    摘要: Optical components have a material-distribution gradient due to nanometer-size particles embedded in a solid matrix. The components are manufactured by forming a dispersion of nanometer-size particles in a liquid, curable matrix material, causing the particles to migrate in the matrix material on the basis of a potential difference to form a distribution gradient, and subsequently curing the matrix material, retaining the distribution gradient. The method is suitable for use in the manufacture of optical lenses with a refractive index gradient.

    摘要: The aim of the invention is to provide particles or coatings for splitting water, which are largely protected from corrosive damage. To this end, the particles or the coating consist(s) of a nucleus or a sub-layer and a shell or top layer, the nucleus or the sub-layer forming a reactive unit and consisting of a material which, on input of energy from sunlight, releases electrons capable of splitting water into hydrogen and oxygen, and the shell or top layer forming a protective unit capable of keeping the cleavage products away from the surface of the reactive unit and simultaneously having conductive fractions. Surprisingly, it has been found that corrosive damage to the reactive particles is (largely) prevented by the targeted separation of the reaction particles and the cleavage products over the kinetic range of the released electrons.

    摘要: Suspensions and powders based on indium tin oxide are prepared by a method in which indium tin oxide precursors are precipitated from solutions in one or more solvents in the presence of one or more surface-modifying components, the solvent(s) are removed from the precipitate, which is then calcined, one or more surface-modifying components and one or more solvents are added, the mixture is comminuted or dispersed to form a suspension, and the liquid components are separated from the suspension to give a powder. The powder may be converted into a moulding by a shaping process. The materials prepared by this method are especially suitable as coating materials for use in microelectronics and optoelectronics.
