Designer labels have a lot of cachet -- a principle that’s equally true in fashion and physics. The future of nuclear physics is in designer isotopes -- the relatively new power scientists have to make specific rare isotopes ... | |
 A 'squeeze' in cuprates may explain superconducting temperatures May 07, 2008 | User rating: 4.6 / 5 after 31 vote(s)
| User comments: 2
New experiments at Cornell have verified a theory that variations in the distance between atoms in cuprate superconductors account for differences in the temperature at which the material begins to superconduct. ... | |
