Summary: This study investigated the adsorption of carbon monoxide (CO) on non-metallic edge-modified zigzag arsenene nanoribbon (ZAsNR) by using a density generalized theory first principles approach. The results showed that CO molecules preferred to be valley-positioned and tilted when adsorbed on the ZAsNR surface. Furthermore, the different modifications of H, B, C, N, and F atoms on ZAsNR led to varying levels of adsorption energy and conductivity variation. It was found that the O-atom-modified ZAsNR system exhibited significant charge transfer and increased conductivity, indicating its potential as a new sensor material.

Summary: The edge elasticity and its effect on flexoelectric response of Janus MoSSe nanoribbons were systematically explored using density functional theory calculations. Both armchair and zigzag terminated edges of the nanoribbons were found to be under tension due to edge stresses, leading to spontaneous bending deformation. The flexoelectronic properties of the semiconducting armchair MoSSe nanoribbons strongly depend on their widths, with the out-of-plane flexoelectric coefficients varying accordingly.

Summary: The recent isolation of two-dimensional magnets has opened up exciting possibilities for spintronics and magnonics in miniaturization. Atomically thin materials have outstanding deformation capacity, which allows their properties to be controlled through strain engineering. In this study, the magnetic properties, magnon dispersion, and spin dynamics of the air-stable 2D magnetic semiconductor CrSBr under mechanical strain were investigated using first-principles calculations. The results provide a detailed analysis of the competing interactions that stabilize the long-range ferromagnetic order in the monolayer. It is shown that the magnon dynamics of CrSBr can be selectively modified along different crystallographic directions by applied strain, indicating the potential of this quasi-1D electronic system for magnon straintronics applications. Additionally, a 30% increase in TC, which allows spin waves to propagate at higher temperatures, is predicted to be driven by strain.

Summary: In this study, a Janus structure, ASSiN2 (A = Cr, Mo, W) monolayers, was proposed as a potential high-performance photocatalyst with stable structure and semiconductor behaviors. The Janus structures were found to have enhanced intrinsic electric field, facilitating the separation of photogenerated carriers. Specifically, the WSSiN2 monolayer exhibited suitable band-edge potentials for photocatalytic water splitting, high electron mobility, and strong visible-light absorption ability, suggesting its great application potential in photocatalysis. These findings provide reliable evidence for the further development of 2D Janus materials as high-performance photocatalysts.

Summary: MXenes, a newly discovered class of two-dimensional materials, show promising potential for biomedical and electronic applications. First-principles calculations on the titanium carbide MXene surface reveal physisorption as the dominant mechanism for nucleobases, with molecules sitting parallel to the surface at a distance of about 2.5A. The moderate adsorption energies and van der Waals interactions suggest the Ti2CO2 MXene's suitability as a nucleobase sensor.

Summary: This study investigates the adsorption mechanisms of hydrogen atoms and molecules on 2D metallic porphyrins using DFT simulations. The results show that hydrogen atoms are chemisorbed while hydrogen molecules are physisorbed. Vanadium and chromium embedded porphyrins exhibit the highest maximum adsorption energies for hydrogen atoms, while scandium embedded porphyrins exhibit the highest maximum adsorption energy for hydrogen molecules. Furthermore, charge transfer is minimal for physisorption and significant for chemisorption. Uniaxial strain has minimal effects on the adsorption properties of 2D metallic porphyrins.

Summary: Beyond traditional heteroepitaxy, 2D-materials-assisted epitaxy opens opportunities to revolutionize future material integration methods. However, basic principles in 2D-material-assisted nitrides' epitaxy remain unclear, which impedes understanding the essence, thus hindering its progress. Here, the crystallographic information of nitrides/2D material interface is theoretically established, which is further confirmed experimentally. It is found that the atomic interaction at the nitrides/2D material interface is related to the nature of underlying substrates. For single-crystalline substrates, the heterointerface behaves like a covalent one and the epilayer inherits the substrate's lattice. Meanwhile, for amorphous substrates, the heterointerface tends to be a van der Waals one and strongly relies on the properties of 2D materials. Therefore, modulated by graphene, the nitrides' epilayer is polycrystalline. In contrast, single-crystalline GaN films are successfully achieved on WS2. These results provide a suitable growth-front construction strategy for high-quality 2D-material-assisted nitrides' epitaxy. It also opens a pathway toward various semiconductors heterointegration.

Summary: The mechanical, electronic, and magnetic properties, structural transformation, and stability of CdSe nanoribbons (CdSeNRs) under uniaxial tensile strain have been studied using first-principles calculations. The band gap decreases with increasing tensile strain in the elastic range, but dramatically increases when the strain exceeds the yielding point for armchair CdSeNRs (ACdSeNRs). The magnetic moment of zigzag CdSeNRs (ZCdSeNRs) changes slightly in the elastic range and decreases with increasing strain in the plastic range due to structural transformation. The mechanical properties, such as force constant and in-plane stiffness, are dependent on the width of the nanoribbons for both ACdSeNRs and ZCdSeNRs. The binding energies indicate that armchair nanoribbons are more stable than zigzag nanoribbons of comparable width. The electronic and magnetic properties of CdSeNRs can be effectively modulated by applying tensile strain, while the mechanical properties are highly dependent on strain and width.

Summary: The addition of alloying elements has a significant impact on the behavior of helium (He) in metal alloys. Based on first-principles calculations, the effects of solutes on the behavior of He and He-He pairs in face-centered cubic (fcc) iron were investigated. It was found that Ti, P, Si, and C have a stronger attraction to He compared to Ni and Cr in fcc iron. Ti and P can weaken He self-trapping, while Cr and C are beneficial for He self-trapping. Ti and Si increase the diffusion barrier of He, while Cr and P decrease it.
