Abstract:
A process for a consolidation which is hydrolytically stable under hydrothermal conditions and/or for changing the wetting behavior of a porous and/or particulate geological formation. The process comprises introducing into the geological formation a consolidant and curing the introduced consolidant under elevated pressure and elevated temperature. The consolidant comprises a hydrolyzate and/or a precondensate based on silanes and metal compounds.
Abstract:
Disclosed is a substrate with an abrasion resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or semimetal oxide. The coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide or semimetal oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment.The inventive coating is suitable for optical layers, particularly on translucent substrates. Examples of adequate uses include antireflection layers and interference layer assemblies.
Abstract:
The invention relates to a method for microstructuring electronic components, which yields high resolutions (≦200 nm) at a good aspect ratio while being significantly less expensive than photolithographic methods. The inventive method comprises the following steps: i) a planar unhardened sol film of a nanocomposite composition according to claim 1 is produced; ii) a target substrate consisting of a bottom coat (b) and a support (c) is produced; iii) sol film material obtained in step i) is applied to the bottom coat (b) obtained in step ii) by means of a microstructured transfer embossing stamp; iv) the applied sol film material is hardened; v) the transfer embossing stamp is separated, whereby an embossed microstructure is obtained as a top coat (a). The method for producing a microstructured semiconductor material comprises the following additional steps: vi) the remaining layer of the nanocomposite sol film is plasma etched, preferably with CHF3/O2 plasma; vii) the bottom coat is plasma etched, preferably with O2 plasma; viii) the semiconductor material is etched or the semiconductor material is doped in the etched areas.

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.
