Provided is a process for producing a structured surface possessing a high level of hydrophilicity, wherein the process involves: coating a surface with a mixture to produce the structured surface, wherein the mixture includes: particles (a) having a number average particle diameter of from 0.1 &#x3bc;m to 10 &#x3bc;m; and particles (b) having a number average particle diameter of from 5 nm to 0.5 &#x3bc;m and a 20&#xb0; C. surface energy of greater than or equal to 80 mN/in, and wherein the mixture exhibits a bimodal particle diameter distribution of particles (a) and particles (b). The mixture may optionally include an aqueous liquor, an emulsifier, a binder, an adhesion promoter, a thickener, and/or a pigment. Also provided is a structured surface produced by the process. A non-limiting example of the structured surface produced by the process is a structured textile surface.

Method for the production of structured surfaces

The present invention relates to wax formulations comprising a wax constituent a) plus at least one high molecular mass isobutene polymer b) in an amount of from 0.1 to 5 parts by weight per part by weight of constituent a).

In a miniaturizable, capacitively measuring chemical semiconductor-based sensor system consisting of a sensor and a reference element which are to be brought into contact with the electrolyte to be measured, the reference element being connected in series with the sensor, the reference element consists of a highly doped semiconductor substrate or metal/semiconductor substrate which is covered with a membrane, and the sensor consists of an insulator/semiconductor substrate which is coated with a sensitive membrane, and the sensitive membrane of the sensor is more sensitive than that of the reference element. The sensor and the reference element of this sensor system may either be applied to one and the same chip or consist of individual components which are readily interchangeable with one another.
