  • Patent number: 8139901
    Abstract: A method and system for nano-encoding and decoding information related to printed texts and images on paper and other surfaces is provided. The system and method includes a nano-encoder for encoding information related to printed texts and images; and then collocating the encoded information with the related printed texts and/or images. The system also includes a nano-decoder for decoding information encoded by the nano-encoder. The nano-decoder includes a text processing database having a translator database. The translator database includes a definition database; and a summary database. In addition, the system and method includes detecting luminescent nano particles and/or magnetic nano particles; and determining invariant properties of the detected nano particles. The invariant properties are then matched with coded information.

  • Patent number: 7964481
    Abstract: An inorganic nanocomposite is prepared by obtaining a solution of a soluble hydrazine-based metal chalcogenide precursor; dispersing a nanoentity in the precursor solution; applying a solution of the precursor containing the nanoentity onto a substrate to produce a film of the precursor containing the nanoentity; and annealing the film of the precursor containing the nanoentity to produce the metal chalcogenide nanocomposite film comprising at least one metal chalcogenide and at least one molecularly-intermixed nanoentity on the substrate. The process can be used to prepare field-effect transistors and photovoltaic devices.
