Sensor technology is one of the most important key technologies of the future with a
constantly increasing number of applications, both in the industrial and in the private sectors …

Based on the experimental results, obtained by studying both structural and gas-sensing
properties of the SnO2 and In2O3 films deposited by the spray pyrolysis method, we …

Wearable and portable devices with desirable flexibility, operational safety, and long
cruising time, are in urgent demand for applications in wireless communications …

It has long been known empirically that the electric resistance of a semiconductor gas
sensor under exposure to a target gas (partial pressure P) is proportional to Pn where n is a …

Semiconducting metal oxides are frequently used as gas‐sensing materials. Apart from
large surface‐to‐volume ratios, well‐defined and uniform pore structures are particularly …

An ordered mesoporous WO3 material with a highly crystalline framework was synthesized
by using amphiphilic poly (ethylene oxide)‐b‐polystyrene (PEO‐b‐PS) diblock copolymers …

Hierarchical assembly of hollow microstructures is of great scientific and practical value and
remains a great challenge. This paper presents a facile and one‐pot synthesis of Cu2O …

This contribution reports on the synthesis and the main physical properties of n-type SnO 2
nanoparticles synthesized for the first time by a completely green chemistry process using …

The adsorption of oxygen and its reaction with target gases are the basis of the gas
detection mechanism by using metal oxides. Here, we present a theoretical analysis of the …

This work examined the possibility of using SnO2 hollow spheres mediated by carbon
microspheres for the efficient detection of NO2 gas. The influences of gas concentration …
