Thermodynamic and electrochemical chemical kinetics instability between the electrode/electrolyte interface, resulting from bulk structural instability and Li + diffusion kinetics, were the key restraining factors for improving the energy and power density of Ni-rich layered oxide cathodes. These issues had become barriers to enhancing the high temperatures and high rates performance. Herein, a perovskite-phase LaAlO 3 coating was introduced on the pristine NCM811 surface to form a protective layer by a wet chemical method and high temperature solid-state reaction. The robust LaAlO 3 and derived Li 0.5 La 2 Al 0.5 O 4 layer clearly alleviated the residual lithium compounds, side reactions and phase transitions. Compared to the pristine NCM811, The pristine NCM811 coated with 2 wt% LAO 3 displayed the discharge capacities of 200 mAh g − 1 at 0.1 C, the capacity retention of 93.7%, 89.9% and 78.67% at 2.8–4.3 V, 200 cycles, 1 C (25℃), 1 C (50℃) and 10 C (25℃), demonstrating expectative stability and high-rate performance. Particularly, despite NCM811-LAO2 raw material was exposed in the atmosphere for 60 days, the initial capacities less than 5.0% was lost, exhibiting superior shelf performance. These findings underscored the potential of perovskite-phase coating as an effective and scalable surface modification strategy for enhancing the durability and rate capability of Ni-rich layered cathodes.

Perovskite quantum dot-based light-emitting diodes (QLEDs) have been regarded as promising emitters for lighting and displays. However, the operational stability still greatly hinders their practical applications. Here, we introduce ultrathin nano-layered boron nitride (BN) as buried interfacial layer to enhance device stability. As an effective blocking layer, BN not only interacts with perovskite to passivate interface defects and eliminate ion migration channel, but also directly suppresses ion migration. Meanwhile, BN makes exciton recombination behavior and electrical transport properties of perovskite QDs less sensitive to the heat. Resultantly, BN-optimized QLEDs achieved an average EQE of 30.05% and extrapolated operational lifetime T 50 of 25,263 h at an initial luminance ( L 0 ) of 100 cd m −2 , which is 1.7-fold and about 100-fold improvement compared to control devices, respectively. In this work, integrating 2D materials into perovskites through interface engineering provides a pragmatic tactic to enhance the performance of halide perovskite-based LEDs.

In-situ intraparticle mineralization of widespread metalloids in groundwater is challenging but critical for global freshwater security. However, electronic and steric hindrances of complex oxygen-containing configurations prevent efficient oxygen dissociation and mineralization. Here, arsenic oxyanions are selectively and stably mineralized within d -orbital-modulated nanoscale Fe 0 particles following enhanced d-p orbital-coupled oxygen dissociation, yielding ~100% removal efficiency, ~100% electron utilization, and ~94% metalloid intraparticle mineralization as resolved from thousands of single nanoparticles. Universal As, Sb, and Se intraparticle mineralization demonstrate excellent long-term stability (up to 98-fold of conventional nanoscale Fe 0 ) in various groundwater matrices, where σ-bonded species show preferential intraparticle mineralization over π-bonded configurations. Field deployment is verified through macroscale material synthesis, minimal leaching of Fe and S in permeable reactive barriers, and economic advantages. This work establishes targeted d-p orbital-coupled bond dissociation as a transformative paradigm for metalloid-contaminated groundwater remediation and proposes a scalable in-situ remediation strategy that bridges atomic-level precision with field-ready practicality.

Black carbon is a short-lived climate forcer that occurs as a continuum of particulate matter with varying physical, chemical and optical properties. However, current global climate assessments treat black carbon as a single compound, overlooking the distinct properties of its subtypes and introducing substantial uncertainty in determining its climate impact. Here we evaluate the climate relevance of this overlooked heterogeneity using approximately 2,500 thermal–optical measurements of carbon fractions across emission sources to develop a global inventory distinguishing between less light-absorbing char and more light-absorbing soot from 1750 to 2019. We observed an increase in the soot fraction of total anthropogenic black carbon emissions, from 16% in 1750 to 35% in 2019, primarily driven by increased fossil fuel consumption. This shift, aligning with sediment records, suggests that contemporary black carbon emissions possess greater global warming potential per unit mass than those at the onset of the industrial era. Our findings underscore the need to resolve black carbon subtypes in climate models and prioritize soot-rich sources for mitigation.

Neuromorphic nanofluidics rely on nanoconfinement to regulate the ionic temporal dynamics. However, the inherent scales of the spatial interactions at nanoconfined interfaces limits the scalability and flexibility of such ionic neuromorphic devices. Here we report a multiphasic-gel-based ion transporter system with cascaded-heterointerfacial ion traps for soft-matter multistate ionic neuromorphic processing. The approach relies on interionic hierarchical cross-interface retardation and dissipation to induce heterointerface-trap dynamics. The resulting system offers ionic bipolar rectification with ratios exceeding 10 3 and spike-strength-dependent and timing-dependent dual-order plasticity. By integrating temporal short- and long-term memory effects, we show that the system can implement complex ion-based synaptic adaptability and learning rules, and offers multistate ionic neuromorphic processing with an energy consumption as low as 0.61 pJ per spike. We also develop a biohybrid neural circuit by interfacing an in vivo neuro-iontronic processor with the transected sciatic nerve of a rat, achieving bioneuron-driven ionic neuromorphic processing for interneural signal reconfiguration.

Macrophages play pivotal roles at the interface of immune regulation and bone metabolism and frequently exhibit a proinflammatory phenotype that contributes to the osteoporotic microenvironment. We found that dysfunctional macrophages in the osteoporotic niche transferred injured mitochondria to osteoblasts, which was associated with increased cellular senescence and impaired osteogenic function. This detrimental mitochondrial transfer was associated with abnormal accumulation of succinate dehydrogenase (SDH), contributing to maintenance of the proinflammatory phenotype and mitochondrial injury. On the basis of this mechanism, a folate (FA)-modified magnesium–manganese layered double hydroxide (MgMn-LDH) loaded with the SDH inhibitor dimethyl malonate (DMM) was designed to modulate proinflammatory macrophages. This system promoted BNIP3-LC3B-associated mitophagy, which was accompanied by improved mitochondrial quality control, mitochondrial dynamics and mitochondrial transfer capacity. The functional mitochondrial transfer from treated macrophages to neighboring osteoblasts was associated with enhanced osteogenic activity under osteoporotic conditions. Furthermore, MgMn-LDH/DMM@FA treatment significantly ameliorated bone loss and improved bone microarchitecture in ovariectomized mice. Collectively, these findings suggest that mitigating mitochondrial injury and enhancing functional mitochondrial transfer in proinflammatory macrophages may represent a promising strategy for alleviating osteoporosis. An enzyme-active MgMn-LDH-based delivery system provides a potential therapeutic platform for osteoporosis intervention. Graphical abstract

Protein-polysaccharide binary gels often suffer from limited cross-linking density and insufficient control over network compactness and water immobilization. In this study, we developed a myofibrillar protein (MP)/κ-carrageenan (KC)/tannic acid (TA) ternary gel system and investigated how TA concentration and pH regulate polyphenol-mediated network assembly. MP/KC mixtures were incorporated with TA at 0.50–0.65% and the pH was adjusted accordingly. The result shows TA addition promoted MP unfolding and ternary interactions among MP, KC, and TA, resulting in a denser and more continuous gel network. Notably, pH 6.4 provided a favorable charge-balance window for TA-mediated bridging. The gel prepared with 0.60% TA at pH 6.4 exhibited the best water retention, with water holding capacity (WHC) increasing from 48% in the binary control to 73%. Meanwhile, TA addition significantly changed the zeta potential from –18.1 mV to –25.6 mV, indicating enhanced electrostatic stability. Concurrently, reactive sulfhydryl content decreased from 75.6 nmol/mg to 48.3 nmol/mg with increasing TA, while α-helix content dropped from 53 to 38%, confirming TA-induced MP unfolding. Meanwhile, gel porosity decreased from 8.4% in the control group to 2.1%, further confirming the formation of a denser network structure. However, excessive TA addition led to over-cross-linking and network contraction, which increased structural stiffness but reduced water retention. As the concentration of TA continued to increase, WHC decreased to 69%. These findings indicate that pH acts as a molecular switch controlling TA-mediated bridging in MP/KC/TA ternary gels, offering a mechanism-based strategy for designing meat protein gel systems with tunable texture, WHC and microstructure.

Chronic kidney disease (CKD) has become a major global public health issue. Due to its insidious onset and atypical early symptoms, patients often fail to detect it in time and receive effective intervention. Therefore, conducting early screening and diagnosis is of great significance for delaying the progression of renal failure and reducing the burden on patients and society. Combining surface-enhanced Raman scattering (SERS) technology, immunochromatography and artificial intelligence algorithm, this study utilized serum kidney injury molecule-1 (KIM-1) molecule as a key biomarker to construct a serum-based CKD diagnostic model, aiming to achieve efficient and accurate CKD screening. A total of six models were included for comparative analysis, among which the extreme gradient boosting (XGBoost) model successfully achieved precise classification of CKD, with a classification accuracy of 98.42% and an area under the curve (AUC) of 99.96%. Furthermore, leave-one-out cross-validation was used to validate this model, with an overall classification accuracy of 96.79%. These results indicated that the model exhibited good stability and strong robustness. In conclusion, the artificial intelligence-driven immunochromatography SERS biosensing technology with serum KIM-1 molecule as the early warning radar is expected to become a new technical strategy for intelligent early screening and auxiliary diagnosis of CKD.

Biomass-derived vanillin and ethylenediamine were used as raw materials to synthesize Schiff base chain extenders, which were then incorporated into waterborne polyurethane (WPU) systems to fabricate a series of multifunctional composite films (VWPUs) with tunable Schiff base contents. Research results indicate that all VWPU films exhibit excellent mechanical properties, self-healing capabilities, significant UV resistance, and moderate thermal stability. Among them, the VWPU-2 film demonstrated the best repair effect. Benefiting from the dynamic reversible nature of the Schiff base bond (C=N), the material achieved noticeable healing of surface scratches after 2 h of static storage at 60 °C. After 6 h of repair, the mechanical property self-healing efficiency reached 93.5%. Furthermore, the aromatic ring and phenolic hydroxyl structure in vanillin molecules enhance the polyurethane film's absorption capacity in the 280–400 nm wavelength range, resulting in reduced UV transmittance. This study provides a novel and sustainable design approach for constructing multifunctional water-based polyurethanes with both self-healing and UV resistance, where Schiff base dynamic bonds and vanillin-derived functional groups synergistically realize self-healing and UV resistance, opening new avenues for the development of high-performance, eco-friendly polymer materials.

Background Korshinsk peashrub ( Caragana korshinskii Kom.) is a valuable forage shrub for ruminants due to its abundant cell walls. However, its utilization is largely limited by the cross-linked structures of lignocellulose within its cell walls. White rot fungi possess the ability to degrade these resistant cross-linked structures, offering enormous potential to develop cost-effective biopretreatment processes of Korshinsk peashrub. Results Among the white rot fungi evaluated, Dichomitus squalens demonstrated superior efficacy in improving lignocellulose deconstruction and subsequent rumen fermentation of Korshinsk peashrub ( P < 0.05). This fungus preferentially degrades lignin, hemicellulose, and pectin ( P < 0.05), which corresponded to significantly improved enzymatic saccharification, ruminal degradability, and gas production ( P < 0.05). Genomic analysis revealed that D. squalens possesses a comprehensive range of genes encoding ligninolytic enzyme. Elevated activities and expression levels of laccase, manganese peroxidase, esterase, glutathione S -transferase, versatile peroxidase, and hydrogen peroxide-generating enzymes aligned with the disruption of cross-linked structures and increased porosity of Korshinsk peashrub. Furthermore, the extracellular enzyme cocktail from D. squalens exhibited robust lignin‑degrading capability, corroborating its role in selective ligninolysis. Conclusions Pretreatment of Korshinsk peashrub with selective white rot fungi offers a practical approach to valorize this woody biomass as an alternative feedstock for ruminants.

Glycosylation plays a pivotal role in modulating the structure and immunogenicity of viral antigens. Three glycosylation sites on the receptor-binding domain (RBD) of SARS-CoV-2, including N331, N343 (N-linked), and T323 (O-linked), are highly conserved and remain unchanged across multiple variant strains. To investigate their functional relevance, a series of site-directed glycosylation-deficient mutants were generated on the basis of the RBD-dimer antigen of the ZF2001 vaccine (developed by ZFSW Biologics), including N-N331-NA, N-N343-NA, O-T323-NA, and an RBD-NA control. Comparative analyses of glycosylation-deficient RBD variants revealed a site-specific hierarchy in immune modulation. In particular, disruption of the N343 site led to a pronounced reduction in antigen-specific antibody titers and T helper cell-related cytokine responses in immunized mice, whereas mutations at N331 and T323 had more limited effects. Furthermore, glycan profiling using liquid chromatography–tandem mass spectrometry (LC–MS/MS), secondary structure assessment using microfluidic modulation spectroscopy (MMS), and molecular dynamics simulations revealed that the N343 glycan contributes to local structural stability and preserves key antigenic features of the RBD. Together, these results identify N343 as a critical glycosylation hotspot that governs RBD immunogenicity and antigenicity, providing a mechanistic foundation for the structure-based optimization of SARS-CoV-2 vaccines targeting glycan-regulated epitopes.

To improve the durability of reinforced concrete in chloride-rich environments, the corrosion inhibition performance and mechanisms of N,N-dimethylethanolamine (DMEA) and calcium nitrite (CN) were systematically investigated. Their effectiveness was evaluated in simulated concrete pore (SCP) solutions and in reinforced concrete specimens subjected to laboratory wet–dry cycles and marine splash zone exposure. Electrochemical measurements demonstrated that both inhibitors delayed chloride-induced de-passivation of steel, increased the critical chloride threshold, and enhanced passive film stability. Optimal dosages were identified as 1.5 wt% for DMEA and 3.0 wt% for CN. These dosages increased the charge-transfer resistance ( R ct ) from 8.34 × 10 3 Ω·cm 2 (control) to 2.49 × 10 6 and 3.08 × 10 6 Ω·cm 2 , respectively, achieving high corrosion inhibition efficiencies of approximately 99.7%. Furthermore, the critical chloride threshold was increased from 0.17 to 0.34 M for 1.5% DMEA and 1.44 M for 3.0% CN, representing improvements of 1.0 and 7.4 times relative to the control. Surface analyses revealed that DMEA forms a thin, hydroxyl-rich organic layer through surface adsorption, whereas CN promotes the development of a dense, oxide-enriched passive film. Quantum chemical calculations and molecular dynamics simulations further elucidated their distinct inhibition mechanisms: DMEA strongly adsorbs via hydroxyl coordination, forming a physical barrier, while CN facilitates Fe 2+ oxidation to Fe 3+ , thereby stabilizing the passive film. These findings advance the understanding of organic and inorganic corrosion inhibitors in reinforced concrete and provide both theoretical and experimental support for their rational application in aggressive environments.
