Neurodegenerative diseases,which mainly include Alzheimer’s disease,Parkinson’s disease,amyotrophic lateral sclerosis,Wilson’s disease,and Huntington’s disease,are a group of disorders characterized by loss of neurons in the brain and spinal cord.However,the underlying pathogenetic mechanisms of these disorders remain unclear.The metal ion hypothesis is considered a possible cause of a variety of neurodegenerative diseases.This hypothesis posits that the homeostatic imbalance of metal ions leads to oxidative stress,neuroinflammation,excessive aggregation of pathological proteins,and other serious consequences in neurons.The powerful endogenous metal ion chelator metallothionein plays an important role in regulating metal ion homeostasis to alleviate neurodegenerative diseases.This article provides an overview of the pathogenesis of neurodegenerative diseases in relation to metal ions such as copper,iron,and zinc and the contribution of metallothionein to the regulation of metal ion homeostasis.The review focuses on the role of metal ions in the course of neurodegenerative diseases and the molecular mechanisms through which endogenous metallothionein ameliorates metal ion overload to alleviate neurodegenerative diseases.A thorough understanding of these molecular mechanisms can provide a theoretical foundation for the development of new therapeutic strategies,with the aim of more effectively treating these devastating diseases in the future. 展开更多

Lithium metal batteries(LMBs)are promising candidates for next-generation high-energy-density storage devices.However,an unstable lithium metal anode poses significant issues that critically compromise battery safety and cycle life,including lithium dendrite formation,solid electrolyte interphase degradation,dead lithium accumulation,and substantial volume fluctuations during cycling.These problems can be addressed by regulating lithium deposition and suppressing side reactions through the modification of copper current collectors using three classes of materials:metal and metal oxide,carbon,and polymer materials.This review comprehensively examines recent advances in the application of these materials as current collector coatings.Particularly,their distinct roles in the lithium deposition process are analyzed to understand how they mitigate the issues associated with the lithium metal anode.Furthermore,their inherent limitations are considered to inform future research directions.While each class of materials offers specific advantages,multifunctionality is required to effectively regulate lithium deposition.In prospect,a novel composite copper current collector design that integrates the merits of the aforementioned advanced materials is proposed.The insights from this review provide valuable guidance for the rational design of modified copper current collectors,which would significantly improve the safety and cycle life of LMBs and advance their commercialization. 展开更多

The recovery of precious metals(PMs)from secondary resources is critical for addressing global supply-chain vulnerabilities and sustainable resource utilization.This review systematically examines the transformative potential of metal-organic frameworks(MOFs)as next-generation adsorbents for PM recovery,focusing on their synthesis,functionalization,and multiscale adsorption mechanisms.We critically analyze conventional pyrometallurgical and hydrometallurgical methods and highlight their limitations in terms of selectivity,energy consumption,and secondary pollution.In contrast,MOFs offer tunable porosity,abundant active sites,and tunable surface chemistry,enabling efficient PM capture via synergistic physical and chemical adsorption.Advanced modification techniques,including direct synthesis and post-synthetic modification,are reviewed to propose strategies for enhancing the adsorption kinetics and selectivity for Au,Ag,Pt,and Pd.Key structure-property relationships are established through multiscale characterization and thermodynamic models,revealing the critical roles of hierarchical porosity,soft donor atoms,and framework stability.Industrial challenges,such as aqueous stability and scalability,are addressed via Zr-O bond strengthening,hydrophobic functionalization,and support immobilization.This study consolidates the experimental and theoretical advances in MOF-based PM recovery and provides a roadmap for translating laboratory innovations into practical applications within the circular-economy framework. 展开更多

Transparent conducting films are indispensable to modern optoelectronic devices due to their unique combination of high transparency and electrical conductivity.While existing fabrication methods—such as physical vapor deposition and solution-based synthesis—are well-established for flat substrates,producing high-quality transparent conductors on non-planar surfaces remains a significant challenge,largely due to difficulties in achieving conformal coverage,nanoscale uniformity,and consistent optoelectrical performance.In this study,we report a conformal deposition model with metal co-doping method on curved surfaces that can produce ultra-thin(≤10 nm),ultra-uniform(±0.5 nm),and ultra-smooth metal films.This work sets a new benchmark for conformal sub-10 nm metal films,whose optoelectrical performance rivals that of planar counterparts,achieving an average visible transmittance of∼88%and sheet resistance of∼8.1Ω·sq-1 with capping layers.In addition,the process can be further extended to a range of optical dielectrics,enabling precise production of advanced conformal coatings.These findings provide practical pathways for optoelectronic applications,including curved transparent electrodes,three-dimensional optical-to-microwave devices,and next-generation smart glasses. 展开更多

The advent of all-solid-state lithium metal batteries(ASSLMBs)holds promise for overcoming the safety hazards and energy density limitations faced by traditional lithium-ion batteries,thereby advancing the industrialization of next-generation energy storage technologies with high safety and specific energy.However,during practical application,three core challenges persist at the interface between the solidstate electrolytes(SSEs)and the lithium metal anode(LMA):Poor physical contact,interfacial side reactions,and growth of lithium dendrites.These interfacial issues constrain the overall performance of ASSLMBs and impede the commercialization process of this battery system.This review begins by examining the underlying mechanisms responsible for the interfacial problems between SSEs and LMA.Building on this foundation,optimization strategies and recent research progress are systematically introduced,classified according to the interfacial components:SSE-side optimizations,interface engineering,and LMA-side treatments.Finally,future research directions,strategies,and optimization schemes addressing the interfacial challenges between SSEs and LMA are prospected.This analysis aims to facilitate critical breakthroughs in the stability,cycling lifespan,and energy density of ASSLMBs,promoting their transition from laboratory innovation to commercial application. 展开更多

This study describes the dynamic behavior of metal nanoparticles on surfaces modulated by reactive gases(CO,NO,H2,H2O,and O2)under soft conditions at low pressure and temperature.Quantum chemical simulations,experimental methods,and machine learning revealed distinct effects:NO promoted nanoparticle fragmentation into highly active single-atom species;H2,H2O,and O2 induced nanoparticle growth;and CO stabilized their structure.This reactive gas modulation(RGM)effect enables flexible control over nanoparticle size and distribution,advancing nanoscale metal tuning.In practical applications,NO gas enhanced the performance of the Pd/C catalyst,facilitating Suzuki-Miyaura cross-coupling under mild conditions(35℃)with superior efficiency.The developed approach was evaluated for other metals and corresponding effects were studied(Ni,Fe,Co,Cu,Au,Pt,Ru,Ir,Rh),demonstrating versatile possibilities to control nanoscale morphology.The results highlight a flexible metal nuclearity control tool based on the RGM effect in the optimization of catalytic systems for fine organic synthesis,opening the way for advances in catalysis and materials science through nanoscale precision.Through a multilevel study using theoretical and experimental approaches,a methodology for a rapid,energy-efficient and easily scalable approach to synthesize single-atom catalyst at the gram-scale was developed. 展开更多

Alkali metal-chalcogen batteries(AMCBs)are one of the most promising next-generation energy storage systems because of their high energy density and reasonably low cost.However,the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode,the shuttle effect of polychalcogenides,and unstable alkali metal anodes during cycling.Owing to MXene's remarkable chemical stability,rich surface functional groups,outstanding electrical conductivity,and superior mechanical flexibility,MXene(transition metal carbides or nitrides)and its composites have been extensively used in different battery components of AMCBs to resolve these issues.Herein,we summarize the recent advances in the design,fabrication,and application of MXene and its composites for high-performance AMCBs.The advantages and issues of AMCBs and several typical solutions are first introduced.Subsequently,we describe the classification and synthetic methods of MXene,with a comparison of the advantages and disadvantages of these methods.Moreover,the relationships between nano/microstructures,synthetic methods of MXene-based materials,and the electrochemical performance of MXene-based AMCBs are systematically summarized and discussed.In addition,technologies for the advanced characterization of the reaction mechanisms of MXene-based materials in AMCBs are also reviewed.Finally,the remaining challenges and future research directions are proposed and discussed. 展开更多

Li metal anodes,with high theoretical capacity(3860 mAh g-1)and low redox potential,are promising for high-capacity rechargeable batteries.Especially,ultra-thin Li metal anodes can improve energy density and minimize lithium excess.However,their poor processability leads to non-uniform Li layers and unstable plating/stripping behavior.In this study,we present a current collector interphase(CCI)-based strategy using a Cu foil coated with a lithiophilic Si3N4 layer,followed by molten Li dip-coating to form around 20 lm Li layer.Furthermore,the scalable dip-coating method,compatibility with large-area current collectors(up to 100 cm2),and stable cycling in pouch cells demonstrate the practical viability of the proposed SNLMA design for commercial lithium metal batteries.During the process,an in-situ Li–Si–N alloy gradient interphase forms at the interface,enhancing wettability and mechanical integrity.This unique gradient CCI provides synergistic lithiophilicity and structural stability,enabling high-performance Li metal batteries.The resulting LixSiy and LixNy phases reduce nucleation barriers and enable uniform Li deposition.As a result,the Si3N4–Li anode paired with a high-loading LCO cathode(22 mg cm-2)achieved 83%capacity retention after 100 cycles.This work offers a scalable and practical CCI design for next-generation Li metal batteries. 展开更多

Radiotherapy(RT) remains an indispensable means in cancer treatment;however,its therapeutic efficacy is often limited by tumor radioresistance and side effect of damage to healthy tissue.The advances in nanotechnology have propelled metal radiosensitizers to forefront of precision medicine.These metal-based radiosensitizations enhance RT efficacy through multifaceted mechanisms of physical dose amplification,chemical catalysis,and biological modulation.Compared to conventional way by employing high atomic number(high-Z) metal materials to enhance energy deposition,emerging strategies such as X-ray induced radiodynamic therapy(X-RDT) and Cerenkov radiation activated photodynamics therapy(CR-PDT),have been developed to synergize RT with deep-tumor reactive oxygen species(ROS) generation under lower radiation dose.In this review,we highlight recent progress in metal-based radiosensitization for cancer therapy,discuss key challenges hindering clinical translation,and emphasize innovations in material design,combinatorial therapies,and clinical oncology.Collectively,these advances may unlock the full potential of metal-based radiosensitizers,paving the way for curative RT with minimal damage to normal tissues. 展开更多

The performance of iron ore pellets was influenced by gangue mineral interactions and alkali metal migration during the oxidation and reduction processes.A novel synergistic strategy was proposed to optimize pellet properties by regulating the liquid phase content coupled with MgO addition.The effects of SiO2and MgO contents on liquid phase generation,pellet microstructure,compressive strength,reduction swelling index(RSI),and reduction index(RI)were systematically investigated.The results showed that the increasing SiO2content significantly enhanced liquid phase formation,thereby improving compressive strength and reducing RSI,but lowering RI.MgO promoted the formation of MgxFe3-xO4during oxidation,increasing porosity and enhancing RI while slightly compromising mechanical strength.In addition,MgxFe3-xO4reduced the expansion during the initial reduction stage(Fe2O3→Fe3O4).Optimal performance was achieved when the liquid phase content in the roasted pellet was maintained at 11%-13%and MgO at 2.0%-2.6%,with compressive strength exceeding 2500 N,RSI below 20%,and RI above 64%.In addition,doubling the liquid phase content reduced the concentration of alkali metals diffused into the iron oxide lattice by approximately 50%,mitigating the localized precipitation of metallic iron whiskers during the final reduction stage(FexO→Fe).Alkali metal doped into iron oxides during oxidation had a more pronounced effect on swelling behavior than the reduction process.These findings offered practical insights into high-performance pellet production under industrial conditions. 展开更多

Intensifying the electronic metal-support interaction(EMSI)between organometal halide perovskites(OMHPs)photocatalysts and hydrogen evolution reaction(HER)co-catalyst is crucial for realizing efficient interfacial charge transfer and solar-to-hydrogen(STH)conversion.Although atomically dispersed catalysts(ADCs)are prone to form stronger EMSI than nanoparticles with support,assembling ADCs on OMHPs remains a great challenge due to the ionic nature and thermal instability of OMHPs.Herein,we realize the design of two-dimensional(2D)OMHPP)loaded with nonnoble metal-based ADCs,namely tungsten ADCs(WADCs),for the first time.We show that WADCscoordinated with two sulfur and two oxygen atoms are anchored on the surface of PMA2PbI4via a W-O-Pb link.The resulting WADCs-decorated PMA2PbI4(WADCs/S-PMA2PbI4)exhibits an extraordinary interfacial charge transfer efficiency of 94.7%,which is much higher than that of Pt/PMA2PbI4(61.7%).Moreover,WADCscan effectively extend the lifetime of hot carriers and work as the active sites for HER.Consequently,WADCs/S-PMA2PbI4shows a photocatalytic HER activity superior to that of Pt/PMA2PbI4and 30 times that of bare PMA2PbI4with a record turnover frequency(TOF)of 516.3 h-1per W atom.This work opens a new avenue for designing cost-effective perovskite-based catalysts for solar hydrogen production. 展开更多

In recent years,organic solar cells(OSCs)have experienced significant advancements in both efficiency and stability,largely due to the emergence of novel polymer donors and non-fullerene acceptors(NFAs).Among these,metal complex photovoltaic materials,with their unique properties,play a crucial role in certain applications.Compared to pure organic materials,metal-containing conjugated organic molecules offer a versatile range of molecular semiconductors for OSCs.Organic photovoltaic materials incorporating metal complexes provide numerous advantages,including the possibility of having triplet excitons,metal-metal and/or metal-ligand interactions,high photoluminescence quantum yields,and tunable energy levels.These benefits can extend the exciton lifetime and diffusion length,reinforce molecular interactions for greater stability,reduce non-radiative recombination losses,and adjust charge transfer state to boost current generation,ultimately improving OSC performance.In this review,metal complex-based materials for use in OSCs have been summarized.Firstly,different metal complex materials as building units are investigated.Secondly,the mechanisms and structure-property relationships of metal complex-based materials are presented in detail.Finally,the challenges and future prospects for metal complex photovoltaics in achieving high-performance devices are summarized. 展开更多

Metal-support interaction(MSI) is crucial for fine-tuning the active-site structure of supported catalysts and enhancing performance.Here,we present an ammonia-directed reactive gas-metal-support interaction(RGMSI),in which NH3 reduces ZnO and assembles an anti-perovskite Ni3ZnN structure with interstitial nitrogen,significantly boosting hydrogenation efficiency.Nitrogen incorporation expands the lattice parameter,increasing the(111) lattice spacing from 2.04Å in Ni to 2.18Å in Ni3ZnN,with an extended Ni-Ni interatomic distance from 2.49Å to 2.65Å.Additionally,Ni-N coordination shifts the d-band center downward and induces electron deficiency in Ni via charge transfer.These modifications optimize reactant adsorption on the tailored Ni3ZnN structure compared to Ni,leading to a remarkable increase in 1,3-butadiene hydrogenation selectivity from 30.0 % to 92.9 %,along with an enhanced TOF from 0.067 s-1 to 0.079 s-1.These findings highlight RGMSI as a versatile and effective strategy for designing supported metal catalysts,offering new insights into selective hydrogenation catalysis. 展开更多

Metal-organic frameworks(MOFs)with mononuclear metal ion nodes have garnered significant attention in the electrocatalytic field owing to their high surface area and tunable structures,but their development is critically hindered by the limitation of active site availability.In contrast,multinuclear MOFs exhibit notable advantages by offering multi-metal active sites,constructing complex structures,enhancing structural and thermal stability,and coupling with in-depth studies on catalytic mechanisms,endowing them great application potential in complex multi-electron reactions.This work provides a comprehensive review on the precise construction,in-situ characterizations,reaction mechanisms,modulation strategies,and electrocatalytic applications of multinuclear MOFs,underlying their role in electrocatalytic processes with a focus on adsorption,active sites,and electron transfer.The effects of spin,polarization,orbital coupling,and pore confinement on catalytic performance are systematically elucidated.Furthermore,the unique tuning strategies of multinuclear MOFs are summarized to guide the precise construction,including adjusting the type and number of metal cores,optimizing electronic structures,and manipulating defects.Lastly,the future trends in the development of multinuclear MOFs for electrocatalysis are envisioned,laying a solid foundation for their practical applications. 展开更多

We present a method for modifying metal organic frameworks(MOFs)surface functionalization using metal-free atom transfer radical polymerization(ATRP).Amino-functionalized zeolitic imidazolate frameworks-8(ZIF-8-NH2)was synthesized at room temperature,and ZIF-8-Br was obtained by the reaction of the amino group in ZIF-8-NH2 with the acyl bromide group in 2-bromoisobutyl bromide(BIBB),thereby introducing secondary bromine groups onto the surface of ZIF-8-NH2.Then,ZIF-8-g-poly(methyl methacrylate)(ZIF-8-g-PMMA)hybrid materials were synthesized using ZIF-8-Br as an initiator via surface-initiated metal-free atom transfer radical polymerization(metal-free ATRP).The structural and morphological evolutions were monitored using Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS),Xray powder diffraction(XRD)and scanning electron microscopy(SEM)measurements.Thermogravimetry(TG)analysis verified that ZIF-8-g-PMMA had excellent thermal stability,and the water stability test demonstrated that after grafting PMMA from the ZIF-8-NH2 surface,the hydrophobicity and water stability were improved significantly.The BET results proved that ZIF-8-g-PMMA had a high specific surface area of 835.24 m2/g.By immobilizing ZIF-8-g-PMMA hybrid material on fabrics,the modified fabrics exhibit excellent superhydrophobicity,with the water contact angle as high as 159.2°.Attributed to the synergistic effect of the micro-and nano-graded porous structure and low-surface-energy PMMA coatings,ZIF-8-g-PMMA hybrid material modified fabrics achieves highly efficient oil-water separation,with excellent adsorption effects on both light and heavy oils.Among them,the heavy oil can pass through the modified fabric within seconds with an oil-water separation efficiency of 96%.This method will further expand the scope of application of metal-free ATRP technology and MOFs materials. 展开更多

The intrinsic characteristics of the Li metal anode,particularly its ultra-high specific capacity(3860 mAh g−1)and low redox potential(−3.04 V vs.SHE),theoretically make it ideal for high-rate charge/discharge operations.However,the high Li selfdiffusion barrier causes uncontrolled plating/stripping dynamics and severe volume fluctuations,hindering stable performance at elevated current densities.In this study,we introduced an artificial solid-electrolyte interphase(ASEI)engineered with a bilayer that transcends conventional planar deposition,facilitating Li nucleation and growth along three-dimensional electronic percolation pathways.This spatially distributed,lateral plating morphology significantly reduced charge-transfer resistance,suppressed dendrite formation,and mitigated cell degradation under high charging currents.Consequently,the ASEI-enabled Li metal electrode maintained low overpotentials at an areal capacity of 10 mAh cm−2 and a current density of 20 mA cm−2 for over 300 h,while demonstrating outstanding rate capability and long-term cyclability in LiFePO4(LFP)‖Li and LiNi0.8Co0.1Mn0.1O2(NCM811)‖Li full cells.By elucidating these intrinsic anode behaviors,our findings establish a fundamental design strategy for high-rate performance,potentially advancing the commercialization of Li metal batteries. 展开更多
