  • Patent number: 10873090
    Abstract: A novel electrode current collector design that can improve performance and extend cycle life for rechargeable batteries based on metal electrodeposition is disclosed. The novel electrode current collector has a reduced effective surface area that can help to balance efficiencies between battery electrodes and to ensure non-uniform electrodeposition of metal onto the anode current collector during charge. One result is mitigation of internal short circuits that can cause a battery to fail prematurely.

  • Patent number: 10416082
    Abstract: Provided are methods, devices and systems that utilize free-surface fluidics and SERS for analyte detection with high sensitivity and specificity. The molecules can be airborne agents, including but not limited to explosives, narcotics, hazardous chemicals, or other chemical species. The free-surface fluidic architecture is created using an open microchannel, and exhibits a large surface to volume ratio. The free-surface fluidic interface can filter interferent molecules, while concentrating airborne analyte molecules. The microchannel flow enables controlled aggregation of SERS-active probe particles in the flow, thereby enhancing the detector's sensitivity.
