Abstract: The technology provided herein relates to novel variants of microbial glucose oxidase with improved properties, more specifically to polypeptides having glucose oxidase activity as their major enzymatic activity; to nucleic acid molecules encoding the glucose oxidases; vectors and host cells containing the nucleic acids and methods for producing the glucose oxidase; compositions comprising the glucose oxidase; methods for the preparation and production of such enzymes; and to methods for using such enzymes for food and feed processing, for the measurement of free glucose in clinical samples and bioreactors, and the development of miniature biofuel cells.

Abstract: The present invention relates to a coating system comprising a layer of carbon nanotubes aligned parallel to another, and a directly linked surface layer with metallic properties, from which said carbon nanotubes are grown in “tip” growth. The coating system may further comprise a base layer and/or a substrate. It can be obtained by producing a structured layer from a first phase, consisting of a metal having no independent catalytic activity in terms of the emergence of CNTs from the gas phase, and a second phase consisting of a metal, which catalyzes the emergence of CNTs from the gas phase, on a substrate or a base layer, wherein the first phase has an uneven thickness and/or folded structure potentially interspersed with pores, and the second phase is located in depressions and/or pores of the initial phase in such a way that both material phases are present at least partially next to each other in the lateral plane on said substrate or said base layer located thereon.

Abstract: An ultrasonic sensor for detecting and/or scanning an object includes a substrate and a piezoelectric sensor unit arranged on or at this substrate and/or connected to this substrate. The rear side of the substrate facing away from the piezoelectric sensor unit has a surface structure including a plurality of elevated portions and recesses, with this surface structure being configured so that a diffuse scattering of ultrasonic waves incident on the rear side from the direction of the sensor unit takes place by it; and/or in that its elevated portions and/or recesses have a mean lateral extent in the range of 0.05 ?m to 1 mm, preferably from 0.1 ?m to 200 ?m, preferably from 0.2 ?m to 20 ?m, and/or a mean lateral extent which is smaller than or equal to the wavelength of an ultrasonic wave which can be produced by the piezoelectric sensor unit.

Abstract: The present invention relates to a method for producing fluorocarbon layers on a substrate, e.g., a metal, polymer, ceramic material and/or textiles by means of a low-pressure plasma method and products produced in this way.
