The exploration of acetone gas sensors with excellent selectivity and high sensitivity is a critical challenge. The realization of specific adsorption of target gas by gas-sensitive materials and the ...

This 320x480 3.5-inch IPS display may not seem like much of an upgrade on the surface over the ESP32 CYD that I've been ...

In this work, we present a setup for measuring substances separated by gas chromatography (GC) simultaneously with a mass spectrometer (MS) and a metal oxide semiconductor (MOS) gas sensor. The sensor ...

The gas sensor, based on a p–n heterojunction structure, was fabricated by vertically stacking a nanometer-thick layer of p-type cobalt phthalocyanine (CoPc) on a solution-processed n-type ...

Presently, numerous state-of-the-art approaches are being adapted for gas sensing and monitoring. These include hazardous gas leak detection as well as ambient air monitoring. Photoionization ...
