Abstract

We report the synthesis of ZnO nanostructures via electrodeposition onto films of polypyrrole (PPy) obtained by an electroless method from an aqueous suspension of PPy nanosheets. The PPy nanosheets are initially prepared in hexagonal oil-in-water (o/w) swollen liquid crystal (SLC) to provide the lamellar structure required to achieve further formation of a smooth electrode by an electroless process. The PPy particles can be easily extracted and transferred into an aqueous suspension that can be stored for months until its final use. The aqueous suspension of PPy is further spin-coated onto a glass or silicon substrate to form a flat thin film. These films exhibit a significant conductivity that allows further growth of various zinc oxide nanostructures by electrodeposition.

Catalyst Could Jump-Start E-Cars

June 4, 2013
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: )
Feb. 6, 2007: The New York newspaper, The Post Chronicle, reported that U

Nanotubes Increase Solar PV Conductivity 100 Million-Fold  — Sourceable
Carbon-based nanostructures are already being used as materials in solar cells with increasing frequency, yet their ability to enhance electrical performance has thus far been hampered by limited ability to assemble orderly networks using the materials.
