  • Patent number: 7939303
    Abstract: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.

  • Patent number: 7939993
    Abstract: The present invention relates to a micromechanical HF switching element, in which a freestanding movable element is situated above a metallic surface on a substrate in such way that it is drawn to the metallic surface, to which a dielectric layer is applied, by applying an electrical voltage between the metallic surface and the movable element. The present invention also relates to a method for producing micromechanical HF switching elements of this type, in which the dielectric layer is deposited on the metal surface. The present method is distinguished in that a piezoelectric AlN layer having a columnar, polycrystalline structure and a texture is deposited on the metallic surface as the dielectric layer. Significantly reduced charging of the dielectric material and increased long-term stability of the switching element are achieved by the present method and the HF switching element thus produced.
