collect a series of papers that reflect recent developments in the field and highlight the essential role of thermal analysis kinetics in understanding the processes responsible for the thermal behavior of various materials. The processes of interest involve (but are not limited to): thermal decomposition (degradation), polymerization, crosslinking (curing), oxidation, reduction, crystallization, melting, and glass and solid–solid transitions.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
