Heterogeneous surface with polar functional groups as nucleation points. These nucleation points cause precipitation of a substance, for example ice or salt, in a fluid at these nucleation points under suitable physical conditions because the Gibbs free energy of the system is lower at the nucleation points than between the nucleation points, where said system comprises said surface and said fluid with said substance near said surface.
L'invention concerne une surface hétérogène pourvue de groupes fonctionnels polaires servant de points de nucléation. Ces points de nucléation entraînent, dans des conditions physiques adéquates, la précipitation d'une substance (par ex : de la glace ou un sel) contenue dans un fluide situé au niveau desdits points de nucléation, car l'énergie libre de Gibbs du système est inférieure au niveau de ces points de nucléation qu'elle ne l'est entre eux. Ledit système comprend ladite surface, et à proximité de celle-ci, ledit fluide contenant ladite substance.
