Muhammad Ahsaan Bari obtained a bachelor's degree in physics from Bahauddin Zakariya University, Multan, and a master's degree in material physics from Government College University (GCU), Lahore, Pakistan. He commenced his research activities at the Solar Cell Applications Research Laboratory, Department of Physics, GCU Lahore. He later served as a Visiting Lecturer at the Department of Physics, University of Education, Multan Campus, Pakistan. He is currently pursuing a Ph.D. in materials engineering at the NanoBioMedical Center, Adam Mickiewicz University in Poznań, Poland. His current research focuses on the synthesis, characterization, and structure study of two-dimensional materials for multipurpose usage. In addition to publishing several research articles in international journals, Ahsaan has co-authored two international books published by IOP Publishing. His interdisciplinary background and active contributions to the field position him well to contribute to the advancement of materials research for energy and environmental applications  Dr. Zaka Ullah earned his Ph.D. from the University of Chinese Academy of Sciences, China, and is currently working as an Assistant Professor of Physics at the University of Education, Pakistan. He has authored around 90 research articles in high-impact international journals, including Advanced Energy Materials, Energy Storage Materials, Advanced Functional Materials, Nano Energy, Chemical Engineering Journal, Small, and Journal of Materials Chemistry A. Dr. Ullah holds one Chinese patent and has received a research grant from the Higher Education Commission (HEC) of Pakistan. He is an editorial board member of several journals, including Frontiers in Materials, and has reviewed over 1,000 manuscripts for more than 100 SCI-indexed journals. In recognition of his peer-review contributions, he received the Publons/Web of Science Top Peer Reviewer Award in 2019. He has been a complimentary member of the American Chemical Society (ACS) during 2019–2020 and 2022–2023. He is also a life member of the Pakistan Institute of Physics.
