  • Method for preparing an antimycin compound produced by sp.4-7
    Patent number: 11851692
    Abstract: Disclosed are an antimycin compound and a preparation method and use thereof. The preparation method comprises: fermenting a marine actinomycete (Streptomyces sp.4-7) with a preservation number CCTCCNO: M2020953 to obtain a fermented product and soaking and extracting the fermented product with ethyl acetate to obtain a crude extract; and carrying out separation and purification by normal-phase silica gel column chromatography, reversed-phase MPLC, and semi-preparative reversed-phase high-performance liquid chromatography. The invention has the advantages of resistance against Botrytis cinerea and Penicillium citrinum.
    Type: Grant

  • Process for fabricating an ultra-low-resistance superconducting joint having high shielding characteristics
    Patent number: 8745851
    Abstract: A process for fabricating an ultra-low-resistance superconducting joint that has high shielding characteristics. The process includes: corroding copper on the outer surface at the end of a NbTi/Cu superconducting wire to form terminal NbTi superconducting filaments; inserting same number of NbTi superconducting filaments into each through hole of the niobium layer of a Nb/NbTi/Cu multilayer composite rod; pressing at the outside of the Nb/NbTi/Cu multilayer composite rod to combine the Nb/NbTi/Cu multilayer composite rod and NbTi superconducting filaments together to form a joint; and inserting the joint into a YBCO tube, and then filling the YBCO tube with molten bismuth-lead-tin-cadmium (BiPbSnCd) alloy solder to form a superconducting joint with high shielding and low resistance characteristics.
