Thermosalient (’jumping’) crystals — •Ivor Lončarić1, Jasminka Popović1, Vito Despoja2, and Željko Skoko2 — 1Ruđer Bošković Institute, Bijenička 54, HR-10000 Zagreb, Croatia — 2Department of Physics, Faculty of Science, University of Zagreb, Bijenička 32, HR-10000 Zagreb, Croatia
Thermosalient materials when heated or cooled are characterized by a fast and energetic phase transition in which crystals experience macroscopic change in dimensions and jump to distances much larger than their own dimension. Since the first systematic study , there has been a rising intrest for these interesting, and potentially useful, acutating materials. As a one example, N-2-propylidene-4-hydroxybenzohydrazide shows irreversible thermosalient phase transition from Form I to Form II and reversible thermosalient phase transition from Form II to Form III. We combine experiments and first-principles electronic structure calculations to elucidate this interesting and technologically useful phenomenon.
