Brief overview of two centuries of imaginative calorimetry
X CONGRESSO BRASILEIRO E IV CONGRESSO PAN AMERICANO DE ANÁLISE TÉRMICA E CALORIMETRIA 17 – 20 de abril de 2016 – São Paulo – SP – Brasil Dr. Jean Rouquerol Title Brief overview of two centuries of imaginative calorimetry Summary Carrying out good calorimetric studies has never been an easy task. This is because of the difficulties (i) to « catch » the heat, which escapes so easily and (ii) to get well-characterized starting and final states of the system. Teaching calorimetry is also uneasy, due to the more than 100 calorimeters which were devised, either to improve the accuracy or sensitivity of the measurement or to suit specific applications. For the sake of an easy understanding (and hopefully of a fruitful teaching) we shall therefore propose a unified presentation of calorimetry. We shall first address the issue of the definition of heat (i.e. the physical quantity measured by a calorimeter), since, quite surprisingly, no general agreement does exist about it between various groups of scientists: for some calorimetrists and thermal engineers, heat can be stored (whereas for many thermodynamicists and physical chemists it cannot) and for a number of physicists heat cannot be transferred by radiation (which is not the opinion of a majority of scientists from other fields). We shall look for a definition able to be accepted by most of us. In a second part, we shall address the issue of the complexity and variety of calorimeters, which gave rise to more than 10 different nomenclatures: each one having its own, specific, objective or starting from a central calorimeter (either the most commonly used at the time of the presentation or the one devised and developed by the author of the nomenclature…). With the objective of making easier the teaching of calorimetry, we shall see how a few clear-cut criteria provide a nomenclature easy to handle, encompassing all existing calorimeters. This will give us the opportunity to stress the major original features of a number of calorimeters and to see to which extent they can meet our present needs.

Application to the preparation of technological adsorbents with tailor-made porosity and highly reproducible surface properties. This approach was generalized under the generic, well-accepted name of Sample-Controlled Thermal Analysis (SCTA) and is available in many instruments. b) Gas adsorption and liquid adsorption, with special attention to its thermodynamic study. He developed unique adsorption microcalorimetry set-ups able to operate either at 77 or 87 K (for a critical assessment of the specific surface area, by either gas or liquid adsorption) or up to 50 bar, for the sake of gas separation and storage.
