A new gas sensor using ruthenium dioxide nanosheets achieves ultra-sensitive ethanol detection down to 5 ppb, enabling real-time breath alcohol monitoring at under 30 milliwatts.

image: The combination of a commercial iron-complex catalyst (ferrocene) and well-adjusted unconventional reaction conditions led to a highly selective, fast and reusable catalytic system for the mild ...

The catalytic bead lower explosive limit (CB LEL) sensor is widely used for combustible gas detection based on its low cost, ease of use, and the ability to detect a wide range of gases. However, for ...

Reducing pollutant emission of vehicles and meeting stricter exhaust gas standards are major challenges when developing catalytic converters. A new concept might help to efficiently treat exhaust ...

Whether they are used to detect methane gas in mines, carbon monoxide in homes, or combustibles in nuclear plants, gas detectors are now an integral part of home, commercial, and industrial safety.
