  • Patent number: 11460390
    Abstract: In order to permit a robust, energy-efficient and precise moisture sensor, the invention relates to a moisture sensor element (10) for a moisture sensor (12) for measuring a moisture content in a gas, comprising at least one vibrating element (14) and at least one material (16, 18) on the vibrating element (14), wherein the at least one material (16, 18) is designed in such a way that the mass thereof changes rapidly with moisture changing over a moisture value. The invention also relates to a moisture-measuring method for measuring a moisture in a gas, comprising: using a moisture sensor element (10), wherein the course of the measurement signal thereof has at least one non-linearity according to the moisture; and determining a reference value based on the at least one non-linearity.

  • Publication number: 20080233356
    Abstract: A roll coating method for preparing a coated substrate with structured surface of the coating is described. Said method comprises application of a polymer based coating fluid to a substrate surface by means of a coating fluid application roll and then curing the applied coating, wherein the polymer based coating fluid is a fluid showing Bingham or Herschel-Bulkley flow behavior with a yield stress ?0>10 dyn cm?2, in particular a fluid having low viscosity at high shear rate, fast viscosity enhancement in the absence of shear stress and a high yield stress. Applications of such produced surfaces are release films, e.g. for pressure sensitive adhesives, controlled release adhesives and self-cleaning surfaces and friction coefficient reducing surfaces.

  • Patent number: 7211236
    Abstract: Described is a method for the production of metal oxides by flame spray pyrolysis, in particular mixed metal oxides such as ceria/zirconia, and metal oxides obtainable by said method. Due to high enthalpy solvents with a high carboxylic acid content said metal oxides have improved properties. For example ceria/zirconia has excellent oxygen storage capacity at high zirconium levels up to more than 80% of whole metal content.
