Two-dimensional (2D) Janus transition metal dichalcogenides MXY manifest novel physical properties owing to the breaking of out-of-plane mirror symmetry. Recently, the 2H phase of MoSH has been demonstrated to possess intrinsic superconductivity, whereas the 1T phase exhibits a charge density waves state. In this paper, we have systematically studied the stability and electron–phonon interaction characteristics of MoSLi. Our results have shown that both the 2H and 1T phases of MoSLi are stable, as indicated by the phonon spectrum and the ab initio molecular dynamics. However, the 1T phase exhibits an electron–phonon coupling constant that is twice as large as that of the 2H phase. In contrast to MoSH, the 1T phase of MoSLi exhibits intrinsic superconductivity. By employing the ab initio anisotropic Migdal-Eliashberg formalism, we have revealed the two-gap superconducting nature of 1T-MoSLi, with a transition temperature (Tc) of 14.8 K. The detailed analysis indicates that the superconductivity in 1T-MoSLi primarily originates from the interplay between the vibration of the phonon modes in the low-frequency region and the dz2 orbital. These findings provide a fresh perspective on superconductivity within Janus structures. [ABSTRACT FROM AUTHOR]

This article summarized the nursing care of a patient with head and neck squamous cell carcinoma (HNSCC) complicated with immune-related myositis. Nursing points included: nursing care on bilateral ptosis and dysphagia, the patient’s safety management and psychological nursing, health education on corticosteroids therapy, etc. Trough symptomatic treatment with integrated traditional Chinese and western medicine and individual nursing care, the patient’s condition was relieved, and the patient was discharged smoothly.

For improving the friction reduction and anti-wear properties of magnesium alloy surface,the evolution law of tribological performances of water-based lubricants with the different nano BN concentrations were evaluated using a reciprocating ball-on-plate tribometer for magnesium alloy/steel pairs.Results showed that the friction coefficient and wear loss of the samples decreased first and then increased with the increase of the content of nano BN in the lubricating fluid.When the mass fraction of nano BN in the lubricating fluid was 0.5%,the lubricating fluid exhibited the best tribological properties,and the friction coefficient and wear amount under this condition were reduced by 38.5%and 70%respectively,compared with those under the deionized water condition.The excellent friction reduction and anti-wear properties of nano-BN water-based lubricants were attributed to the deposition of nano BN on the surface of wear scars,which formed a protective film between the friction interfaces,thereby effectively avoided direct contact between friction pairs.

The extensive use of fossil energy leads to wanton emission of CO2 and serious environmental problems. The exploration of high‐performance catalysts plays a pivotal role in CO2 resource utilization. In this paper, CuCeyK catalysts are prepared by wet impregnation method using ordered mesoporous SiO2 as support for the reverse water gas shift (RWGS) reaction. The physicochemical properties of the prepared catalysts are characterized by H2‐TPR, BET, XRD, Quasi in‐situ XPS, H2‐TPD, and CO2‐TPD techniques. The results demonstrate thatthe Cu0 species can form synergistic effects with oxygen vacancies (Ov) to enhance the CuCeyK catalytic performance. Additionally, the electronic effects between Ce and Cu not only enhances the adsorption and activation performances of the catalyst towards CO2 and H2 molecules, but also effectively suppresses the sintering of Cu0 species, thereby enhancing the stability of the corresponding catalyst. It is worth mentioning that the Ce content also directly affects the catalytic performances of the CuCeyK catalyst. The CuCe15K catalyst with a Ce content of 15% displays excellent CO2 hydrogenation performances, and the CO2 conversion and CO selectivity up to 41 % and 100 % at 420 °C, respectively. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.
