Abstract:
A process for producing a crystalline substrate with an optical multi-layer system thereon and the crystalline substrate obtainable thereby. The process comprises the successive application of at least two free-flowing compositions which comprise nanoscale inorganic solid particles comprising at least one of a polymerizable and a polycondensable organic group to a surface of the crystalline substrate and the polymerization and/or polycondensation of the organic groups of the solid particles to form organically crosslinked layers on the substrate and a single-stage thermal consolidation of these layers with a burnout of organic constituents thereof. The at least two compositions give rise to layers with different refractive indices.
Abstract:
A consolidation agent for moulded articles and geological formations from porous or particulate materials, containing a hydrolysate or precondensate of (a) at least one organosilane of the general formula (I) RnSiX4-n (I) in which the radicals R are identical or different and are not hydrolytically removable groups, the radicals X are identical or different and are hydrolytically removable groups or hydroxyl groups, and n is 1, 2 or 3, and optionally (b) at least one hydrolyzable silane of the general formula (II) SiX4 (II) in which the radicals X have the meaning defined above.

Abstract:
This invention relates to a connector (1) for connecting a dialysate port (31) of a hemodialysis machine with a dialysate-carrying line. The inventive connector (1) has a recess (6, 6′) with a shift element (3) on the end (4) which accommodates the dialysis machine port (31), whereby the shift element (3) is accommodated in the recess and is displaceable between a first position and a second position perpendicular to the direction of the lumen (8) on this end (4). The shift element (3) does not pass through the lumen (8) in the first position. In the first position, the lumen (8) is constricted so that the connector (1) with the shift element (3) can be placed on the dialysate port (31), and in the second position it can be locked on the dialysate port (31) by means of an undercut (30) thereon. The inventive connector is suitable for production as a disposable item in comparison with the widely used Hansen coupling. At the same time, a simple and reliable connection of a dialysate-carrying line to a dialysate port of a hemodialysis machine is possible, and does not require any structural measures on the dialysis machine itself.

Abstract:
The present invention provides compositions containing transparent thermoplastic polymer, surface-modified oxide particles with a particle size of less than 200 nm, and organic NIR absorbers. The compositions of the present invention may find use in reducing diathermancy in sheets, films, glazing systems and roofing systems which may be incorporated into automobiles and buildings.
Abstract:
This invention relates to a catalytic composition which comprises a coating of a coating material on a support and is obtainable by applying the coating material, comprising (1) a polycondensate of at least one hydrolysable organosilane and also, if desired, one or more compounds of glass-forming elements, and (2) particles of one or more transition metal oxides, the weight ratio of transition metal oxide particles to polycondensate being from 10:1 to 1:10, to the support and subjecting the applied coating material to thermal treatment. The invention also relates to a process for preparing this catalytic composition and to its use for the purpose of deodorizing or oxidizing organic components or carbon.
Abstract:
The present invention relates to the use of amines and/or Mannich adducts as detergents and/or dispersants in fuel and lubricant compositions for direct-injection gasoline engines. The invention further relates to fuel and lubricant compositions which comprise at least one such Mannich adduct, and also a bisaminoalkylated Mannich adduct.
Abstract:
A process for producing a dispersion of at least two types of finely divided particles. The process comprises providing at least a first type and a second type of finely divided particles with opposite surface charges and particle sizes which differ by a factor of at least three, and combining the particles and a dispersion medium and forming a substantially homogeneous dispersion of the at least two types of finely divided particles.
Abstract:
Magnetic particles with an outer glass surface being essentially poreless or having pores of a diameter of less then 10 nm as well as ferromagnetic particles with a glass surface are preferentially useful for the isolation of biological material from samples. They provide a quick and reliable purification.
Abstract:
Substrates comprising a photocatalytic layer containing TiO2 are produced using TiO2 particles which may optionally be doped with metallic or non-metallic elements or compounds. The photocatalytic layer exhibits a concentration gradient of the TiO2 particles. An organically modified inorganic hybrid layer may be provided between the substrate and the photocatalytic layer.
Abstract:
A polymer film with an optical interference system. The optical interference system comprises at least two layers of different refractive index, which layers comprise nanoscale inorganic particles having organic surface groups that are polymerizable and/or polycondensable. The layers are at least partially crosslinked through the organic surface groups.
