Abstract: When a container filled with granular material is subjected to vertical vibration in the presence of gravity, under certain conditions a non-monotonous density profile can be observed. This effect which is characteristic for dissipative granular… read more here.

DOI: 10.1021/jacs.2c10763
Abstract: The Leidenfrost effect describes a fascinating phenomenon in which a liquid droplet, when deposited onto a very hot substrate, will levitate on its own vapor layer and undergo frictionless movements. Driven by the significant implications… read more here.

Abstract: Water droplets skid across hot surfaces, hovering imperceptibly as they undergo rapid vaporization. Elastic solids are now shown to exhibit a variant of this behaviour, engaging in sustained bouncing by coupling vapour release to elastic… read more here.

Abstract: By sufficiently heating a solid, a sessile drop can be prevented from contacting the surface by floating on its own vapour. While certain aspects of the dynamics of this so-called Leidenfrost effect are understood, it… read more here.

DOI: 10.1103/physrevlett.127.124502
Abstract: Volatile drops deposited on a hot solid can levitate on a cushion of their own vapor, without contacting the surface. We propose to understand the onset of this so-called Leidenfrost effect through an analogy to… read more here.
