Dr. Xuexi Zhang is a professor at Harbin Institute of Technology. He is the executive director of the Space Materials Science and Technology Branch of the Chinese Materials Research Society. His research interests include metal-matrix composites, composite interfaces, strengthening and toughening of aluminum-based composites, ferromagnetic-shaped memory alloys, solid-state cooling technology, and battery materials.

Guangping Zheng received his Ph.D. in materials science and engineering from Johns Hopkins University in 2002. He was a postdoctoral fellow at the Georgia Institute of Technology from 2002 to 2004. He is currently a professor at Hong Kong Polytechnic University. Dr. Zheng's research is in the areas of computational materials science, nanomechanics, and applications of nanomaterials in energy conversion and storage. In his capacity as principal investigator, he has secured 13 research grants from government agencies, including 6 RGC GRF, 4 ITF/GTF, and 3 Guangdong municipal research funds. Dr. Zheng has published over 230 papers in refereed scientific journals. He is a member of the editorial boards of several journals in his research fields.

Mingfang Qian is the deputy director of the Department of Materials Science, School of Materials Science and Engineering, Harbin Institute of Technology. She is a Class C high-level talent (leading talent) in Heilongjiang Province and an editorial board member of the international SCI journals "Magnetochemistry," "Frontiers in Materials," "International Journal of Metallurgy and Metal Physics," and a youth editorial board member of "Material Development and Application" and "Journal of Welding." She has successively presided over the National Natural Science Youth, the National Key R&D Program, the sub-projects of the National Ministry's Key Basic Research Project, the China Postdoctoral Special Funding, the Heilongjiang Province Postdoctoral Special Funding, the China Association for Science and Technology Youth Talent Support Project, the Heilongjiang Provincial Natural Science Foundation, the Harbin Institute of Technology Youth Outstanding Project, the Harbin Institute of Technology Research Star Project, etc. As a major participant, she participated in the National Key R&D Program, the Guangdong Provincial Key Field R&D Program, the Heilongjiang Provincial Fund Team Project, various projects of national ministries and commissions, and the third phase of the lunar exploration project. The lunar surface sampling robotic arm developed by the second finisher completed the Chang'e 5 lunar surface sampling mission in December 2020 and was successfully applied.
