Experimental progress in adiabatic, cryogenic calorimetry is tersely reviewed and contrasted with other techniques for heat capacity determinations in this temperature region—including DSC. Trends and prognostications of important developmente including scaling down sample size and use of adjuvant thermometry.

Cryogenic heat-capacity determinations provide a useful tool for the determination of the energetic spectrum of condensed phases and also reveal information on their discrete electronic level structures as well. We have been interested in applying these techniques to actinide elements and have in recent months been working up the techniques to unravel the corresponding data for the lanthanide compounds—where opposite trends in cationic masses and molar volumes provide an opportunity to test theories useful for the resolution of excess heat capacity from lattice contributions.
