  • Patent number: 11971340
    Abstract: The present disclosure provides a method for predicting a lattice defect in a metal-organic framework (MOF) membrane. The method comprises acquiring a number n of a ligand during preparation of the MOF membrane, and acquiring a theoretical number m of connections formed between a core secondary building unit and a surrounding secondary building unit; setting a number of collisions of the ligand with the core secondary building unit and the surrounding secondary building unit; and calculating an expected value of a number of connections formed on lattices based on a collision probability, wherein the number of collisions is 1 or 2.

  • Publication number: 20230294070
    Abstract: The present disclosure relates to a mixed matrix carbon molecular sieve (CMS) membrane, a preparation method of the mixed matrix CMS membrane, and use of the mixed matrix CMS membrane in C2H4/C2H6 separation, and belongs to the technical field of membrane separation. The present disclosure solves the problem that the CMS materials in the prior art exhibit low selectivity and low flux during an ethylene/ethane separation process. In this patent, C3N4 is used as a filling particle to prepare a mixed matrix membrane (MMM), and the MMM is pyrolyzed to prepare a CMS membrane. The C3N4/6FDA-DAM MMM has prominent C2 separation performance.

  • Publication number: 20200057062
    Abstract: A use of an enhancer of rudimentary homolog (ERH) or a fragment thereof, in the preparation of a reagent for monitoring drug efficacy for rheumatoid arthritis, is provided. 35 proteins as candidate ACPA-negative RA autoantigens, 8 proteins as candidate autoantigens for predicting disease activity, and 6 proteins as candidate autoantigens for predicting treatment effect were screened by hybridizing high density protein chips with RA serum. Of the 6 proteins as candidate autoantigens for predicting treatment effect, one autoantigen, ERH, can successfully determine the effect of drug treatment on RA, and the AUC for predicting efficacy may be up to 0.733.

  • Publication number: 20190361019
    Abstract: A use of a pentaxin-related protein 3 (PTX3) or a fragment thereof, in the preparation of a reagent for diagnosing an anti-citrulline polypeptide antibody-negative rheumatoid arthritis disease, is provided. 35 proteins as candidate ACPA-negative RA autoantigens were screened by hybridizing high density protein chips with RA serum. 4 protein antigens were identified as having high sensitivity and specificity in the ACPA-negative serum of RA, and all were newly discovered autoantigens (DOHH, DUSP11, PTX3, and PAGE5). The invention indicates that DOHH, DUSP11, PTX3, and PAGE5 can be used as ACPA-negative RA diagnostic markers.

  • Patent number: 9475067
    Abstract: The present invention relates to a mineral processing technology and method for refractory chalcopyrite ores, particularly to a mineral processing technology and method for the separation of chalcopyrite from multiple natural types of copper ores containing chalcopyrite, pyrrhotite, talc and serpentine, which belongs to the technical field of mineral processing. It's characterized by: conducting a two-stage grinding on the chalcopyrite ore, with each grinding stage followed by size grading, and treating ores in different size fractions separately, wherein coarse-grain ores are separated in the presence of xanthate, with calcium oxide and CMC controlling the pH and acting as depressor respectively, while fine-grained ores are subjected to rougher in the presence of kerosene, and subsequently subjected to cleaner in the presence of xanthate.
