The Alaska Local Section held a science cafe, Friday, November 12, 2010 at the local Barnes and Noble.  The topic of the event was The Mystery of High Temperature Superconductivity presented by Williaml Howard, professor of chemistry at the University of Alaska Fairbanks.  The event had 69 attendees and was advertised through posters distributed on campus of The University of Alaska, Fairbanks, to customers at Barnes and Noble and emails to university students and local section members.

 

An informal discussion of the synthesis and magnetic properties of YBa2Cu3O7, a high temperature superconductor, was given.  Furthermore, the Meissner Effect, which involves the levitation of a magnet over a cooled disc of YBa2Cu3O7, was demonstrated.

 

Thank you to the Alaska Local Section for providing the information for this blog post.
