Researchers develop extremely sensitive hydrogen sensor

Hydrogen is a highly promising energy carrier. But it can also be dangerous, as it is combustible and difficult to detect. Using hydrogen safely requires sensors that can detect even the smallest of leaks. Researchers from ...

Super Sensitive Gas Detector Goes Down the Nanotubes

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 described a new ...

Breath or urine analysis may detect cancer, diabetes

(PhysOrg.com) -- A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing ...

Researchers engineer microscale optical accelerometer

Imagine navigating through a grocery store with your cell phone. As you turn down the bread aisle, ads and coupons for hot dog buns and English muffins pop up on your screen. The electronics industry would like to make such ...

Fast, easy way to make hydrogen nanosensors found by scientists

A team of Northern Illinois University scientists, with a major role played by NIU Ph.D. students, has discovered a new, convenient and inexpensive way to make high performance hydrogen sensors using palladium nanowires.

Ethylene sensor could help monitor plant health

To control flowering and fruit ripening, plants release the gaseous hormone ethylene. Environmental conditions, including drought, salinity and pathogens, can also cause levels of the hormone to fluctuate. Therefore, monitoring ...
