Metal sulfides have great potential for various applications. Numerous sulfur source molecules have been employed for metal sulfide synthesis, but there are still some problems, including hazardous byproducts and harsh experimental conditions. Discovering an environmentally friendly new sulfur source molecule is critical for metal sulfide synthesis. In this study, we introduce a new sulfur source molecule for metal sulfide synthesis, especially bismuth sulfide (Bi2S3). Using a new sulfur source molecule, 2-mercaptoethanol, in bismuth sulfide synthesis, high-aspect ratio and single-crystalline nanowires of bismuth sulfide have been synthesized in a low-temperature, solvothermal reaction process without a template.Cover Image ogy of bismuth sulfide can also be successfully tuned with the use of a biomolecule, glutathione, into tapered, cross- and T-shaped nanowires, as well as other interesting structures. We believe this new approach can be extended to the synthesis of other metal sulfide nanostructures and open new opportunities for device applications.

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.
