Why earthquakes stop
The barriers found on fault lines are usually regions in which a strong pinning force reduces the movement of the plates. However geologists cannot define the position of these barriers around the fau...
Tackling current limits in superconductors
Superconductors lose their unique properties above a critical current density of about 105 A cm-2. The best candidates for high-current applications – silver sheathed tapes of the bismuth-lead-s...
