Metallic layered systems, consisting of alternating superconducting and ferromagnetic layers are studied by measurements of the electronical resistance, the magnetic susceptibility and the magneto-optical Kerr effect to investigate the interplay between superconductivity and magnetism.
Thin metallic "bridges" (width down to 40 nm) between two metallic layers can be prepared by nanostructuring methods. At low temperatures, the electronical transport exhibits interference effects due to the coherence of the conduction-electron wave functions. Normal and superconducting bridges are investigated.
Contacts consisting of a few or only one atom can be prepared by breaking and reconnecting nanostructural bridges (width = 100 nm). The current through single atoms is investigated by means of the superconducting proximity effect.

Los Alamos National Laboratory scientists have designed a new type of nanostructured-carbon-based catalyst that could pave the way for reliable, economical next-generation batteries and alkaline fuel cells, providing for practical use of wind- and solar-powered electricity, as well as enhanced hybrid electric vehicles.
In a paper appearing recently in Nature Communications, Los Alamos researchers Hoon T. Chung, Piotr Zelenay and Jong H. Won, the latter now at the Korea Basic Science Institute, describe a new type of nitrogen-doped carbon-nanotube catalyst
Depleted Uranium and our troops and all those

Oct. 2006: President George W. Bush signed the Department of Defense Authorization legislation. The House amendment was authored and introduced by Rep. Jim McDermott (D-Wa.) ordering a comprehensive study - with a report due in one year - on possible adverse health effects on U.S. soldiers from the U.S. military's use of DU - Depleted Uranium. The Senate companion bill was backed by Joe Lieberman of Conn., a democrat at the time. (McDermott's Web site: )
