  • Protective internal coatings for porous substrates
    Patent number: 11945756
    Abstract: A material contains open pores in which the channels and pores that are internally coated with at least one layer of phosphorus-containing alumina. Such material is formed by infiltrating a porous material one or more times with a non-colloidal, low-viscosity liquid coating precursor, drying, and curing the coating precursor to form a phosphorus-containing alumina layer within pores of the material.
    Type: Grant
    Filed: October 19, 2020
    Date of Patent: April 2, 2024
    Assignee: APPLIED THIN FILMS, INC.
    Inventors: Sankar Sambasivan, Vikram S. Kaul, Francis R. Chapman

  • Transport of liquids and solute materials in nanochannels
    Patent number: 11059040
    Abstract: Transport of a vaporizable liquid containing at least one solute through a material containing nanochannels is performed by contacting material with at least one vaporizable liquid component and inducing liquid transport along nanochannel interior wall surfaces, wherein the material contains nanochannels having an average diameter up to about 300 nm, preferably up to about 100 nm, and liquid transport is induced by partial liquid vaporization. A film of solid material is deposited onto an interior nanochannel wall surface by removing the transport liquid.
