In the article, James C. M. Li and colleagues point out that short platinum nanowires already have been used in sub-microscopic sensors and other applications. With platinum the primary material used in fuel cells (which generate electricity cleanly from hydrogen and oxygen), scientists have sought to produce long wires from this precious metal. Those wires could be woven into the first self-supporting webs of pure platinum for fuel cell electrodes.
By a process known as electrospinning, the team made platinum nanowires long enough to construct that web. "Our ultimate purpose is to make free-standing fuel cell catalysts from these nanowires. This technology is a key step toward better solutions," says Li. - AD

Affordable medical tests for the developing world
Chemical & Engineering News
A new generation of simple, affordable medical diagnostic tests is heading toward the developing world where they may protect impoverished people from AIDS, tuberculosis, malaria and other infectious diseases. That's the message from an article on these simple medical diagnostics scheduled for the March 16 issue of Chemical & Engineering News, ACS' weekly newsmagazine.
C&EN senior editor Celia Henry Arnaud explains that scientists have designed the tests for the harsh realities
