Delphi Corp., Troy, Mich., says it has developed the first automotive ammonia sensor. It should improve closed-loop control of selective catalytic-reduction (SCR) systems used in an increasing number ...

(Nanowerk Spotlight) Ammonia, a compound often associated with foul odors, is far more than an inconvenience – it’s a vital indicator of processes as diverse as food spoilage, environmental pollution, ...

Gaseous emissions from agriculture are a factor in global warming, with ammonia from manure storage and application being one significant contributor. Monitoring these emissions would be more readily ...

Aimed at municipal and industrial water, potable water and wastewater, these ammonium analytical sensors consist of two universal sensors and replaceable electrode cartridges. The S10 is an immersion ...

Ammonia is an alkaline compound that, when released into the air, is quickly adsorbed to surfaces and can travel anywhere ranging from a few hundred meters to hundreds of miles. NH 3 is also converted ...

Writing in the journal NanoResearch, a team at the University of Massachusetts Amherst reports this week that they have developed bioelectronic ammonia gas sensors that are among the most sensitive ...

Researchers have embedded new low-cost sensors that monitor breathing, heart rate, and ammonia into T-shirts and face masks. Imperial researchers have embedded new low-cost sensors that monitor ...

Ammonia is currently unregulated, and its emissions from agriculture and urban areas create unhealthy fine particulate matter, contributing to the formation of smog. The sensors, which are small, ...

Researchers at the University of Massachusetts (UMass) Amherst report that they have developed a novel bioelectronic ammonia gas sensor. The sensor uses electric-charge-conducting protein nanowires ...

Imperial researchers have embedded new low-cost sensors that monitor breathing, heart rate, and ammonia into t-shirts and face masks. Potential applications range from monitoring exercise, sleep, and ...

Researchers have designed a new type of microcapsule-embedded fluorescent molecule that can monitor the concentration of hydrogen ions and ammonia present in environmental and biological samples.
