Patent number: 10525419Abstract: An oil-water separation membrane is described. The oil-water separation membrane comprises a porous metal sheet with a photocatalyst layer on one side and a layer of nanoparticles and a surfactant on the other side. The layer of nanoparticles and surfactant create a superoleophobic and superhydrophilic coating that allows passage of an aqueous phase and rejection of an oil phase. The photocatalyst layer, combined with UV irradiation, enables degradation of organic contaminants in the aqueous phase. The oil-water separation membrane may be used as part of an oil-water separation system, and a filtered water product may be recycled through the membrane to increase the removal of organic contaminants.Type: GrantFiled: October 26, 2017Date of Patent: January 7, 2020Assignees: King Fahd University of Petroleum and Minerals, MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Talal F. Qahtan, Leonardo D. Banchik, Mohammed A. Gondal, Gibum Kwon, Divya Panchanathan, Umair Baig, Gareth McKinley, Mohamed A. Dastageer

Patent number: 10307760Abstract: One example of systems and methods for inertio-elastic focusing of particles in microchannels includes a substrate including a channel having an inlet and an outlet. A viscoelastic fluid, i.e., a fluid having a dynamic viscosity that varies with shear rate, and that carries suspended particles is driven through the channel. The volumetric flow rate at which the fluid is driven results in the formation of a localized pathline in the fluid at or near a center of the channel. The localized pathline defines a width that is equal to or slightly greater than a hydraulic diameter of the particle. The particles in the fluid are focused into the localized pathline.Type: GrantFiled: January 30, 2015Date of Patent: June 4, 2019Assignees: The General Hospital Corporation, Massachusetts Institute of TechnologyInventors: Mehmet Toner, Gareth McKinley, Eugene Lim, Thomas Ober

Patent number: 9289302Abstract: Various embodiments of mosaicplasty constructs and methods for implanting the constructs into anatomical structures. The mosaicplasty constructs may be formed from artificial materials and may include a hard articulating portion and a relatively softer elastic, support portion. The mosaicplasty constructs may include bone ingrowth materials to facilitate ingrowth of bone and other tissues into the construct. The mosaicplasty constructs may also be at least partially formed of hydrogel materials.Type: GrantFiled: July 20, 2009Date of Patent: March 22, 2016Assignee: Zimmer, Inc.Inventors: Brian H. Thomas, Steven J. Charlebois, Donald Yakimicki, James Mason, Stephen H. Spiegelberg, Gavin Braithwaite, Gareth McKinley, Orhun Muratoglu

Publication number: 20080090933Abstract: The present invention provides an irradiated crosslinked polyethylene containing reduced free radicals, preferably containing substantially no residual free radical. Disclosed is a process of making irradiated crosslinked polyethylene by irradiating the polyethylene in contact with a sensitizing environment at an elevated temperature that is below the melting point, in order to reduce the concentration of residual free radicals to an undetectable level. A process of making irradiated crosslinked polyethylene composition having reduced free radical content, preferably containing substantially no residual free radicals, by mechanically deforming the polyethylene at a temperature that is below the melting point of the polyethylene, optionally in a sensitizing environment, is also disclosed herein.Type: ApplicationFiled: October 17, 2007Publication date: April 17, 2008Applicants: Massachusetts General Hospital, Cambridge Polymer Group, Inc.Inventors: Orhun Muratoglu, Stephen Spiegelberg, Gareth McKinley

Publication number: 20080009568Abstract: A method of dispersing particles in a medium. The method includes providing a first particle/solvent dispersion comprising the particles and a first solvent, adding a second solvent to the first particle/solvent dispersion to form a second particle/solvent dispersion, wherein the first solvent and the second solvent are miscible, and extracting substantially all of the first solvent from the second particle/solvent dispersion to form a third particle/solvent dispersion.Type: ApplicationFiled: October 18, 2005Publication date: January 10, 2008Inventors: Nitin Kumar, Shawna Liff, Gareth McKinley

Publication number: 20070107778Abstract: An impact absorber employs dilatant (shear responsive) fluid that is subjected to a controlled, low amplitude, high frequency oscillatory stress which controls the stiffness of the fluid. Piezoelectric transducers, voice coils, and other forms of transducers may be used to apply controlled vibratory stress to the fluid. The energy absorber may be used in protective body armor, medical devices such as splints and casts, vehicle safety absorbers and many other products which benefit from ability to control the stiffness of the energy absorber.Type: ApplicationFiled: November 12, 2005Publication date: May 17, 2007Applicant: Massachusetts Institute of TechnologyInventors: Giorgia Bettin, Suraj Deshmukh, Gareth McKinley
