<title> Topic: Superconductors


<desc> Description:

Document cites a breakthrough in superconductivity research and
identifies at least one commercial application.


<narr> Narrative:

To be relevant, a document will cite a specific breakthrough in
superconductivity research, through development or use of new
materials, e.g., achieving superconductivity at a relatively higher
temperature (the goal being an economically practical level),
overcoming current-density limitation, ability to fabricate
superconductors in the shapes needed for practical applications; and
will identify at least one specific commercial application.  The
entity which achieved the breakthrough must also be identified.
