Caption This paper reviews the structure and principle of semiconductor-based gas sensors, the synthesis methods of single atom catalysts, the mechanisms by which single atom catalysts enhance gas ...

However, a critical challenge for their practical application is the limited lifetime of organic semiconductors, which are vulnerable to degradation caused by moisture and oxygen. This leads to a ...

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen ...
