  • Systems and methods for forming defects on graphitic materials and curing radiation-damaged graphitic materials
    Patent number: 8273525
    Abstract: Systems and methods are disclosed herein for forming defects on graphitic materials. The methods for forming defects include applying a radiation reactive material on a graphitic material, irradiating the applied radiation reactive material to produce a reactive species, and permitting the reactive species to react with the graphitic material to form defects. Additionally, disclosed are methods for removing defects on graphitic materials.
    Type: Grant
    Filed: April 29, 2010
    Date of Patent: September 25, 2012
    Assignee: The Trustees of Columbia University in the City of New York
    Inventors: Sunmin Ryu, Louis E. Brus, Michael L. Steigerwald, Haitao Liu

  • Chemical processing using electromagnetic field enhancement
    Patent number: 4481091
    Abstract: The use of induced electromagnetic field enhancement to improve chemical processing is disclosed. Shape, image and resonant polarizability phenomena are used to obtain regions of increased field intensities where atomic and/or molecular interactions are advantageously affected to yield improved or increased chemical processing.

  • Reflective containment of electromagnetic radiation in matrix isolation thin films
    Patent number: 4448524
    Abstract: Efficient transmission of light through a matrix isolation thin film is obtained despite the fact that the index configuration of the thin film is not appropriate for classical waveguides. The light is transmitted through the film approximately parallel to the substrate, thereby permitting analysis of the thin film, stimulation of reaction within the thin film, or use of the thin film as an optical memory.
