TL;DR: T22 is a small molecule CXCR4 inhibitor that blocks T cell line–tropic HIV-1 entry into target cells and inhibits Ca2+ mobilization induced by pre–B cell growth stimulating factor (PBSF)/SDF-1 stimulation through CX CR4.
Journal ArticleDOI
High transport critical current density obtained for powder-in-tube-processed MgB2 tapes and wires using stainless steel and Cu–Ni tubes
TL;DR: In this paper, a powder-in-tube method was used to fabricate seven-core MgB2 wire with stainless steel and Cu-Ni tubes, and no heat treatment was applied.
Journal ArticleDOI
Microscopic role of carbon on MgB2 wire for critical current density comparable to NbTi
Jung Ho Kim,Sangjun Oh,Yoon-Uk Heo,Satoshi Hata,Hiroaki Kumakura,Akiyoshi Matsumoto,Masatoshi Mitsuhara,Seyong Choi,Yusuke Shimada,Minoru Maeda,Minoru Maeda,Judith L. MacManus-Driscoll,Shi Xue Dou +12 more
TL;DR: In this article, the role of carbon doping at the microscopic scale on magnesium diboride (MgB2) was investigated and it was shown that carbon encapsulates boron powder, prevents agglomeration and as a result reduces void fraction.
Journal ArticleDOI
Effect of SiO2 and SiC doping on the powder-in-tube processed MgB2 tapes
TL;DR: In this article, the effect of SiO2 and SiC nano-powder doping for powder-in-tube processed MgB2/Fe tapes was investigated, and only SiC doping was effective in enhancing critical current density (JC) values for MgH2 + B powder.
Journal ArticleDOI
Upper critical fields of powder-in-tube-processed MgB2/Fe tape conductors
TL;DR: In this paper, the authors measured the upper critical field of pure and SiC-added MgB2/Fe/Fe tapes prepared by the powder-in-tube process.
