Patent number: 11891313Abstract: Materials for binding per- and polyfluoroalkyl substances (PFAS) are disclosed. A fluidic device comprising the materials for detection and quantification of PFAS in a sample is disclosed. The fluidic device may be configured for multiplexed analyses. Also disclosed are methods for sorbing and remediating PFAS in a sample. The sample may be groundwater containing, or suspected of containing, one or more PFAS.Type: GrantFiled: May 7, 2020Date of Patent: February 6, 2024Assignees: Battelle Memorial Institute, New Jersey Institute of TechnologyInventors: Sayandev Chatterjee, Radha K.

Patent number: 11859863Abstract: Methods, systems and devices for managing humidity within an HVAC system including a nanostructured desiccant porous material configured to adsorb water from an inlet stream at a first air pressure and to release water from that material when subjected to a second air pressure when the second air pressure is lower than the first air pressure is located within a particular location so as to allow for the passage of wet air over the materials and allow adsorption of the water on to the material. When coupled with a vacuum pump water can be collected and released from the materials and the system, regenerating the material for future use and removing water from a stream at a significantly lower cost than existing processes.Type: GrantFiled: August 14, 2020Date of Patent: January 2, 2024Assignee: Battelle Memorial InstituteInventors: Bernard P. McGrail, Jeromy W. J. Jenks, Radha K. Motkuri

Patent number: 11764322Abstract: A beta-voltaic device made up of silica covered scintillating particles incorporated within an isotope absorbing layer to produce an improved power source. Lost beta particles are converted to UV light which is also converted to power in a beta-voltaic converter. The addition of the scintillating particles effectively increases the power efficiency of a BV device while maintaining the slim profile and smaller size of the power source. This arrangement makes possible implementation in space, defense, intelligence, medical implants, marine biology and other applications.Type: GrantFiled: March 19, 2021Date of Patent: September 19, 2023Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Lance R. Hubbard, Gary J. Sevigny, Radha K. Motkuri
