The electron transport layer (ETL) is critical in hole-transport-layer-free all-inorganic perovskite solar cells (PSCs). Although ZnO as an ETL exhibits high electron mobility and suitable energy levels, its high surface defect density often leads to interfacial recombination losses. In this study, PbCl 2 was incorporated into the ZnO ETL to passivate interfacial defects and optimize the energy level alignment. PSCs with a structure of FTO/PbCl 2 –ZnO/CsPbBr 3 /Carbon were fabricated. The resulting carbon-based CsPbBr 3 solar cells achieved a power conversion efficiency (PCE) of 7.0%, representing a 40% improvement over devices based on the pristine ZnO ETL. Furthermore, the unencapsulated devices retained 95% of their initial PCE after 60 days of storage under ambient conditions.

Iron trifluoride demonstrates poor performance as a multi-electron conversion positive electrode in conventional ester-based electrolytes, yet exhibits higher capacity retention in ether-based electrolytes. This contrast has long remained unresolved in high-energy-density metal fluoride-lithium batteries. Here, we show that the electrolyte-dependent behavior originates from interfacial anion competition within the cathode-electrolyte interphase. Spectroscopic and electrochemical analyses reveal that anions derived from lithium salts preferentially interact with iron species, governing interfacial conversion pathways and phase evolution. In ether-based electrolytes, lithium sulfide and lithium oxide react with iron to form electrochemically active iron sulfide species, sustaining reversible cycling. In contrast, lithium carbonate formed in ester-based electrolytes leads to inert carbonate-rich iron species, resulting in surface passivation and capacity decay. With prolonged cycling, iron trifluoride gradually evolves into thermodynamically stable iron-based phases, highlighting that interfacial anion chemistry dictates long-term phase evolution and degradation pathways of iron-based fluoride conversion electrodes.

Freshwater lakes are globally significant sources of potent greenhouse gases (GHGs), but how their GHGs emissions respond to changing nutrient levels remains unclear. Here, we demonstrated that nitrous oxide (N 2 O) production pathways in lake sediments are tightly linked to trophic state, whereas methane (CH 4 ) production appears to be multifactorial Through global metagenomics and controlled batch experiments. In eutrophic sediments, N 2 O is efficiently removed through complete denitrification, with nitrification serving as the main production pathway, whereas oligotrophic sediments produce N 2 O primarily via incomplete denitrification. By simulating nutrient transitions using an innovative cross-inoculation experiment, we further revealed that lake sediments systematically shift between these N 2 O production pathways as their trophic state changes, from denitrification-driven to nitrification-dominated during eutrophication, with the inverse pattern during oligotrophication. Consequently, N 2 O emissions can be effectively mitigated by inhibiting nitrification in eutrophic lakes and restricting incomplete denitrification in oligotrophic ones. Our findings establish trophic status as a key driver of N 2 O production sources in lake sediments.

Grape seed extract (GSE) is a polyphenol-rich dietary ingredient, and its compositional complexity poses challenges for precise product quality assessment. At present, GSE quality control mainly relies on spectrophotometric assays that measure bulk indices, such as total polyphenols and total procyanidins. However, these methods cannot readily distinguish low-oligomeric procyanidins from highly polymerized components due to the lack of structural resolution. To enable more specific characterization of key constituents, this study developed and validated an ultra-performance liquid chromatography-ultraviolet detection (UPLC-UV) method for the simultaneous quantification of five phenolic markers: gallic acid (GA), (+)-catechin (C), procyanidin B2 (PCB2), (−)-epicatechin (EC), and procyanidin C1 (PCC1). Using this method, we systematically compared 14 industrial raw materials from different manufacturers and five commercial dietary supplements. The results showed that, among industrial raw materials with label-declared total procyanidins ≥ 95%, the measured concentrations of the target oligomeric markers differed markedly across samples. Analysis of commercial finished products further showed that substantial between-product differences in key components remained evident even after label-context normalization. These findings indicate that chromatographic quantification of structurally specific markers, used as a complement to conventional total-content indices, would provide more detailed compositional information and thereby serve as a valuable supplementary analytical approach for routine quality control of GSE and related products.

Lead is a highly toxic and persistent heavy metal that poses serious risks to human health. The detection of lead ions in water is therefore essential not only for balancing economic and environmental priorities, improving public services, and ensuring agricultural safety, but also for preventing lead poisoning, promoting health equity, and safeguarding international trade in the context of global health. Conventional detection methods are often limited by expensive instrumentation and complex procedures, whereas surface-enhanced Raman scattering (SERS) has emerged as a promising alternative due to its high sensitivity and operational simplicity. In this study, we developed an ultrasensitive SERS-based method for the Pb 2+ detection using L-cysteine-functionalized bismuth nanoparticles as probes. L-cysteine binds Pb 2+ through its −COOH and −NH 2 groups, inducing nanoparticle aggregations and generating Raman hotspots that enhance the signal of 4-aminothiophenol (4-ATP). Additionally, an electrodeposited bismuth substrate further amplifies the SERS response. This method achieves a detection limit as low as 0.005 nmol·L −1 (1.04 · 10 −3 µg·L −1 ), demonstrating 2–5 orders of magnitude greater sensitivity compared to conventional lead ion detection techniques.

The aerospace, military stealth, and 5G communication fields have raised new requirements for multifunctional materials. In this study, a rigid MWCNT/Co@C/rGO/PMI composite foam (MCGP) was prepared using a UV light-initiated in-situ copolymerization hot air foaming method. The sandwich structure of MOF-GO-MOF, after calcination, achieved a uniform dispersion of magnetic Co particles and formed rich hetero interfaces. The 0D Co@C, 1D MWCNT, and 2D rGO formed a multi-dimensional filler system, and the magnetic-electrical synergy and isotropy bubble structure jointly optimized the impedance matching, and multiple loss mechanisms enhanced the absorbing performance. The results showed that M20C20/PMI achieved a RL value of -68.26 dB at a frequency of 8.92 GHz and a thickness of 40mm, and the EAB covered the full frequency band of 2—18 GHz. The RCS value of M25C15/PMI reached a minimum of -45.82 dB·m 2 . Notably, by carefully adjusting the proportion of fillers, the five MCGP composite foams prepared in this study all had a minimum RL value of < -55 dB, basically meeting the requirements of each absorption frequency band. In addition, the MCGP composite foams are lightweight (28.30 kg/m 3 ), have high strength (0.50 MPa), heat insulation (0.02856 W/(m·K)), and infrared stealth characteristics, making them promising as a new generation of integrated structural–functional protective materials.

Proton conducting ceramic cells enable efficient electrocatalytic H 2 -to-power conversion, yet their perovskite air electrodes demand versatile properties: high bulk proton uptake/conductivity, fast surface oxygen kinetics, and operational stability. Conventional single-phase perovskites usually fail to meet these demands simultaneously. Here, we show a facile strategy that couples bulk cation migration with surface segregation to enhance the versatility of the air electrode. The as-prepared (Ba 0.9 Ce 0.1-α )(Ce α Fe 0.8 Ni 0.2-β )O 3-δ -βNiO (cm-BCFN@NiO) electrode features a coupled bulk–surface architecture where finely dispersed NiO nanoparticles and Ce migration from A-sites to B-sites synergistically optimize surface oxygen kinetics, bulk proton uptake/conductivity, and electronic transport. The optimized electrode exhibits a low area-specific resistance of 0.3 Ω cm 2 at 550 °C—a 75% reduction compared to the NiO-free counterpart—enabling a 77.1% increase in maximum power density and over 1200 hours of stable single-cell operation. Beyond protonic ceramic cells, this work presents an approach for designing perovskites by leveraging cation migration and surface segregation at the atomic scale, opening more opportunities for a wide range of electrocatalytic applications.

Thallium (Tl) is a highly toxic heavy metal that accumulates in soils, posing significant risks to soil organisms, but its tissue-specific effects in earthworms remain poorly characterized. We examined the differential responses of the intestine and body wall of Eisenia fetida exposed to 0–60 mg kg⁻¹ Tl-contaminated soils for 28 days. A suite of biomarkers covering oxidative stress, neurotoxicity, ion transport, and digestion was analyzed, and the integrated biomarker response index (IBRv2) was used to assess overall toxicity. Results showed that the intestine responded more rapidly and sensitively than the body wall, with early activation of antioxidant defenses, dynamic GSH modulation, and marked disruption of neuro- and ion-regulatory functions. Digestive enzymes responded divergently, with cellulase activity enhanced but pepsin activity suppressed. IBRv2 analysis confirmed dose- and tissue-dependent effects, consistently identifying the intestine as the primary target of Tl toxicity. Correlation analysis further revealed tissue-specific regulation of antioxidant, neural, and ion transport functions under stress. These findings elucidate tissue-specific mechanisms of Tl toxicity in earthworms and suggest that intestine-targeted biomarkers are sensitive indicators for soil ecological risk assessment.

YAP/TAZ and SMAD1/5 signaling modulate atherosclerosis. These involvements in diabetes-associated endothelial dysfunction remain unexplored, thereby being investigated from different endothelial cells and a total of 102 mice in the current study. Male C57BL/6 mice were fed a high-fat diet (45% kcal% fat, 15 weeks) and orally administered with endoplasmic reticulum (ER) stress alleviator 4-phenylbutyric acid (100 mg·kg –1 ·d –1 ) and jatrorrhizine (50 mg·kg –1 ·d –1 ) for 5 weeks. Endothelial cells were cultured with high glucose, ER stress inducer tunicamycin, ER stress alleviators, YAP inhibitor simvastatin, or jatrorrhizine. The mouse aorta was divided into the aortic arch and thoracic aorta regions to investigate the regional difference. Treatment with PBA and jatrorrhizine ameliorated endothelium-dependent relaxations as well as inhibited ER stress, YAP/TAZ-SMAD1/5 signaling and oxidative stress in aortas. Phosphorylation of YAP/TAZ was highly expressed in the thoracic aorta but low in the aortic arch. On the other hand, phosphorylation of SMAD1/5 was upregulated in the inner curvature of the aortic arch but downregulated in the thoracic aorta. In HUVECs, ER stress alleviators significantly inhibited YAP/TAZ-SMAD1/5 signaling and increased NO bioavailability, but the YAP inhibitor did not suppress ER stress. Inhibition of YAP/TAZ downregulated SMAD1/5 signaling under high glucose stimulation, followed by the Akt/eNOS pathway. YAP/TAZ directly interacts with SMAD1/5, and their binding is significantly enhanced under high-glucose conditions. A natural compound, jatrorrhizine, was identified to inhibit YAP/TAZ-SMAD1/5 signaling and protect vascular function in diabetes. To conclude, ER stress activates YAP/TAZ and SMAD1/5 signaling, resulting in endothelial dysfunction in diabetes. Inhibition of YAP/TAZ-SMAD1/5, such as by ER stress alleviators and natural product jatrorrhizine, ameliorates endothelial dysfunction associated with diabetes. These findings support the cross-talk between ER stress and YAP/TAZ-SMAD1/5 as well as their potential as therapeutic targets.

Wood panels are extensively applied in furniture, construction fields, where their versatility and cost-effectiveness make them indispensable, but their assembly relies on adhesives that emit toxic formaldehyde, demand energy-intensive curing, and form weak interfacial bonds. Inspired by wood’s self-repair via cellulose microfibril reorganization, we develop a cellulose-based homologous active adhesive (HAA) derived from wood components. HAA cures under ambient hydration, eliminating toxic emissions and reducing energy consumption by >80%. Its mechanism activates wood surface hydroxyl groups and regenerates cellulose to create a seamless transition layer that enhances load transfer and resistance. This architecture enables specific bonding strength up to 100× greater than conventional adhesives, despite ultra-low solid content (<5%). Using molecular dynamics simulations, AFM nanomechanics, spectroscopy, and life-cycle assessment, we reveal that HAA outperforms commercial resins, offering pot life >30 days, full biodegradability, and >70% lower environmental impacts. HAA establishes a biomimetic, circular pathway for sustainable, high-strength wood bonding.

Obesity can be classified into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO), but the molecular mechanisms remain unclear. We identify geranylgeranyl pyrophosphate (GGPP), a metabolite of the hepatic mevalonate pathway involved in cholesterol biosynthesis, as a critical mediator that distinguishes MUO from MHO. In this study, Long-term feeding of mice with starch oleate significantly upregulated the expression of geranylgeranyl diphosphate synthase (Ggpps), resulting in elevated GGPP levels. Liver-specific deletion of Ggpps reduced GGPP and selectively attenuated adipocyte hypotrophy while specifically enhancing insulin sensitivity in epididymal white adipose tissue (eWAT). Mechanistic studies suggest that GGPP modulates acyl-CoA synthetase long-chain family member 1 (ACSL1) in eWAT through non-covalent binding rather than protein geranylgeranylation, thereby inhibiting its translocation from the endoplasmic reticulum to mitochondria. The retention of ACSL1 in the ER induces eWAT-specific adipose remodeling by promoting triglyceride (TG) synthesis and suppressing lipid oxidation. These findings establish a “liver-adipose” axis mediated by the hepatic metabolite GGPP via its non-covalent interaction with adipocyte ACSL1, highlighting potential therapeutic targets for metabolic dysfunction associated with metabolically unhealthy obesity.

Acidic electrochemical CO 2 reduction (CO 2 RR) typically requires K + ions to create a local H + -depleted microenvironment, suppressing competing hydrogen evolution reaction (HER). Excessive localized K + causes salt precipitation, compromising electrolysis stability. Achieving stable operation with high Faradaic efficiency (FE) at low K + concentrations remains a crucial challenge for conventional nanomaterials. Inspired by water-trapping function of sponges, we design a three-dimensional interconnected porous cubic SnO 2 electrocatalyst (SnO 2 sponge) that confines OH – within porous channels to consume proton influx from the bulk, enabling durable acidic CO 2 RR towards formic acid (HCOOH). Theoretical and experimental studies reveal the SnO 2 sponge sustains substantially higher OH – concentration than dispersed SnO 2 nanoparticles. At pH 1.82, the SnO 2 sponge achieves 94.5% FE HCOOH at 800 mA cm –2 . With only 0.075 M K + , it retains 95.2% FE HCOOH at 400 mA cm –2 . Notably, it enables continuous HCOOH production at 400 mA cm –2 with 97.7% FE HCOOH for over 390 h without cleaning. This work provides a promising strategy for durable and efficient CO 2 RR in acidic media with low K + concentrations.
