We fabricated several sapphire screw threads and performed a strength test on them at the liquid nitrogen temperature of 77 K. The screw threads were subjected to and withstood a 3000 N load. To the best of our knowledge, this is the first strength test of sapphire screw threads at a cryogenic temperature. The result suggests a new way of connecting(More)
An extractive liquid-surface immobilization (Ext-LSI) system, which consists of a hydrophobic organic solvent (an upper phase), a fungal cell-ballooned microsphere layer (a middle phase) and a liquid medium (a lower phase), is a unique interfacial cultivation system for fungi. The fungal cells growing at the interface between the organic and aqueous phases(More)
