Peishuo Wang is currently in his third year of undergraduate study at Hebei University of Technology (HBUT), College of Electronic and Information Engineering, majoring in Electronic Science and Technology, pursuing his Bachelor of Engineering degree. His main research interest is metal oxide semiconductor gas sensors. His research explores the mechanism of gas-sensitive performance enhancement through nanostructuring techniques such as modulation of material structure and morphology and heterostructure building, aiming to improve the monitoring capability of gas sensors in complex environments and their application value in the medical field. In addition, he combines his theoretical knowledge learned in his undergraduate studies with interdisciplinary practice to make new explorations in constructing gas-sensitive sensing materials.

Xueli Yang received her PhD degree in 2019 from College of Electronic Science and Engineering, Jilin University, China. Now she is a lecturer in School of Electronics and Information Engineering, Hebei University of Technology, China. Her current research interests mainly focus on the synthesis and characterization of semiconductor oxide functional materials and gas sensors.
