Deep-sea offshore wind energy is a strategic frontier for renewable energy, but operation and maintenance (O&M) costs exceed 20% of the total life-cycle cost, driven by harsh marine environments and remote locations. This review analyzes the development trends of offshore wind turbines: large capacity and commercialization, deep-sea and floating configurations, and intelligent automation. It synthesizes data acquisition methods and advanced analytics for offshore wind turbine monitoring, and summarizes the application status of digital technologies—artificial intelligence, big data, and digital twins—in O&M of critical components. The review highlights that floating offshore wind turbines, predominantly semi-submersible, are essential for deep-sea exploitation, yet their O&M remains labor-intensive and hazardous. Digital technologies enable predictive maintenance, fault diagnosis, and real-time monitoring, with demonstrated improvements in efficiency and cost reduction. Key challenges include data scarcity, model interpretability, and integration with existing infrastructure. Future research should focus on autonomous inspection, multi-source data fusion, and digital twin frameworks for floating wind turbines. The findings provide a theoretical and practical basis for reducing O&M costs and enhancing the competitiveness of deep-sea offshore wind power.

This study addresses the ambiguous carbon responsibility allocation and insufficient decarbonization incentives among multiple parks under carbon trading and green certificate mechanisms. A dual-game optimization method based on nodal carbon intensity (NCI) is proposed. First, a carbon intensity model with park energy subnets as nodes is established, and a carbon responsibility allocation method is derived. Second, a Stackelberg game model between integrated energy providers (IEPs) and load aggregators (LAs) within a single park is constructed, while a Nash bargaining model governs cooperation among multiple parks, forming a dual-game mechanism. The model is transformed using interval possibility degree conversion and Karush-Kuhn-Tucker (KKT) conditions, and an accelerated alternating direction method of multipliers (ADMM) algorithm is developed for solution. Case studies validate the correctness and effectiveness of the proposed model and improved algorithm. Results demonstrate precise carbon responsibility division, reduced carbon emissions across multiple parks, and enhanced overall benefits. The accelerated ADMM achieves convergence with combined residual satisfying c_k ≤ η^k c_0, where η is the acceleration factor, and restart iterations ensure monotonic residual reduction. The method effectively integrates demand-side influence in peer-to-peer trading, carbon-related economics, and accurate carbon responsibility allocation, providing a robust framework for low-carbon operation of multi-park integrated energy systems under carbon trading and green certificate mechanisms.

Real-time electromagnetic transient (EMT) simulation of DC-collector offshore wind farms is constrained by microsecond time steps, high model order from cascaded power electronic converters, and the inability of conventional decoupling methods to handle complex series-parallel topologies without introducing artificial delays. Existing non-delay decoupling methods, such as multi-area Thevenin equivalence (MATE) and compensation method, rely on branch tearing and are ill-suited for systems with numerous common-bus partitions, leading to excessive link variables and singular admittance matrices. This paper proposes a hierarchical hybrid non-delay decoupling parallel method that integrates MATE and its dual (node-tearing) approach through a layered architecture. The method constructs a mixed equivalent model tailored to DC-collector offshore wind farms, enabling flexible selection between unified and hierarchical solution modes for link variables based on operating conditions. A complete non-delay decoupling simulation workflow is established and validated on a DC series-parallel grid-connected offshore wind farm test case implemented in MATLAB. Results demonstrate that the proposed method reduces solution matrix dimensions and achieves significant speedup without compromising accuracy. For a 96-turbine wind farm, the hybrid decoupling model achieves an 11.99x speedup over the detailed model, compared to 8.77x for series-only decoupling and 6.22x for parallel-only decoupling. Mean absolute errors (MAE) for key variables remain below 0.1011, and root mean square errors (RMSE) below 0.6318, confirming high fidelity. The method enhances parallel simulation performance and offers a generalizable solution for real-time EMT simulation of large-scale offshore wind farms.

Overcoming the intrinsic loading ceiling of oxide-supported single-atom catalysts remains a long-standing challenge, because oxide frameworks generally provide limited capacity for accommodating high densities of isolated metal species. Here, we report a hollow TiO2 nanoreactor that effectively addresses the long-standing loading limitation of oxide-supported catalysts by coupling high-capacity ion exchange with structural confinement. The multiscale framework is derived from a sodium titanate hollow flower-sphere assembled from ultrathin nanosheets. It enables broad accessibility of exchange sites and facilitates high Cu uptake prior to oxide formation. Subsequently, during Ar-assisted transformation into oxygen-vacancy-rich TiO2, the incorporated Cu species remain highly dispersed within the framework, while vacancy-mediated metal–support interactions further enhance their stability. As a result, controllable Cu speciation is achieved at ultrahigh loadings of 7.4 wt% as spatially isolated single atoms and 12.4 wt% as single-atom/subnanometer-cluster hybrids. The optimized hybrid catalyst delivers a hydrogen evolution rate of 28.8 mmol g−1 h−1 under simulated sunlight, surpassing conventional low-loading Cu/TiO2 systems under comparable conditions. This strategy is readily extendable to other transition metals (Fe, Co, and Ni), establishing a structural design principle for constructing high-density and speciation-controlled metal sites on oxide supports.

Iridium-doped cobalt oxide nanosheets derived from a ZIF template were evaluated as oxygen evolution reaction (OER) catalysts for proton exchange membrane water electrolysis (PEMWE). Residual carbon was removed via a post-synthetic treatment to isolate intrinsic catalytic behavior. The Ir0.23Co0.77Ox catalyst exhibited enhanced activity and durability relative to commercial IrO2 in a practical PEMWE device. Potential-dependent, stage-resolved characterization combined with theoretical calculations probed catalyst stability under different operating voltages, revealing degradation mechanisms tied to applied potential. Contact angle measurements showed that the Ir0.23Co0.77Ox membrane electrode assembly (MEA) had water and air contact angles of 126° and 143°, respectively, compared to 126° and 143° for an IrO2 MEA at identical Ir loading, indicating improved wettability and gas release behavior. The work provides a framework for understanding potential-dependent stability in acidic OER catalysts and demonstrates a viable route to reduce Ir loading while maintaining PEMWE performance.

Multispectral camouflage materials must simultaneously address visible and infrared (IR) detection while maintaining environmental stability and mechanical flexibility for deployment in harsh conditions. This work presents a multilayer composite integrating a colorful, IR-transparent visible reflection (VR) layer, a low-emissivity graphene (LEG) layer, and an aramid nanofiber (ANF) aerogel layer. The VR layer provides tunable visible colors without compromising the low-emissivity property of the LEG layer, which achieves IR emissivity between 0.30 and 0.43. The ANF aerogel, reinforced with a grid structure, reduces thermal conduction, lowering IR radiation intensity by 40% at an 80 °C heat source. The composite exhibits effective electromagnetic interference (EMI) shielding and maintains multifunctional stability in strong acid, strong alkali, saline, and organic media. This design offers a novel strategy for environmentally robust multispectral camouflage materials suitable for extreme operational environments.

Lithium-sulfur batteries (LSBs) are recognized as a leading candidate for next-generation energy storage due to their high theoretical specific capacity (1675 mAh g⁻¹). However, the shuttle effect of lithium polysulfides (LiPSs) severely limits cycle life and energy efficiency. Here, we report a multi-interface engineering strategy employing a MnO₂-TiO₂@Ti₃C₂ MXene (MT@MX) heterojunction, synthesized via a facile redox reaction between MXene and KMnO₄, to modulate bidirectional polysulfide conversion. The 2D structure with high conductivity and abundant heterogeneous interfaces facilitates fast ion/electron transfer, reduces reaction energy barriers, and enhances adsorption via d-band center effects. The stepped built-in electric field (BIEF) in MT@MX lowers the migration energy barrier of LiPSs from catalytic MXene to TiO₂ and then to adsorptive MnO₂, enabling reversible migration across multi-interfaces. Optimized heterointerfaces synergistically integrate adsorption, diffusion, and catalytic conversion, yielding excellent cycling stability even at a high sulfur loading of 6.4 mg cm⁻². This work demonstrates that constructing heterojunctions with stepped BIEF offers a feasible approach to modulate interfacial diffusion and provides a new design strategy for high-performance LSB electrocatalysts.

Precise patterning of highly ordered organic semiconductor (OSC) thin-film arrays is critical for next-generation electronics. We report a ladder-like polysilsesquioxane (LPSQ) strategy to synthesize two functional analogs with tunable surface energies and robust dielectric properties. These LPSQ dielectrics, functionalized with alkyl or fluoroalkyl side chains, serve dual roles as gate insulators and patterning layers to guide blade-coating of 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT). This approach yields highly aligned arrays suitable for three-dimensional integration in flexible electronics. Synergistic combination of dense LPSQ dielectric packing and aligned semiconductor domains leads to excellent organic thin-film transistor (OTFT) performance, achieving approximately four-fold improvement in field-effect mobility compared to conventional silicon oxide dielectrics. Patterned LPSQ dielectrics enable high-resolution C8-BTBT patterning on plastic substrates, supporting 4-inch-scale 3D integration of flexible logic circuits, including inverters (voltage gain >100), NOR gates, and NAND gates. This work provides a scalable route to high-performance, large-area flexible organic circuits.

High-temperature X-ray imaging demands scintillators with high crystallinity, efficient scintillation, and robust thermal stability, yet suitable materials remain scarce. Here, we report an ultra-high-crystallinity transparent glass-ceramic (GC) scintillator strategically designed via controllable heat-treatment-induced crystallization. A sequential precipitation method is employed, where cubic CaF2 nanocrystals initially form, subsequently promoting heterogeneous nucleation and growth of hexagonal BaAl2Si2O8. Intrinsic nanoscale phase separation into F-rich and O-rich domains significantly reduces atomic diffusion distances, yielding an unprecedented crystallinity of up to 97.6%. Notably, defect traps (oxygen vacancy defects, likely located within the lattice or at crystalline/amorphous interfaces) enable efficient carrier capture and thermally stimulated release, contributing to remarkable resistance to thermal quenching. Consequently, the GC scintillator maintains 90.6% of its integrated X-ray excited luminescence (XEL) intensity at 300 °C, with the integrated XEL intensity reaching 94.2% of commercial Bi4Ge3O12 (BGO) at room temperature. This enables stable high-temperature X-ray imaging with a spatial resolution of ~10.4 lp mm−1 up to 225 °C. This work provides a versatile pathway for developing high-sensitivity scintillators for extreme-environment X-ray imaging.

Substrate interactions dictate the epitaxial growth of low-dimensional nanomaterials, yet controlling these interfaces at the atomic scale precision remains a critical challenge. Blue phosphorene (blueP) with freestanding lattice constant, experimentally realized exclusively on Ag(111), provides a unique platform to explore this interplay. Here, we elucidate the structural evolution of blueP on Ag(111), revealing that neighboring islands are not isolated but linked by single-phosphorus-atom bridges. To manipulate the interfacial coupling, we introduce a tellurium interlayer, driving the formation of an interfacial AgTe buffer that effectively decouples the islands. By tuning the substrate temperature, we achieve the synthesis of magic-number blueP clusters with uniform size and geometry. The resulting isolated blueP nanostructures facilitate the emergence of higher-order topological corner states in triangular geometries. Our findings demonstrate that tailoring interfacial interactions offers a robust route for reshaping phosphorene nanostructures, establishing essential building blocks for next-generation topological quantum materials.

Seawater electrolysis (SWE) is a reusable and convenient avenue for producing hydrogen, offering a promising solution to the energy crisis and global warming. However, poor electrolytic efficiency and irreversible corrosion caused by high concentrations of chlorine severely hinder the commercialization of SWE. To address these challenges, numerous strategies have been proposed in recent years, involving theoretical innovations, directional catalyst design, and electrolyser modification. This review provides a systematic summary of the chlorine-related challenges and solutions encountered in SWE. The chlorine-related theoretical knowledge and challenges in SWE systems are first emphasized. Subsequently, multiple anodic chloride suppression strategies are introduced from three aspects: directional regulation of oxygen evolution catalysts, optimization of electrolyte compositions, and ingenious upgrades of electrolytic cells. Finally, future challenges and development directions for large-scale application of SWE technology are explored. This review offers an in-depth analysis of the chlorine-related challenges encountered in the industrialization of SWE, aiming to accelerate the advancement of this technology toward practical applications.

Semiconductor-based surface-enhanced Raman scattering (SERS) substrates have attracted significant attention due to their high uniformity, reproducibility, stability, and cost-effectiveness. However, the Raman enhancement in semiconductors primarily relies on the chemical mechanism (CM), which typically results in a lower enhancement capability compared to traditional noble metals. In this study, we developed a novel two-dimensional (2D) SERS substrate, Ag2Te nanosheets (NSs), synthesized through a simple one-step redox reaction utilizing 2D Te NSs as the template. The 2D Ag2Te NSs not only exhibit strong interfacial interactions with molecules, thereby supporting the CM, but also possess quasi-metallic properties with low resistivity (2.8 × 10−4 Ω cm) and high density of free electrons (4.15 × 10^22 cm−3), giving rise to a significant visible-region surface plasmon resonance (SPR) band and contributing to enormous electromagnetic mechanism (EM). By synergizing CM and EM, the 2D Ag2Te NSs SERS substrate achieved an ultra-low limit of detection (LOD) of 10−10 M with an enhancement factor (EF) of 2.6 × 10^7 for methylene blue (MB), outperforming most semiconductors, even rivaling noble metals. The quasi-metallic properties of 2D Ag2Te NSs also benefit their sensitivity to multiple molecules. The accuracy and reliability were demonstrated in real-sample detections with recoveries of 91.5%–108.3% for various target molecules. These excellent performances, combined with remarkable cost-effectiveness, demonstrate the potential of 2D Ag2Te NSs as a practical SERS substrate with broad applicability. Furthermore, the inherent structural simplicity of these nanosheets creates significant opportunities for further sophisticated nanostructural engineering to advance the SERS performance in the future.

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.

The demand for high-performance scintillators in high-temperature applications, such as industrial flaw detection and oil exploration, necessitates materials with both high efficiency and thermal robustness. This work reports Tb3+-doped oxyfluoride glass scintillators exhibiting anti-thermal-quenching radioluminescence (RL). Three synergistic strategies were employed: (i) an oxyfluoride glass host providing a low-phonon-energy environment, (ii) increased structural densification of the glass network, and (iii) thermally enhanced energy transfer from Ce3+ to Tb3+. The resulting scintillators achieve an optical transmittance exceeding 88% at 542 nm, a record RL intensity of 350% relative to a standard Bi4Ge3O12 (BGO) crystal, and an imaging resolution of 24 lp mm−1. Notably, the RL intensity at 633 K reaches 143% of its room-temperature (303 K) value, demonstrating significant anti-thermal-quenching behavior. In contrast, commercial BGO and CsI:Tl scintillators exhibit RL intensities dropping to approximately 1% under identical conditions. These results establish the potential of Tb3+-doped glass scintillators for high-temperature X-ray imaging and provide a strategic framework for developing thermally robust scintillating materials.

Electrochemical CO2 reduction reaction (CO2RR) offers an attractive route to produce value-added multicarbon (C2+) products, yet suffers from competing hydrogen evolution and monocarbon production. Here, we propose a dual-confinement effect on CO2 reactant and *CO intermediate, induced by tuning the pore configuration of reconstructed covalent organic frameworks (RC-COFs). The highly crystalline microporous RC-COF-1, when coated on a Cu electrode, enhances local CO2 concentration and restricts CO diffusion, thereby promoting C-C coupling. In acidic electrolyte, the RC-COF-1@Cu electrode achieves a maximum C2+ Faradaic efficiency (FE) of 67.0% at 500 mA cm−2, while maintaining a total carbon product FE above 90% across a broad current density range (100–500 mA cm−2). Experimental and theoretical analyses confirm that the ordered micropores of RC-COF-1 modulate reactant adsorption and intermediate diffusion, leading to improved C2+ selectivity. This work underscores the critical role of COF pore architecture in microenvironment engineering for heterogeneous catalysis.

Metallic glasses (MGs) often suffer from sluggish hydrogen evolution reaction (HER) kinetics in neutral and alkaline media, with their catalytic performance predominantly confined to acidic environments. Herein, we reported a novel thermoplastic forming technique to fabricate a self-supported partially crystallized nanoporous Pt56.2Ni5.2Cu16.8P21.8 metallic glass (C-NPMG). The C-NPMG catalyst delivers ultralow overpotentials of 18.0 mV (0.5 M H2SO4), 42.2 mV (1 M KOH), and 88.0 mV (1 M phosphate-buffered saline (PBS)) at a current density of 10 mA cm−2, outperforming most state-of-the-art non-noble MGs and Pt-based benchmarks across all pH conditions. Notably, it maintains negligible performance decay for over 1000 h in alkaline electrolytes, showcasing superior stability. Experimental and computational analyses reveal that the enhanced HER activity arises from three synergistic effects: (1) the high-specific-surface-area nanoporous architecture that maximizes active site exposure; (2) the formation of crystallite-amorphous interfaces during partial crystallization, which lowers the energy barrier for H2 desorption; (3) the hierarchical super-hydrophilic and super-hydrophobic wettability of the C-NPMG, which optimizes mass transport and prevents electrolyte-induced corrosion. This work establishes a novel design paradigm for developing high-performance, pH-universal HER electrocatalysts by integrating structural nano-engineering and crystallite-amorphous phase synergy in metallic glass systems to overcome the trade-offs between performance and stability in electrochemical water splitting.

Biodegradable metals (BMs) are designed to corrode gradually in physiological environments, yet this corrosion can compromise their mechanical integrity, potentially causing premature implant failure. For emerging zinc-based alloys, the corrosion-mechanical property relationship remains inadequately characterized. This study systematically investigated the long-term corrosion-associated mechanical behavior of hot-extruded Zn-Cu and Zn-Cu-Fe alloys, promising Zn-based bio-metals, in comparison with pure Zn, under immersion degradation in Hank's solution. Electrochemical impedance spectroscopy and mechanical testing revealed that the evolving corrosion profile governs mechanical performance. Alloying with Cu and Fe mitigated corrosion's detrimental effects: grain refinement reduced localized corrosion susceptibility, while finely dispersed second phases acted as cathodic sites, promoting uniform corrosion. Additionally, Cu and Fe facilitated the formation of protective corrosion product layers, suppressing further matrix attack. Consequently, the overall reduced corrosion, particularly localized corrosion, lowered stress concentration susceptibility, delaying mechanical decline and preserving structural integrity. These findings elucidate the degradation-mechanical property correlation in Zn-based bio-metals and underscore critical considerations for developing new bio-metals for clinical translation.

Intramolecular through-space charge-transfer (TSCT)-enabled thermally activated delayed fluorescence (TADF) emitters have shown exceptional potential for advancing organic light-emitting diode (OLED) technologies, owing to their efficient utilization of triplet excitons and optimized photophysical properties. To date, the intrinsic correlation among molecular geometries, intramolecular non-covalent interactions, and photophysical properties in TSCT-TADF emitters remains unconfirmed, and this study theoretically clarifies this critical correlation. Specifically, through integrating molecular engineering, screening strategies, first-principles calculations, energy decomposition analysis, and statistical modeling, we systematically investigated 24 experimentally reported TADF molecules, and 54 newly designed structures in both solution and thin-film environments. We establish a clear geometric criterion for high-efficiency TSCT-TADF emitters: donor-acceptor (D-A) dihedral angles below 25° and interfragment distances within 4 Å—conditions validated by both theoretical predictions and experimental evidence. Based on this insight, we designed two novel molecular libraries with benzene- or carbazole-derivative bridges, using O-bridged triphenylamine (DPXZ) as the donor and quinolino[3,2,1-de]acridine-5,9-dione (QAO) as the acceptor. Our calculations confirm that sub-25° D-A dihedral angles correlate with exceptional delayed fluorescence efficiency, with predictions reaching up to 96% and an average of 70% for the new thin film systems. This study provides a rational design strategy for high-performance TSCT-TADF emitters, significantly advancing the molecular-level understanding of through-space interactions and accelerating the discovery of tailored, efficient OLED materials.

Accurate accounting of county-level carbon budgets and their spatio-temporal evolution is essential for formulating low-carbon development strategies tailored to each division and achieving carbon peak and neutrality goals. This study constructed a comprehensive, accurate, and unified model to measure terrestrial ecosystem carbon absorption, anthropogenic carbon emissions, and net carbon budget from 2010 to 2020 across the Xinjiang Production and Construction Corps and its divisions. Results indicate: (1) Terrestrial ecosystems consistently acted as net carbon sinks, but total carbon absorption declined slowly, with carbon sequestration capacity persistently decreasing. Cultivated land, the sole carbon source, expanded rapidly into forests and grasslands. Anthropogenic carbon emissions rose steadily, with growth rates sharply decelerating after 2015, exhibiting a spatial pattern of "high in the north and east, low in the south and west." (2) Total carbon emissions/absorptions increased rapidly from 2010 to 2015, then slowed from 2015 to 2020. Energy consumption dominated, contributing over 95% of emissions in each division and 99% regionally. High-emission zones expanded eastward from the 8th Division in the Junggar Basin; by 2020, the 8th, 13th, and 6th Divisions, occupying 26.52% of the land area, carried 78.16% of net carbon emissions, marking them as high-density emission zones. (3) Carbon balance zoning in 2020 identified one carbon sink functional zone, nine low-carbon maintenance zones, and three high-carbon optimization zones, the latter concentrated in a strip in the central-eastern region covering 26.52% of the area.

The proliferation of lithium-ion batteries (LIBs) in portable electronics and electric vehicles has generated a pressing need for sustainable recycling of spent batteries. Conventional pyrometallurgical and hydrometallurgical routes suffer from low metal recovery efficiencies or require additional precipitants. This study introduces a clean and efficient process for recovering lithium (Li) and cobalt (Co) from spent LiCoO2 cathode materials using a choline chloride-oxalic acid-water (ChCl-OA-H2O) deep eutectic solvent (DES). The method exploits selective precipitation of Co as cobalt oxalate dihydrate (CoC2O4·2H2O) followed by water-content-regulated recovery of Li as lithium oxalate (Li2C2O4) via evaporation crystallization, eliminating the need for external precipitants. Under optimized conditions (molar ratio 1:1:8, solid-liquid ratio 100 g/L, 90 °C, 6.5 h), the leaching efficiency of Li reached 99.4%, with recovery efficiencies of 88.3% for Li and 97.8% for Co. The DES system demonstrated robust cycling stability, maintaining Li and Co recoveries of 78.1% and 92.8% after six regeneration cycles. This work provides a low-pollution, economically viable pathway for LIB recycling, contributing to resource sustainability and offering significant industrial potential.

Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic persistent organic pollutants that pose significant risks to human health. Owing to their high binding affinity for proteins, PFAS are ubiquitously detected in human populations worldwide. Following oral ingestion, PFAS bind to transport proteins such as human serum albumin and organic anion transporters, facilitating their distribution and accumulation in various tissues and organs, including the liver and kidneys, and enabling penetration across the blood-brain and placental barriers. This review systematically examines the migration and enrichment behaviors of PFAS in human tissues and organs mediated by multiple transport proteins, the molecular mechanisms underlying PFAS-protein interactions, and the key factors influencing these interactions. Additionally, we discuss the potential applications derived from PFAS-protein binding. By synthesizing current research findings, this review provides a theoretical foundation for future investigations into PFAS-protein interactions and outlines prospective research directions. The pervasive environmental contamination and documented health effects, including developmental retardation, endocrine disruption, obesity, and cancer, underscore the urgency of understanding PFAS toxicokinetics. Our analysis highlights the critical role of protein binding in the prolonged biological half-lives of PFAS and their tissue-specific accumulation, which are central to health risk assessment and the development of mitigation strategies.

Developing plasmonic nanomaterials with compositions beyond noble metals is crucial for expanding their applications. Transition metal nitrides, such as titanium nitride (TiN), exhibit excellent plasmonic optical properties and photothermal conversion efficiency, showing promise in catalysis, photothermal therapy, and seawater desalination. However, the structure-property relationship governing their plasmonic optical properties remains unclear. Here, we constructed Au@TiN core-shell nanostructures and systematically investigated the tunability of their geometry, composition, and optical properties. By varying the Au core size and TiN shell thickness, we achieved precise control over the localized surface plasmon resonance (LSPR) from visible to near-infrared wavelengths. Single-particle scattering spectroscopy revealed distinct plasmon hybridization modes, with experimental spectra matching theoretical simulations. The Au@TiN nanostructures exhibited enhanced photothermal conversion efficiency (η = 78.5%) under 808 nm laser irradiation, significantly outperforming pure TiN nanoparticles (η = 45.2%). This work demonstrates multi-factor control over plasmonic effects in TiN, providing insights for designing TiN-based plasmonic nanomaterials for catalysis and sensing.

High-quality β-Ga2O3 membranes are pivotal for fabricating high-performance memristive devices. Here, vertical Ag/β-Ga2O3/Pt memristors built on high-crystalline-quality β-Ga2O3 membranes via lattice epitaxy engineering and a sacrificial-layer-assisted exfoliation strategy are reported. The resulting β-Ga2O3-based device demonstrates a high ON/OFF ratio exceeding 10^8, low SET/RESET voltages of 0.13 V/−0.11 V, low programming current of 10^-10 A, stable data retention beyond 4 × 10^4 s, and excellent subthreshold characteristics of ~0.47 mV/dec. Adjustable compliance current enables the coexistence of volatile and non-volatile switching modes. Additionally, the resistive switching versatility is predominantly governed by the migration of Ag ions, as supported by electrical characterizations and first-principles calculations. Furthermore, a β-Ga2O3 memristor-based circuit that functions as a reconfigurable and non-volatile exclusive OR (XOR) logic gate has been designed and simulated, enabling both image encryption/decryption and edge detection. This work not only demonstrates lattice-engineered, high-quality β-Ga2O3 membranes for fabricating advanced memristors but also extends their applicability to digital logic and reconfigurable image processing.

The Qingling River, a representative silicate rock catchment in the upper Yangtze Basin, is vital for agricultural productivity in central Yunnan. To investigate its hydrochemical characteristics, river water samples were systematically collected during both dry and wet seasons. Employing hydrochemical diagrams, statistical analysis, and absolute principal component score-multiple linear regression (APCS-MLR) modeling, we identified influencing factors and their contributions to water chemistry and evaluated irrigation suitability. Results showed that pH ranged from 7.36 to 9.18 in dry season and 7.12 to 8.92 in wet season, with total dissolved solids (TDS) varying between 119–2684 mg·L−1 and 125–2342 mg·L−1, respectively. Dominant cations were Ca2+ and Na+, while anions were primarily SO4^2− and HCO3^− in both seasons; notably, SO4^2− concentrations significantly exceeded the Yangtze River Basin’s average. Hydrochemical types varied seasonally: HCO3·SO4-Ca·Mg and HCO3·SO4-Ca dominated in dry season, whereas HCO3·SO4-Ca·Na, HCO3·SO4-Ca·Mg, and HCO3-Ca prevailed in wet season. The river water was affected by five factors: sulfuric acid-dominated water-rock interactions, carbonic acid-dominated water-rock interactions, domestic sewage discharge, agricultural non-point source pollution, and unknown sources. Contribution rates were 47.90%, 24.80%, 16.98%, 2.40%, and 7.92% in dry season, and 28.23%, 28.94%, 27.48%, 2.02%, and 13.34% in wet season, respectively. Water-rock interactions emerged as the primary control on hydrochemistry. While most samples were suitable for irrigation, a few exhibited high salinity, warranting cautious use.

This work presents a cracked template and vacuum metal evaporation strategy for fabricating structurally randomized copper (Cu) mesh films. Regulating the internal stress distribution within the coating during template cracking enables controlled fabrication of Cu mesh films with varying discrete degrees of mesh aperture area and distinct probability distributions of metal line inclination. The influence of structural parameter randomization on properties was systematically investigated, encompassing higher-order diffraction energy homogenization, optoelectronic performance, and electromagnetic interference shielding effectiveness (EMI SE). Results demonstrate that increasing structural randomization effectively suppresses higher-order diffraction energy, achieving a reduction to −3.93 dB in normalized higher-order diffraction energy. Furthermore, the Cu mesh film exhibited minimal degradation on imaging system performance, with resolution decreasing only marginally from 80.6 to 71.8 lp/mm. Simultaneously, the most randomized Cu mesh film demonstrates an ultra-low sheet resistance (3.31 Ω/sq), high visible light transmittance (88.7% at 550 nm), an exceptional figure of merit (FoM=913.69), and robust EMI SE within the X-band (average SE of 33.18 dB). These findings underscore that metal mesh films incorporating structural randomization offer an effective strategy for enhancing EMI shielding in high-performance optoelectronic imaging systems.

A novel slag-based carbon powder-sodium alginate composite membrane was fabricated by incorporating purified slag-derived carbon powder into a sodium alginate matrix, followed by dual crosslinking with polyethyleneimine and glutaraldehyde. The membrane was designed to achieve waste-to-treat-waste objectives, enhance the resource value of industrial slag, and provide an efficient, regenerable adsorbent for Cr(VI) removal from water. Adsorption performance was systematically evaluated. Optimal adsorption occurred at pH 2, with elevated temperature and initial Cr(VI) concentration favoring uptake; equilibrium was reached at approximately 73 h. The adsorption kinetics followed a pseudo-second-order model, and isotherm data fitted the Langmuir model, yielding a theoretical maximum adsorption capacity of 471.970 mg·g−1. Thermodynamic analysis indicated a spontaneous, endothermic process. In simulated wastewater containing multiple metal ions, competitive effects moderately reduced adsorption capacity. After three adsorption-desorption cycles, the membrane retained good structural stability despite a decline in capacity. Characterization via SEM-EDS, FTIR, and XPS revealed a porous structure and the involvement of functional groups such as –COOH and –NH2, with partial reduction of Cr(VI) to Cr(III). The adsorption mechanism was attributed to synergistic electrostatic interaction, chemical coordination, and redox reactions.

Sintering ash washing wastewater from steel plants is characterized by high salinity, high chloride content, high thallium load, and coexistence of multiple metals, posing significant treatment challenges. This study employed thermodynamic simulation to elucidate the speciation and transformation of thallium in such wastewater, and systematically investigated a combined process of sulfide precipitation coupled with coagulation-flocculation. The results showed that at pH 9–10, thallium predominantly existed as Tl+. Under oxidizing conditions, the stable complex anion [TlCl4]− dominated at pH < 8.1, while at pH > 8.1, a mixed system of solid Tl2O3 and dissolved TlClO3 coexisted. Under optimized conditions (pH 12, 2.0% thallium removal agent, 1.0% multi-effect auxiliary agent), the thallium concentration in the wastewater decreased from an initial 9.58 mg·L−1 to 4.31 μg·L−1, meeting the stringent discharge limit of ≤5 μg·L−1. Concurrent removal of Cu, Zn, and Cd was achieved. The primary removal mechanism was sulfide precipitation, with lattice substitution between Tl+ and K+ serving as an auxiliary pathway. This study provides a practicable technical route for advanced treatment of high-chloride, high-thallium industrial wastewater.

Biochar and microbial inoculants are widely used for agricultural soil amendment. To investigate the effects of different straw biochars and Bacillus subtilis inoculant, applied individually or combined, on nitrogen transformation in dryland soil, a 60-day laboratory incubation experiment was conducted with six treatments: control (CK), 4% rice straw biochar (S), 4% rapeseed straw biochar (Y), 4% rice straw biochar plus 5 mg/kg inoculant (SJ), 4% rapeseed straw biochar plus 5 mg/kg inoculant (YJ), and inoculant alone (J). Results showed that rice straw biochar significantly increased soil nitrate nitrogen content by 148.74%–152.68% compared to CK, enhancing nitrification. Combined application with inoculant further increased average net nitrogen mineralization rate by 77.28%–99.38%. Conversely, rapeseed straw biochar decreased nitrate nitrogen by 51.66%–57.61%, and combined application reduced net nitrogen mineralization rate by 82.07%–84.73%. Treatments S, Y, SJ, and YJ promoted microbial biomass nitrogen (MBN) synthesis, with S and Y increasing MBN by 2.02- and 2.20-fold over CK, respectively. Combined treatments further increased MBN by 103.26%–149.44% relative to single biochar treatments. These findings indicate that biochar type governs nitrification and net nitrogen mineralization, while combined application exerts synergistic effects on MBN. For comprehensive dryland soil improvement, YJ treatment is optimal, reducing inorganic nitrogen loss risk and enhancing microbial nitrogen activity.

Electrocatalytic CO2 reduction reaction (CO2RR) to formate offers a promising pathway for storing renewable electricity in chemical fuels and enabling carbon recycling. The development of efficient and stable catalysts for this specific pathway, however, remains a central challenge. Heteroatom doping can significantly tune the interaction between active sites and key intermediates, boosting catalytic performance. Conventional doping in Bi-based catalysts often relies on uncontrollable in-situ electrochemical processes, leading to ineffective bulk incorporation. Here, we present a simple pre-doping strategy that enables precise doping at surface active sites, thereby enhancing electrochemical performance. The resulting catalyst achieves >95% Faradaic efficiency for formate across 100–500 mA cm−2 in a flow cell and maintains >95% efficiency for over 70 h at 100 mA cm−2 in a membrane electrode assembly, outperforming pure Bi and Bi2S3. A solar-driven system further demonstrates a 4.4% solar-to-formate conversion efficiency. Mechanistic studies reveal that sulfur doping increases electron density, stabilizes the key *OCHO intermediate, and suppresses hydrogen evolution. These findings provide valuable insights into the precise pre-doping modulation of surface active sites for designing highly efficient and stable CO2RR catalysts.

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.

Efficient sequestration of radioactive iodine species (I2, CH3I, I3−) is vital for nuclear safety and environmental protection. However, developing multifunctional adsorbents that remain effective under diverse conditions remains a significant challenge. Herein, we report two functionalized PD-COFs (PD-WS and PD-WY) with moderate crystallinity, outstanding thermal stability, and robust chemical resistance. They exhibit superior adsorption performance in both gas and liquid phases. Specifically, at 75°C, PD-WY achieves capacities of 4.88 g g−1 for I2, 1.55 g g−1 for CH3I, and 5.55 g g−1 for the I2/CH3I mixture, while high capacities are also retained at room temperature. In solution, PD-WY adsorbs up to 3.56 g g−1 of I3− in water and 2.00 g g−1 of iodine in cyclohexane. These COFs display rapid kinetics (K80% = 3.25 g g−1 h−1 for I2 and 7.89 g g−1 h−1 for I3−) and excellent selectivity. Mechanistic studies indicated that the excellent iodine affinity of PD-COFs arises from their rich electronic structures, abundant active sites, and charge transfer interactions. These findings position PD-COFs as highly promising adsorbents for nuclear waste treatment and environmental remediation.

Reducing dependency on external energy sources for gait recognition systems in legged robots is critical for extending operational endurance in field transport and emergency rescue. This study presents a performance-enhanced triboelectric sensor with a tilted magnetic microneedle surface (TMMS-TENG), inspired by the tilted microstructures on mantis forelimbs. By integrating magnetorheological materials with micro-engineering, the tilting and bending of microneedles are controlled via magnetic field direction and intensity, significantly modulating the sensing signal. The TMMS-TENG achieves a peak output power of 5.82 mW at a load resistance of 3 MΩ, with high sensitivity (7.57 kPa⁻¹ in the 0–1 kPa range, 3.55 times higher than planar structures), fast response (loading: 61.3 ms; recovery: 50.8 ms), and high stability. When the microneedle tilt angle is 25°, sensitivity remains at 1.19 kPa⁻¹ in the 1–11 kPa range. The sensor demonstrates outstanding recognition capability and stability in legged robot gait recognition, offering potential for robotics, intelligent manufacturing, and health monitoring. This approach reduces reliance on external power, enhancing flexibility and energy efficiency in field operations.

Flexible photodetector arrays are critical for artificial retina prosthetics, yet their performance is limited by electrode discontinuities and incomplete perovskite crystallization under mechanical stress. This study introduces a funnel-shaped precursor engineering strategy to fabricate high-performance flexible perovskite photodetectors. An ultrathin platinum electrode film (UTPF) of less than 10 nm thickness is deposited via radio frequency magnetron sputtering combined with angular ion beam polishing, achieving an ultra-smooth surface. A vapor deposition method with dynamically regulated evaporation rates produces a dense-gradient PbI2 precursor with a funnel-shaped vertical structure, facilitating CH3NH3I solution penetration and yielding a dense, uniform perovskite film with large grains and strong interfacial bonding to the UTPF. The resulting devices exhibit a high detectivity of 19.48×10^12 Jones, an on/off current ratio of 6.87×10^4, and retain 92.53% of the original photocurrent after 4000 bending cycles at large angles. Integrated 10×10 flexible photodetector arrays demonstrate uniform dark current and photocurrent, along with high imaging resolution, confirming reliable imaging capabilities. This work addresses the mechanical and crystallization bottlenecks of flexible perovskite photodetectors, offering a viable route for artificial retina and wearable optoelectronic applications.

Femtosecond laser irradiation enables spatially resolved printing of CsPbBr3 perovskite quantum dots (PeQDs) within borosilicate glass, yet the write-erase-recovery cycle is governed by glass network connectivity, a parameter that remains poorly quantified. This work demonstrates that lanthanide oxide doping (Ln2O3, Ln = La, Gd, Lu) modulates the silicon-oxygen network and controls in situ PeQD formation. Optimal Ln2O3 concentration disrupts bridging oxygen (Si-O) bonds, yielding a looser network that lowers the crystallization barrier and permits complete laser erasure. Over-doping induces a rigid network that prevents erasure. Erased regions autonomously regenerate via water molecule invasion, with recovery time dictated by lanthanide type and concentration. At 2 mol% Lu2O3, the Si-O tensile vibration at 1039 cm-1 exhibits maximal frequency and intensity reduction, correlating with the shortest self-recovery time in air. The reversible luminescence survives multiple cycles without degradation, enabling 4x6 code arrays and Quick Response codes that are invisible under daylight, decodable under UV, and selectively erasable by low-power fs laser for anti-counterfeiting. This mechanism offers a viable route for critical information encryption and decryption.

Muscle contraction generates both biomechanical force myography (FMG) and bioelectrical electromyogram (EMG) signals, yet simultaneous acquisition remains challenging due to disparate sensing modalities and interface stability issues. This work presents a four-layered all-fibrous multimodal sensor patch (FMSP) integrating a micro-hump structured pressure sensor and an adhesive electrophysiological electrode. The pressure sensor achieves a sensitivity of 148.1 kPa⁻¹ over a broad range of 0.054–200 kPa, while the electrode maintains a skin adhesion strength of 67.6 kPa, ensuring low interface impedance and a signal-to-noise ratio (SNR) of 21.8 dB for EMG, surpassing commercial gel electrodes. The FMSP enables synchronous monitoring of FMG and EMG during arm movements, discriminating bending angles and lifted weights. This platform addresses the bottleneck of single-modality muscle assessment, offering a dual-signal strategy for muscle fatigue detection and human-machine interfaces. The all-fibrous architecture, leveraging silk fibroin and conductive materials, provides a scalable route for wearable physiological monitoring with enhanced signal fidelity and user comfort.

Viral capsids exemplify icosahedral polyhedral architectures formed via spontaneous self-assembly of identical protein subunits through non-covalent interactions governed by symmetry-matching rules. Mimicking this biological strategy, hydrogen-bond-directed supramolecular polyhedra have emerged as a focal point in supramolecular chemistry, offering dynamic responsiveness, reversible assembly, and structural designability. However, these systems face persistent challenges in structural stability and geometric precision control, particularly under competitive solvent conditions and thermal stress. This review systematically categorizes hydrogen-bonded supramolecular polyhedra by structural type and building block characteristics, including calix[4]resorcinarene cavitands, resorcin[4]arenes, pyrogallol[4]arenes, and peptidic containers. Key experimental milestones are highlighted: encapsulation-induced stabilization of heterocapsules (Chem Eur J, 2013, 19: 3685–3692), guest rotation within self-assembled heterocapsules (Proc Natl Acad Sci USA, 2009, 106: 10444–10448), and mechanochemical encapsulation of fullerenes in peptidic containers via dynamic chiral self-sorting (Chem Eur J, 2016, 22: 3148–3152). These constructs demonstrate tunable capsule spaces through hydrogen-bonding linkers (J Org Chem, 2006, 71: 8800–8806) and hybrid hydrogen-bonded/metal-ligand coordination capsules with dual guest-exchange control (Chem – An Asian J, 2014, 9: 1076–1082). The review identifies critical scientific bottlenecks—including solvent-dependent disassembly, limited cavity size, and trade-offs between reversibility and mechanical robustness—and outlines future trends toward precision functionalization. Establishing a theoretical framework for controlled assembly, this work provides methodological guidance for advancing bioinspired hydrogen-bonded polyhedral structures in synthetic chemistry and materials science.

Supramolecular materials exhibiting reversible circularly polarized luminescence (CPL) are of great interest for their potential applications in the development of 3D display technology and information encryption. In this work, we synthesize a pair of molecular cage enantiomers constructed from (2R)/(2S)-diaminocyclohexane-functionalized naphthalenediimide units ((4R/S)Cy-NDIDA) and fluorescent tris(4-formylphenyl)amine (TPA) components. The cage exhibits extremely weak fluorescence emission in both liquid and solid states. Notably, the introduction of tris(pentafluorophenyl)borane (TFPB) as a guest molecule gradually activates the photoluminescence (PL) and CPL signals of the chiral cage via host-guest interaction. Furthermore, photochromic diarylethene (DAE) is incorporated into the system. The reversible isomerization of DAE under light irradiation enables dynamic control of Förster resonance energy transfer (FRET) interactions with the host-guest complex, resulting in switchable fluorescence quenching and recovery. This precise strategy for controlling dynamic CPL switching of the chiral molecular cage offers a novel strategy for the development of supramolecular CPL systems.

The escalating demand for lithium, driven by electric vehicles and renewable energy storage, necessitates efficient extraction from salt-lake brines where high Mg2+/Li+ ratios and similar physicochemical properties of Li+ and Mg2+ pose a technical bottleneck. Conventional precipitation and solvent extraction are inefficient and energy-intensive. Electrodialysis (ED) offers lower energy consumption but is limited by the selectivity of ion exchange membranes. This study introduces acid-base pairs within a polybenzimidazole matrix via controlled sulfonation to enhance Li+/Mg2+ selectivity. The optimal SP45 membrane, with a sulfonation degree of 45%, forms a cross-linked structure with contracted ionic clusters and discrete hydrophilic domains, imposing higher energy barriers for Mg2+ transport. The SP45 membrane achieves a perm-selectivity of 48.1 at 2 mA cm−2, with less than 10% selectivity degradation over multiple cycles in mixed-salt systems. In a 4-stage ion-distillation device, a separation factor exceeding 60,000 between Li+ and Mg2+ is attained. This work provides fundamental insights into ion transport regulation through molecular-level acid-base pairs engineering, offering a pathway for advanced ion-selective separation membranes.

Quantum dot (QD)-based memristors enable precise and energy-efficient neuromorphic computing through atomic-level control over electrical synapse performance. However, the stochastic nature of QD structures results in poor reliability of resistive switching, limiting practical applications. This work presents a data-driven QD synthesis optimization loop that integrates high-throughput density functional theory with machine learning to establish a cross-scale screening platform for precise QD synthesis. By minimizing structural disorder through pure phase, uniform size distribution, and highly preferred orientation, QD-based memristors demonstrate a 57% reduction in switching voltage, a two-order-of-magnitude increase in ON/OFF ratio, and endurance and retention degradation as low as 0.1% over 8.4 × 10^7 s of continuous operation and 10^5 rapid read cycles. The dynamic learning range and neuromorphic computing accuracy improve by 477% and 27.8% (reaching 92.23%), respectively. These findings establish a scalable, data-driven strategy for rational design of QD-based memristors, advancing next-generation reliable neuromorphic computing systems.
