Patent number: 11840459Abstract: The present disclosure is directed to variable composition ceramics. Zr(2?x)Hf(x)WP2O12 and Hf2WP2O12 exhibit large negative thermal expansion that is linear over a large temperature range up to at least 900° C., These new ceramic material particles may be mixed with polymers to make a composite suitable for use in backsheets for photovoltaic modules or in other applications. The thermal expansion coefficient of the composite can be tailored to match that of the solar cell in order to reduce stress resulting from daily thermal cycling.Type: GrantFiled: August 13, 2021Date of Patent: December 12, 2023Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Margaret Ellen Gordon, Clay Payne, Charles R. Bryan, Mark A. Rodriguez, Ashley Maes

Patent number: 11319779Abstract: A system and method for powering a borehole sensor with thermal energy is disclosed. The system includes a tubular pipe inserted into a subsurface borehole. A borehole casing is coaxially disposed with the tubular pipe. An annular space between the casing and the tubular pipe has a power source placed in the borehole to power a sensor in response to a temperature gradient between a surface of the casing and a surface of the tubular pipe. The method includes attaching thermopiles on the borehole casing or tubing; placing the thermopile in the annulus between the casing and the tubing; inducing a thermal gradient across the thermopile; generating an electrical energy in response to the temperature gradient; powering the sensor from the generated energy; and monitoring vertical expansion of a CO2 plume.Type: GrantFiled: June 26, 2020Date of Patent: May 3, 2022Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Charles R. Bryan, Jason E. Heath, Chowdary Ramesh Koripella, Thomas Dewers

Patent number: 10066471Abstract: A method of increasing recovery of liquid hydrocarbons from subsurface reservoirs, and particularly from those located in tight formations, is disclosed. One aspect includes calculating the in situ fractured formation wettability from real-time measurement of flowback volume and composition. Another aspect includes determining the composition of the fracturing fluid, the overflush or both, that will achieve higher liquid hydrocarbon recovery by increasing the water wettability of rock surfaces within the reservoir. Monitoring of rock-surface wettability through flowback volume and composition profiles allows the above mentioned injectates to be adjusted in the field to achieve maximal recovery. Other methods, apparatuses, and systems are disclosed.Type: GrantFiled: December 23, 2014Date of Patent: September 4, 2018Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Patrick V. Brady, Charles R. Bryan, Helmuth J. Heneman

Patent number: 9180428Abstract: Methods of capturing and immobilizing radioactive nuclei with metal fluorite-based inorganic materials are described. For example, a method of capturing and immobilizing radioactive nuclei includes flowing a gas stream through an exhaust apparatus. The exhaust apparatus includes a metal fluorite-based inorganic material. The gas stream includes a radioactive species. The radioactive species is removed from the gas stream by adsorbing the radioactive species to the metal fluorite-based inorganic material of the exhaust apparatus.Type: GrantFiled: March 4, 2015Date of Patent: November 10, 2015Assignee: Sandia CorporationInventors: Yifeng Wang, Andy Miller, Charles R. Bryan, Jessica Nicole Kruichak

Patent number: 9139364Abstract: A method for geo-sequestration of a carbon dioxide includes selection of a target water-laden geological formation with low-permeability interbeds, providing an injection well into the formation and injecting supercritical carbon dioxide (SC—CO2) into the injection well under conditions of temperature, pressure and density selected to cause the fluid to enter the formation and splinter and/or form immobilized ganglia within the formation. This process allows for the immobilization of the injected SC—CO2 for very long times. The dispersal of scCO2 into small ganglia is accomplished by alternating injection of SC—CO2 and water. The injection rate is required to be high enough to ensure the SC—CO2 at the advancing front to be broken into pieces and small enough for immobilization through viscous instability.Type: GrantFiled: July 25, 2013Date of Patent: September 22, 2015Assignee: Sandia CorporationInventors: Yifeng Wang, Charles R.

Patent number: 8753439Abstract: A process and apparatus for separating a gas mixture comprising providing a slot in a gas separation channel (conceptualized as a laterally elongated Clusius-Dickel column), having a length through which a net cross-flow of the gas mixture may be established; applying a higher temperature to one side of the channel and a lower temperature on an opposite side of the channel thereby causing thermal-diffusion and buoyant-convection flow to occur in the slot; and establishing a net cross-flow of a gas mixture comprising at least one higher density gas component and at least one lower density gas component along the length of the slot, wherein the cross-flow causes, in combination with the convection flow, a spiraling flow in the slot; and wherein the spiral flow causes an increasing amount of separation of the higher density gas from the lower density gas along the length of the channel. The process may use one or more slots and/or channels.Type: GrantFiled: August 23, 2013Date of Patent: June 17, 2014Assignee: Sandia CorporationInventors: Charles R. Bryan, John R. Torczynski, Patrick V. Brady, Michail Gallis, Carlton F. Brooks
