  • Publication number: 20180207611
    Abstract: The present disclosure describes a particulate adsorbent material that includes: an adsorbent having microscopic pores with a diameter of <100 nm, macroscopic pores having a diameter of ?100 nm, and a ratio of a volume of the macroscopic pores to a volume of the microscopic pores greater than about 150%, wherein the particulate adsorbent material has a retentivity of about ?1.0 g/dL. A method of making the same includes: admixing an adsorbent with microscopic pores having a diameter <100 nm and a processing-aid that sublimates, vaporizes, chemically decomposes, solubilizes, or melts when heated to a temperature of ?100° C.; and heating the mixture to about 100-1200° C. for about 0.25-24 hours forming macroscopic pores having a diameter of ?100 nm when the processing-aid is sublimated, vaporized, chemically decomposed, solubilized, or melted, wherein a ratio of a volume of the macroscopic pores to a volume of the microscopic pores is >150%.

  • Patent number: 8987572
    Abstract: A system and method for teaching a user to discriminate and match musical pitch is disclosed. A pitch module generates a first melodic sequence for a user. The pitch module generates at least two symbolically depicted sequences including a first symbolic sequence that represents a pitch frequency that, when played, matches the first melodic sequence. A tracking module receives a selection of the first symbolic sequence and advances to a next level in response to receiving the selection of the first symbolic sequence.
