A simple grinding-calcination approach to prepare the Co3O4–In2O3 heterojunction structure with high-performance gas-sensing property toward ethanol

The development of gas sensing devices with high sensitivity, good selectivity and excellent stability is becoming increasingly important since toxic or harmful gases are a threat to human health.

A low temperature operating gas sensor with high response to NO2 based on ordered mesoporous Ni-doped In2O3

This study demonstrated that doping Ni enhanced the response of the sensor based on mesoporous In₂O₃ to NO₂.

Si doped highly crystalline mesoporous In2O3 nanowires: synthesis, characterization and ultra-high response to NOx at room temperature

The synthesized INW-2 has an ultrathin surface layer and high density defects. The special structure offers available active centers for gas/surface reactions. INW-2 sensor possesses the ultrahigh response and selectivity to NOx at room temperature.

Effects of microstructures on the compression behavior and phase transition routine of In2O3 nanocubes under high pressures

In addition to size and morphology, the microstructure may play an important role and induce differences in the compression and phase transition behaviors of nanomaterials under high pressures.

Bio-green synthesis of Ni-doped tin oxide nanoparticles and its influence on gas sensing properties

Using a novel, cost-effective and environmentally friendly biosynthesis method, Ni-doped SnO₂ nanoparticles have been synthesized. Gas sensing results suggest that the Ni-dopant is a promising additive to fabricate low cost SnO₂ based sensors.
