  • Patent number: 8313797
    Abstract: Provided is a method for in-situ coating a substrate or matrix with magnetic metal nanoparticles. A metal salt, which may be organic or inorganic, is introduced into a solution of liquid polyol. In the presence of mechanical stirring and heat, a reduction process occurs wherein the magnetic metal nanoparticles precipitate out of solution and deposit or attach to one or more surfaces of the substrate. The concentration of reaction precursors, combined with the polyol, may be varied to control the size and shape of the magnetic nanoparticles.

  • Publication number: 20110287181
    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.
