We investigate the shell structure of the 22Al (hyper)nucleus within the deformed Skyrme-Hartree-Fock approach, precisely reproducing the core binding energies by modifications to the nuclear force parameters. We analyze proton single-particle levels and density distributions and in particular the effect of adding a A hyperon in the deformed calculation. The latter might induce important core configuration changes, enhancing a possible proton halo feature.
Transition metal oxides (TMOs) are promising electrocatalysts for non-enzymatic glucose (NEG) sensors; nevertheless, their electrocatalytic performance is impeded by sluggish electron transfer kinetics and inadequate reactant adsorption. The rational design of the electronic and geometric structures of TMOs is crucial for enhancing their electrocatalytic activity toward glucose oxidation. Here, an Au-decorated hollow microspherical N-doped CuO heterojunction (Au/N-CuO-HM) was successfully prepared by a solvothermal method followed by calcination. Density functional theory (DFT) calculations and experimental results indicate that the formation of the Au/CuO heterojunction creates a built-in electric field at the interface, promoting electron transfer and reducing charge transfer resistance. More importantly, the incorporation of Au results in an upward shift of the d-band center (epsilon d) for the Cu sites, thereby strengthening the interaction between the electrocatalyst and glucose, as confirmed by the more negative adsorption energy of glucose after Au decoration (-2.351 vs. -1.856 eV). Simultaneously, the hierarchical hollow architecture of Au/N-CuO-HM enhances the accessibility of active sites and boosts mass transport, thereby leading to a high electrochemical active surface area of 0.286 cm2. Benefiting from the synergistic effect of both electronic structure modulation and hierarchical hollow architecture, the Au/N-CuO-HM modified electrode delivers outstanding electrocatalytic properties. This study not only provides insights into the roles of electron transfer regulation, epsilon d modulation, and hollow architecture design in electrocatalytic properties, but also offers an effective strategy for developing high-performance electrocatalysts for NEG sensors.
The COVID-19 pandemic and the ensuing control measures such as lockdown and isolation have led to widespread global disruptions, disproportionately impacting socioeconomically disadvantaged populations already at elevated risk of adverse mental health outcomes. This review aimed to synthesize the pooled prevalence of mental health problems among socioeconomically disadvantaged groups during the pandemic. A systematic search of English, Chinese, and preprint databases was conducted through August 2024. The analysis incorporated 47 studies, encompassing a total of 318,206 participants. The pooled prevalence of depressive symptoms, anxiety symptoms, and stress symptoms was 31
This study investigates how design qualities of Mixed Reality (MR) museums influence users’ continuance intention. Grounded in the Information System Success (ISS) model and perceived value theory, a conceptual framework is proposed and empirically validated using Partial Least Squares Structural Equation Modeling (PLS-SEM), addressing a specific gap in the literature. The research systematically examines how aesthetic quality, interaction quality, information quality, and narrative quality impact users’ continuance intention through the mediating roles of functional and emotional value. The findings indicate that interaction quality exerts a significant positive influence on continuance intention. Furthermore, functional and emotional value serve as essential mediators linking the various design qualities to users’ continued engagement. Specifically, aesthetic and narrative qualities influence continuance intention indirectly by enhancing emotional value, whereas information quality contributes to continuance intention by improving functional value. These insights offer theoretical contributions to the optimization of MR museum design and user experience management, highlighting the dual importance of functional and emotional engagement. Practically, the study provides actionable guidance for designing museums undergoing digital transformation and supports cultural institutions in leveraging MR technologies to achieve sustainable development.
A novel chalcone glycoside, named 4-hydroxy-6′′-(10′′,12′′-dimethoxy-11′′-hydroxybenzoyl)-6-O-β-D-glucopyranosyl-4′-rutinosylchalcone (1), together with six known chalcone glycosides (2–7) were obtained from Citrus medica L. var. sarcodactylis Swingle for the first time. Their structures were determined by analyzing spectral data and comparing with references. Among them, compounds 1, 3, and 5 exhibited important hepatoprotective activities at the concentration of 10 μM, with survival rates of 77.51 ± 1.05
