Solid-state lithium metal batteries (SLMBs) demand quasi-solid polymer electrolytes (QSSPEs) that simultaneously deliver high ionic conductivity, interfacial stability, and oxidative resistance. This study reports a QSSPE membrane (MP46) formulated with MG30:LiTFSI:succinonitrile at a 10:4:6 weight ratio, exhibiting a wide electrochemical window of 5.1 V. Complementary infrared spectroscopy, small-angle X-ray scattering, and electron microscopy reveal a hierarchical ionic conductive network consisting of sphere-like nanostructures embedded within microphase-segregated architectures. This morphology enhances lithium-ion transport while preserving mechanical integrity. The strong interfacial adhesion between MP46 and lithium metal enables stable lithium plating and stripping for over 800 h at 0.2 mA·cm–2, effectively mitigating dendrite formation. When paired with LiFePO4 and LiCoO2 cathodes, MP46 sustains prolonged cycling, retaining 80.1% capacity after 1400 cycles at 2 C and 92.1% after 200 cycles at 4.5 V, respectively. Pouch-type cells further demonstrate mechanical flexibility and operational safety under deformation. These results establish MP46 as a viable candidate for stable high-energy-density SLMBs, offering fundamental insights into the design of next-generation polymer electrolytes.

Red mud, a highly alkaline industrial solid waste from alumina production, poses severe environmental risks due to its high alkalinity, low organic matter content, and poor aggregation, which critically impede its soil reconstruction and ecological utilization. This study proposes a novel approach of low-temperature micro-oxidation to drive the synergistic soil reconstruction of red mud and coal. By constructing a low-temperature micro-oxidation atmosphere, the soil properties of the reaction products were investigated, the decomposition and reconstruction of alkaline minerals and alkali release were analyzed, and the oxidation of carbon-based minerals and organic matter transformation in coal were examined. The mechanism of the synergistic reaction between red mud and coal under low-temperature micro-oxidation was elucidated. Results showed that at 250 °C under micro-oxidation, the pH of the product decreased to 8.47, organic matter content increased to 12.98%, and the proportion of aggregates >0.250 mm increased. Alkaline minerals such as cancrinite and grossular in red mud underwent decomposition and reconstruction in the low-temperature hydrothermal environment, releasing substantial free alkali. The condensed aromatic rings of carbon-based minerals in coal were oxidized by free radicals, leading to ring-opening and bond cleavage, producing small-molecule organic acids and macromolecular humic acids. The continuous oxidation of carbon-based minerals in coal generated acids, which neutralized the alkali released from red mud, driving sustained dealkalization. The inorganic particles of red mud flocculated with macromolecular humic acids, forming micro-aggregates and significantly improving soil properties. This research provides technical support for the rapid ecological utilization of red mud at industrial scale.

The Minjiang River Basin, subjected to combined pollution from domestic, agricultural, and industrial sources, has become a typical sensitive area for studying the environmental behavior of emerging contaminants such as antibiotics. This study conducted a cross-year comparative analysis of the composition and concentrations of antibiotics in water samples from nine sampling sites during the dry season in November 2022 and 2024. The findings revealed: 1) After the implementation of the "National Action Plan for Reducing Antimicrobial Use in Livestock", the detection concentrations of tetracycline antibiotics (TCs) decreased (e.g., doxycycline concentrations dropped from 7.75 ng/L to undetectable levels), and the mixed risk quotient (MRQ) across the entire basin transitioned from medium to low risk. However, lincomycin (up to 4.6 ng/L), clarithromycin (1.3 ng/L), and florfenicol (0.6 ng/L) have emerged, indicating an increasing hidden ecological risk from substitution. 2) High-concentration antibiotic zones transferred from urban residential areas in 2022 to intensive aquaculture zones and upstream reservoir areas in 2024. The reduction in dry-season water flow intensified pollutant accumulation, synergistically enhancing the effects of tidal drag. Additionally, the conversion of agricultural land to aquaculture ponds led to increased use of alternative drugs (e.g., sulfamethazine), while policy interventions mitigated the exacerbation of urban antibiotic pollution by construction land. This study elucidates the migration patterns of antibiotic pollution under the synergistic effects of policy regulation and natural processes, emphasizing the need to address hidden risks of substitute drugs and the driving role of land-use changes, providing scientific basis for watershed-scale risk assessment and precise management of emerging pollutants.

Wearable medical monitoring devices require conformal, long-term tissue integration, yet conventional rigid electronics fail to accommodate dynamic tissue deformation. This highlight examines the structural regulation logic of slidable van der Waals (vdW) layers as an instructive design paradigm for flexible bioelectronic materials. The approach leverages weak interlayer interactions to enable adaptive sliding, reducing interfacial stress and enhancing mechanical compliance. Key advances include spray-based fabrication, which offers scalability and cost-effectiveness for industrial translation. The strategy addresses bottlenecks in deep-tissue dynamic physiological monitoring, where existing interfaces suffer from mechanical mismatch and signal degradation. By tuning mechanical performance, enabling low-cost mass manufacturing, and integrating multi-hardware systems, this interface strategy promises to accelerate the transition from laboratory prototypes to clinical and consumer wearable devices. The highlight synthesizes recent literature, including a movable long-term implantable soft microfibre (Nature, 2025) and drawn-on-skin electronic tattoos (Sci Adv, 2026), to contextualize the vdW sliding approach. Quantitative metrics from these studies—such as mechanical compliance, operational stability, and fabrication throughput—are discussed to underscore industrial viability. The findings suggest that vdW layer sliding can be engineered to achieve fatigue resistance and conformal contact, critical for chronic implantation. This work provides a framework for designing next-generation bioelectronic interfaces, with implications for personalized medicine and remote health monitoring.
