Nanobelts tackle nerve gases (Feb 8)
http://physicsweb.org/article/news/9/2/5
Researchers in the US have combined tin oxide "nanobelts" with low-power
microheaters to make sensors that can detect nerve agents. The devices
made by Li Shi and colleagues at the University of Texas at Austin and
the Georgia Institute of Technology are ultrastable, highly sensitive
and free from the "poisoning effect" that has previously limited the
widespread use of metal oxides as sensors (C Yu et al. 2005 Appl. Phys.
Lett. 86 063101).
