Patent number: 10815129Abstract: A rigid radiation reflector is fabricated from a powdered material transparent to light in a wavelength band extending from approximately 0.2 micrometers to at least 8 micrometers. The powdered material is dispersed in a liquid wherein the powdered material is at least 95% insoluble in the liquid. The resulting mixture is molded under pressure at room temperature and then sintered to generate a porous solid. The porous solid is cooled to room temperature. A surface of the porous solid is then coated with a light-reflecting metal.Type: GrantFiled: August 29, 2018Date of Patent: October 27, 2020Assignee: United States of America as Represented by the Administrator of NASAInventors: Robert C. Youngquist, Tracy L. Gibson, Jan M. Surma, Jerry W. Buhrow, Mark A. Nurge

Patent number: 9233394Abstract: Hydrophobic-core microcapsules and methods of their formation are provided. A hydrophobic-core microcapsule may include a shell that encapsulates a hydrophobic substance with a core substance, such as dye, corrosion indicator, corrosion inhibitor, and/or healing agent, dissolved or dispersed therein. The hydrophobic-core microcapsules may be formed from an emulsion having hydrophobic-phase droplets, e.g., containing the core substance and shell-forming compound, dispersed in a hydrophilic phase. The shells of the microcapsules may be capable of being broken down in response to being contacted by an alkali, e.g., produced during corrosion, contacting the shell.Type: GrantFiled: August 13, 2010Date of Patent: January 12, 2016Assignee: The United States of America as Represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Luz M. Calle, Wenyan Li, Jerry W. Buhrow, Scott T. Jolley

Patent number: 9227221Abstract: Hydrophilic-core microcapsules and methods of their formation are provided. A hydrophilic-core microcapsule may include a shell that encapsulates water with the core substance dissolved or dispersed therein. The hydrophilic-core microcapsules may be formed from an emulsion having hydrophilic-phase droplets dispersed in a hydrophobic phase, with shell-forming compound contained in the hydrophilic phase or the hydrophobic phase and the core substance contained in the hydrophilic phase. The shells of the microcapsules may be capable of being broken down in response to being contacted by an alkali, e.g., produced during corrosion, contacting the shell.Type: GrantFiled: August 16, 2010Date of Patent: January 5, 2016Assignee: The United States of America as Represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Luz M. Calle, Wenyan Li, Jerry W. Buhrow, Scott T. Jolley

Patent number: 9108178Abstract: Elongated microcapsules, such as elongated hydrophobic-core and hydrophilic-core microcapsules, may be formed by pulse stirring an emulsion or shearing an emulsion between two surfaces moving at different velocities. The elongated microcapsules may be dispersed in a coating formulation, such as paint.Type: GrantFiled: January 20, 2012Date of Patent: August 18, 2015Assignee: The United States of America as Represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Luz M. Calle, Wenyan N. Li, Jerry W. Buhrow, Stephen A. Perusich, Scott T. Jolley, Tracy L. Gibson, Martha K. Williams

Patent number: 8859288Abstract: Methods to produce pH-sensitive microparticles that have an active agent dispersed in a polymer matrix have certain advantages over microcapsules with an active agent encapsulated in an interior compartment/core inside of a polymer wall. The current invention relates to pH-sensitive microparticles that have a corrosion-detecting or corrosion-inhibiting active agent or active agents dispersed within a polymer matrix of the microparticles. The pH-sensitive microparticles can be used in various coating compositions on metal objects for corrosion detecting and/or inhibiting.Type: GrantFiled: July 5, 2012Date of Patent: October 14, 2014Assignee: The United States of America as Represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Wenyan Li, Jerry W. Buhrow, Scott T. Jolley, Luz M. Calle
