Eight major components significantly attracted the tea green leafhoppers, Empoasca flavescens F. Based on their relative abundances, following synthetic blends were made for field experiments: 1) eight-component-attractant blend included Z-3-hexen-1-ol, Z-3-hexenyl acetate, Z-ocimene, Me SA, Z-3-hexenyl butyrate, dodecane, hexadecane and nonanal at 10, 10, 1, 11, 2, 6, 2 and 4 mg mL^-1 in n-hexane, respectively;2) four-component-attractant blend #1 contained hexadecane, Z-3-hexenyl acetate, Z-3-hexen-1-ol and nonanal at 2, 10, 10 and 4 mg mL^-1 in n-hexane, respectively;3) four-component-attractant blend #2 contained hexadecane, Z-3-hexenyl acetate, Z-3-hexen-1-ol and Me SA at 2, 10, 10 and 11 mg mL^-1 in n-hexane, respectively. Thymol and 1-methoxy-4-methyl-2-(1-methylethyl)-benzene, identified from Lavandula angustifolia aeration samples, significantly repelled the leafhopper as strong repellents when tested alone or in combination at 10 mg mL^-1. For field bioassays, each attractant lure was attached to a bud green sticky board hung from a bamboo stick at above tea plant level for catching the leafhoppers, whereas the repellent dispenser was tied to a tea branch inside tea clump for pushing the leafhoppers away from tea clumps. The results showed that the eight-component-attractant blend caught similar numbers of the leafhopper as did the four-component-attractant blend #1 at about 53–79 leafhoppersrap/day, which were significantly higher than those on the hexane-control bud green sticky boards. Average leafhopper catches from un-baited sticky boards were about 51–73 leafhoppersrap/day when pushed by the repellents placed inside tea plants, with the two-component-repellent blend being more effective than their single components. When the two-component-repellent blend was further tested with the three attractant blends in a push-pull fashion, average trap catches ranged from 62 to 92 leafhoppersrap/day. Control efficacy on the leafhoppers within the push-pull zones increased progressively from day 1(43%) to day 5(73%). This push-pull approach might have a great potential as a green control strategy for combating the tea green leafhoppers. 展开更多

The efficient separation of lutetium(Lu)and ytterbium(Yb)re mains a significant challenge in rare earth elements processing due to their nearly identical chemical properties.In this work,a"push-pull"synergistic extraction system was developed,utilizing a mixture of phosphate ester extractants(named HP350)as the extractant and diethylenetriamine-N,N,N',N",N"-pentaacetic acid(DTPA)as the watersoluble complexing agent,aiming to achieve a higher selective separation of Lu3+and Yb3+.The effects of HP350 and DTPA concentrations,the equilibrium pH of the aqueous phase,and the extraction equilibration time on the separation performance of Lu3+/Yb3+ were systematically investigated.Notably,under the optimal conditions,the separation factor of Lu/Yb(SFLu/Yb)in the HP350-DTPA"push-pull"extraction system reaches 2.58±0.08,compared to only 1.81 with HP350 extractant alone.This result also greatly exceeds most of the extractants reported so far.Besides,the thermodynamic modeling results provide additional evidence that the presence of DTPA in the aqueous phase enhances the SFLu/Yb.The stripping experiment demonstrates that the SFLu/Yb of DTPA as a scrubbing agent is comparable to that of the extraction stage.Batch counter-current extraction experiments further confirm the efficacy of the"push-pull"extraction strategy,with the purity of Lu increasing from 48.0 wt%to 97.4 wt%after 10 extraction stages and 10 scrubbing stages.This study offers a novel approach to the efficient separation of Lu and Yb and demonstrates the potential of the"push-pull"extraction system in rare earth separation processes. 展开更多

In December 2025,the White House released the National Security Strategy for Trump's second term.The United States shifted the focus of its national security strategy from external competition to internal restructuring—both within the United States and within the Western world.The goal was not to abandon the pursuit of global dominance but rather to repair the foundations of American hegemony in terms of power foundation,political ideology,and alliance management.It aims to forge a low-cost,selective,and transactional form of American hegemony.Compared to the National Security Strategies during the Biden administration and Trump's first term,the new report's narrative regarding China is relatively more measured.However,China remains viewed by the Trump administration as the most significant competitor.The United States will intensify its competition with China in economic and technological spheres,strengthen its military deterrence against China in the“Indo–Pacific”region,and exert pressure on China's influence in the Western Hemisphere and other regions.The Sino–US strategic competition is evolving into a new dynamic characterized by long-term competition,mutual balances,and selective engagement.China must analyze the complex implications of the Trump administration's strategic adjustments,enhance its capabilities,and refine its policy toolkit toward the United States.It is necessary to explore new models for“managed cooperation”between China and the United States. 展开更多

Organic compounds are promising electrode materials for aqueous zinc-ion batteries(AZIBs) but largely suffer from poor rate and cycling performance.This work reports that the push-pull electron effect of organic compounds could be used to tune the electrochemical performance of AZIB s.Hexaazatriphenylene-based(HATN) small molecules with different withdrawing or donating groups were synthesized and used as electrodes for AZIBs.Compared to the hydrogen atoms and electrondonating methyl groups,the electron-withdrawing fluorine atoms endow HATN-based small molecule(HATN-6F)with a much-improved redox platform,rate performance and cycling stability.The fluorinated electrode HATN-6F potently amplifies and stabilizes the kinetics of cation co-(de)insertion reactions,concurrently enhancing the conductivity and electron affinity,resulting in improved rate performance and enhanced cycling stability.The combination of theoretical calculations and experimental characterization confirms that the fluorine-rich peripheral environment effectively modifies the distribution of conjugated electrons in HATN,enhancing its affinity for zinc ions and improving its capacity for cations zinc storage.This work demonstrates a new avenue for the design and synthesis of organic electrode with excellent electrochemical performance for ZIBs. 展开更多

Exploring multifunctional interfacial modifiers is an effective approach to addressing interface issues in perovskite solar cells(PSCs)and improving device performance and stability.While most interfacial modifiers focus on passivating defects at the interfaces,there has been limited investigation into the relationship between molecular design and interfacial charge dynamics.This work introduces resonance molecules with a push-pull effect for interfacial modification,allowing for synergistic regulation of passivation effects and charge dynamics.Specifically,FCz-PO,which includes an electron-withdrawing fluorine atom,exhibits superior passivation but poor molecular stacking and charge extraction.In contrast,MCz-PO,featuring an electron-donating methoxy group,provides effective passivation,wellordered molecular packing,and efficient charge extraction and transport.Consequently,PSCs using MCz-PO achieve high power conversion efficiency(PCE)of 24.74%and excellent operational stability.This study suggests that resonance structures can be an effective molecular design strategy for developing interfacial modifiers with both strong passivation capabilities and well-regulated charge dynamics. 展开更多

Ischemic stroke is a major cause of neurological deficits and high disability rate.As the primary immune cells of the central nervous system,microglia play dual roles in neuroinflammation and tissue repair following a stroke.Their dynamic activation and polarization states are key factors that influence the disease process and treatment outcomes.This review article investigates the role of microglia in ischemic stroke and explores potential intervention strategies.Microglia exhibit a dynamic functional state,transitioning between pro-inflammatory(M1)and anti-inflammatory(M2)phenotypes.This duality is crucial in ischemic stroke,as it maintains a balance between neuroinflammation and tissue repair.Activated microglia contribute to neuroinflammation through cytokine release and disruption of the blood-brain barrier,while simultaneously promoting tissue repair through anti-inflammatory responses and regeneration.Key pathways influencing microglial activation include Toll-like receptor 4uclear factor kappa B,mitogen-activated protein kinases,Janus kinase/signal transducer and activator of transcription,and phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin pathways.These pathways are targets for various experimental therapies aimed at promoting M2 polarization and mitigating damage.Potential therapeutic agents include natural compounds found in drugs such as minocycline,as well as traditional Chinese medicines.Drugs that target these regulatory mechanisms,such as small molecule inhibitors and components of traditional Chinese medicines,along with emerging technologies such as single-cell RNA sequencing and spatial transcriptomics,offer new therapeutic strategies and clinical translational potential for ischemic stroke. 展开更多

Modern agriculture relies heavily on resource-intensive and environmentally harmful inputs,while the increasing global population and decreasing arable land demand new strategies to improve sustainable productivity of cereal crops,particularly reducing inorganic nitrogen fertilizer use while simultaneously increasing photosynthesis and grain yield in rice.To improve rice productivity,it is essential to improve photosynthetic nitrogen assimilation and optimize the translocation of carbon and nitrogen products from source to sink tissues.In this review,we first summarize recent advances in the genetic basis for improving grain yield by enhancing photosynthetic carbon and nitrogen assimilation.We then discuss progress in modulating the source-sink relationships to achieve higher yield and improved harvest index.Finally,we explore the necessary optimizations for adapting rice to high-density planting.These advancements are driving the development of sustainable green revolution varieties through the rational design of multi-gene pyramids and artificial intelligence-driven protein engineering. 展开更多

Against the backdrop of the accelerating global clean energy transition and the rapid increase in renewable energy source(RES)penetration,temporal imbalances between supply and demand in power systems are becoming increasingly prominent.Consequently,the phenomenon of negative electricity prices has evolved from sporadic occurrences into an increasingly prevalent market signal.This paper focuses on case studies of negative electricity prices in major international electricity markets(the Netherlands,Germany,Australia)and selected provincial markets in China(Shandong,Zhejiang).It systematically analyzes their underlying causal mechanisms,assesses their multidimensional impacts,and comparatively examines the mitigation strategies adopted across these diverse markets.The study reveals that the core driver of negative prices is the concentrated high generation feed-in from RES during low-load periods.This is concurrently influenced by multiple factors,including insufficient system flexibility,inter-zonal transmission congestion,and constraints imposed by specific market rules such as subsidies and bidding strategies.Major international electricity markets are widely exploring mitigation measures such as optimizing market clearing mechanisms,incentivizing energy storage and demand-side response,and adjusting subsidy policies.In contrast,the occurrence of negative prices in China’s electricity markets,while sharing common drivers,also exhibits complex correlations with domestic factors,notably medium-and long-term contracts and market power dynamics.Consequently,formulating and implementing differentiated and systematic mitigation strategies,drawing upon international experience while being tailored to China’s specific national context,is crucial for the long-term sustainable development of its electricity markets. 展开更多

Nickel-based superalloys(Ni-based superalloys)have attracted extensive attention in laser additive manufacturing(LAM)due to their capability to directly fabricate complex and high-performance structural components.However,the rapid melting and solidification inherent to LAM result in intense thermal cycling,which induces high residual stresses and microstructural heterogeneity within the fabricated parts.Among them,cracks,as the most destructive defects,can have a typical crack density of over five per mm2 without optimized processes.Moreover,the sudden failures of components caused by cracks account for more than 40%of the total failures of additively manufactured nickel-based superalloy components.They can rapidly expand along grain boundaries or brittle phases,significantly weakening the mechanical properties of components and causing sudden failures.To achieve highly reliable additive manufacturing components,it is essential to conduct in-depth research on the types,formation mechanisms of cracks in Ni-based superalloys,and their relationships with microstructure,residual stress,etc.This paper systematically reviews the crack characteristics and formation mechanisms of Ni-based superalloys during the laser additive manufacturing process,post-manufacturing,and service stages and comprehensively summarizes the current mainstream crack suppression strategies,specifically including process parameter optimization,residual stress regulation,alloy composition design,and subsequent post-treatment technologies,as well as incorporating emerging machine learning-assisted methods.The review aims to provide theoretical insights and technical guidance toward the development of crack-free Ni-based superalloy components fabricated by laser additive manufacturing. 展开更多

Ultraviolet(UV)nonlinear optical(NLO)crystals have received substantial interest in advanced laser technology.However,tailoring a UV NLO material with a large second harmonic generation(SHG)response and good UV transparency remains a challenge.Here,inspired by the classic A3-RE2-[BO3]3 parent template,two new rare-earth borate NLO crystals,RbNa2La2(BO3)3(RNLBO-Ⅰ)and Rb0.681Na2.319La2(BO3)3(RNLBO-Ⅱ),were extracted by merging larger ionic radius cations Rb+and La3+simultaneously using a chemical substitution-oriented strategy.As expected,both compounds achieve significant enhancements in SHG activities,reaching 4.5×and 4.3×KDP,respectively,exceeding three times that of the isomorphic Na3Gd2B3O9.Notably,RNLBO-Ⅰdisplayed the highest SHG response among alkali metal RE-borate NLO crystals containing isolated[BO3]groups in the short-wave UV region.Moreover,RNLBO-Ⅰand-Ⅱdemonstrated short UV cutoff edges at 213 and 207 nm,corresponding to wide bandgaps of 5.3 and 5.6 eV,respectively.Additionally,theoretical calculations and dipole moment analysis were conducted to clarify the origin of the enhanced SHG activities of RNLBO-Ⅰand-Ⅱ.The optimal balance between SHG intensity and UV transparency in RNLBO-Ⅰand-Ⅱunderscores their potential as UV NLO candidates and offers valuable insights for fabricating new advanced UV NLO materials. 展开更多

To advance shipping decarbonization,hydrogen is increasingly recognized as a viable zero-carbon fuel.Currently,a hydrogen/diesel dual-fuel medium-speed engine represents an optimal prime mover for ships.However,challenges such as the large cylinder dimensions of marine medium-speed engines and the low temperatures at the combustion chamber walls can hinder efficient flame propagation,leading to the emission of unburnt hydrogen.This not only diminishes the engine's mechanical output but also poses significant safety risks.To address these issues,this study employs computational fluid dynamics(CFD)modelling to explore optimal diesel injection strategies that minimize unburnt hydrogen emissions in such engines.Specifically,this research examines the impacts of the diesel injection start angle,spray tilt angle,and injection duration on hydrogen combustion efficiency.The findings reveal that fine-tuning injection parameters substantially lower the fraction of unburned hydrogen.Adjusting the injection timing from 9.5°CA BTDC to 49.5°CA BTDC decreases the unburnt hydrogen fraction from 50%to 3%.Furthermore,modifying the spray tilt angle from 75.5°to 55.5°further decreases it to 2%,while shortening the injection duration from 35°CA to 34°CA achieves the lowest unburnt hydrogen fraction at just 1%.These results underscore the effectiveness of diesel injection strategies in optimizing the combustion in hydrogen/diesel dual-fuel marine medium-speed engines,offering a pathway for similar applications in the sector. 展开更多

The escalating issue of drug-resistant pathogens,largely driven by the overuse of conventional antibiotics,has become a significant global health threat.Developing alternative therapeutic strategies and fabricating natural biological enzyme materials that mimic the high efficiency,selectivity,and mild-operating conditions of natural enzymes is a promising approach but presents a significant challenge.Nanozymes—nanomaterials exhibiting enzyme-like catalytic activities—have emerged as innovative therapeutic platforms combining intrinsic antimicrobial properties with enhanced drug delivery capabilities.This review systematically elaborates on the concept,evolution,classification,and design synthesis strategy of antibacterial nanozymes,ranging from the nanoscale to the atomic scale,with a focus on their morphology,structure,catalytic activity,antimicrobial properties,stability,and reusability.It examines the antimicrobial mechanisms of nanozymes across three primary pathways:oxidative stress induction,metal ion release,and nonoxidative interactions,and further explores the synergistic outcomes enabled by their multimodal integration.It also evaluates the enhanced antibacterial effects achieved by nanozyme-antibiotic composites(NACs)—engineered hybrid systems that combine nanozymes with traditional antibiotics.Key synergistic mechanisms include increased reactive oxygen species(ROS)production alongside glutathione(GSH)depletion,enhanced antibiotic retention for controlled release,and membrane disruption to facilitate drug entry,resulting in a more potent"1+1>2"effect.Clinical applications of antibacterial nanozymes and NACs are also discussed,focusing on their potential to combat drug-resistant infections.Ultimately,the review identifies current research gaps and proposes future directions,highlighting the crucial role of these nanozyme-based therapies in advancing global efforts against drug-resistant infections. 展开更多

Muscle and bone,key tissues that maintain the body’s structure and function,are closely connected via mechanical and biochemical interactions.The vascular system plays a crucial role in musculoskeletal health,not only by providing nutrients and oxygen but also by regulating growth,regeneration,and metabolism.This review systematically examines the vascular structure and function of the musculoskeletal system,and explores the complex biochemical signaling networks involving myokines,osteokines,and vascular‑derived factors.Vascular dysfunction is a key contributor to the pathogenesis of degenerative diseases like sarcopenia(SP)and osteoporosis(OP),making vascular‑targeted therapies a promising approach for their treatment.Potential strategies for restoring vascular health include molecular targeting,exercise training,nutritional supplementation,cardiovascular pharmacotherapy,hormone therapies,and tissue engineering—all of which may help slow aging‑related musculoskeletal degeneration.Despite significant research progress,challenges remain in the clinical translation of these interventions.Future research should focus on elucidating the molecular mechanisms of muscle‑bone‑vascular interactions and exploring innovative tissue engineering techniques.This review provides a comprehensive understanding of the dynamic interactions between muscle,bone,and vascular systems,highlighting the importance of vascular health in musculoskeletal disease management,and proposes novel vascular‑targeted approaches for the prevention and treatment of musculoskeletal disorders. 展开更多

Lignin is a major by-product of industries such as pulping and biomass refining.However,currently,its high-value utilization rate remains extremely low.Owing to its high carbon content and unique natural aromatic structure,lignin serves as an ideal biomass-derived precursor for preparing porous carbon electrodes for supercapacitors.Existing relevant reviews are lacking in systematic correlation analysis between the characteristics of lignin precursors and the structural evolution of carbon materials,as well as the systematic sorting of their performance enhancement technologies.Centering on the multi-scale structural engineering of lignin-derived porous carbon electrodes,this review systematically summarizes the key technological advancements in improving their supercapacitive performance.It emphasizes elaborating on the structural and performance differences of porous carbons derived from four types of industrial lignin(lignosulfonate,enzymatic hydrolysis lignin,alkali lignin,and organosolv lignin),as well as the research status and regulation mechanisms of three core technologies,including pore structure regulation,surface modification,and composite strategies.Meanwhile,the current core challenges in this field,such as raw material consistency,the balance between pore structure and conductivity,large-scale production,and the standardization of performance evaluation,are analyzed,and four targeted future development directions are proposed:green synthesis approaches,intelligent structural design,device integration,and full life cycle assessment.This review aims to provide theoretical insights and technical references for the design of high-performance lignin-based supercapacitor electrode materials,thereby promoting the efficient,sustainable,and high-value utilization of industrial lignin resources. 展开更多

Development of high performance,flexible piezoelectric nanogenerators(PENGs)is critical for advancing self-powered sensing and microelectronic applications.In this study,a hydrogen-bond substitute strategy was employed to fabricate a multi-layer PENG based on a cellulose/polyvinylidene fluoride(PVDF)blend film matrix,incorporating multi-phase BCZT(0.1BaZr0.2Ti0.8O3-0.9Ba0.7Ca0.3TiO3)ceramic fillers.Structural characterization via SEM and TEM revealed that an intricate hydrogen-bond network facilitated the uniform dispersion of ceramic fillers within the composite film’s sub-layers.In order to study the effect of filler distribution on piezoelectric performance,the single-and double-layer composite films with varying BCZT configurations were produced and evaluated.The results demonstrated that double-layer PENGs exhibit significantly enhanced electrical output compared to their single-layer counterparts,with the D-L3H7 configuration achieving an open circuit voltage(VOC)of 23.13 V and a short circuit current(ISC)of 8.32μA.This enhancement is attributed to increased inter-layer interfaces,which effectively suppressed charge injection and migration,leading to improved charge density.Additionally,the presence of sharp tipped hexagonal tetragonal phase nanoparticles induced an electric field enhancement effect,further optimizing performance. 展开更多

Rice production is increasingly challenged by flooding stress because of global warming and rising sea levels.As the world’s most important staple crop,rice is highly vulnerable to anaerobic and submergence conditions that occur during flooding,particularly at the germination and vegetative stages.Anaerobic environments hinder seedling establishment during germination,while prolonged submergence during the vegetative stage impairs growth,ultimately reducing yield and grain quality.These stresses,driven by extended inundation,trigger a cascade of detrimental physiological responses and represent a major barrier to stable rice production and global food security.In this review,we examine the effects of flooding on rice growth at both the germination and vegetative stages.We further summarize recent advances in the identification of flooding-tolerant germplasm,QTL mapping,genome-wide association study,transcriptomic and proteomic analyses,and other molecular studies.Subsequently,we highlight potential cultivation and regulatory strategies,including genetic,morphological,physiological,and endogenous hormone-related approaches,aimed at enhancing tolerance to anaerobic and submergence stress.Together,these approaches underscore the promise of integrating molecular insights with agronomic practices to mitigate flooding damage and support sustainable rice production. 展开更多
