Abstract: A method for generating oxidic nanoparticles from a material forming oxide particles, comprising the steps of: preparation of an aqueous solution containing ions of the material forming the oxide particles, film evaporation of the solution at a temperature above 200° C., and skimming off the nanoparticles floating on the surface of the aqueous solution generated in the vicinity of the vapor film on film evaporation. A device for performing the method is also provided.

Abstract: Disclosed is a method for producing regularly arranged nanowires from a nanowire-forming material on a substrate. Said method is characterized by the following steps: a) the material is introduced into a carrier liquid at a load remaining at least three orders of magnitude below the loading capacity of the carrier liquid; b) a guiding member is placed on the substrate; c) the substrate is heated to a temperature at which a thin film of the carrier liquid undergoes spinodal decrosslinking on the substrate; d) a film of the carrier liquid that is loaded with material is applied to the heated substrate in the surroundings of the guiding member, where a gradient of the average film thickness is obtained perpendicular to the contour of the guiding member; and e) the carrier liquid is evaporated such that the material is left along lines extending perpendicular to the gradient of the film thickness.

Abstract: A method for producing nanostructures on a substrate, by dripping a solution of nanostructure-forming material in water onto the substrate heated to a temperature above the temperature at which a drop of the solution is initially suspended on a vapor cushion after being applied by dripping onto the substrate, with nanostructures being formed when the drops evaporate.

Abstract: A method for producing a plurality of regularly arranged nanoconnections on a substrate using an elastic masking layer forming cracks. Said method comprises the following steps: the masking layer is microstructured in order to produce at least one defined region provided with a masking over which the nanoconnections are to extend; cracks are produced in the masking layer; the material forming the nanoconnections is applied at least to the structures of the masking layer in the cracks and to the non-masked regions of the substrate; the masking layer with the is removed, and the defined region is covered with an essentially rectangular masking strip, over the width of which the nanoconnections are to extend the length of the strip being longer than the width; and a self-organized regular crack pattern comprising a plurality of crack lines is produced by inducing stress in the masking strip, such that a plurality of regularly arranged nanoconnections is formed over the at least one defined region.
