Phase-transition-induced jumping, bending, and wriggling of single crystal nanofibers of coronene

Abstract For decades, it has been reported that some organic crystals suddenly crack, break, or jump when they are heated from room temperature. Recently, such crystals have been intensively studied both in fundamental science and for high-speed mechanical device applications. According to these stu...
