The authors would like to acknowledge the U.S. National Science Foundation (Grant DMR-2041050) for funding this work. M.D. thanks the Drexel UREP Undergraduate Research Grant and Murata Manufacturing, Japan, for their funding of her undergraduate research. P.P.M. was supported by the National Centre for Research and Development (NCBR) within LIDER XII LIDER/8/0055/L-12/20/NCBR/2021 project. Support for the electronic characterization (Y.Y. and S.J.M.) was provided by the U.S. Department of Energy (DOE), Office of Science, Office of Basic Energy Sciences, grant No. DE-SC0018618. R.A. acknowledges funding from the Spanish MICIU (PID2019-104739GB-100/AEI/10.13039/501100011033), CEX2023-001286-S MICIU/AEI/10.13039/501100011033) and by the MICIU with funding from European Union Next Generation EU (PRTR-C17.I1) promoted by the Government of Aragon (DGA) as well from the DGA project E13-23R. Part of the STEM imaging studies have been conducted in the Laboratorio de Microscopias Avanzadas (LMA) at Universidad de Zaragoza. The STEM work at Argonne National Laboratory (NJZ/RA) was supported by the Advanced Materials for Energy-Water Systems (AMEWS) Center, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Basic Energy Sciences at Argonne National Laboratory under contract DE-AC02-06CH11357 and at the University of Chicago the National Science Foundation MRI Award # 2117896. The Argonne Picoprobe AEM was developed under CRADA 1300701 between Argonne National Laboratory and Thermo Fisher Scientific Instruments. The authors would like to acknowledge Dr. Ray Unocic for his contribution to TEM characterization. M.D. would like to thank Aidan Cotton for his assistance in documentation. Finally, the authors would like to acknowledge the usage of the XRD instrumentation provided by the Drexel University Materials Characterization Core (MCC). This work has been adapted from the M.S. thesis titled "The Effect of n: A Delve into MXene Structure-Property Relations" by M.D. (Drexel University, 2024).
