3-octanone has been widely identified as a primary biomarker for mold and insect infestation in wheat. Nevertheless, to date, no chemiresistive sensor based on a metal oxide semiconductor with excellent sensing properties for 3-octanone has been developed. In light of the extensively reported superior efficacy of CoO-based sensors for ketone detection, we designed CoO samples with various hierarchical morphologies (hollow sphere, multi-wall sphere, flower-like, and urchin-like), which were determined by regulating solvent and organic ligand.

In thermal spray process, the characteristics of in-flight particles (velocity and temperature) play an important role regarding the microstructure of the deposit and thus the coating performances. The implementation of diagnostic devices is necessary to measure such characteristics. Many imaging systems and algorithms have been developed for identifying and tracking in-flight particles.
