Lighting the way to porous electronics and sensors

Many common household items and devices have a coating that improves performance. For example, the thin Teflon coating on cookware helps prevent food from sticking to the surface. However, it's difficult to prepare—at room ...

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 ...

Single-atom probe uses quantum information for the first time

Sensors collect certain parameters such as temperature and air pressure in their proximity. Physicists from Kaiserslautern and a colleague from Hanover have succeeded for the first time in using a single cesium atom as a ...

Hydrogen alarm for remote hydrogen leak detection

Hydrogen is considered as one of the promising alternative energy sources. Nevertheless, its application as an energy carrier is complicated due to its highly explosive nature when mixed with oxygen. These dangerous situations ...

Portable gas detection shrinks to new dimensions

A sensor for detecting toxic gases is now smaller, faster and more reliable. Its performance sets it up for integration in a highly sensitive portable system for detecting chemical weapons. Better miniature sensors can also ...
