  • Barium titanate powder and manufacturing thereof
    Patent number: 11958755
    Abstract: Provided are a barium titanate powder having spherical shape fine particles which have an average particle diameter (D50) in a range of about 140-270 nm, a tetragonal structure having a markedly improved tetragonality (c/a) in a range of 1.007-1.01 in contrast to the conventional composition, and at the same time, a markedly improved crystallinity in a range of 93-96%, thereby showing improved dielectric properties, and a manufacturing method thereof.
    Type: Grant
    Filed: May 17, 2022
    Date of Patent: April 16, 2024
    Assignee: Korea Inst. of Ceramic Engineering & Technology
    Inventors: Moon Hee Choi, Hyeon Jin Jung, Seong Hyeok Choi

  • Dimer of chimeric recombinant binding domain-functional group fusion formed via disulfide-bond-bridge and the processes for producing the same
    Patent number: 7834258
    Abstract: The present invention relates to a method producing dimer of chimeric recombinant binding domain-heterogeneous functional group fusion([B-F fusion]2) by using covalent disulfide-bond-bridge connecting the two monomers of chimeric recombinant binding domain-heterogeneous functional group fusion(B-F fusion). The dimer of chimeric recombinant binding domain(B)-heterogeneous functional group(F) fusion was the first to be formed by using covalent disulfide-bond-bridge to connect monomers to have double binding valency of the monomer. It has higher functional efficiency to its targets and the production yield is high by containing said extension peptide chain.
