  • Patent number: 8384628
    Abstract: A document including an integrated display device that has several triggerable display elements, each of which is designed to emit an optical signal for representing first data stored in the document whereby the display device is designed for cyclical activation of the display elements for rendering the first data in sequential image regeneration periods, and whereby the display device is designed in such a way that the emission of the optical signals of at least a subset of the display element takes place with a chronological delay, whereby it is not possible to visually perceive the chronological delay.

  • Publication number: 20100267196
    Abstract: Nanocrystals that include a core/shell structure in which the a core of semiconductor material is coated with an inorganic capping agent. The nanocrystals are made by initially providing nanocrystal precursors that include a solubility agent which renders the precursors soluble in an organic solvent. The nanocrystal precursors are then coated with the inorganic capping agent in the presence of an organic solvent.
