Publication number: 20240051871Abstract: Described herein are cementitious composite materials incorporating carbon nanostructures (e.g., nanotubes, nanoplatelets, nanoribbons) that are employed as amendments (i.e., admixtures or additives) to cementitious waste forms as a means to enhance radionuclide and hazardous waste (e.g., heavy metals, toxic organics) retention wherein the incorporation of well-dispersed carbon nanostructures yields more effective waste forms through the resulting modification of the cementitious composite nano-, micro-, and meso-structure (e.g., hindering the infiltration of oxygen and the leaching of waste), and the chemical interactions between chemically-affine waste molecules and the amended cementitious composite.Type: ApplicationFiled: June 8, 2023Publication date: February 15, 2024Applicants: University of South Carolina, Battelle Savannah River Alliance, LLCInventors: Fabio Matta, Mohammed Baalousha, Steven M.

Publication number: 20230017076Abstract: Methods and systems for the separation of hydrogen isotopes from one another are described. Methods include utilization of a hydrogen isotope selective separation membrane that includes a hydrogen isotope selective layer (e.g., graphene) and a hydrogen ion conductive supporting layer. An electronic driving force encourages passage of isotopes selectively across the membrane at an elevated separation temperature to enrich the product in a selected hydrogen isotope.Type: ApplicationFiled: July 29, 2022Publication date: January 19, 2023Inventors: DALE A. HITCHCOCK, STEVEN M. SERKIZ, TIMOTHY M. KRENTZ, JOSEF A. VELTEN, KYLE S. BRINKMAN, ERIC M. VOLGEL, KATHERINE T. YOUNG

Patent number: 11131628Abstract: Disclosed are spectroscopy systems and methods. A spectroscopy system can include a reference cell and a multi-pass sample cell. The reference arm can include an etalon and a reference cavity containing a reference gas. A system can include a fractional sublimation cold trap. Detectors of the reference and sample arms can detect both intensity and absorption spectra of impinging beams. A frequency calibration based on a reference absorption spectra can be used to analyze a sample absorption spectrum. The analysis can provide information regarding an absorption band shift of the sample absorption spectrum, said shift being related to the isotope concentration of the sample.Type: GrantFiled: May 12, 2020Date of Patent: September 28, 2021Assignee: Savannah River Nuclear Solutions, LLCInventors: Patrick E. O'Rourke, Kimberly Alicia Strange Fessler, Nicholas F. Deroller, Steven M. Serkiz

Patent number: 9220942Abstract: A magnetometer and magnet are incorporated into a glove in order to measure the magnetic field between the two carrying an athletic movement such as a golf swing. The resulting magnetic field can be related to the distance between the magnet and the magnetometer in the wrist-joint angle, allowing a real time receptacle signal to be transmitted to the user when a proper wrist angel in achieved.Type: GrantFiled: August 21, 2015Date of Patent: December 29, 2015Assignee: W.A.T.

Patent number: 9075148Abstract: Anodes for proportional radiation counters and a process of making the anodes is provided. The nano-sized anodes when present within an anode array provide: significantly higher detection efficiencies due to the inherently higher electric field, are amenable to miniaturization, have low power requirements, and exhibit a small electromagnetic field signal. The nano-sized anodes with the incorporation of neutron absorbing elements (e.g., 10B) allow the use of neutron detectors that do not use 3He.Type: GrantFiled: March 22, 2012Date of Patent: July 7, 2015Assignee: SAVANNAH RIVER NUCLEAR SOLUTIONS, LLCInventors: Joseph V. Cordaro, Steven M. Serkiz, Christopher S. McWhorter, Lindsay T. Sexton, Scott T. Retterer

Patent number: 6560920Abstract: A process of phytoremediation is provided in which the above-ground surface is first amended with stabilizing additives which will react with and bind subsurface contaminants. As the contaminants are brought to the surface through the growth of phytoextracting plants, the plants' vegetation is left to die in situ. As the plant biomass decomposes, the soil contaminants brought to the surface react with and/or are bound by the soil amendments. The soil amendments may further be provided in the form of a geotextile barrier or mat having one or more additive layers present within the mat structure.Type: GrantFiled: September 29, 2000Date of Patent: May 13, 2003Assignee: Westinghouse Savannah River Company, L.L.C.Inventors: Steven M.

Patent number: 5998490Abstract: A process and resulting product is provided in which a solid particulate, such as vulcanized crumb rubber, has the surface functional groups oxidized by ozonation using a nonpolar solvent. The ozonation process renders the treated crumb rubber more suitable for use in new rubber formulations. As a result, larger loading levels of the treated crumb rubber can be used in new rubber mixtures.Type: GrantFiled: May 8, 1997Date of Patent: December 7, 1999Assignee: Westinghouse Savannah River CompanyInventor: Steven M.
