Patent number: 9950977Abstract: 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 PHFs 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.Type: GrantFiled: June 22, 2015Date of Patent: April 24, 2018Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Vijay Krishna, Brij M.

Patent number: 8373139Abstract: 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.Type: GrantFiled: January 5, 2009Date of Patent: February 12, 2013Assignee: University of Florida Research Foundation, Inc.Inventors: Vijay Krishna, Brij M.
