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.

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 ...

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.

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 ...

A team of employees from the Faculty of Chemistry and the Faculty of Materials Sciences of Lomonosov Moscow State University and colleagues have developed energy-efficient hydrogen detection sensors.

Catalytic converter converts the pollutant gases present in the engine exhaust into non pollutant gases through chemical reaction. Exhaust from engine is made to pass through a catalytic converter. It ...
