Patent number: 9314027Abstract: 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.Type: GrantFiled: April 1, 2010Date of Patent: April 19, 2016Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Vijay Krishna, Brij M. Moudgil, Benjamin L. Koopman

Publication number: 20150284309Abstract: 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: ApplicationFiled: June 22, 2015Publication date: October 8, 2015Inventors: VIJAY KRISHNA, BRIJ M. MOUDGIL, BENJAMIN L. KOOPMAN

Patent number: 8974644Abstract: 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.Type: GrantFiled: April 2, 2014Date of Patent: March 10, 2015Assignee: University of Florida Research Foundation, Inc.Inventors: Vijay Krishna, Brij M.

Patent number: 8839031Abstract: Data consistency between a primary virtual machine and a recovery virtual machine may employ a resync engine to detect differences in data blocks stored on both virtual machines. For example, the resync engine may calculate a signature (e.g., hash value) for a primary data block and a corresponding signature for a recovery data block, and compare the signature and the corresponding signature to identify a difference between the primary data block and the recovery data block. In some instances, by identifying a difference between the primary data block and the recovery data block, a data block (e.g., primary data block or recovery data block) may be identified to be transferred from a virtual machine to another virtual machine.Type: GrantFiled: April 24, 2012Date of Patent: September 16, 2014Assignee: Microsoft CorporationInventors: Partho P.
