The release of toxic and harmful gases seriously endangers human health and social and
environmental safety. Sensitive determination of these gases is urgently needed to meet the …

Investigations into the mechanisms governing the behavior of metal oxide gas sensors
continue to be of great interest. Oxygen vacancies are a ubiquitous defect in this class of …

ZnO nanomaterials have attracted tremendous interest in the fields of photocatalysis,
sensors, solar cells, supercapacitors, etc. However, the performance of intrinsic ZnO is …

Currently, there are a huge number of environmental issues that the world is facing from past
few decades. However, the climate change is possibly the major environmental threat to …

To create an artificial structure to remarkably surpass the sensitivity, selectivity and speed of
the olfaction system of animals is still a daunting challenge. Herein, we propose a core …

In this report, we have prepared Cu-doped ZnO nanorods by a simplistic wet chemical
method with subsequent annealing. The phase formation, optical, surface morphological …

Ethanol vapor plays a significant role in the aspects of human health and industrial
production, thus necessitating a swift, sensitive, and low‐power ethanol detection in the field …

Despite being the most favorable ammonia (NH 3) gas sensors, metal oxide semiconductors
fail to deliver high selectivity and room temperature (RT) sensing. Tuning the metal oxide …

Metal–organic frameworks (MOFs) represent a versatile class of porous reticular materials
whose structures and properties can be precisely tailored for targeted applications. A …

In this work, four identical micro sensors on the same chip with noble metal decorated tin
oxide nanowires as gas sensing material were located at different distances from an …
