Publication number: 20240018388Abstract: Durable antibacterial coatings are prepared by inter-diffusing zwitterionic polyurethane in acrylic polyurethane. Bacterial attachment is substantially eliminated from the surface of the coatings due to the hydrophilicity of the zwitterionic polyurethane. Long-term antibacterial properties were observed for both Gram-negative and Gram-positive bacteria even when the coatings were constantly challenged by mechanical abrasion.Type: ApplicationFiled: September 12, 2023Publication date: January 18, 2024Applicant: University of Houston SystemInventors: Hadi Ghasemi, Zixu Huang

Publication number: 20220228022Abstract: Winter icing can adversely impact transportation systems (aircrafts, drones, trains, etc.), infrastructure, and energy systems, among many other things. Existing ice-shedding coatings generally suffer from low durability under various mechanical, chemical, and environmental stresses. The polyurethane-based, stress-localized ice-shedding coatings described herein present a novel material paradigm to develop highly durable ice-shedding coatings capable of withstanding harsh aerospace and other industrial conditions. By optimizing the chemical composition and processing of the coating, a uniform, highly durable, polyurethane-based ice-shedding coating has been achieved that can be applied to a variety of surfaces. These coatings have been comprehensively tested, including ice adhesion strength measurements, ice-shedding capabilities in an icing wind tunnel, and a set of mechanical, chemical and environmental durability tests.Type: ApplicationFiled: January 19, 2022Publication date: July 21, 2022Inventors: Hadi Ghasemi, Brian Huskinson, Sahar Qavi

Patent number: 11302467Abstract: Modified surfaces of the present disclosure include a surface or substrate material, a magnetic field, which may be generated through the use of a magnet placed at a distance beneath the surface or substrate, or placed above the surface or substrate, or through the use of a magnetic surface or substrate, and a magnetic fluid, such as ferrofluid or ferrogel, deposited in a layer on the top of the surface or substrate. The modified surfaces may be icephobic. In addition, a droplet of liquid placed on the modified surface can be manipulated through placement of a local heat source in proximity to the droplet, without contacting the droplet.Type: GrantFiled: March 21, 2017Date of Patent: April 12, 2022Assignee: UNIVERSITY OF HOUSTON SYSTEMInventors: Hadi Ghasemi, Peyman Irajizad, Munib Hasnain

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

Patent number: 10043932Abstract: A single-stack, solar power receiver comprising both a thermal absorber layer and a photovoltaic cell layer. The stack includes an aerogel layer, that is optically transparent and thermally insulating (“OTTI”); a spectrally selective high thermal conductivity (“SSTC”) thermal absorber layer; a bottom OTTI layer; and a PV cell layer. The SSTC layer includes a set of fins that substantially blocks solar radiation absorption in the band where PV cells are most sensitive. Photons with energies above or below this band block range are absorbed by the fins and the absorbed heat is conducted to pipes in the fin structure carrying a heated thermal working fluid to heat storage. Photons with energy in the band block range are reflected by the SSTC fins to the PV cell layer. The bottom OTTI aerogel layer keeps the PV cell operating near ambient temperature. The PV cell converts incident solar radiation to electrical energy.Type: GrantFiled: August 20, 2014Date of Patent: August 7, 2018Assignee: Massachusetts Institute of TechnologyInventors: Gang Chen, Evelyn N.

Patent number: 9559388Abstract: Electrochemical systems for harvesting heat energy, and associated electrochemical cells and methods, are generally described. The electrochemical cells can be configured, in certain cases, such that at least a portion of the regeneration of the first electrochemically active material is driven by a change in temperature of the electrochemical cell. The electrochemical cells can be configured to include a first electrochemically active material and a second electrochemically active material, and, in some cases, the absolute value of the difference between the first thermogalvanic coefficient of the first electrochemically active material and the second thermogalvanic coefficient of the second electrochemically active material is at least about 0.5 millivolts/Kelvin.Type: GrantFiled: June 18, 2014Date of Patent: January 31, 2017Assignees: Massachusetts Institute of Technology, The Board of Trustees of the Leland Staford Junior UniversityInventors: Seok Woo Lee, Yuan Yang, Hadi Ghasemi, Gang Chen, Yi Cui
