  • Patent number: 12292406
    Abstract: Devices for detecting an analyte in a sample suspected of containing the analyte, are provided. The devices include bio-functional, nanostructured, isoporous membranes (BNIM) integrated organic electrochemical transistor (OECT), herein BNIM-OECT, for the rapid and sensitive detection of the presence of an analyte of interest, in a sample, for example, a biological sample. The membrane (i.e., BNIM) is physically separated from the OECT channel therefore the electronic device can be used multiple times. The isoporous membrane is functionalized to include a binding partner for the analyte being detected. The BNIM-OECT can be used for disease detection, by functionalizing the BNIM-OECT with a binding partner to an analyte associated with the disease, applying a collected biological sample to the BNIM-OECT. A decrease in channel current as a result of analyte binding to its binding partner on the isoporous membrane indicates the presence of the analyte in the sample.

  • Patent number: 12257551
    Abstract: A bipolar electrodialysis (BPED) cell is able to bipolar convert salt solutions into acid and base solutions. However, protons migrate through the anion exchange membranes and tend to neutralize the base solution. In a bipolar electrodialysis system described herein, multiple BPED cells are arranged to provide a multi-stage treatment system. Up to half, or up to one third, of the stages have cells with acid block anion membranes. The one or more stages with acid block anion membranes are located at the acid product output end of the system, where the acid concentration in the system is the highest. Replacing the traditional anion membranes in some of the stages with acid block anion membranes allows higher concentration products to be produced with moderate increase in energy consumption.

  • Patent number: 12251692
    Abstract: The design of bifunctional catalysts for water splitting by modifying the electronic structure of the catalyst. That bifunctional catalyst that is synthesized is a quaternary FeNi—PSe nanoporous film (FeNi—PSe NF). A self-supported FeNi—PSE NF is synthesized and used as an anode and a cathode in a two-electrode electrolytic cell. The cell is subjected to a water source, and the FeNi—PSe NFs split the water molecules to produce hydrogen fuel. The slightly oxidized FeNi—PSe surface serves as an active site for oxygen evolution reactions, making hydrogen evolution reactions and oxygen evolution reactions well-balanced, thereby improving electrolysis efficiency.
