In this study, SnO₂/SnS₂ heterojunctions were successfully constructed in situ via a low-temperature solid-phase method using synthesized tin oxide hydroxide sulfate precursors and thiourea as raw materials. During heating, the precursors progressively transformed into SnS₂/SnO₂ heterojunctions while retaining their agglomerated structure. The regulatory role of NH₄Cl additive in product phase formation was systematically investigated. Furthermore, the structure-property relationship between microstructure, optical characteristics, and photocatalytic performance of the composite was elucidated. Phase and microstructure characterization (XRD, SEM, TEM, XPS, Raman) confirmed that introducing NH₄Cl promoted the close integration of SnO₂ and SnS₂ phases and heterojunction formation through a chemical vapor transport mechanism. The composite exhibited a hierarchical nanostructure, suitable mesoporous characteristics, and significant interfacial electron interaction. UV-Vis absorption spectroscopy and photoluminescence analysis indicated that the heterojunction effectively broadened the light response range and facilitated the separation of photogenerated carriers. Photocatalytic degradation experiments of MO demonstrated that the as-prepared SnS₂/SnO₂ composites exhibited good performance under both UV and visible light. The optimized composite (S2) achieved complete degradation of MO within 6min under UV light and within 20min under visible light. Free-radical trapping experiments confirmed that superoxide radicals (•O₂⁻) and hydroxyl radicals played dominant roles in the photocatalytic process.

The aging and disability of China’s rural population have a huge impact on the long-term care system, and the intrinsic capacity and healthy aging of the disabled older adults in rural areas need to be improved urgently. To investigate the current status of intrinsic capacity of the disabled older adults in rural areas, analyze the decline level and influencing factors of their mobility, vitality, cognition, sensory and psychological ability, and further verify the quantitative accuracy and sensitivity of the intrinsic capacity assessment system in the Chinese elderly population. Using the Intrinsic Capacity Assessment System, a questionnaire survey was conducted among 343 disabled rural older adults from 32 conveniently selected villages under Henan Province, China. The average score of intrinsic capacity among disabled rural older adults was (5.68 ± 1.62), and the scores of each dimension were as follows: mobility (4.51 ± 2.72), vitality (22.27 ± 4.02), cognition (17.31 ± 7.09), psychology (6.68 ± 5.69), sensory ability (1.22 ± 0.52), mobility (99.1%) and cognitive (91.0%) ability impairment rates were higher, and the disability level (Cramer’s V 0.444) and frailty status (Cramer’s V = 0.408) were moderately correlated with the level of intrinsic capacity. The results of multiple linear regression analysis showed that age, education level, type of medication, disability level, grip strength level and BMI grade were the influencing factors of intrinsic capacity of the disabled older adults in rural areas (P < 0.05). The intrinsic capacities such as mobility and cognition of disabled rural older adults are severely impaired, and these impairments are influenced by multiple factors including sociodemographic characteristics and personal health status. Subsequently, a multi-domain integrated care plan can be formulated targeting the declining trends in various areas, supplemented by multi-component exercises and a diverse diet to enhance the intrinsic capacity level.

Two-dimensional (2D) nanofluidic membranes with precise ion transport kinetics hold transformative potential for next-generation ion-selective membranes, yet their practical implementation in osmotic energy conversion remains constrained by inherent material limitations.While naturally abundant clay-based 2D nanofluidics show promise for energy harvesting applications, conventional montmorillonite (MMT) systems suffer from insufficient surface charge modulation.Here, we present a plasmon-enhanced molybdenum oxide/montmorillonite (MoO 3 /MMT) nanofluidic composite membrane that synergistically combines charge engineering and photothermal conversion for breakthrough osmotic energy harvesting.Density functional theory (DFT) calculations reveal the additional cation capture sites generated by oxygen vacancies enhance Na + adsorption characteristics at the heterointerface, while the embedded MoO 3 nanophase establishes a stable space charge region and introduces tunable surface charge dynamics through plasmon resonance effects.The optimized nanofluidic architecture maintains stable performance across diverse operational scenarios such as extreme pH conditions (pH 4-10), high salinity environments (up to 3 M KCl), and a wide range of ions of different sizes and charges.Remarkably, the composite membrane achieves a record power density of 10.47 W/m 2 under 50-
