The secret behind NIST's new gas detector? Chirp before sniffing

16-May-2011

Trace gas detection, the ability to detect a scant quantity of a particular molecule — a whiff of formaldehyde or a hint of acetone — in a vast sea of others, underlies many important applications, from medical tests to air pollution detectors to bomb sniffers. Now, a sensor recently developed at ...

Super sensitive gas detector goes down the nanotubes

15-Jan-2009

When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases. In a recent paper, researchers at the National Institute of Standards and Technology (NIST) described a new method for creating gas detectors so sensitive that some day they may ...
