Conventional eye-movement interaction systems depend on video capture, infrared tracking, and image recognition, which impose inherent constraints on accuracy, response latency, and stability. This study introduces an eyelash-guided signal interaction system based on a triboelectric nanogenerator (PF-TENG) using PDMS-FDTS thin films. The system employs eyelash movements as interactive inputs, eliminating the need for complex optical acquisition devices. A CNN-LSTM hybrid neural network classifies distinct eyelash movement patterns with a classification accuracy exceeding 98.5%. The PF-TENG device exhibits ultra-flexibility and transparency, enabling seamless integration onto eyeglasses without obstructing the user's field of view. Experimental validation demonstrates real-time monitoring of ocular states for driving fatigue detection, accurately identifying fatigue signs and enhancing application potential in intelligent driving. The system offers a natural, comfortable input modality and significant advantages for human-machine interaction, with broad prospects in eye-movement control and intelligent transportation.

Room-temperature phosphorescence (RTP) polymer materials are attractive for flexible electronics and information encryption due to their tunability and processability. However, achieving polymeric RTP systems that simultaneously exhibit high thermal sensitivity, reversible multicolor emission, and long phosphorescence lifetime (τPhos) with high quantum yield (ΦPhos) remains challenging. Here, we report an in-situ cross-linked self-assembly strategy that converts flexible polymers into rigid polymer microspheres, yielding long τPhos, high ΦPhos, and thermally and time-dependent tunable RTP. The resulting microspheres (PM0.1-0.01-1) exhibit a maximum τPhos of 1754 ms and ΦPhos of 42.83%, markedly superior to previously reported intrinsic polymer RTP materials. At 77 K, they display ultralong green emission with a lifetime of 6019 ms and visible afterglow lasting up to 99 s. The cross-linked microspheres enable time-dependent, continuously tunable RTP and thermally responsive color switching, while maintaining excellent phosphorescence stability in aqueous and high-temperature environments. This provides a versatile platform for dynamic information encryption, full-color afterglow LEDs, and temperature sensing. The strategy establishes a general design principle for developing multidimensional, controllable, and stable high-performance polymer RTP materials.

Bismuth telluride (Bi2Te3)-based alloys remain the benchmark for low-temperature thermoelectric applications, yet their conversion efficiency is limited by the trade-off between electrical and thermal transport. This study introduces a pseudo grain boundary engineering strategy to simultaneously enhance the average figure of merit (ZT) in p-type (Bi,Sb)2Te3 (BST) materials. By incorporating Ag-based compounds, the carrier concentration is optimized via substitution of Ag+ ions, while the introduction of secondary phases at grain boundaries effectively suppresses lattice thermal conductivity. The approach yields a peak ZT of 1.35 at 393 K and an average ZT of 1.25 across 303–483 K, representing a significant improvement over pristine BST. Compared to prior reports, this work achieves superior average ZT while maintaining high electrical conductivity, addressing the longstanding bottleneck of thermal conductivity reduction without compromising carrier mobility. The findings underscore the efficacy of pseudo grain boundary engineering in advancing Bi2Te3-based thermoelectrics for solid-state cooling and power generation.

The precise and controllable synthesis of one-dimensional (1D) and two-dimensional (2D) heterostructures, coupled with the manipulation of their atomic and electronic configurations, is of paramount significance. However, due to the synthetic challenges associated with graphyne (GY) materials, their integration into 1D/2D heterostructures remains considerably difficult. Herein, we demonstrate a post-synthetic intercalation strategy for tellurium onto Ag(111), enabling the controllable fabrication of 1D-GY-nanowire/2D-AgTe-monolayers heterostructures. Scanning-probe microscopies are employed to characterize morphological evolution during the intercalation process. Scanning tunneling spectroscopy results confirm that AgTe monolayer intercalation induces interfacial decoupling of the graphyne nanowires. Density functional theory calculations demonstrate that work function-driven Fermi level modulation via interfacial charge engineering assigns the 1D-GY-nanowire/2D-AgTe-monolayers heterostructures as type-I heterostructures. Our work not only significantly advances the fundamental understanding of interfacial interactions in 1D/2D heterostructures but also presents a scalable strategy for designing heterostructures with tailored electronic functionalities, thereby opening new avenues for applications in advanced nanoelectronics and optoelectronic devices.

Lipid peroxyl radicals (ROO·) are terminal propagating species in lipid peroxidation, driving oxidative damage in neurological disorders. Their prolonged lifetime and rapid diffusion within lipid membranes render them difficult to neutralize. Here, we report a bioelectric-responsive TEMPO-doped polydopamine (PDA@TEMPO) nanozyme that sustains catalytic interception of ROO· radicals under persistent oxidative stress. By coupling a PDA redox reservoir with TEMPO catalytic centers, the nanozyme establishes a self-regenerating radical-neutralization cycle via proton-coupled electron transfer (PCET). The π-conjugated framework facilitates charge migration and enables an electric-field-enhanced antioxidant response. In a seizure model, the nanozyme dynamically responds to bioelectric fluctuations, accelerating radical interception and alleviating oxidative stress in neural microenvironments. These findings establish bioelectric-coupled nanozymes as a general strategy for catalytic and sustained regulation of oxidative stress in neural microenvironments, providing a potential therapeutic approach for neurological disorders.

Organic light-emitting diodes (OLEDs) are an advanced technology for full-color displays, yet the low efficiency of blue OLEDs remains a critical bottleneck. Here, we report a new strategy to design robust Pt(II) emitters with enhanced molecular rigidity and increased locally excited character. The resulting Pt(II) emitter exhibits an extremely narrow emission spectrum peaking at 458.6 nm with a full-width at half-maximum (FWHM) of 16.0 nm and a small Huang-Rhys factor of 0.278, together with a high photoluminescence quantum efficiency of 95%. When doped into an OLED, the device emits at 464 nm with high color purity (FWHM = 19 nm) and achieves high external quantum efficiencies (EQEs) of 32.6%, 29.4%, and 26.9% at luminances of 123, 1000, and 5000 cd/m2, respectively. Notably, the device attains a record-high maximum brightness of 84,895 cd/m2 among reported deep-blue OLEDs with Commission Internationale de l'Éclairage (CIE) y-coordinate < 0.15. This work demonstrates one of the highest-performing deep-blue OLEDs reported to date, addressing the dual challenges of efficiency and brightness in this spectral region.

Chromium oxides (CrOx) and fluorinated graphite (CFx) are two typical cathode materials for lithium primary batteries. The former possesses the highest theoretical energy density but suffers from low practical capacity and inferior rate capability; the latter has the highest theoretical discharge capacity but fails to support fast discharge. Combining the merits of both cathodes via a composite design is desirable, yet the electrochemical performance of such composites remains unsatisfactory. In this work, we identified that by regulating the overlapped discharge potential of these two cathodes, fluorine atoms migrate from CFx to CrOx, leading to a homogeneous distribution of LiF and improved ionic and electronic conductivity, ultimately enhancing high-rate discharge performance. Benefiting from this synergetic effect, the CrOx/10%eCFx composite exhibits a considerably high energy density of 496.59 Wh kg−1 at a power density of 49.7 kW kg−1 (50 C), far superior to pure CrOx and CFx electrodes. We believe that the high-performance CrOx/eCFx composite cathode will justify its practical application in revitalizing advanced lithium primary batteries.

Aprotic lithium-oxygen (Li-O2) batteries are severely limited by slow cathode reaction kinetics and large polarization. Herein, we design and prepare a Mott-Schottky catalyst by uniformly embedding ultrafine Ru nanoparticles on nitrogen-doped carbon (Ru@NC) nanoflakes to accelerate oxygen redox kinetics of Li-O2 batteries. The Mott-Schottky effect of Ru@NC drives spontaneous electron rearrangement in the NC matrix and induces a strong built-in electric field at heterointerfaces, which accelerates the activation and conversion of oxygen intermediates. The obtained Ru@NC possesses rich Mott-Schottky heterointerfaces and defective carbon structures, which provide extensive adsorption and nucleation sites. More importantly, Ru@NC manifests moderate affinity for the intermediate LiO2, inducing formation of unique nanosheet-like Li2O2 with low Li2O2/cathode interfacial impedance, which further enhances oxidation kinetics. These enable the Li-O2 battery with Ru@NC to deliver a remarkably reduced polarization of 0.89 V, superior rate performance, and prolonged lifespan of over 200 cycles. This work will provide valuable guidelines for engineering advanced electrocatalysts for high-performance Li-O2 batteries and beyond.

Pore-tuning engineering is an effective strategy for designing catalysts for energy storage and conversion. Here, we report a rhombic dodecahedral iron and nitrogen co-doped carbon (Fe-N-C) material with hierarchical micro-mesoporous structures, synthesized using mesoporous silica as both pore template and iron source. The resulting catalyst (m-Fe/NC) exhibits significantly enhanced oxygen reduction reaction (ORR) activity, with half-wave potentials of 0.81 V and 0.88 V in acidic and alkaline media, respectively. When employed as a cathode in zinc-air batteries, m-Fe/NC delivers a superior specific capacity of 815 mAh g_Zn^-1 and a stable cell voltage of 1.31 V at a current density of 10 mA cm^-2. Advanced characterization and theoretical calculations reveal that the mesoporous structure not only increases active site exposure but also induces a curvature-induced strain effect on concave surfaces, which enhances intrinsic activity. This work provides insights for developing innovative nanoporous electrocatalysts.

The proliferation of 5G communications and smart electronic devices has intensified electromagnetic wave (EMW) pollution, necessitating microwave absorption materials (MAMs) with high efficiency, lightweight, and flexibility. Traditional MAMs suffer from high density and narrow effective absorption bandwidth (EAB). This work presents a lightweight, flexible microwave-absorbing composite fabricated by in-situ polymerization foaming of polyurethane (PU) with multi-walled carbon nanotubes (MWCNTs) and flaky carbonyl iron (FCI). The hierarchical PU composite foam, designated 3*PFC 0.5-1.0-1.5, achieves an EAB of 15.7 GHz, covering 98.1% of the tested 2–18 GHz range, including S, C, X, and Ku bands. This performance stems from synergistic conductive and magnetic losses, along with impedance matching facilitated by the hierarchical porous structure. The composite maintains low density and high compressibility, offering a promising solution for EMW absorption in 5G, military stealth, and smart devices. The in-situ method ensures strong interfacial adhesion between fillers and matrix, enhancing durability compared to impregnation methods. This study demonstrates a scalable approach to fabricate high-performance MAMs with broad bandwidth and mechanical robustness.

Embedding a dielectric layer between as-synthesized graphene nanoribbons (GNRs) and metal surfaces represents a powerful strategy to achieve electronic decoupling, thereby enabling the extraction of these ribbons' intrinsic electrical properties. Although several reports have documented dielectric intercalation between GNRs and metal substrates, studies on Ag(111) substrates are limited. Here, we demonstrate a semiconducting AgTe monolayer intercalation method to achieve electronic decoupling between as-synthesized GNRs and an Ag(111) substrate. Using low-temperature scanning tunneling microscopy, we directly observed the AgTe intercalation process at the GNR/Ag(111) interface. By combining scanning tunneling spectroscopy and density functional theory calculations, we elucidate the critical role of AgTe monolayer intercalation in reducing the interaction between as-synthesized GNRs and the Ag(111) substrate and observe the near-intrinsic electrical properties of the GNRs. Our findings offer a practical and effective strategy for intercalating AgTe monolayers between carbon-based nanomaterials and Ag(111) substrates, facilitating the unambiguous characterization of the near-intrinsic electronic properties of these materials.

Hydrogen production by photosynthetic green algae is an efficient biological process that utilizes light energy to convert water and carbon dioxide into clean and renewable energy. In this paper, we constructed a hybrid system combining graphitic carbon nitride (g-C3N4) and Chlorella pyrenoidosa (Chlorella), in which g-C3N4 serves as an extracellular electron source and Chlorella acts as a biological reactor for specific hydrogen production. In particular, the electronic structure of carbon nitride was optimized by means of hydrothermal alkalization and copper ion doping, expanded the light absorption range and enhanced the light response ability. g-C3N4, as an extracellular electron source, can provide electrons for Chlorella to improve hydrogen production performance which is 3.7 times that of bare Chlorella. The construction of a biological hybrid system is a feasible optimization strategy for the hybrid system to promote the synergistic effect of the hybrid system by regulating the properties of non-living components.

This study presents a novel electrochemical sensor for the rapid detection of trace lead ions (Pb(II)) in water, utilizing a rod-shaped bismuth-based electrode. The electrode was fabricated by modifying a glassy carbon electrode (GCE) with basic bismuth nitrate [Bi6O5(OH)3](NO3)5·3H2O, synthesized via a chemical precipitation method. The sensor was characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), electron probe microanalysis (EPMA), and energy-dispersive X-ray spectroscopy (EDS), confirming the rod-like morphology and composition. Electrochemical detection was performed using differential pulse voltammetry (DPV) in a 0.1 mol·L−1 NaAc-HAc buffer (pH 4.3). The sensor exhibited a linear detection range for Pb(II) from 1 to 90 μg·L−1, with a detection limit of 0.34 μg·L−1 and a sensitivity of 106 μA·(μmol·L−1)−1. The electrode demonstrated excellent anti-interference capability and reproducibility. Recovery tests in real water samples (tap water and campus lake water) yielded high recovery rates, indicating practical applicability. This work provides a simple, cost-effective, and reliable method for monitoring trace Pb(II) in environmental water, particularly relevant for public swimming pools and similar aquatic facilities.

Carboxyl-modified polystyrene microplastics (PS-COOH) are negatively charged particles formed by surface oxidation and functional group modification of polystyrene microplastics (PS), widely used in biomedical and analytical chemistry. However, studies on their neurotoxic effects on aquatic organisms are scarce. This study employed zebrafish (Danio rerio) as a model organism, exposing embryos to environmentally relevant concentrations (0.1, 1, 10, 100 μg·L−1) of PS and PS-COOH. Neurotoxic effects were assessed by measuring tail coiling frequency at 24 hpf and swimming velocity under alternating light/dark cycles at 120 hpf. Results demonstrated that both PS and PS-COOH induced neurotoxicity, with PS-COOH significantly reducing tail coiling frequency and average swimming speed compared to PS (P<0.05). Exposure to 10 μg·L−1 PS-COOH disrupted neurotransmitter homeostasis, altering levels of acetylcholine (ACh), serotonin (5-HT), and γ-aminobutyric acid (GABA). Transgenic zebrafish Tg(huc:EGFP) fluorescence assays revealed that PS-COOH (0.1–100 μg·L−1) caused damage to central neurons. These findings indicate that PS-COOH exposure impairs cholinergic, serotonergic, and GABAergic neurotransmission, induces neuronal damage, and exerts neurotoxic effects on zebrafish larvae. This study provides a theoretical basis for assessing the ecological and health risks of modified microplastics.

Acetamiprid, a representative neonicotinoid insecticide, persists in soil and water, posing ecological risks. This study evaluated its transgenerational toxicity in Caenorhabditis elegans exposed to 1, 10, and 100 μg·L−1. Direct exposure (F0) caused neurobehavioral abnormalities, with head swing frequency significantly increased by 23.86% even at 1.0 μg·L−1, correlating with disrupted acetylcholinesterase and γ-aminobutyric acid. Reproduction, development, metabolism, and intestinal barrier were impaired, with reactive oxygen species elevated by 30.42%–48.28%, indicating oxidative stress as a mechanism. Effects transmitted to unexposed T1–T3 generations: at 1.0 μg·L−1, body width inhibition persisted to T2; fat accumulation and intestinal permeability effects intensified with concentration. Among oxidative stress biomarkers, superoxide dismutase showed highest sensitivity and transgenerational persistence. This study reveals multidimensional transgenerational toxicity, informing soil ecological risk assessment of neonicotinoids.

Selenium (Se) is an essential trace element for human health, and dietary intake through Se-rich crops is the primary route. However, total soil Se content does not directly reflect the bioavailability to plants, which depends largely on soil available Se. This study, conducted in Shipai Town, Longshan County, Hunan Province, used 1:50,000 land quality geochemical survey data to investigate factors influencing the Se bioaccumulation coefficient in maize kernels. Soil pH, CaO, and MgO were identified as significantly positively correlated with the bioaccumulation coefficient and were selected as proxies for soil available Se. A random forest (RF) model was developed to predict maize grain Se content and assess the feasibility of cultivating Se-rich maize in low-Se farmland. Results showed that although soil Se was deficient, 53.64% of maize grain samples met the Se-rich product standard (0.02–0.30 mg·kg−1). Compared with multiple linear regression, the RF model exhibited higher accuracy and reliability. The RF model predicted that 40.91% of farmland in the study area is suitable for natural Se-rich maize cultivation, representing a 25.86% increase over the area identified by soil total Se alone. This study provides a novel methodological framework for planting natural Se-rich maize in Se-deficient regions, validating the potential for such cultivation.

Anoxygenic photosynthetic bacteria (APB) are a phylogenetically diverse group of prokaryotes that perform photosynthesis without oxygen evolution. They possess versatile metabolic capabilities, including anaerobic photophosphorylation, carbon fixation, multi-substrate metabolism, and metal oxidation-reduction, enabling them to thrive in diverse environments such as lakes, rivers, soils, salt lakes, and hot springs. APB play a pivotal role in biogeochemical cycling of carbon, nitrogen, sulfur, and metals. This review systematically summarizes the metabolic diversity of APB, emphasizing their ability to utilize organic and inorganic compounds as electron donors and carbon sources. We highlight recent advances in understanding extracellular electron transfer (EET) mediated by exogenous electron shuttles and conductive materials, which expand the electron sources available for energy generation and reducing power. In environmental engineering, APB show promise in carbon sequestration, pollutant degradation (including azo dyes and heavy metals), biohydrogen production, and microbial fuel cells. For instance, Rhodopseudomonas palustris can fix CO2 under dark anoxic conditions via syntrophic interspecies electron transfer, achieving enhanced carbon fixation. Additionally, APB-based biohybrid systems incorporating CdS nanoparticles demonstrate light-driven degradation of azo dyes without external electron donors. Challenges remain in scaling up these technologies, optimizing reactor conditions, and understanding metabolic regulation. Future research should focus on genetic engineering to enhance APB performance and integrating APB into circular bioeconomy frameworks.

Fluoride-containing wastewater treatment typically relies on calcium-based precipitation and flocculation, which suffer from low compliance rates and difficult valorization of fluoride-laden sludge. This study introduces a novel bismuth upconversion luminescent glass (BULG) synthesized from Bi2O3, SiO2, Yb2O3, and Er2O3, designed for efficient fluoride removal and subsequent photocatalytic application. By varying the Bi2O3:SiO2 molar ratio, a series of BULGs with superior upconversion luminescence were obtained. Under optimal conditions (Bi3+:F− molar ratio = 1:1, pH = 2), fluoride removal efficiencies exceeded 97% for all compositions, with the 0.7:0.3 Bi2O3:SiO2 formulation achieving 99.9% removal and rapid settling of the precipitate. The fluoride removal products retained upconversion luminescence and exhibited semiconductor heterojunctions, enabling complete photocatalytic degradation of ciprofloxacin (100% within 60 min). This approach not only efficiently removes fluoride ions but also valorizes the waste into a functional photocatalyst, offering a promising strategy for fluoride-containing wastewater treatment.

The escalating thermal management demands of modern electronics necessitate materials with superior thermal conductivity and matched thermal expansion. Cu/Diamond composites are promising, yet their fabrication typically requires extreme conditions (high temperature/pressure) or complex coating processes. This work introduces a one-step, heat-source-free cold manufacturing method using ultrasonic vibration to consolidate Cu/Diamond composites at room temperature and a low pressure of ~16 MPa within seconds. The applied pressure is reduced by 200–500 times, and the required temperature is only 20% of that used in conventional high-temperature high-pressure sintering. Direct metallurgical bonding at Cu-Cu interfaces and solid embedding of diamond particles in the Cu matrix are achieved, yielding a composite with a high yield strength of 150 MPa. The method enables a maximum diamond proportion of ~60%, resulting in a thermal conductivity exceeding 1043 W/(m·K) and a coefficient of thermal expansion below 10×10⁻⁶ K⁻¹. Complex shapes are readily fabricated, and heat dissipation tests demonstrate superior performance compared to commercial Al₂O₃ and AlN substrates. The loose preparation conditions and rapid processing confer significant industrial production potential.

Microplastics (MPs) are frequently detected in various water bodies, posing increasing environmental risks. This study synthesized magnetic Fe3O4@MIL-100(Fe) microspheres via an in-situ one-step hydrothermal method and investigated their adsorption removal mechanisms for polystyrene (PS) and polylactic acid (PLA) microplastics. The composite exhibited a core-shell structure with a high specific surface area of 848.6 m2·g−1. Adsorption kinetics showed that PLA followed a pseudo-second-order model, while PS fitted both pseudo-first-order and pseudo-second-order models. Equilibrium data for both MPs were well described by the Freundlich isotherm. Removal efficiencies for PLA and PS increased from 58.18% and 49.66% to 98.90% and 98.58%, respectively, as pH decreased, and from 64.24% and 21.58% to 97.05% and 94.63% with increasing ionic strength. The removal mechanism involved synergistic physical-chemical interactions: hydrogen bonding dominated for PLA, with some complexation, while π–π interactions and hydrogen bonding were primary for PS. The material demonstrated excellent reusability over multiple cycles. These findings highlight the potential of Fe3O4@MIL-100(Fe) for efficient removal of MPs from water, offering a novel approach for controlling emerging contaminants.

Photochemical organic synthesis exploits the distinctive redox properties of excited-state photocatalysts to avoid stoichiometric redox reagents, enabling green and sustainable transformations. However, the conversion efficiency of light-to-chemical energy remains a key bottleneck for large-scale application. Here, we synthesize ultra-thin graphitic carbon nitride (g-C3N4) nanosheets by regulating precursor types and thermal protocols. In photochemical Minisci-type cross-couplings, this ultra-thin carbon nitride exhibits high catalytic efficiency, achieving rates of 40 mmol g_cat−1 h−1 under LED irradiation and 10.9 mmol g_cat−1 h−1 under natural sunlight. The photocatalyst's high specific surface area (120 m2 g−1) enhances substrate adsorption capacity and accelerates surface electron transfer, boosting photocatalytic efficiency. Furthermore, the material demonstrates excellent recycling stability, and the reaction system was successfully scaled to gram-level, highlighting its potential for industrial applications. This work provides a typical case for solar-driven organic synthesis and inspires further developments in heterogeneous photocatalysis.

Perovskite photolithography, an emerging research frontier, combines the unique properties of perovskite materials with lithographic processes for advanced optoelectronic applications. Currently, bottom-up photolithography is preferred due to perovskites’ intrinsic characteristics, while top-down photolithography offers better compatibility with mature semiconductor manufacturing workflows. In this study, we innovatively propose an integrated technology that merges top-down photolithography with in situ phase-transition strategy. Utilizing non-emissive Cs4PbBr6 perovskite single crystals (SCs) as both structural templates and reaction sources, we achieve spatially selective patterning by precise wet and dry etching, followed by inductively coupled plasma (ICP)-induced Cs4PbBr6 to CsPbBr3 phase transition. This process facilitates the direct fabrication of highly emissive CsPbBr3/Cs4PbBr6 microstructure patterns inside Cs4PbBr6 SCs. Such a synergistic approach simplifies perovskite photolithography procedures and enables rapid, large-scale manufacturability. Furthermore, its integration with machine learning optimization algorithms showcases promising application potential in intelligent anti-counterfeiting. This novel approach, integrating perovskite SCs homologous substrate with customized photolithography, provides a new strategy for fabricating high-performance perovskite optoelectronic devices and is expected to promote technological advancement.

Solar energy, a clean and abundant resource, can be stored as latent heat in solid-solid phase change materials (SSPCMs) and subsequently utilized, offering great potential for advancing passive thermal management technologies such as thermal camouflage. Conventional SSPCMs often require active heating for high-temperature conditions, leading to additional energy consumption. Moreover, their permanent crosslinked structures limit reprocessability and increase environmental burden. Herein, we present a lizard-skin-inspired, solar-thermal-responsive, and reprocessable SSPCM (FTSPCM) featuring a dual crosslinked structure composed of dynamic phenol–carbamate bonds and Fe3+@Tannic acid (TA) coordination. Polyethylene glycol (PEG) functions as the phase change segment, while TA introduces both reversible covalent crosslinking and photothermal responsiveness. The FTSPCM exhibits a high latent heat of 102.9 J g−1, excellent shape stability, and maintains its thermal performance after three reprocessing cycles at 120 °C. The Fe3+@TA coordination network enables strong near-infrared absorption and efficient solar-thermal conversion, achieving a surface temperature of 62 °C and a conversion efficiency of 96.85% under 2 Suns irradiation. This dual-function design allows the material to achieve passive thermal camouflage via latent heat release at low temperatures and solar-assisted photothermal heating at high temperatures. This work presents a sustainable strategy for developing reprocessable, solar-responsive SSPCMs, showcasing the distinctive advantages of tannic acid-derived polyphenol chemistry in constructing passive thermal management systems for energy-efficient thermal camouflage and solar-driven thermal energy storage.

Metal covalent organic frameworks (MCOFs) are promising photocatalysts for carbon dioxide reduction reaction (CO2RR). However, the synthesis of ketimine-linked COFs remains challenging due to the low reactivity of ketones. Here, we report a straightforward strategy to construct diketimine-linked MCOFs via the condensation of acenaphthenequinone (Ace) with 1,3,6,8-tetra(4-aminophenyl)pyrene (TAPPy). The metal-free COF (TACOF-AA) exhibits AA stacking, while the addition of NiCl2·6H2O under identical conditions yields an AB-stacked Ni-based MCOF (Ni-TACOF-AB). The coordinated Ni species serve as active sites for CO2RR and enhance electron-hole separation. Photocatalytic tests demonstrate that Ni-TACOF-AB achieves a CO evolution rate of 11.71 mmol g−1 h−1 with 99.9% selectivity, which is 7.6 times higher than that of TACOF-AA. Density functional theory (DFT) calculations reveal that Ni-TACOF-AB lowers the activation energy barrier of the rate-determining step by regulating local charge distribution, facilitating electron transfer to adsorbed CO2. This work provides a novel approach for synthesizing ketimine-based COFs and highlights the importance of interlayer stacking in modulating photocatalytic performance.

Photocatalytic production of hydrogen peroxide (H2O2) via oxygen reduction reaction (ORR) and water oxidation reaction (WOR) from water and air offers a sustainable alternative to conventional anthraquinone processes. However, the intrinsic kinetic mismatch—fast ORR (microseconds to milliseconds) versus sluggish WOR (seconds)—limits overall efficiency. Here, we report aliphatic acylhydrazone covalent organic frameworks (AA-COFs) synthesized by coupling aliphatic hydrazides with benzotrithiophene motifs via acylhydrazone linkages. The pore walls are decorated with abundant S, O, and N heteroatoms, enhancing affinity toward both O2 and H2O, thereby improving the kinetics of both half-reactions. Through single-carbon atomic engineering, the optimized AA-COF achieves a trade-off between ORR and WOR kinetics, enabling efficient overall H2O2 photosynthesis from water and air without sacrificial agents. The material exhibits a H2O2 production rate of 4777 μmol g−1 h−1 and an O2 utilization/conversion efficiency of 99.3%. This work demonstrates that rational design of heteroatom-rich COFs can synchronize ORR and WOR, overcoming a major bottleneck in artificial photosynthesis.

Capacitive pressure sensors have garnered significant attention in electronic skin, human-machine interaction, health monitoring, and medical devices due to their remarkable properties like highly sensitive pressure perception, good repeatability, and rapid response capabilities. However, manufacturing capacitive pressure sensors that simultaneously achieve a broad linear detection range and high sensitivity remains a significant challenge. Herein, a novel hierarchically interlocked capacitive pressure sensor (HI-CPS) was designed by integrating a stretchable polyethylene glycol (PEG)-based nanofilm dielectric layer with hierarchically interlocked microstructures, demonstrating excellent linearity and high sensitivity over a wide sensing range. HI-CPS based on a one-layer nanofilm exhibits ultrahigh sensitivity (9.40 kPa−1) and an ultralow detection limit (0.1 Pa). When the dielectric layer comprises two layers of stacked nanofilms, the sensor not only maintains high sensitivity (3.17 kPa−1) but also achieves excellent linearity (R2 = 0.999) over a broad working range (<5 kPa), along with remarkable stability even after 10,000 cycles. Benefitting from the outstanding comprehensive performance, HI-CPS has been proven to be successfully implemented in monitoring various human biological signals, sign language recognition, and basketball shooting gesture correction. This strategy of assembling the tailored nanofilm with structural engineering has significant potential application in building high-performance pressure detection and recognition devices.

Open-pit coal mining causes severe soil nutrient depletion, limiting vegetation restoration. This study, conducted in the Baiyinhua No.2 mining area (Inner Mongolia), evaluated the effects of different fertilization strategies on soil nitrogen (N) and phosphorus (P) availability and microbial community responses. A field experiment was established in May 2023 with five treatments: low (L), medium (M), and high (H) phosphorus inorganic fertilizers, green manure (GM), and a microbial fertilizer (MF) containing nitrogen-fixing and rhizobia bacteria, compared to a control (CK). Results showed that MF significantly increased total carbon (TC) from 8.47 to 10.17 g·kg⁻¹ and total nitrogen (TN) from 0.37 to 0.56 g·kg⁻¹, while H significantly increased available phosphorus (AP) from 9.78 to 26.28 mg·kg⁻¹. Both treatments significantly altered fungal community structure, with increased relative abundances of Gibberella and Alternaria. The study concludes that MF and H improve soil nutrient availability by modulating fungal communities, with MF offering a sustainable biological approach for mine reclamation. These findings provide targeted fertilization strategies for restoring degraded mining soils and advancing green mining practices.

Calcium peroxide (CaO2) with a rich porous structure was synthesized via chemical precipitation for efficient fluoride removal from aqueous solutions. The adsorbent was characterized by SEM, BET, LPSA, and XRD, revealing a mesoporous material with a total pore volume of 0.51 cm3·g−1. Batch experiments investigated the effects of adsorbent dosage, initial fluoride concentration, reaction time, pH, and coexisting anions. Adsorption kinetics followed a fractal-like pseudo-first-order model, with intraparticle diffusion as the rate-limiting step. Equilibrium data were well described by the Sips isotherm, predicting a maximum adsorption capacity of 479.8 mg·g−1. Site energy distribution analysis indicated a normal distribution with an average energy of 13.36 kJ·mol−1. Mechanistic studies using FTIR and XPS revealed that fluoride removal proceeds via surface precipitation, ligand exchange, and electrostatic attraction. The high density of active sites contributes to the exceptional defluoridation performance, positioning CaO2 as a promising adsorbent for fluoride-contaminated water treatment.

Printing and dyeing sludge (PDS) fly ash is often classified as hazardous waste due to its high content and diversity of heavy metals (HMs). This study co-disposed PDS fly ash and heavy metal-contaminated soil to produce sintered ceramsites, investigating the effects of sintering conditions on physical properties and HM migration/transformation, and elucidating the immobilization mechanisms. The optimal sintering process was identified as preheating at 400 °C for 10 min, followed by sintering at 1150 °C for 10 min. The resulting ceramsites exhibited a 1-h water absorption of 2.7%, a bulk density of 830 kg/m³, HM volatilization rates below 15%, and a residual fraction (F4) proportion exceeding 86%. Characterization revealed that during sintering, HMs were encapsulated by the glassy phase and reacted with amorphous silica-alumina to form stable silico-aluminates, synergistically reducing HM mobility. However, sintering temperatures ≥1200 °C destabilized the ceramsite structure, causing secondary HM release. This research provides an efficient and simple route for the resource utilization of dyeing sludge fly ash and contaminated soil.

Liver fibrosis, a critical pathological consequence of chronic liver injury, remains a therapeutic challenge due to its complex mechanisms and limited effectiveness of conventional treatments. Recent advancements in two-dimensional (2D) nanomaterials, such as graphene derivatives, transition metal dichalcogenides (TMDs), black phosphorus nanosheets (BPNSs), MXenes, and layered double hydroxides (LDHs), have created novel opportunities for antifibrotic therapy. These materials exhibit exceptional physicochemical properties, including ultrahigh surface area, tunable surface chemistry, biocompatibility, and photothermal/electrochemical functionalities, enabling multifaceted interventions in fibrosis progression. The core therapeutic strategies mainly involve modulating hepatic stellate cells (HSCs) activation, inhibiting excessive extracellular matrix (ECM) deposition, and alleviating oxidative stress and inflammatory responses. However, 2D nanomaterials still face great challenges, such as long-term biosafety, precise functionalization for tissue-specific targeting, and scalable synthetic methods. This review systematically summarizes the recent breakthroughs in anti-fibrosis strategies based on 2D nanomaterials, elucidates their potential mechanisms of action, and explores the prospects for clinical translation of these nanoplatforms. Serving as a nexus between materials science and hepatology, 2D nanomaterials offer revolutionary prospects for precision medicine applications in hepatic fibrosis management.

Single-atom co-catalysts on semiconductor substrates offer a cost-efficient route to enhance photocatalytic performance with minimal precious metal loading. However, precise tuning of local coordination environments and construction of efficient single-atom co-catalysts remain challenging for overall water splitting. Here, we employ an icing-assisted photochemical reduction strategy to anchor atomically dispersed Pt species as hydrogen evolution co-catalysts on Al3+-doped SrTiO3 (Pt SA-STO). The optimized Pt SA-STO exhibits remarkable activity, with hydrogen and oxygen evolution rates of 13.62 and 6.71 mmol h−1 g−1, respectively, and a turnover frequency (TOF) of 2114.5 h−1. We pioneer the use of nuclear magnetic resonance (NMR) spectroscopy to quantitatively track the temporal evolution of Pt4+ to Pt2+ under continuous irradiation during the icing-assisted photoreduction. Advanced characterizations and theoretical calculations confirm that single-atom Pt co-catalysts facilitate directional transfer and extraction of photogenerated charge carriers, effectively suppressing surface recombination. This work provides insights into designing novel single-atom co-catalysts by deepening understanding of electronic configurations and active sites in photocatalytic overall water splitting.

Stimuli-responsive fluorescent hydrogels, owing to their tunable optical properties and unique smart response characteristics, have significant potential in encryption applications and information security. However, most current systems are limited to single-stimulus responsiveness and lack the capability for programmable information erasure or multi-modal dynamic synergy. Hence, we propose a multi-stimuli-responsive phase-change hydrogel incorporating aggregation-induced emission hydrophobic carbon dots (AIE-HCDs) and polyethylene glycol (PEG)-cellulose network, demonstrating dynamic fluorescence chromism under various external triggers. The hydrogel exhibits solvent-exchange-triggered fluorescence color changes from blue to red, enabled by the concentration modulation of AIE-HCDs through the exchange between PEG and water. Additionally, the temperature-induced phase transition of PEG from crystalline to molten state modulates the aggregation and dispersion of AIE-HCDs, thereby enabling dynamic fluorescence color changes. The phase transition further confers excellent shape-memory behavior and adjustable mechanical properties, with the tensile modulus varying from 6.28 MPa in the molten state to 36.23 MPa in the crystalline state, while maintaining high transparency (~88% in the molten state). By utilizing micro-contact printing and the multi-stimulus response, an encryption platform enables information to be hidden, selectively read under sequential stimuli (thermal, UV, and solvent), and completely erased upon demand. This strategy demonstrates significant potential for advancing high-level information encryption and anti-counterfeiting technologies.

This study systematically investigated the occurrence and vertical distribution of per- and polyfluoroalkyl substances (PFAS) in solid waste, leachate, and surrounding groundwater at a municipal solid waste landfill in Fuyang City, Anhui Province, China. A total of 23 PFAS were detected in solid waste, with total concentrations (∑PFAS) ranging from 7.95 to 172.28 ng·g⁻¹. Trifluoroacetic acid (TFA), an ultrashort-chain PFAS, was ubiquitous, contributing on average 59% to the total PFAS mass. PFAS composition varied with depth: long-chain PFAS dominated in middle and upper layers, while short-chain and ultrashort-chain PFAS were more abundant in deeper layers, indicating enhanced downward migration of shorter-chain compounds. Sulfonic acid PFAS exhibited increasing relative abundance with depth. Leachate ∑PFAS concentration was 14.35 μg·L⁻¹, dominated by short-chain compounds such as PFPrS and PFBS, consistent with the composition in bottom-layer waste. Groundwater surrounding the landfill contained multiple PFAS, with concentrations decreasing with distance from the landfill, confirming the landfill as a source of PFAS to the surrounding environment. Multivariate analyses (PCoA and Bray–Curtis dissimilarity) revealed that some groundwater samples closely resembled leachate in PFAS composition, suggesting direct impact via leachate migration. These findings underscore the role of landfills as significant reservoirs and sources of PFAS, particularly ultrashort-chain compounds, and highlight the need for improved leachate management to mitigate groundwater contamination.

MAB-phase-derived compounds exhibit promising electromagnetic wave (EMW) absorption properties due to their unique layered structure and desirable physicochemical characteristics. Among them, Cr2AlB2 is particularly attractive owing to its excellent thermal and electrical conductivity. However, conventional synthesis of Cr2AlB2 requires inert gas protection to prevent oxidation, significantly increasing production costs and limiting its application in EMW absorption. To overcome this bottleneck, we report the successful synthesis of high-purity Cr2AlB2 in ambient air using the molten salt shielded synthesis (MS3) method. This approach not only isolates the material from oxygen interference but also reduces the synthesis temperature, offering a cost-effective and scalable route. The as-synthesized Cr2AlB2 exhibits outstanding EMW absorption performance: a minimum reflection loss (RLmin) of -42.10 dB at 12.6 GHz and a maximum effective absorption bandwidth (EABmax) of 3.44 GHz at a thickness of 1.9 mm. This work not only facilitates the large-scale production of Cr2AlB2 but also provides critical insights into its practical application as a high-performance EMW absorber.

All-polymer solar cells (all-PSCs) are promising for flexible and wearable electronics due to their excellent stability and mechanical stretchability. However, achieving high performance remains challenging due to difficulties in controlling the morphology of polymer blend films. In this study, a novel polymer donor, PBDTF-DTP, incorporating a weak electron-withdrawing yet large-dipole-moment dithienylphthalimide (DTP-2T) unit, was rationally designed and synthesized for ternary all-PSCs. Introducing PBDTF-DTP as a guest donor enables complementary light absorption and deepens the highest occupied molecular orbital level, simultaneously improving short-circuit current density (J_SC) and open-circuit voltage (V_OC). The large dipole moment of DTP-2T increases the dielectric constant, suppressing non-radiative energy loss and further boosting V_OC. Notably, PBDTF-DTP exhibits a relatively higher molecular electrostatic potential than the host donor, effectively tuning compatibility with both polymer donor and acceptor, regulating blend morphology, and promoting formation of a nanoscale fibrillar network. This optimized morphology facilitates efficient charge generation and transport while suppressing charge recombination. Consequently, ternary all-PSCs based on PM6:PBDTF-DTP:PYIT achieve a synergistic enhancement in J_SC, V_OC, and fill factor, yielding a remarkable power conversion efficiency of 18.01%, significantly higher than that of binary PM6:PYIT devices (15.51%). This study demonstrates that combining electrostatic potential optimization with a ternary strategy provides an effective approach to regulate morphology and achieve high-efficiency all-PSCs.

Recovering gold from electronic waste (e-waste) is critical for sustainable resource management, yet conventional adsorbents suffer from poor acid stability and slow kinetics. Here, we report an acid-resistant cationic covalent organic framework (COF), TAPT-TNV, synthesized via irreversible Zincke reaction. TAPT-TNV exhibits exceptional stability in concentrated acids, retaining crystallinity and porosity after exposure to 12 M HCl and 6 M HNO3. The cationic skeleton, balanced by Cl− counterions, enables rapid and selective capture of AuCl4− through anion exchange, complemented by chemical reduction at triazine units. Adsorption kinetics are fast, reaching equilibrium within 30 minutes, with a maximum capacity of 1835.5 mg g−1 at pH 1. In real e-waste leachate, TAPT-TNV achieves a gold recovery rate of 99.42%, demonstrating high selectivity over competing metal ions. This work introduces a robust COF platform for precious metal recovery, addressing the limitations of hydrolytically unstable frameworks.

Aqueous aluminum-ion batteries (AAIBs) are promising for large-scale energy storage due to safety, sustainability, and theoretical high capacity. However, sluggish electron/ion transport in conventional cathodes limits rate capability. Here, we first propose high-entropy engineering of metal oxides (HEOs) as cathodes in AAIBs, leveraging the 'cocktail effect' and abundant electron transport pathways to enhance rate-capacity. Atomic-level interactions between different metal atoms broaden the d-band with reduced electronic level degeneracy, facilitating rapid electron transport, achieving one of the best rate capabilities (119.4 mAh g−1 at 10.0 A g−1) among metal-oxide cathodes. The disordered layered oxides formed with a high-entropy framework alleviate electrostatic repulsion between aluminum ions and the fixed lattice, mitigating structural degradation and imparting excellent cycling stability (over 95.1 mAh g−1 after 500 cycles at 2.0 A g−1). The optimized HEO-Cr cathode (Fe0.6Co0.6Ni0.6Mn0.6Cr0.6O4) exhibits outstanding rate performance and cycling stability. DFT simulations and electrochemical tests reveal that multi-transition metal incorporation, bandgap narrowing, and unique lattice structure drastically enhance electron transport efficiency. The layered phase formed after cycling, based on a high-entropy framework, overcomes challenges from high charge density aluminum ions, significantly enhancing cycling stability. This work paves the way for high-performance AAIBs and other aqueous multivalent metal ion batteries by rationally designing high-entropy engineering.

Fluorescence image-guided photodynamic therapy (PDT) enables real-time monitoring of photosensitizer biodistribution and metabolism for optimized treatment timing. However, its application remains limited by reliance on high-end imaging systems. To address this, we designed three novel small-molecule photosensitizers (TTNb, TTAn, TTPh) based on a 2-vinylbenzoic acid scaffold, functionalized at the 5-position with nitro, amino, or hydrogen groups. Replacing the nitro group with amino or hydrogen switched aggregation behavior from aggregation-induced emission (AIE) to aggregation-caused quenching (ACQ), accompanied by a red-to-green fluorescence shift and subcellular relocation from liposomes to lysosomes. These findings establish design principles for ratiometric nitroreductase probes and enable systematic comparison between AIE and ACQ photosensitizers. Among these, TTAn exhibited superior cellular uptake (2800 times higher than Ce6 in Eca-109 cells), specific lysosomal targeting, balanced reactive oxygen species (singlet oxygen/superoxide anion) generation, and intense fluorescence. Under white light irradiation, TTAn achieved an IC50 of 21 nM, surpassing Ce6 by 50-fold. Notably, TTAn produced strong fluorescence in mice tumors under both one- and two-photon excitation, detectable using conventional imaging tools (smartphones, DSLR cameras) or even visible to the naked eye, confirming outstanding tumor specificity. Leveraging these advantages, TTAn enabled successful image-guided two-photon PDT in Eca-109 tumor-bearing mice with a single treatment, demonstrating potent therapeutic efficacy and biosafety. This work provides a strategic blueprint for developing small-molecule theranostic agents that operate without complex fluorescence imaging systems.

Fiber-shaped zinc-air batteries (FZABs) with aqueous electrolytes combine intrinsic safety, high energy density (1086 Wh kg−1), and environmental compatibility, making them attractive for wearable applications. However, free water in the electrolyte induces severe anode degradation while being a critical reactant for cathode redox, presenting a dilemma between anode stability and cathode functionality. The semi-open structure of FZABs allows airborne water to permeate and migrate to the anode, causing interfacial instability, while high surface area accelerates solvent evaporation, leading to increased internal resistance and salt crystallization. Consequently, typical cycle life is limited to <50 h. To overcome these challenges, we report a polymer electrolyte that captures atmospheric water as a solvent through the semi-open structure, achieved by introducing acetamide (AA), identified via unsupervised clustering algorithms, into the poly(vinylidene fluoride-hexafluoropropylene)/zinc trifluoromethanesulfonate (PVDF-HFP/Zn(OTf)2) system. AA incorporation preserves solvent-retention capability while reconstructing the Zn2+ coordination structure, promoting salt dissociation and polymer-segment mobility. Low adsorption energy of AA on zinc surfaces suppresses parasitic reactions from ambient moisture, and preferential adsorption across zinc crystal planes directs Zn2+ deposition along the (002) face, leading to uniform plating morphology. The exogenous aqueous polymer electrolyte exhibits superior mechanical properties, enabling stable output even after compression by a 1.7-t vehicle. As proof-of-concept, FZABs integrated with fiber solar cells and sensors in clothing enabled real-time health monitoring and sustainable energy utilization, demonstrating promising practical applications.
