Improvement of superconductors within reach

Improvement of superconductors within reach: "'We have now made a theoretical modelling of the microscopic defects in these materials and simulated a superconducting current. We have managed to identify an accumulated electrical charge on the boundary between different misoriented crystal axes, as the main cause of the drastic drop in the electric current', explains physicist Brian M. Andersen, Niels Bohr Institute at the University of Copenhagen."
