Patent number: 9120669Abstract: Fabrication method. At least first and second hardmasks are deposited on a substrate, the thickness and materials of the first and second hardmask selected to provided etch selectivity with respect to the substrate. A nanoscale pattern of photoresist is created on the first hardmask and the hardmask is etched through to create the nanoscale pattern on a second hardmask. The second hardmask is etched through to create the desired taper nanocone structures in the substrate. Reactive ion etching is preferred. A glass manufacturing process using a roller imprint module is also disclosed.Type: GrantFiled: April 13, 2012Date of Patent: September 1, 2015Assignee: Massachusetts Institute of TechnologyInventors: Hyungryul Choi, Chih-Hao Chang, Kyoo Chul Park, Gareth H McKinley, George Barbastathis, Jeong-gil Kim

Publication number: 20140336039Abstract: Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These TiO2 nanostructured surfaces are also anti-fogging, anti-bacterial, and compatible with flexible glass substrates and remain photocatalytically active in natural sunlight.Type: ApplicationFiled: May 9, 2014Publication date: November 13, 2014Applicant: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Robert E. COHEN, Michael F. RUBNER, Gareth H. MCKINLEY, George BARBASTATHIS, Hyungryul Johnny CHOI, Kyoo Chul PARK, Hyomin LEE

Publication number: 20140010994Abstract: Inverted Nanocone Structures and Its Fabrication Process. The method of fabricating nanotextured structures includes making a master mold having an array of tapered structures to be replicated. The master mold is pressed into a curable polymer supported on a substrate and the polymer is cured. Thereafter, the mold is detached from the cured polymer to form the nanotextured structure.Type: ApplicationFiled: July 1, 2013Publication date: January 9, 2014Applicant: Massachusetts Institute of TechnologyInventors: Hyungryul Choi, Jeong-gil Kim, Kyoo Chul Park, Robert E.

Publication number: 20120082860Abstract: 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: December 8, 2011Publication date: April 5, 2012Inventors: Orhun K. Muratoglu, Stephen H. Spiegelberg, Gareth H. Mckinley

Patent number: 8091692Abstract: An impact absorber using an energy-absorbing, fluid-impregnated material consisting of a porous interconnected network of solid material forming edges and faces of cells, preferably an open-cell reticulated or partially closed-cell foam, or formed from fibers or other cellular solids. The matrix is impregnated with a field responsive fluid such as a magneto- or electro-rheological fluid, or with a shear-rate responsive fluid such as a dilatant (shear-thickening) fluid. The material is placed under compression during impact, and may be housed within a cylinder and compressed by a piston. The stiffness of the composite material consisting of a matrix filled with a field responsive fluid can be controlled by varying the field intensity and spatial gradients of the applied field to vary the rheological properties of the fluid.Type: GrantFiled: March 3, 2003Date of Patent: January 10, 2012Assignee: Massachusetts Institute of TechnologyInventors: Suraj S. Deshmukh, Gareth H. McKinley

Patent number: 7896019Abstract: 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: GrantFiled: November 12, 2005Date of Patent: March 1, 2011Assignee: Massachusetts Institute for TechnologyInventors: Giorgia Bettin, Suraj S.
