Abstract:
... An alternative approach for microwave calorimetry is proposed which relies on the synchrotron radiation powder diffraction technique as well as on the Grüneisen formalism for the analysis of thermal expansion. Cobalt was selected as suitable magnetic material for the present evaluation of the method. First results are reported concerning the calorimetric assessment of the HCP (hexagonal close-pack ...

Abstract:
... Differential scanning calorimetry (DSC) and numerical simulations have been used to determine some kinetics parameters of phase change materials (PCM). The heating rate affects the development of the DSC thermograms and also the apparent specific heat capacity of the PCM during the phase change process. PCM geometry has also a definitive influence on the DSC thermograms and on the apparent specifi ...

Abstract:
... Heat pulse methods include the dual-probe (DP) and single-probe (SP) methods. The DP method is a widely used method for determining the thermal conductivity (K) and thermal diffusivity (β) of soil. The SP method has been traditionally used for measuring K only. The objective of this study was to examine if the SP method can be used to estimate the thermal properties of air-dried soils. The thermal ...

Abstract:
... Thermodynamic properties of bread dough (fusion enthalpy, apparent specific heat, initial freezing point and unfreezable water) were measured at temperatures from −40 °C to 35 °C using differential scanning calorimetry. The initial freezing point was also calculated based on the water activity of dough. The apparent specific heat varied as a function of temperature: specific heat in the free ...
