  5. Superconductivity above 100 K in single-layer FeSe films on doped SrTiO3.

    Nature Materials 14(3):285 (2015) PMID 25419814

    Recent experiments on FeSe films grown on SrTiO3 (STO) suggest that interface effects can be used as a means to reach superconducting critical temperatures (Tc) of up to 80 K (ref. ). This is nearly ten times the Tc of bulk FeSe and higher than the record value of 56 K for known bulk Fe-based su...

    Granular materials subjected to blast loading caused by a central explosion exhibit a distinctive dual jetting phenomenon. A large number of fine particle jets are ejected from the outer edge of the charge upon the reflection of the shock wave from the free surface, and are soon overtaken and ov...
