Two-dimensional (2D) materials offer many key advantages to innovative applications, such as spintronics and quantum information processing. Theoretical computations have accelerated 2D materials design. In this issue of ACS Nano, Kumar et al. report that ferromagnetism can be achieved in functionalized nitride MXene based on first-principles calculations. Their computational results shed light on a potentially vast group of materials for the realization of 2D magnets. In this Perspective, we briefly summarize the promising properties of 2D materials and the role theory has played in predicting these properties. In addition, we discuss challenges and opportunities to boost the power of computation for the prediction of the "structure-property-process (synthesizability)" relationship of 2D materials.

Single-crystal Au(111), renowned for its chemically inert surface, long-range "herringbone" reconstruction, and high electrical conductivity, has long served as an exemplary template in diverse fields, , crystal epitaxy, electronics, and electrocatalysis. However, commercial Au(111) products are high-priced and limited to centimeter sizes, largely restricting their broad applications. Herein, a low-cost, high-reproducible method is developed to produce 4 in.

Covalent-organic frameworks (COFs) are useful architectures for two- (2D) and three-dimensional (3D) active materials. Recently, the characterization of the nonplanar benzo[5,6][1,4]dithiino[2,3-]thianthrene-6,13-dicarbonitrile (bTEpCN), as a prototypical section of 2D COFs, enables further understanding of the properties on such extended networks. Upon adsorption on the Au(111) surface, planarization of bTEpCN is achieved.

High-quality two-dimensional transition metal dichalcogenides (2D TMDs), such as molybdenum disulfide (MoS), have significant potential for advanced electrical and optoelectronic applications. This study introduces a novel approach to control the localized growth of MoS through the selective oxidation of bulk molybdenum patterns using Joule heating, followed by sulfurization. By passing an electric current through molybdenum patterns under ambient conditions, localized heating induced the formation of a molybdenum oxide layer, primarily MoO and MoO, depending on the applied power and heating duration.

We present a versatile method for synthesizing high-quality molybdenum disulfide (MoS) crystals on graphite foil edges via chemical vapor deposition (CVD). This results in MoS/graphene heterostructures with precise epitaxial layers and no rotational misalignment, eliminating the need for transfer processes and reducing contamination. Utilizing in situ transmission electron microscopy (TEM) equipped with a nano-manipulator and tungsten probe, we mechanically induce the folding, wrinkling, and tearing of freestanding MoS crystals, enabling the real-time observation of structural changes at high temporal and spatial resolutions.
