  • Patent number: 8373139
    Abstract: Functionalized fullerenes, when excited at any of a broad range of wavelengths in an oxygen free environment, undergo luminescence. The oxygen sensitive luminescence of functionalized fullerenes is used for numerous applications including oxygen detection; irradiation induced healing of polymeric materials; and phosphors for optical location and display applications. The degradation of the functionalized fullerenes allows for the detection of oxygen by diminished luminescence when the fullerenes are exposed to an irradiation source, such as a laser beam, in the presence of oxygen. The luminescence from a portion of a surface of a material with functionalized fullerenes allows for the location of the surface containing a functionalized fullerene target in the absence of oxygen or to heat the object in the area irradiated that is exposed to oxygen. The localized heating can be used to repair defects to a material containing the functionalized fullerenes.

  • Publication number: 20120123182
    Abstract: An electromagnetic radiation activated device comprises a property changing material and at least one functionalized fullerene that upon irradiation of the functionalized fullerenes with electromagnetic radiation of one or more frequencies a thermally activated chemical or physical transformation occurs in the property changing material. The thermal activated transformation of the property changing material is triggered by the heating or combustion of the functionalized fullerenes upon their irradiation. The device can include a chemical agent that is embedded in the property changing material and is released when the material is heated by the functionalized fullerenes upon irradiation.

  • Publication number: 20120054027
    Abstract: A network based advertisement system includes an optimizer configured to forecast a supply of opportunities, forecast a supply of guaranteed contracts, and forecast a supply of non-guaranteed contracts. Each opportunity represents a user visiting a webpage. Each guaranteed contract guarantees the matching of an advertisement to a number of opportunities. Each non-guaranteed contract guarantees a user event associated with an advertisement. The optimizer then generates a plan for matching contracts to opportunities based on the forecasted supply of opportunities, the forecasted supply of guaranteed contracts, the forecasted supply of non-guaranteed contracts, and an objective function that balances a group of parameters that define the representativeness of contracts, a cost associated with not serving non-guaranteed contracts, and performance objectives associated with contracts.

  • Publication number: 20120015045
    Abstract: Functionalized fullerenes are used in a method of combating fungal growth on surfaces and treating fungal diseases of patients. Surfaces that can be treated by the materials comprising an effective amount of functionalized fullerenes include those of fruits, vegetables, harvested grains, plants, or plant seeds. The method of combating fungal growth on a surface can be augmented but is not dependent on irradiation of the surface by light. Functional fullerenes are employed in various dosage forms such as topical, ingestible or administration.

  • Publication number: 20120005018
    Abstract: A computer-implemented method for matching a display advertisement to a user within a large-scale, non-destructive user modeling and experimentation environment using real-time traffic. The method commences by populating a user profile object (containing demographics, history, and behaviors of the user) for use during concurrent operation of a production platform and an experimentation platform. To implement non-destructive testing, the method continues by cloning a portion of the real-time traffic for use by the experimentation platform while concurrently delivering the real-time traffic to the production platform. The production platform and the experimentation platform operate concurrently, scoring matches between the user profile objects and a plurality of display advertisements for selecting among the best-scored advertisements.

  • Publication number: 20110262340
    Abstract: Electromagnetic irradiation of functionalized fullerenes in an oxygen-free environment induces conversion of the functionalized fullerenes to carbon nanotubes, carbon nanohorns, carbon onions, diamonds and/or carbon schwarzites. The carbon nanotubes can be multi-wall carbon nanotubes. Advantageously, the subject invention can be used for in-situ synthesis of carbon nanostructures within a matrix to form a carbon nanostructure composite, where positioning of the carbon nanostructures is controlled by the manner of dispersion of the functionalized fullerenes in the matrix. Carbon nanotube comprising features, such as electrical connects, can be formed on a surface by irradiating a portion of a functionalized fullerene coating with a laser beam.

  • Publication number: 20110112232
    Abstract: Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PRFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.
