Artificial olfaction based on gas sensor arrays aims to substitute for, support, and surpass
human olfaction. Like mammalian olfaction, a larger number of sensors and more signal …

In the realm of gas sensors, research has been rather comprehensive on the gas-sensitive
features of ordinary binary metal oxide materials. At present, ternary metal oxide materials …

Nanostructured La-based perovskite oxides− LaMO 3 (M= Al, Co, Fe) were synthesized by a
new co-precipitation procedure using metal nitrate and carbonate salts as starting materials …

In this study, an investigation about the oxygen sensing properties of lanthanum orthoferrite
(LaFeO 3) ceramics is reported. LaFeO 3 nanoparticles were synthesized by using tartaric …

Currently, SmFeO3-based sensors are an effective platform for detecting acetone gas.
However, they require high operating temperatures, which increases energy consumption …

Conventional solid-state reaction process was adopted to prepare PrFe 0.5 Cr 0. 5 O 3
polycrystalline material. High-temperature X-ray diffraction (XRD) patterns confirmed the …

Abstract Uniform Ba-doped LaFeO 3 nanofibers (NFs) with pure orthorhombic perovskite
phase were successfully fabricated by electrospinning and subsequent calcination, and their …

The contributions of Italian researchers to sensor research in 2015 is reviewed. The analysis
of the activities in one year allows one to obtain a snapshot of the Italian scenario capturing …

As a typical p-type semiconductor gas-sensing material, LaFeO3 has good response
stability to H2S, but its responsiveness is low, and the detection limit is not low enough for …

The H2S concentration in exhaled breath increases marginally with the progress of
periodontal disease, and H2S is considered to be one of the most important gases related to …
