A Balloon Just One Atom Thick
August 12, 2008
You hear a lot these days about carbon nanotubes. But lately there's been even more buzz about nanotubes' cousing, graphene -- a layer of graphite just one atom thick. It's
chemically stable and electrically conducting, two characteristics that make it (and carbon nanotubes) appealing for use in future electronics.
This week, researchers report an interesting use for graphene: an atomic membrane that is impermeable to gas molecules and can be easily incorporated into other devices.
The researchers from Cornell are calling their membrane the world's thinnest balloon and are saying that it could have a range of applications from hyper-sensitive pressure, light and chemical sensors
to filters able to produce ultrapure solutions. They report their work in the August 13 issue of ACS' Nano Letters.
