文摘An easily stackable multi-layer quasi-zero-stiffness(ML-QZS)meta-structure is proposed to achieve highly efficient vibration isolation performance at low frequency.First,the distributed shape optimization method is used to design the unit cel,i.e.,the single-layer QZS(SL-QZS)meta-structure.Second,the stiffness feature of the unit cell is investigated and verified through static experiments.Third,the unit cells are stacked one by one along the direction of vibration isolation,and thus the ML-QZS meta-structure is constructed.Fourth,the dynamic modeling of the ML-QZS vibration isolation metastructure is conducted,and the dynamic responses are obtained from the equations of motion,and verified by finite element(FE)simulations.Finally,a prototype of the ML-QZS vibration isolation meta-structure is fabricated by additive manufacturing,and the vibration isolation performance is evaluated experimentally.The results show that the vibration isolation performance substantially enhances when the number of unit cells increases.More importantly,the ML-QZS meta-structure can be easily extended in the direction of vibration isolation when the unit cells are properly stacked.Hence,the ML-FQZS vibration isolation meta-structure should be a fascinating solution for highly efficient vibration isolation performance at low frequency.

文摘Solar steam generation(SSG)is widely regarded as one of the most sustainable technologies for seawater desalination.However,salt fouling severely compromises the evaporation performance and lifetime of evaporators,limiting their practical applications.Herein,we propose a hierarchical salt-rejection(HSR)strategy to prevent salt precipitation during long-term evaporation while maintaining a rapid evaporation rate,even in high-salinity brine.The salt diffusion process is segmented into three steps—insulation,branching diffusion,and arterial transport—that significantly enhance the salt-resistance properties of the evaporator.Moreover,the HSR strategy overcomes the tradeoff between salt resistance and evaporation rate.Consequently,a high evaporation rate of 2.84 kg m^(-2) h^(-1),stable evaporation for 7 days cyclic tests in 20 wt%NaCl solution,and continuous operation for 170 h in natural seawater under 1 sun illumination were achieved.Compared with control evaporators,the HSR evaporator exhibited a>54%enhancement in total water evaporation mass during 24 h continuous evaporation in 20 wt%salt water.Furthermore,a water collection device equipped with the HSR evaporator realized a high water purification rate(1.1 kg m^(-2) h^(-1)),highlighting its potential for agricultural applications.

文摘Li-rich Mn-based oxides(LRMOs)hold great promise as next-generation cathode materials for high-energy Li-ion batteries because of their low cost and high capacity.Nevertheless,the practical application of LRMOs is impeded by their low initial Coulombic efficiency and rapid voltage decay.Herein,a V-doped layered-spinel coherent layer is constructed on the surface of a Co-free LRMO through a simple treatment with NH_(4)VO_(3).The layered-spinel coherent layer with 3D ion channels enhanced Li+diffusion efficiency,mitigates surface-inter-face reactions and suppresses irreversible oxygen release.Notably,V-doping significantly reduces the Bader charge of oxygen atoms,thereby impeding excessive oxidation of oxygen ions and further enhancing the stability of O-redox.The modified LRMO exhibites a remarkable initial Coulombic efficiency of 91.6%,signifi-cantly surpassing that of the original LRMO(74.4%).Furthermore,the treated sample showes an impressive capacity retention rate of 91.9%after 200 cycles,accompanied by a voltage decay of merely 0.47 mV per cycle.The proposed treatment approach is straightforward and significantly improves the initial Coulombic efficiency,voltage stability,and capacity stability of LRMO cathode materials,thus holding considerable promise for the development of high-energy Li-ion batteries.

文摘Relaxor ferroic dielectrics have garnered increasing attention in the past decade as promising materials for energy storage.Among them,relaxor antiferroelectrics(AFEs)and relaxor ferroelectrics(FEs)have shown great promise in term of high energy storage density and efficiency,respectively.In this study,a unique phase transition from relaxor AFE to relaxor FE was achieved for the first time by introducing strong-ferroelectricity BaTiO_(3)into NaNbO_(3)-BiFeO_(3)system,leading to an evolution from AFE R hierarchical nanodomains to FE polar nanoregions.A novel medium state,consisting of relaxor AFE and relaxor FE,was identified in the crossover of 0.88NaNbO_(3)–0.07BiFeO_(3)–0.05BaTiO_(3)ceramic,exhibiting a distinctive core-shell grain structure due to the composition segregation.By harnessing the advantages of high energy storage density from relaxor AFE and large efficiency from relaxor FE,the ceramic showcased excellent overall energy storage properties.It achieved a substantial recoverable energy storage density W_(rec)~13.1 J/cm^(3)and an ultrahigh efficiencyη~88.9%.These remarkable values shattered the trade-off relationship typically observed in most dielectric capacitors between W_(rec)andη.The findings of this study provide valuable insights for the design of ceramic capacitors with enhanced performance,specifically targeting the development of next generation pulse power devices.

文摘High-density linkage maps are essential tools for genome analysis of various biological traits. Our developed compact multi-gel system, HEGS （high efficiency genome scanning） is a high-throughput and high-cost-performance electrophoresis apparatus. Using this system, a high-density （average interval 2.3 cM） map with 1 065 AFLP and 63 SSR markers was constructed from recombinant inbred lines of a japonica and indica hybrid in just two months of electrophoreses by a single person. More than 50% of the mapped AFLP markers were commonly polymorphic for several combinations between japonica and indica rice and 15% were applicable for genetically closer crosses between upland and lowland types of japonica rice. This system can be used for rapid analyses of all kinds of markers.

文摘Superhydrophobic glass has inspiring development prospects in endoscopes,solar panels and other engineering and medical fields.However,the surface topography required to achieve superhydrophobicity will inevitably affect the surface transparency and limit the application of glass materials.To resolve the contradiction between the surface transparency and the robust superhydrophobicity,an efficient and low-cost laser-chemical surface functionalization process was utilized to fabricate superhydrophobic glass surface.The results show that the air can be effectively trapped in surface micro/nanostructure induced by laser texturing,thus reducing the solid-liquid contact area and interfacial tension.The deposition of hydrophobic carbon-containing groups on the surface can be accelerated by chemical treatment,and the surface energy is significantly reduced.The glass surface exhibits marvelous robust superhydrophobicity with a contact angle of 155.8°and a roll-off angle of 7.2°under the combination of hierarchical micro/nanostructure and low surface energy.Moreover,the surface transparency of the prepared superhydrophobic glass was only 5.42%lower than that of the untreated surface.This superhydrophobic glass with high transparency still maintains excellent superhydrophobicity after durability and stability tests.The facile fabrication of superhydrophobic glass with high transparency and robustness provides a strong reference for further expanding the application value of glass materials.

文摘Organic-inorganic hybrid perovskite solar cells(PSCs)have garnered significant attention due to their high power conversion efficiency(PCE),low cost,and solution-processability.However,a substantial gap remains in the certified efficiency of single-junction PSCs,primarily due to defects in perovskite films that accelerate nonradiative recombination of carriers.In this study,we designed a multifunctional thiourea derivative,amidinethiourea(ATU),as an additive to modulate the crystallization process of perovskite films and inhibit the formation of organic cations and iodine vacancies.Our work leverages the strong hydrogen-bonding interactions between guanidinium molecules and organic amine components,as well as the robust coordination effects between the C=S bonds in thiourea and Pb^(2+)ions.We demonstrate that ATU treatment significantly enhances the crystallinity of perovskite films,reduces defects,and improves charge transport properties.The ATU-treated PSCs achieved a PCE of 25.32%,with enhanced operational stability and reduced leakage current.Additionally,the ATU-treated perovskite films exhibited superior humidity and light-soaking stability,retaining 85.2%of their initial efficiency after 1500 h of exposure to ambient conditions.

文摘Anion exchange membranes(AEMs)combining high hydroxide conductivity and alkali-resistant stability have become a major challenge for the long-term development of anion exchange membrane fuel cells(AEMFCs).Here,we designed a series of poly(mequitazine-terphenyl piperidinium)(QPMTP-X)AEMs with dual-functionalized quaternary ammonium cations by introducing a certain proportion of large steric hindrance mequitazine(MEQ)molecular building unit into the poly(aryl piperidinium)backbone.QPMTP-X retains the excellent mechanical properties of the poly(aryl piperidinium),while also combining the alkaline stability and high ionic conductivity exhibited by MEQ with flexible quinuclidinium side chains,achieving an overall improvement of membrane performance.Notably,QPMTP-30 exhibits an ultra-high conductivity of up to 206.83 mS cm^(-1)and excellent alkaline stability(over 95%conductivity is maintained after 1000 h of conditioning in 2 M NaOH at 80℃).In fuel cell performance test,QPMTP-30 achieves a peak power density(PPD)of 974.5 mW cm^(-2)and operates stably at 80℃for more than 60 h(0.1 A cm^(-2)).Incorporating large steric hindrance building blocks and multi-cations into the poly(aryl piperidinium)backbone not only synergizes the development of highperformance AEMs but also opens up new ideas for the structural design of future AEMs.

文摘The stability of perovskite solar cells(PSCs)is adversely affected by nonradiative recombination resulting from buried interface defects.Herein,we synthesize a polyionic liquid,poly(p-vinylbenzyl trimethylam-monium hexafluorophosphate)(PTA),and introduce it into the buried interface of PSCs.The quaternary ammonium cation(N(-CH_(3))^(3+))in PTA can fill the vacancies of organic cations within the perovskite structure and reduce shallow energy level defects.Additionally,the hexafluorophosphate(PF6−)in PTA forms a Lewis acid-base interaction with Pb^(2+)in the perovskite layer,effectively passivating deep en-ergy level defects.Furthermore,hydrogen bonding can be established between organic cations and the PF6−anion,preventing the formation of shallow energy level defects.Through this synergistic mecha-nism,the deep and shallow energy level defects are effectively mitigated,resulting in improved device performance.As a result,the resulting treated inverted PSC exhibits an impressive power conversion ef-ficiency(PCE)of 24.72%.Notably,the PTA-treated PSCs exhibit remarkable stability,with 88.5%of the original PCE retained after undergoing heat aging at 85℃ for 1078 h,and 89.1%of the initial PCE main-tained following continuous exposure to light for 1100 h at the maximum power point.Synergistically suppressing multiple defects at the buried interface through the use of polyionic liquids is a promising way to improve the commercial viability of PSCs.

文摘The electrocatalytic water-splitting process is widely acknowledged as the most sustainable and environmentally friendly technology for hydrogen(H2)production.However,its energy efficiency is significantly constrained by the kinetically slow oxygen evolution reaction(OER)at the anode,which accounts for about 90%of the electrical energy consumption in the water-splitting process.A new strategy is urgently needed to reduce its energy consumption.In recent years,electrochemical oxidation of small molecules has been considered for replacement of OER for efficient H2 production,due to its benign operational conditions,low theoretical thermodynamic potential,high conversion efficiency and selectivity,and environmental sustainability.Hybrid electrolysis systems,by integrating cathodic hydrogen evolution reaction with anodic oxidation of small molecules,have been introduced,which can generate high-purity H2 and produce value-added products or pollutant degradation.In this review,we highlight the recent advancements and significant milestones achieved in hybrid water electrolysis systems.The focus is on non-noble metal electrocatalysts,reaction mechanisms,and the construction of electrolyzers.Additionally,we present the prevailing challenges and future perspectives pertinent to the evolution of this burgeoning technology.
