  • METHOD FOR UNIQUE MARKING AND IDENTIFICATION OF PRODUCTS
    Publication number: 20240190161
    Abstract: The present invention relates to a method for unique marking and to a method for the identification of products by identifying production inaccuracies in the spectral range of up to 3000 nm and to the use of said method for the unique identification of products/documents in serialization systems and/or track and trace systems and for document authentication. In order to increase the number of production inaccuracies up to a spectral range of up to 3000 nm, photoluminescent materials which, under photon excitation, emit radiation in the range of up to 3000 nm, preferably in the range of 750 to 1800 nm, most preferably in the range of 800 to 1100 nm, can be used. Said photoluminescent materials make it possible for production inaccuracies to be sensed from the spectral range of visible light (380 to 750 nm), via the near-infrared (NIR) range, to a spectral range of up to 3000 nm.

  • OPTICAL SECURITY FEATURE SUITABLE FOR TRACK-AND-TRACE AND/OR SERIALIZATION SYSTEMS
    Publication number: 20240051327
    Abstract: The present invention relates to a method for identifying products with the aid of an ink formulation which contains semiconductive inorganic nanocrystals which emit radiation in the range of 750-1800 nm when excited by photons, in serialisation and/or track-and-trace systems.

  • Polymer dye and method for producing the same and its use in light-emitting diodes and other optical components
    Patent number: 7288605
    Abstract: A method and apparatus for the removal of free, emulsified, or dissolved water from liquids of low volatility, such as oil, is shown. The liquid of low volatility is removed by contacting the fluid stream of concern with one side of a semi-permeable membrane. The membrane divides a separation chamber into a feed side into which the stream of fluid is fed, and a permeate side from which the water is removed. The permeate side of the chamber is maintained at a low partial pressure of water through presence of vacuum, or by use of a sweep gas.
