  • Patent number: 12132176
    Abstract: Materials such as poly(vinylidene fluoride) (PVDF) and lithium cobalt (III) oxide (LCO) are recovered and recycled from cathode films isolated from end-of-life batteries, including lithium-ion batteries. Cathode films are immersed in solution including N,N-dimethylformamide (DMF), N-methyl-2-pyrrolidine (NMP), a tetrahydrofuran (THF):NMP mixture, or a THF:DMF mixture. The solution is able to dissolve PVDF, which can then be separated from LCO and a conductive substrate component of the cathode films via alumina column separation. A PVDF product can be precipitated and recovered, while the LCO and conductive substrate can be recovered directly from the alumina column separator. Both the PVDF and LCO are of suitable quality for use in new cathode films. Such recovery is shown to be achievable even at low solid to liquid ratio during the dissolution process.

  • Publication number: 20240351928
    Abstract: A fungal culture is provided that incorporates concentrations of Fenton reactants and white rot fungi biomass. These components synergize to degrade recalcitrant organic compounds such as lignins, perfluorochemicals including PFOA, plastics, and related compounds, particularly with 1.5 mM H2O2, 1 mM Fe2+, and Phanerochaete chrysosporium exhibiting lignin degrading capabilities comparable to cultures of Fenton-only reaction mediums with significantly higher concentrations of hydrogen peroxide. Both the fungi and the Fenton reactants work to degrade the organic compounds. Additionally, the Fenton reactants impose oxidative stress on fast-growing microbial competitors such as E. coli, selectively inhibiting the competing bacteria and their disadvantageous effects on white rot fungi activity. The white rot fungi recycle Fe(II) ions to reduce Fenton reactant input burden. An electro-Fenton reaction process can further reduce this burden by replenishing H2O2.

  • Publication number: 20240337825
    Abstract: A switchable light transmission module is disclosed that includes a substrate having a first surface defining at least part of an enclosed volume, a porous layer disposed on the first surface and in fluid communication with the enclosed volume, and a reservoir in fluid communication with the enclosed volume. The reservoir is configured to supply a fluid to the sealed volume such that the fluid contacts the porous layer. The fluid has a refractive index that is close to the refractive index of the porous layer, has a high wettability for the porous layer, and does not dissolve the porous layer. When in a dry state, voids in the porous layer are filled with air which has a much different refractive index than the porous layer itself, resulting in a surface that is reflective and not very transmissive.

  • Publication number: 20240325984
    Abstract: Cation exchange membranes are prepared via facile methods to control sulfonation of polystyrene repeat units. An amount of sulfuric acid is reacted with an acetic anhydride to form an amount of acetyl sulfate. The acetyl sulfate is then added to a known concentration of polystyrene units in boiling dichloromethane (DCM) to form sulfonated polystyrene random copolymers, including a random distribution of sulfonated polystyrene repeats and unsulfonated polystyrene repeats, with sulfonation levels between about 0.07 and about 0.225. The sulfonation level can be controlled by adjusting reaction times, reaction temperatures, and sulfuric acid loading in the reaction mediums. These membranes, neutralized via alkali metals, exhibit high charge densities and low hydration degrees, and maintain high permselectivity under various high solution concentrations.
