Thermophysical Properties at Ultrafast Timescales

Using ultrafast calorimetry, we have been able to determine thermophysical properties at several 10⁵ K/s heating and cooling rates. In this way, we (i) discovered new phase transition pathways where (meta-)stable solids transform into each other via intermediate melting; (ii) identified new glass states with particular glass formation and phase stability; and (iii) invented a new experimental strategy for discovering metastable crystals.

Our current research focuses on the development of correlative in situ methodologies to measure simultaneously the thermal and structural properties of a material, and determine its related phase transformations.
