  • Aqueous exfoliated graphene by amphiphilic cellulose nanofibrils for foldable and moisture-responsive nanopaper
    Patent number: 11920304
    Abstract: The present invention describes a method for preparing graphene by mixing graphite and carbon nanofibrils. The prepared graphene can be used to form nanopaper. The present invention also provides a method of preparing nanopaper by suspending cellulose nanofibrils and graphene, followed by vacuum filtering of the suspension.

  • Mesoporous ozonation catalyst, preparation method thereof, and application method thereof
    Patent number: 11458459
    Abstract: A mesoporous ozonation catalyst including a cerium-titanium-zirconium composite oxide. The catalyst is in the form of a solid spherical particle having a diameter of between 0.7 and 1.2 mm. The solid spherical particle exhibits lattice fringes under transmission electron microscope, and the lattice fringes have a spacing between 0.332 and 0.339 nm.

  • Analogs of sarcodictyin and eleutherobin
    Patent number: 5965718
    Abstract: Sarcodictyin A and B, eleutherobin, and bioactive analogs thereof synthesized using solid phase and solution phase chemistries. The synthetic method employs an attachment of common precursors, e.g., compounds 1880 or 200, on a solid support for generating conjugates 230 and 240, followed by standard chemical manipulations. A combinatorial library of sarcodictyins and eletherobin analogs was constructed with modified C-8 ester, C-15 ester and C-4 ketal functionalities and was screened for activity with respect to tubulin polymerization and cytotoxic activity against tumor cells, including Taxol-resistant lines. Compounds 600, 610, 630, 660-700, 730, 760, 850, and 920 were identified to be of equal or superior biological activities as compared to their corresponding natural product.
