摘要： A process for producing pigments having a defined size and shape and also pigments produced by this process. The process has the steps: a) production of a three-dimensional surface structure on a substrate, with surface regions which are in each case partly bounded by a plurality of three-dimensional structural elements and are arranged in gaps being formed; b) application of a pigment material layer to the surface structure; c) detachment of the pigment material layer from the surface structure and production of pigments.

摘要： The present invention relates to a preparation method of a copper green rust pigment, particularly a preparation method of a copper green rust pigment that can replace the traditional Dancheong Hayeob pigment comprising the following steps: a step of preparing a copper powder comprising at least one of copper; and a copper alloy comprising copper and at least one of tin (Sn), zinc (Zn), and lead (Pb); and a step of corroding the copper powder by mixing the copper powder with a corrosive agent containing sodium chloride and ammonium chloride. The corrosive agent includes 75 to 90 weight % of the sodium chloride and 10 to 25 weight % of the ammonium chloride based on the total weight.

摘要： Thermoelectric (TE) nanocomposite material that includes at least one component consisting of nanocrystals. A TE nanocomposite material in accordance with the present invention can include, but is not limited to, multiple nanocrystalline structures, nanocrystal networks or partial networks, or multi-component materials, with some components forming connected interpenetrating networks including nanocrystalline networks. The TE nanocomposite material can be in the form of a bulk solid having semiconductor nanocrystallites that form an electrically conductive network within the material. In other embodiments, the TE nanocomposite material can be a nanocomposite thermoelectric material having one network of p-type or n-type semiconductor domains and a low thermal conductivity semiconductor or dielectric network or domains separating the p-type or n-type domains that provides efficient phonon scattering to reduce thermal conductivity while maintaining the electrical properties of the p-type or n-type semiconductor.
