  • Patent number: 10336896
    Abstract: A method of forming a hybrid physically and chemically cross-linked double-network hydrogel with highly recoverable and mechanical properties in a single-pot synthesis is provided. The method comprises the steps of combining the hydrogel precursor reactants into a single pot. The hydrogel precursor reactants include water; a polysaccharide; a methacrylate monomer; an ultraviolet initiator; and a chemical crosslinker. Next the hydrogel precursor reactants are heated to a temperature higher than the melting point of the polysaccharide and this temperature is retained until the polysaccharide is in a sol state. Then the single-pot is cooled to a temperature lower than the gelation point of the polysaccharide and this temperature is retained to form a first network. Thereafter, photo-initiated polymerization of the methacrylate monomer occurs via the ultraviolet initiator to form the second network.

  • Patent number: 10329849
    Abstract: The present invention relates to a multi-functional drilling experiment platform, which consists of a gantry, a hydraulic cylinder, a power swivel and a platform base. The gantry mainly realizes the control of the drill string during the drilling-in process. In order to simulate the vertical well, the inclined well, and the horizontal well, the drilling machine needs to rotate between 0° and 90°. The rotation of the gantry is realized by the extension and contraction of the hydraulic cylinder. The platform base is used to set up the gantry and the hydraulic cylinder, bearing the pulling, pressing and twisting loads of drilling experiments. Also, the platform base can move along the track to achieve different types of experiments. The multi-functional drilling experiment platform of the present invention realizes the load simulation experiment of the drilling machine at different angles using the gantry and the hydraulic cylinder.

  • Publication number: 20190184026
    Abstract: A linker peptide for constructing a fusion protein. The linker peptide comprises a flexible peptide and a rigid peptide. The flexible peptide consists of one or more flexible units. The rigid peptide consists of one or more rigid units. The flexible unit comprises two or more amino acid residues selected from Gly, Ser, Ala, and Thr. The rigid unit comprises a human chorionic gonadotropin ?-subunit carboxy-terminal peptide (CTP) bearing a plurality of glycosylation sites. The linker peptide can more effectively eliminate mutual steric hindrance of two fusion molecules, decreasing a reduction/loss of polymerization or activity resulting from improper folding of an active protein or a conformational change. On the other hand, the negatively charged, highly sialylated CTP can resist renal clearance, further prolonging a half-life of a fused molecule and enhancing bioavailability of a fused protein.
