Patent number: 8105754Abstract: A method for electron beam nanolithography without the need for development step involves depositing a film of a resist comprising functionalized fullerenes on a substrate, and writing features by exposure to an electron beam with an accelerating voltage and dose rate sufficient to promote heating or thermal degradation of the functionalized fullerene in the irradiated volume such that a pattern is generated without a subsequent development step or with an aqueous developer. Lithographic features of about 1 nm or greater can be formed.Type: GrantFiled: January 5, 2009Date of Patent: January 31, 2012Assignee: University of Florida Research Foundation, Inc.Inventors: Amit Kumar Singh, Vijay Krishna, Brij M.

Publication number: 20120015045Abstract: 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: ApplicationFiled: April 1, 2010Publication date: January 19, 2012Applicant: University of Florida Research Foundation, Inc.Inventors: Vijay Krishna, Brij M.

Publication number: 20120005018Abstract: 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.Type: ApplicationFiled: July 2, 2010Publication date: January 5, 2012Inventors: Vijay Krishna Narayanan, Rajesh Parekh, Albert Meltzer, Sharon Y.

Publication number: 20110262340Abstract: 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: ApplicationFiled: November 9, 2009Publication date: October 27, 2011Applicant: University of Florida Research Foundation Inc.Inventors: Vijay Krishna, Brij M.

Publication number: 20110112232Abstract: 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.Type: ApplicationFiled: June 24, 2009Publication date: May 12, 2011Inventors: Vijay Krishna, Brij M.

Patent number: 6810426Abstract: Integrated Bandwidth Latency Scheduler apparatus, method and system (collectively, IBLS) combines Fair Queuing and Priority Schedulers in a single stage to provide bandwidth fairness guarantees as well as latency prioritization. The IBLS includes a scheduler and process that dequeues packets from multiple queues in an order based upon an algorithm of the IBLS that arranges and dequeues those queues having the highest priority based on content therein. The IBLS also utilizes quotas and deficit counters to ensure that packets from each source receive their fair portion of the outgoing link bandwidth. To determine which first in first out queue an incoming data packet is placed, the enqueue agent utilized by the present invention classifies incoming packets based on the type of data included within the data packet, the source of the packet, the type of data flow, or another attribute of the packet, such as a header associated with the packet.Type: GrantFiled: January 30, 2002Date of Patent: October 26, 2004Assignee: Nomadix, Inc.Inventors: Manamohan D.
