Patent number: 11716990Abstract: Systems and methods related to the formation of a reaction product on a surface are generally provided. The systems and methods described herein may allow for collection of the retention of a fluid by a surface in a relatively high amount. Such systems and methods may be useful in various applications including, for example, agriculture. In some embodiments, the systems and methods enhance water retention on hydrophobic surfaces of plants. Advantageously, the methods described herein may, in some cases, result in the formation of reaction products on a surface that serve to prevent fluids from being removed from the surface. Advantageously, the systems and methods described herein may suppress the adverse effects of natural conditions such as high surface energies and wind.Type: GrantFiled: December 16, 2020Date of Patent: August 8, 2023Assignee: Massachusetts Institute of TechnologyInventors: Kripa K. Varanasi, Maher Damak, Seyed Reza Mahmoudi, Nasim Hyder

Patent number: 11499116Abstract: A low friction coated article includes a first structure that has a first lubricated surface coated with a first polyelectrolyte coating. A second structure has a second lubricated surface with a second polyelectrolyte coating opposite the first lubricated surface. The first and second polyelectrolyte coatings include alternating layers of positively charged polyelectrolyte layers and negatively charged polyelectrolyte layers hydrated with a lubricant.Type: GrantFiled: December 17, 2019Date of Patent: November 15, 2022Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Seyed Reza Mahmoudi, Catalin G. Fotache

Patent number: 11079141Abstract: A method for precise control of movement of a motive phase on a lubricant-impregnated surface includes providing a lubricant-impregnated surface, introducing the motive phase onto the lubricant-impregnated surface, and exposing the droplets to an electric and/or magnetic field to induce controlled movement of the droplets on the surface. The lubricant-impregnated surface includes a matrix of solid features spaced sufficiently close to stably contain the impregnating lubricant therebetween or therewithin. The motive phase is immiscible or scarcely miscible with the impregnating lubricant.Type: GrantFiled: April 18, 2018Date of Patent: August 3, 2021Assignee: Massachusetts Institute of TechnologyInventors: Karim Samir Khalil, Kripa K. Varanasi, Seyed Reza Mahmoudi

Publication number: 20210220838Abstract: Systems and methods related to the collection of a species from a gas stream are generally provided. The systems and methods described herein may allow for collection of a species such as a fluid (e.g., water) with a relatively high collection efficiency. Such systems and methods may be useful in various applications including, for example, fog collection. In some embodiments, the systems and methods enhance water collection from airborne fog to produce usable water. Advantageously, the methods described herein may, in some cases, incorporate ions into the gas stream such that the species present in the gas stream follows electric field lines and/or are attracted to a grounded (or charged) collector. Advantageously, the systems and methods described herein may suppress the adverse effects of natural conditions such as the velocity and direction of the wind.Type: ApplicationFiled: December 3, 2020Publication date: July 22, 2021Applicant: Massachusetts Institute of TechnologyInventors: Maher Damak, Seyed Reza Mahmoudi, Kripa K.

Publication number: 20190209949Abstract: Embodiments discussed herein relate to systems and methods for separating two or more phases of an emulsion or other mixture. The methods include providing the mixture with a net and unipolar charge (e.g., such that adjacent droplets therein acquire net and unipolar charges), thereby enhancing coalescence of like-phase droplets therein and producing, or enhancing the production of, two or more consolidated phases; and collecting the two or more consolidated phases.Type: ApplicationFiled: November 5, 2018Publication date: July 11, 2019Inventors: Seyed Reza Mahmoudi, Kripa K.
