Prof. Mei Wang received her Ph.D. degree in Energy Science from Sungkyunkwan University, South Korea in 2014. After finishing the post-doctorate research at Sungkyunkwan University for 3 years, she joined the State Key Laboratory of Quantum Optics and Quantum Optics Devices, Institute of Laser Spectroscopy, Shanxi University, as a professor in 2017. Prof. Mei Wang has been engaged in precise control of material microstructures and the design of materials structures for applications for 14 years, including supercapacitors, electrochemical sensors, photocatalysis, strain/sensors, etc. Prof. Mei Wang has published more than 50 research papers and has been awarded expert contacted by the Shanxi Provincial Party Committee, and was recognized as a young outstanding talent in Shanxi Province, China.

NoProf. Xuyuan Chen is currently working at Institute of Laser Spectroscopy, Shanxi University, China. He received his Ph.D. in semiconductor materials and devices from the Eindhoven University of Technology, the Netherlands in 1997. After that he jointed Microelectronics Lab at School of Engineering Science, Simon Fraser University, Canada, where he worked on silicon microelectronic device and III-V DFB laser diodes. From 1997, he worked at the Physics Department at the University of Tromso, Norway, as an associate professor, and continued as a professor (2001) until 2002. During that time, his research topics were microelectronic devices and optoelectronics. Dr. Xuyuan Chen joined Microsystems and Nanotechnology, SINTEF ICT, Norway at end of 2002 where he started as a senior research scientist. In 2004, he was appointed as Professor of Department of Microsystems at the University of South-Eastern Norway (previous Vestfold University College). In 2023, he joined Shanxi University. He is currently working on advanced materials and micro-and nano-technoligy, as well as their applications in electrochemical energy storage systems, MEMs, and so on. He is author and co-author of more than 250 scientific publications in international journals and conferences, invited talks, and overview papers in the area of semiconductor technology, micro/nano-systems, and electrochemical technology.

Nabin Aryal is an Associate Professor at the Department of Process, Energy and Environmental Technology, Porsgrunn Campus, University of South-Eastern Norway (USN), Norway. He received MSc in Environmental Technology and Engineering from Ghent University, Belgium, with an Erasmus Mundus fellowship from the European Union and then a PhD. from the Technical University of Denmark (DTU) in Environmental Engineering with a fellowship from Novo Nordisk Foundation, Denmark. Before joining USN, Dr Aryal engaged in joint industrial postdoctoral research at Aarhus University and the Danish Gas Technology Center, Denmark. He has more than a decade of work experience from Norway, Denmark, Belgium, the Czech Republic, India, and Nepal. His current research focuses on bioelectrochemical systems, microbe-material interaction, biofilm-based bioprocess development, and anaerobic technology. He is an active Reviewer of more than 50 International Peer-Reviewed Journals, an editorial board member of the International Journal of Environmental Science and Technology - Springer, and lead editor of several special issues for international journals. He has co-authored over 50 scientific publications and edited two books on biogas upgrading and microbe-material interaction that received an h-index 18 (>1500 citations; Google Scholar).
