Abstract: A method for cooking a food including free water, uses a cooking vessel having at least one cooking surface, the cooking surface being such that a drop of distilled water can form a contact angle with the cooking surface that is greater than or equal to 150° at ambient temperature, and the food being such that its water activity aw is greater than or equal to 0.5. The method includes heating the cooking surface to a minimum temperature of 125° C.; placing the food on the cooking surface; and cooking the food on the cooking surface.

Abstract: The invention relates to a heat exchanger comprising parallel plates and spacers arranged in parallel and defining i) rough primary channels and ii) secondary channels arranged so as to exchange heat. Said heat exchanger comprises a primary liquid inlet to be fluidically connected to a primary liquid dispenser. Each rough primary channel has the shape of a prism having a polygonal cross-section and consisting of a plurality of essentially flat faces. The primary channels comprise rough primary channels. Each rough primary channel has microstructure elements which are distributed along the entire length of the channel and have dimensions of between 1 ?m and 300 ?m.

Abstract: The invention relates to an article having a nanotextured surface with superhydrophobic properties, comprising an array of vertical tabs, preferably regular, wherein the pillar array fulfils the following conditions: the surface fraction of the pillars Øs is such that 3%?Øs?13%, preferably 5%?Øs?12%, preferably 5%?Øs?13%, even better 5.5%?Øs?13%, even better 6%?Øs?13%, and better still 8%?Øs?13%; the pitch p of the array is such that 100 nm?p?250 nm; the height h of the pillars is such that 100 nm?h?400 nm, preferably 250?h?400 nm, even better 300?h?400 nm; and the lateral surface of the pillars is inclined at most by an angle of ±20°, preferably ±10° or even better ±5°, in relation to the vertical axis of the pillars.

Abstract: The present invention relates to a process for producing surfaces on which, at a temperature T≧T1, liquids A do not adhere or adhere only poorly, and in particular for producing surfaces with low susceptibility to soiling. The invention also relates to articles which have at least one such surface.
