(1) MIT: New insights on fusion power

David Chandler, MIT News Office
December 3, 2008

Research carried out at MIT's Alcator C-Mod fusion reactor may have brought the promise of fusion as a future power source a bit closer to reality, though scientists caution that a practical fusion powerplant is still decades away.

(2)Disappearing superconductivity reappears -- in 2-D

Scientists studying a material that appeared to lose its ability to carry current with no resistance say new measurements reveal that the material is indeed a superconductor -- but only in two dimensions. Equally surprising, this new form of 2-D superconductivity emerges at a higher temperature than ordinary 3-D superconductivity in other compositions of the same material.

"The following structures are viewed (line, ball and stick, space filling and labeled) and measured (bond lengths, bond angles, dihedral angles) through a browser (including Internet Explorer or Netscape) using MDL Chime 2 or a version of RasMol . Both are available for free, and your browser can be configured to automatically use either when the files are selected. Many commercial packages can also be used to view the molecules that are stored as ascii files in the MDL “mol” data format. Chem 3D (from CambridgeSoft) is especially convenient because it can display all bond lengths or all bond angles with a single command.

The structures are generally arranged alphabetically by the central atom, and some abbreviations are used (Ph for phenyl, Bu for butyl, cp for cyclopentadienide, etc.).

Note that these are structures as reported in the literature and thus not idealized. The literature references and the method used to determine the structure for all structures are available as an Acrobat PDF file. The structures were extracted from The Cambridge Structural Database or taken directly from the literature. The placement and number of double bonds does not necessarily reflect the best Lewis structure, and in some cases double bonds are not shown at all"[1].
