The 11th Conference on Calorimetry and Thermal Analysis (CCTA 11) is another in a series of meetings of the Polish Society of Calorimetry and Thermal Analysis PTKAT, traditionally held in Zakopane (Poland). The main aim of the Conference is promoting the scientific discussions and exchange of ideas between researchers involved in calorimetry and thermal analysis. These techniques are used in various fields of scientific research. The main topics of the Conference are the applications of calorimetry and thermal analysis to studying inorganic, organic and biological materials, kinetics and reactivity of solids, solution calorimetry, food systems etc. Very important issue is the progress and new solutions in theory and instrumentations and technical applications.
