Patent number: 9999858Abstract: Methods for making multiple walled nested coaxial nanostructures and devices incorporating the coaxial nanostructures are disclosed. The coaxial nanostructures include an inner nanostructure, a first outer nanotube disposed around the inner nanostructure, and a first annular channel between the inner nanostructure and the first outer nanotube. The coaxial nanostructures have extremely high aspect ratios, ranging from about 5 to about 1,200, or about 300 to about 1200.Type: GrantFiled: November 13, 2014Date of Patent: June 19, 2018Assignee: OLD DOMINION UNIVERSITY RESEARCH FOUNDATIONInventors: Helmut Baumgart, Gon Namkoong, Diefeng Gu, Tarek Abdel-Fattah

Publication number: 20120278929Abstract: The present invention presents methods to alter the genetic composition of crop plants susceptible to nematode infection to improve tolerance to the same. Methods and compositions for modulating key pathways involved in the syncytial event of nematode infection and for preventing the cascade of differential gene expression caused by the same as disclosed. Applicants have found that the microRNA miR396 acts as a master switch of syncytial gene expression changes in plants after infection, and further that miR396 and certain growth regulating transcription factors (GRF) are connected through feedback interaction in syncytium initiation and maintenance.Type: ApplicationFiled: April 27, 2012Publication date: November 1, 2012Applicant: IOWA STATE UNIVERSITY RESEARCH FOUNDATION, INC.Inventors: Thomas J. Baum, Tarek Abdel Fattah Hewezi

Publication number: 20120080313Abstract: Electroosmotic (EO) devices are provided which are not subject to mechanical wear and tear and with no moving parts, and having improved flow rates and electrical properties. Atomic layer deposition can be used to prepare three electrical terminal active zeta potential modulated EO devices from porous membranes. First, second, and further thin layers of materials can be formed with the pores. Thus, embedded electrodes can be formed along the length of the pores. The zeta potential in the pores can be modified by use of a voltage potential applied the embedded electrode, thereby achieving active control of surface zeta potential within the pores and active control of flow through the pores.Type: ApplicationFiled: October 24, 2011Publication date: April 5, 2012Applicant: Old Dominion University Research FoundationInventors: Helmut BAUMGART, Diefeng Gu, Tarek Abdel-Fattah, Ali Beskok, Seungkyung Park

Publication number: 20110168955Abstract: A method of growing carbon nanotubes uses a synthesized mesoporous silica template with approximately cylindrical pores being formed therein. The surfaces of the pores are coated with a carbon nanotube precursor, and the template with the surfaces of the pores so-coated is then heated until the carbon nanotube precursor in each pore is converted to a carbon nanotube.Type: ApplicationFiled: January 30, 2007Publication date: July 14, 2011Applicant: USA as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Tarek Abdel-Fattah, Emilie J. Siochi

Patent number: 7915475Abstract: A novel method for remediating metals includes treating the metals with a mesoporous nanocomposite such as HMS, MCM-41 or MCM-48. The metal is preferably lead but can be at least one metal selected from Pb, Hg, Cd, Zn, Sn, As, Sb, In, Se, Ga, Te, Bi, Ni, Cu, Mo, Ni, Cu, Sr, Ba or Co. The treating is preferably performed at a pH of about 4 to about 12. In the invention, the treating can also include desorbing the metal from the mesoporous nanocomposite at a pH of about 2 or less.Type: GrantFiled: July 2, 2004Date of Patent: March 29, 2011Assignee: Christopher Newport UniversityInventors: Tarek Abdel-Fattah, Larry K. Isaacs

Publication number: 20100212219Abstract: A method for purifying a biodiesel fuel includes the use of subjecting a biodiesel fuel to an electric field. The electric field forms a precipitate in the fuel that removes the impurities of excess catalysts and soap that are byproducts of the reaction that forms the biodiesel. This electric field assisted washing process can be applied to a biodiesel fuel in a batch process or, alternatively, in a continuous process.Type: ApplicationFiled: September 11, 2009Publication date: August 26, 2010Applicant: USA as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Emilie J.
