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.

This study aims to assess the global prevalence of kinesiophobia and the potential influencing factors among patients with heart disease. A comprehensive search was conducted in PubMed, Embase, Web of Science, PsycINFO, and Scopus databases to identify studies reporting on the prevalence of kinesiophobia and its influencing factors in heart disease patients up to January 2024. A random-effects model was employed to aggregate prevalence rates. Heterogeneity sources were investigated through subgroup analysis, while differences in the prevalence of kinesiophobia across regions, types of heart disease, and gender were evaluated. Additionally, a qualitative analysis of the factors influencing kinesiophobia was performed. This research incorporated 15 studies from six countries, with 14 providing data on the prevalence of kinesiophobia and nine exploring its potential influencing factors. The findings indicated that the overall prevalence of kinesiophobia among heart disease patients was 61.0% (95% CI 49.4–72.6%). Subgroup analysis revealed that the prevalence in upper-middle-income countries was 71.8% (95% CI 66.2–77.4%), while it stands at 49.9% (95% CI 30.2–69.5%) in high-income countries. The prevalence rates among patients with coronary artery disease, heart failure, and atrial fibrillation were 63.2% (95% CI 45.2–81.3%), 69.2% (95% CI 57.6–80.8%), and 71.6% (95% CI 67.1–76.1%), respectively. Gender-wise, no significant difference was observed in the prevalence of kinesiophobia between men and women (52.2% vs. 51.8%). A total of 24 potential influencing factors of kinesiophobia were identified, with education level, monthly income, anxiety, and exercise self-efficacy being the most recognized. The prevalence of kinesiophobia in patients with heart disease is notably high and is influenced by a multitude of factors. Early implementation of targeted preventive measures is imperative to mitigate the incidence of kinesiophobia in this population. [ABSTRACT FROM AUTHOR]

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.

Waste Zanthoxylum bungeanum branches were used to prepare activated carbon adsorbents with high mesopore ratio by H3PO4 staged activation method with adding KNO3 additive. The prepared activated carbon adsorbents were characterized by SEM, BET, FT-IR, and XRD. The adsorption properties of the prepared activated carbon adsorbents were evaluated by the toluene adsorption/desorption in air. The quasi-first-order, quasi-second-order, and Bangham models were used to fit the obtained toluene adsorption results. The oxidative etching of KNO3 additive improved the pore-forming ability of the H3PO4 activator to enhance the activation pore-forming effects of the selected biomass raw material. The secondary pore-forming effects of K atoms promoted the effective expansion of the pore diameter in the activated carbon preparation process to prepare activated carbon adsorbents with high mesopore proportion. The specific surface area and mesopore proportion of the activated carbon adsorbents prepared by adding KNO3 additive exceeded 1100 m2/g and 71.00%, respectively, and the toluene adsorption capacity exceeded 370.00 mg/g. The rich mesopore structures can effectively reduce the toluene mass transfer resistance, which can promote the corresponding activated carbon adsorbent to be regenerated by low-temperature (40 °C) thermal desorption. The toluene adsorption on the prepared activated carbon adsorbents includes surface adsorption and diffusion in pore structures, and the toluene adsorption mechanism is more consistent with the Bangham kinetic model.

The CeO2 and CeCoO composite oxide catalysts with bimodal mesopore structures were prepared by hard-template method and used for ethanol complete oxidation in air. The physicochemicalphysicochemical properties of the prepared catalysts were characterized by XRD, BET, TEM, XPS, H2-TPR, and O2-TPD. The Co species can be dissolved into CeO2 lattice to form Ce–O–Co solid solution, which promotes reactive oxygen species to be formed on the prepared CeCoO oxide catalysts surface. The bimodal mesopore structures can be obtained by the used hard-template method, and the pore structures of the prepared CeCoO oxide catalysts can be affected by the introduction of Co species. The synergistic effects from bimodal mesopore structures and reactive oxygen species can effectively boost ethanol complete oxidation to final product CO2. The CeCo2 catalyst with Ce/Co mole ratio of 2.0 exhibites superior ethanol complete oxidation activity and service stability, the ethanol oxidation conversion and final oxidation product CO2 selectivity reached 99.8 % and 99.2 % at 200 °C, respectively. This work indicates that the bimodal mesoporous CeCoO solid solution composite oxide catalyst is a promising candidate for OVOCs oxidation elimination from air. [ABSTRACT FROM AUTHOR]
