  • Patent number: 10906010
    Abstract: The present disclosure provides a method for producing a water permeable molecular sieve in which a porous substrate having micron-size pores has deposited on a surface thereof non-porous 2D platelets to seal, at the substrate surface, pores in the porous substrate to form a layer of 2D platelets. A curable sealing material is deposited onto the layer of 2D platelets and any remaining exposed areas of the surface of the porous substrate and curing the curable sealing material in order to form a sealed layer on the surface of the porous substrate to prevent water by-passing the non-porous 2D platelets and passing through the porous substrate. An array of sub-nanopores are then produced through the sealed layer with the array of sub-nanopores having a size to allow water to pass therethrough but not metal ions to give a water permeable molecular sieve characterized by water permeability at low di?erential pressures.

  • Patent number: 10538618
    Abstract: Disclosed herein are redox-active 6-oxoverdazyl polymers having structures (S1) and (S2) synthesized via ring-opening metathesis polymerization (ROMP) and their solution, bulk, and thin-film properties investigated. Detailed studies of the ROMP method employed confirmed that stable radical polymers with controlled molecular weights and narrow molecular weight distributions (Ð<1.2) were produced. Thermal gravimetric analysis of a representative example of the title polymers demonstrated stability up to 190° C., while differential scanning calorimetry studies revealed a glass transition temperature of 152° C. An ultrathin memristor device was produced using these polymers, namely a 10 nm homogeneous thin film of poly-[1,5-diisopropyl-3-(cis-5-norbornene-exo-2,3-dicarboxiimide)-6-oxoverdazyl] (P6OV), a poly-radical with three tunable charge states per each radical monomer: positive, neutral and negative.
