Induction time and later degradation of outdoor exposed polypropylene cast film studied by differential scanning calorimetry

In the simultaneous measurement of heat capacity by differential scanning calorimetry and ac calorimetry using the same apparatus with ac temperature modulation superposed on a linear temperature ramp, the principle of measurement by ac calorimetry is not sufficiently understood yet. This paper gives an explanation, especially from the viewpoint of ac calorimetry. The experimental conditions required for the simultaneous measurement are considered.

Excess heat capacity of the (Li1−Ca )F1+ liquid solution determined by differential scanning calorimetry and drop calorimetry

The Journal of Chemical Thermodynamics (2014)

E. Capelli O. Beneš R.J.M. Konings

The work presents the measured heat capacity of the (Li1−xCax)F1+x liquid solution. Four samples with different compositions have been prepared and measured using a Differential Scanning Calorimeter. Since this technique was newly adopted for measuring encapsulated fluoride samples, some modifications were introduced in the standard configuration of the instrument and they are described in this work as well. For comparison one of the analysed composition (xCaF2 = 0.5) was also measured using drop calorimetry, which has been previously used for similar studies. The reliability of the results obtained was confirmed by the good agreement between the two techniques. Moreover, the excess heat capacity of the (Li1−xCax)F1+x liquid solution was derived and a strong deviation from the ideal behaviour was observed.
