The approach enables creation of material systems inaccessible by equilibrium and near‐equilibrium synthesis, and can be applied in novel practical applications as well as fundamental physics studies over a range of length‐ and energy scales. Ion implantation is a versatile, scalable, industry‐compatible tool, enabling the next step in this development. Here, we employ ion implantation to design and functionalize a mesoscopic magnetic architecture. We utilize a self‐supporting mask combined with implantation of 60 keV Fe ions to create an embedded array of approximately 8 µm wide circular ferromagnetic regions in a Pd film. The approach is contactless, free from surface residues and requires no focusing or scanning of the beam. Magnetic properties of the array are probed with longitudinal magneto‐optic Kerr effect measurement while varying sample temperature and applied magnetic field. Microstructures are visualized with Kerr microscopy and compared to the Fe distribution measured with microbeam proton induced X‐ray emission. Sample topography after implantation is obtained by atomic force microscopy, while ion beam analysis is employed to probe concentration depth profiles of implanted Fe, impurities and to investigate material mixing.This article is protected by copyright.

Currently, two‐dimensional (2D) carbon membranes are identified as deserving candidates since their high permeability and multiple tunable properties. However, they remain challenging to systematically uncover the potential relationships between structures and properties in various 2D carbon materials. For this, we trained a machine learning (ML) model based on feature datasets of 2D carbon materials effecting desalination properties. The results suggest that structures with a maximum pore size of 10‐12 atoms and atomic densities between 0.28 and 0.41 are more likely to achieve high properties. We selected the Cml‐MOR based on MOR type mordenite zeolite for validation. Further, Cml‐MOR is demonstrated to feature remarkable salt ion adsorption. The effective water flux of Cml‐MOR is 113.51 L·cm‐2·day‐1·MPa‐1, and the salt rejection at 110 MPa could reach to 98.9%. This work is expected to apply this efficient method to investigate the structure and properties of 2D carbon membranes with great structural diversity; this will attract more people to focus on them and explore their important potential for practical applications.This article is protected by copyright.
