Silica aerogel synthesis methods are described. A solar thermal aerogel receiver (STAR) may include an opaque frame defining an opening, an aerogel layer disposed in the opaque frame, with at least a portion of the aerogel layer being proximate the opening, and a heat transfer fluid pipe in thermal contact with and proximate the aerogel layer. A concentrating solar energy system may include a STAR and at least one reflector to direct sunlight to an opening in the STAR.Type: ApplicationFiled: November 14, 2023Publication date: May 9, 2024Inventors: Gang Chen, Evelyn N.

Patent number: 11978430Abstract: A programmable metasurface and method is described having a plurality of parallel slits in an elastic substrate plate defining a plurality of unit cells, each having an actuator beam and a sensing beam with a slit therebetween. Each sensing beam has a pair of sensors for sensing flexural waves in the substrate. The actuator beam has a piezoelectric actuator that is controlled by a control circuit where the control circuit generates an actuator signal and where the control circuit compares the preceding actuator signal to the difference between the sensors and an electrical transfer function to result in the metasurface being able to perform a desired function.Type: GrantFiled: September 16, 2019Date of Patent: May 7, 2024Assignee: The Curators of the University of MissouriInventors: Guoliang Huang, Yangyang Chen, Xiaopeng Li

Patent number: 10756811Abstract: A target receives two signals of different modes in association with a first location and another two signals in association with a second location. The first two signals are assumed to have been emitted effectively simultaneously from the first location, and the second two signals are assumed to have been emitted effectively simultaneously from the second location. A first distance is calculated in view of a receipt time difference of the first two signals in view of differing rates of propagation assumed between these two signals; a second distance is calculated in view of another receipt time difference of these second two signals in view of differing rates of propagation assumed between each of these other signals. A possible location of the target is then calculated in view of the first distance and its associated first location and the second distance and its associated second location.Type: GrantFiled: March 30, 2018Date of Patent: August 25, 2020Inventors: Mohsen Sarraf, Xiaopeng Huang, Walid Khairy Mohamed Ahmed

Patent number: 10427345Abstract: Process for continuous fabrication of highly aligned polymer films. A polymer-solvent solution is subjected to a high shear, high temperature, Couette flow to extrude a thin film having polymer chain disentanglement. The extruded thin film is frozen and the solvent is allowed to evaporate to form a dried film. The dried film is mechanically drawn using a constant force, adaptive-thickness drawing system to align polymer molecular chains through plastic deformation. A suitable polymer is ultra-high molecular weight polyethylene.Type: GrantFiled: April 30, 2015Date of Patent: October 1, 2019Assignee: Massachusetts Institute of TechnologyInventors: Gang Chen, Jianjian Wang, Jonathan Kien-Kwok Tong, Hadi Ghasemi, Xiaopeng Huang, James Loomis, Yanfei Xu
