Critical current density Jc versus magnetic field H curves for bulk MgB2.

Caption

Scientists at SIT in Japan produced high-performance MgB2 by ultrasonicating boron (B) in 2-propanol for varying durations. The inset displays high magnification FE-SEM images of B particles obtained after 0 and 45 minutes, respectively, with the latter showing 20-50 nm refined grains.
