TL;DR: In this article, the Pitzer ion-interaction model was used to derive the volumetric and heat capacities of aqueous solutions of HCL at molalities from 0.1 to 6.0 mol·kg−1, temperatures from 298.15 K to 623 K, and pressures of 10 MPa and 28 MPa with a vibrating tube flow densimeter.

TL;DR: In this article, an adiabatic calorimeter was used to measure the enthalpy of fusion of a very pure sample of indium, which was determined to be ΔfusH = (28.6624 ± 0.0076) J·g-1, where the uncertainty corresponded to a 95% confidence interval.
Abstract: An adiabatic calorimeter was used to measure the enthalpy of fusion of a very pure sample of indium. The new value of the enthalpy of fusion was determined to be ΔfusH = (28.6624 ± 0.0076) J·g-1, where the uncertainty corresponded to a 95% confidence interval. The temperature of fusion of this sample was found to not differ from the ITS-90 assigned value within the accuracies of the thermometry used in the present study. A comparison with previous determinations is made.

TL;DR: The ability of the Photopyroelctric calorimetry to study the versus temperature behaviour of the specific heat and of the other thermal parameters in the vicinity of phase transitions is outlined.
Abstract: The study of thermophysical properties is of great importance in several scientific fields. Among them, the heat capacity, for example, is related to the microscopic structure of condensed matter and plays an important role in monitoring the changes in the energy content of a system. Calorimetric techniques are thus of fundamental importance for characterizing physical systems, particularly in the vicinity of phase transitions where energy fluctuations can play an important role. In this work, the ability of the Photopyroelctric calorimetry to study the versus temperature behaviour of the specific heat and of the other thermal parameters in the vicinity of phase transitions is outlined. The working principle, the theoretical basis, the experimental configurations, and the advantages of this technique, with respect to the more conventional ones, have been described and discussed in detail. The integrations in the calorimetric setup giving the possibility to perform, simultaneously with the calorimetric studies, complementary kind of characterizations of optical, structural, and electrical properties are also described. A review of the results obtained with this technique, in all its possible configurations, for the high temperature resolution studies of the thermal parameters over several kinds of phase transitions occurring in different systems is presented and discussed.
