A quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor has been developed for
the sensitive detection of ethylene (C_2H_4) at 10.5 µm using a continuous-wave distributed …

Optimizing materials and associated structures for detecting various environmental gas
pollutant concentrations has been a major challenge in environmental sensing technology …

Elucidating the capital mechanism for detecting greenhouse gases (GHGs) in the
atmosphere, based on sensitivity, performance, and cost‐effectiveness, is challenging, but …

The work is devoted to an overview of the current state of optoacoustic fiber-optic ultrasonic
transducers based on thermoelastic effect and fiber-optic interference receivers, its scope …

Long-term stability is an issue for semiconductor gas sensors, because the sensing material
normally needs to be exposed to ambient air (oxygen and water molecules). InAs nanowires …
