Abstract: A liquid or pasty pigment and/or filler preparation comprising: 1 to 70% by weight of at least one pigment dispersed in the preparation and/or at least one filler dispersed in the preparation (component (A)), 1 to 25% by weight of at least one inorganic, particulate component dispersed in the preparation, as component (B), 0 to 10% by weight of at least one surface-active wetting agent, which preferably also has dispersing properties, and as the remainder water and/or at least one solvent, the particles of component (B) being nanoscale or microscale and being inorganically or organically surface-modified, the surface modifier used being selected such that component (B) has a cationic, anionic, amphoteric or non-ionic surface, and component (B) further has a zeta potential which is opposite to the charge of the particles of component (A) or, in the case of uncharged particles of component (A), has a zeta potential in the range of ?60 to +40 mV so as to effect adhesion of the particles (B) to the pigment and/or

Abstract: The invention relates to a method for preparing emulsions. In order to create a new method for preparing emulsions, in which homogenous oil droplets as small as possible can be generated with an energy input as low as possible, it is proposed in the scope of the invention, that at least two liquid streams of liquids that cannot be intermixed with one another are pumped through separate openings with defined diameters, in order to achieve flow velocity of the liquid streams of more than 10 m/sec., and in that the liquid streams collide at a collision point in a space, wherein the resulting emulsion is discharged from the space through an outlet. By the collision of the liquid streams with high flow velocities, in which a plate-shaped collision plate is formed in the collision point, a homogenous emulsion having an oil droplet size of less than 1 ?m is achieved due to the kinetic energy, which is accordingly very stable as well. No further energy input, such as shear forces, is required to that end.

Abstract: A microbicidally coated article, especially a container, having on at least part of it a coating comprising an organically modified inorganic matrix comprising silver colloids which is obtainable by application of a coating composition comprising a) a hydrolysate or condensate based on at least one hydrolysable silane with at least one non-hydrolysable substituent and b) a silver compound to the surface of the article and treatment with heat and/or radiation to form the silver colloid coating. Articles coated in accordance with the invention are therefore particularly suitable for purposes of disinfection, preservation, cosmetic, pharmaceutical or medical purposes. Articles from the pharmaceutical or medical sector, especially containers for pharmaceuticals or articles or components which come into contact with the human body and are required to be free from germs, are preferred fields of application.

Abstract: Components are separated from liquid or gaseous media with the aid of a nanocomposite comprising nanoparticles in a matrix, wherein the liquid or gaseous medium is brought into contact with the nanocomposite in such a way that at least part of the components to be separated off is bound to the nanocomposite and the resulting laden nanocomposite is separated from the liquid or gaseous medium.

Abstract: The invention relates to a method for coating a substrate according to which a self-crosslinking coating composition is produced on the basis of a) at least one hydrolysable silane with at least one nonhydrolysable substituent, said silane having one or more electrophilic groups X on at least one nonhydrolysable substitutent, b) at least one hydrolysable silane with at least one nonhydrolysable substituent, said silane having one or more nucleophilic groups Y on at least one nonhydrolysable substituent, c) at least one hydrolysable silane with at least one nonhydrolysable carbonic group that has an average of 2 to 30 fluorine atoms that are bound to one or more aliphatic carbon atoms that are separated from the silicon atom by at least two atoms.

Abstract: A process for preparing a composition for producing nanostructured mouldings and layers comprises contacting an aqueous and/or alcoholic sol of a compound of an element selected from silicon sand metals of the main groups and transition groups of the Periodic Table with species possessing hydrolysable alkoxy groups and comprising at least one organically modified alkoxysilane or a precondensate derived therefrom, under conditions which lead to (further) hydrolysis of the species, and subsequent removal of the alcohol formed and any alcohol already present originally. The process is characterized in that the alcohol is removed in an amount such that the residual alcohol content of the composition is not more than 20% by weight.
