Thermo (ISSN 2673-7264) provides an advanced forum for studies related to topics in all areas dealing with experimental, theoretical, and applied thermal sciences. It publishes original research papers, letters, reviews, as well as Special Issues on particular subjects. The main topics covered in the journal include all aspects of heat and temperature, encompassing the joint study of thermodynamics, statistical mechanics, and kinetic theory. Other satellite topics dealing with thermophysics, solubility phenomena, chemical thermodynamics, and chemical engineering are also very welcome. The aim of Thermo is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, the journal has no restriction on the maximum length of the papers. Full experimental details should be provided so that the results can be reproduced. Furthermore, papers dealing with good research practice: i) introducing theoretical or experimental methods or ii) dealing with equipment calibrations and measurement recommendations, are also accepted to provide solid textbooks for undergraduate and postgraduate students.
