Efek Leidenfrost adalah fenomena fisika di mana cairan, yang berdekatan dengan massa yang secara signifikan lebih panas daripada titik didih cairan, menghasilkan lapisan uap yang mengisolasi cairan dari mendidih dengan cepat. Karena 'kekuatan repulsif' ini, tetesan melayang di atas permukaan daripada membuat kontak fisik dengannya. Fenomena ini paling sering terlihat saat memasak: ketika The Leidenfrost point was found to be 100-105 degC above the saturation temperature for all liquids except water; for water, the exact value of the Leidenfrost point appears to depend upon the Linke and his Australian colleague Paul Curmi began discussing the idea in Sydney, where Linke did his postdoc between 1998–2001. “This is an old dream that we started working seriously on just over ten years ago, but we had a hard time finding joint funding for. It will be great fun to pick this back up”, says Heiner Linke.

A common theme is the physics of ratchets and Brownian motors: the question how thermal fluctuations in non-equilibrium systems can be harvested to produce useful work, for example in thermoelectricity or in molecular Heiner Linke, född den 21 september 1966, är en tysk-svensk fysiker samt professor i nanofysik vid Lunds universitet.. 1997 disputerade Linke på sin doktorsavhandling Quantum Electronic Transport in Low-Dimensional Semiconductors i fasta tillståndets fysik vid Lunds Universitet. Properties such as asymmetry and disequilibrium can be exploited in order to obtain useful work from a physical system. Our group is investigating one particularly interesting manifestation of the ``ratchet'' effect. We find that film-boiling (leidenfrost) drops of liquid placed on an asymmetrically-structured surface experience acceleration significant enough for transport to occur even Heiner Linke, Birte Höcker, Ken’ya Furuta, Nancy R.

Entfacht habe ihn wohl der Physiker Heiner Linke, der 2006 zur Bewegung der Leidenfrostschen Tropfen veröffentlichte. Linke hatte darin beschrieben, wie sich der Tropfen auf einer geriffelten Oberfläche durch eine Veränderung der Temperatur in unterschiedliche Richtungen – auch bergauf – bewegen lässt.

The second is our experimental effort to demonstrate a near-Carnot efficient thermal-to-electric energy converter [3] The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than its boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly.
