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. Entfacht habe ihn wohl der Physiker Heiner Linke, der 2006 zur Bewegung der Leidenfrostschen Tropfen veröffentlichte.

In the context of electronics, this is the principle of thermoelectric energy conversion. For a long time it was thought that Brownian heat engines (and thermoelectric devices) are inherently irreversible and would therefore necessarily fall Site with high-speed video, pictures and explanation of film-boiling by Heiner Linke at the University of Oregon, USA "Scientists make water run uphill" by BBC News about using the Leidenfrost effect for cooling of computer chips . Dr Heiner Linke: We could hardly believe that it could be so simple and that nobody had seen this before.

The surprising effect is that there is an ideal temperature range in which the drop of water will skip and dance for the longest time. When the frying pan is just above the boiling temperature of water, which is 100C at sea level, the drop of water should boil away fairly quickly. These Leidenfrost drops are ultra-mobile, and we show how they can be manipulated, or trapped.

These Leidenfrost drops are ultra-mobile, and we show how they can be manipulated, or trapped. We also describe a device recently invented by Heiner Linke, allowing them to self-propel along their substrate. More generally, it is found that these frictionless systems are good tools for studying the mechanics of interfaces. Info. Programme

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.
