In this study,an inverse design framework was established to find lightweight honeycomb structures(HCSs)with high impact resistance.The hybrid HCS,composed of re-entrant(RE)and elliptical annular re-entrant(EARE)honeycomb cells,was created by constructing arrangement matrices to achieve structural lightweight.The machine learning(ML)framework consisted of a neural network(NN)forward regression model for predicting impact resistance and a multi-objective optimization algorithm for generating high-performance designs.The surrogate of the local design space was initially realized by establishing the NN in the small sample dataset,and the active learning strategy was used to continuously extended the local optimal design until the model converged in the global space.The results indicated that the active learning strategy significantly improved the inference capability of the NN model in unknown design domains.By guiding the iteration direction of the optimization algorithm,lightweight designs with high impact resistance were identified.The energy absorption capacity of the optimal design reached 94.98%of the EARE honeycomb,while the initial peak stress and mass decreased by 28.85%and 19.91%,respectively.Furthermore,Shapley Additive Explanations(SHAP)for global explanation of the NN indicated a strong correlation between the arrangement mode of HCS and its impact resistance.By reducing the stiffness of the cells at the top boundary of the structure,the initial impact damage sustained by the structure can be significantly improved.Overall,this study proposed a general lightweight design method for array structures under impact loads,which is beneficial for the widespread application of honeycomb-based protective structures. 展开更多

Memristors have emerged as a transformative technology in the realm of electronic devices,offering unique advantages such as fast switching speeds,low power consumption,and the ability to sensor-memory-compute.The applications span across non-volatile memory,neuromorphic computing,hardware security,and beyond,prompting memristors to become a versatile solution for next-generation computing and data storage systems.Despite enormous potential of memristors,the transition from laboratory prototypes to large-scale applications is challenging in terms of material stability,device reproducibility,and array scalability.This review systematically explores recent advancements in high-performance memristor technologies,focusing on performance enhancement strategies through material engineering,structural design,pulse protocol optimization,and algorithm control.We provide an in-depth analysis of key performance metrics tailored to specific applications,including non-volatile memory,neuromorphic computing,and hardware security.Furthermore,we propose a co-design framework that integrates device-level optimizations with operational-level improvements,aiming to bridge the gap between theoretical models and practical implementations. 展开更多

Biohydrogen, produced via microbial fermentation of biomass waste, is poised to play a pivotal role in China's green energy transition. Nonetheless, significant obstacles such as high costs, unstable production dynamics, regulatory and metabolic inefficiencies, and limited actual hydrogen yields hinder large-scale application. Addressing these challenges necessitates the integration of machine learning and synthetic biology, forming a robust pathway to enhanced process efficacy and output consistency. The convergence of artificial intelligence (AI) and biotechnology (BT) is revolutionizing biohydrogen production by shifting from traditional empirical methodologies to predictive, engineering-based frameworks. AI equips researchers to interpret and optimize complex metabolic and genetic networks through machine learning and genome-scale modeling. Concurrently, BT is evolving to manipulate microbial communities holistically via synthetic ecology and dynamic modeling. Here, we propose a “digital microbial community” paradigm, intergating multi-scale metabolic modeling and emergent property prediction, AI-powered ecological niche decomposition and closed-loop BT enhanced evolutionary framework for continuous optimization of digital twins through experimental feedback. This fusion facilitates the rational design and real-time optimization of programmable microbial ecosystems, greatly enhancing biohydrogen producing control and efficiency. The transition to digital and data-driven design, utilizing multi-omics and ecosystem-level analytics, further bolsters precision and scalability. While moving from single cells to complex microbial consortia introduces challenges, such as non-linear dynamics and ecosystem stability, the synergy of AI and BT underpins the intelligent, resilient, and sustainable production of biohydrogen, thereby reinforcing its potential as a foundational component of China's renewable energy landscape. 展开更多

Waverider design based on osculating theory presents two critical issues:robust specification of design curves and accurate solution of the basic flowfield.Although the existing parametric approaches have advanced rapid configuration generation through geometric parameterization frameworks,they critically neglect the inherent coupling between aerodynamic constraints and geometric design parameters.To overcome this limitation,an Aerodynamics-Informed Parametric(AIP)method is developed by analytically deriving three waverider design curves and integrating them with the second-order curved shock theory.This method enables rapid waverider surface design while accounting for inflow conditions and shock wave geometry.Three typical waveriders,each featuring distinct combinations of design curves as inputs,are constructed and evaluated through inviscid and viscous numerical simulations to validate the applicability and accuracy of the AIP method.The results indicate that waveriders derived using the AIP method successfully reproduce the preassigned shock waves and original flowfields.Compared to traditional waverider design techniques based on the method of characteristics,the AIP method reduces computation time by approximately 94%,while maintaining errors in the inviscid lift-to-drag ratio,viscous lift-to-drag ratio,and volumetric efficiency below 0.1%,4.0%,and 0.1%,respectively.Additionally,a specially designed model is fabricated for the wind-tunnel tests to analyze the hypersonic aerodynamic performance of the waverider.Both numerical and experimental results confirm the feasibility of the AIP method,making it a promising candidate for waverider design and optimization. 展开更多

Machine learning(ML)is recognized as a potent tool for the inverse design of environmental functional material,particularly for complex entities like biochar-based catalysts(BCs).Thus,the tailored BCs can have a distinct ability to trigger the nonradical pathway in advance oxidation processes(AOPs),promising a stable,rapid and selective degradation of persistent contaminants.However,due to the inherent“black box”nature and limitations of input features,results and conclusions derived from ML may not always be intuitively understood or comprehensively validated.To tackle this challenge,we linked the front-point interpretable analysis approaches with back-point density functional theory(DFT)calculations to form a chained learning strategy for deeper sight into the intrinsic activation mechanism of BCs in AOPs.At the front point,we conducted an easy-to-interpret meta-analysis to validate two strategies for enhancing nonradical pathways by increasing oxygen content and specific surface area(SSA),and prepared oxidized biochar(OBC500)and SSA-increased biochar(SBC900)by controlling pyrolysis conditions and modification methods.Subsequently,experimental results showed that OBC500 and SBC900 had distinct dominant degradation pathways for 1O2 generation and electron transfer,respectively.Finally,at the end point,DFT calculations revealed their active sites and degradation mechanisms.This chained learning strategy elucidates fundamental principles for BC inverse design and showcases the exceptional capacity to integrate computational techniques to accelerate catalyst inverse design. 展开更多

Automation and intelligence have become the primary trends in the design of investment casting processes.However,the design of gating and riser systems still lacks precise quantitative evaluation criteria.Numerical simulation plays a significant role in quantitatively evaluating current processes and making targeted improvements,but its limitations lie in the inability to dynamically reflect the formation outcomes of castings under varying process conditions,making real-time adjustments to gating and riser designs challenging.In this study,an automated design model for gating and riser systems based on integrated parametric 3D modeling-simulation framework is proposed,which enhances the flexibility and usability of evaluating the casting process by simulation.Firstly,geometric feature extraction technology is employed to obtain the geometric information of the target casting.Based on this information,an automated design framework for gating and riser systems is established,incorporating multiple structural parameters for real-time process control.Subsequently,the simulation results for various structural parameters are analyzed,and the influence of these parameters on casting formation is thoroughly investigated.Finally,the optimal design scheme is generated and validated through experimental verification.Simulation analysis and experimental results show that using a larger gate neck(24 mm in side length) and external risers promotes a more uniform temperature distribution and a more stable flow state,effectively eliminating shrinkage cavities and enhancing process yield by 15%. 展开更多

The oxygen evolution reaction(OER)suffers from sluggish kinetics,necessitating efficient electrocatalysts to reduce overpotentials in water splitting.Currently recognized OER mechanisms primarily include the adsorbate evolution mechanism(AEM),lattice oxygen mechanism(LOM),and oxide path mechanism(OPM).Compared to AEM,limited by scaling relationships,and LOM,constrained by stability issues,the OPM offers a promising alternative by enabling direct O-O bond formation via dual active sites,thus bypassing*OOH intermediates and lattice O involvement and achieving a balance between activity and durability.However,activating the OPM process requires precise control over the spatial and electronic structure of active sites,making the design of OPM-based catalysts challenging.While previous reviews have focused on homo/heteronuclear diatomic perspectives of OPM-based catalysts,it is urgent to systematically summarize design strategies to provide a rational reference for their development.Herein,a review of design strategies for OPM-based OER catalysts across three scales is comprehensively presented,including in-situ engineering,doping-enabled sites reconstruction,and introducing new sites for nanoparticles,direct synthesis or post-treatments for molecular catalysts,and doping or template strategies for atom pairs or arrays.The unique advantage of atom arrays is also highlighted,and their future research directions and possible strategies are discussed.This review provides a systematic summary and forward-looking perspectives for rationally designing high-performance OPM-based OER catalysts. 展开更多

Energy shortage has become one of themost concerning issues in the world today,and improving energy utilization efficiency is a key area of research for experts and scholars worldwide.Small-diameter heat exchangers offer advantages such as reduced material usage,lower refrigerant charge,and compact structure.However,they also face challenges,including increased refrigerant pressure drop and smaller heat transfer area inside the tubes.This paper combines the advantages and disadvantages of both small and large-diameter tubes and proposes a combined-diameter heat exchanger,consisting of large and small diameters,for use in the indoor units of split-type air conditioners.There are relatively few studies in this area.In this paper,A theoretical and numerical computation method is employed to establish a theoretical-numerical calculation model,and its reliability is verified through experiments.Using this model,the optimal combined diameters and flow path design for a combined-diameter heat exchanger using R32 as the working fluid are derived.The results show that the heat transfer performance of all combined diameter configurations improves by 2.79%to 8.26%compared to the baseline design,with the coefficient of performance(COP)increasing from 4.15 to 4.27~4.5.These designs can save copper material,but at the cost of an increase in pressure drop by 66.86%to 131.84%.The scheme IIIH,using R32,is the optimal combined-diameter and flow path configuration that balances both heat transfer performance and economic cost. 展开更多

This study reconsiders the evolving relationship between architects and computa-tional systems in the context of increasingly embedded digital and intelligent technologies.Rather than focusing only on what tools can do,it looks at how tool-making itself helps reshape how architects think and work.Through four web-based generative design applications―SIM-Forms,ANYSite,NEXUSpace,and FLEXUrban―this paper investigates how architects engage with computation not only as tool users,but also as developers of generative algorithms,and organizers of workflows.Based on these cases,the paper proposes a framework of three interrelated mechanisms of human-computer collaboration:reconstructing intuitive media,adopting algorithmic design thinking,and organizing programmable design systems.The framework aims to provide a conceptual foundation for reimagining how architects can stay actively involved in shaping the tools and processes that define digital design today. 展开更多

The electrochemical oxidation of biomass-derived platform molecule 5-hydroxymethylfurfural(HMF)represents a crucial pathway for green transformation into high-value chemicals,yet its reaction pathway selectivity,efficiency,and catalyst stability are strongly dependent on the electrolyte pH environment.Under alkaline conditions,high OH−concentration facilitates preferential aldehyde group oxidation and efficient deprotonation,enabling highly efficient synthesis of 2,5-furandicarboxylic acid,but simultaneously induces HMF self-degradation and complicates product separation.As pH decreases,the reaction mechanism shifts toward enhanced hydroxymethyl oxidation,leading to intermediate accumulation(such as 5-hydroxymethyl-2-furancarboxylic acid,2,5-diformylfuran,and 5-formyl-2-furancarboxylic acid)with challenging selectivity control and significantly slowed reaction kinetics.This review comprehensively examines the systematic differences in HMF oxidation pathways and surface catalytic mechanisms across the full pH range from alkaline to acidic conditions.Addressing the distinct reaction characteristics and core challenges in alkaline,near-neutral,and acidic media,we systematically evaluate design strategies for high-efficiency electrocatalysts and explore reactor design aspects.Future research should focus on process integration(with tailored reactor design)for energy consumption reduction in alkaline systems,targeted synthesis of diverse oxidation products in near-neutral systems,and innovative catalyst development for acidic systems,thereby advancing the efficiency,selectivity,and practical application of HMF electrooxidation technologies across the entire pH spectrum through synergistic optimization of catalyst,reactor,and process. 展开更多

In recent years,the use of deep learning to replace traditional numerical methods for electromagnetic propagation has shown tremendous potential in the rapid design of photonic devices.However,most research on deep learning has focused on single-layer grating couplers,and the accuracy of multi-layer grating couplers has not yet reached a high level.This paper proposes and demonstrates a novel deep learning network-assisted strategy for inverse design.The network model is based on a multi-layer perceptron(MLP)and incorporates convolutional neural networks(CNNs)and transformers.Through the stacking of multiple layers,it achieves a high-precision design for both multi-layer and single-layer raster couplers with various functionalities.The deep learning network exhibits exceptionally high predictive accuracy,with an average absolute error across the full wavelength range of 1300–1700 nm being only 0.17%,and an even lower predictive absolute error below 0.09%at the specific wavelength of 1550 nm.By combining the deep learning network with the genetic algorithm,we can efficiently design grating couplers that perform different functions.Simulation results indicate that the designed single-wavelength grating couplers achieve coupling efficiencies exceeding 80%at central wavelengths of 1550 nm and 1310 nm.The performance of designed dual-wavelength and broadband grating couplers also reaches high industry standards.Furthermore,the network structure and inverse design method are highly scalable and can be applied not only to multi-layer grating couplers but also directly to the prediction and design of single-layer grating couplers,providing a new perspective for the innovative development of photonic devices. 展开更多

Rechargeable aluminium-ion batteries(RAIBs)are promising candidates for sustainable energy storage owing to their low cost,safety,and resource abundance.However,the lack of durable cathode materials restricts their development.Here,we propose a topology-guided design strategy by synthesizing three thioether-bridged naphthoquinone polymers from 1,4-naphthoquinone.Structural characterization combined with density functional theory calculations confirms that polymerization reduces crystallinity,enhances thermal stability,and extendsπ-conjugation,with the para-topology providing the most favorable configuration and strongest AlCl2+coordination.The nearly planar para-naphthoquinone polymer(p-PNQ)exhibits an extended conjugated backbone,reduced bandgap,and uniform electrostatic potential distribution.Electrochemical tests reveal that p-PNQ delivers 146 mAh g-1 initially at 0.1 A g-1 and a 97.2%retention after 500 cycles,surpassing pristine 1,4-NQ and o-/m-isomers.Ex situ analyses confirm that redox activity originates from reversible coordination between carbonyl groups and AlCl2+species.This study establishes molecular topology as a key parameter for designing organic cathodes,and demonstrates that topology-controlled strategies enable durable,high-performance cathodes for energy storage in RAIBs. 展开更多

Cutterhead clogging remains a significant challenge in slurry shield tunneling,particularly in clay-rich strata,leading to reduced efficiency and increased operational costs.This paper presents a comparative numerical study of three common slurry shield cutterhead designs,atmospheric soft-soil cutterhead,atmospheric mix-ground cutterhead,and conventional cutterhead,using a coupled computational fluid dynamics–discrete element method(CFD–DEM)approach.The integrated CFD–DEM model allows for a detailed examination of slurry flow dynamics and granular material behavior within the cutterhead chamber.The analysis focuses on muck discharge efficiency,quantifying the volume of excavated material effectively removed,as well as particle accumulation patterns within the slurry chamber,identifying areas prone to clogging.Furthermore,the study examines cutterhead torque and thrust requirements for each design,providing a comprehensive performance assessment.Results demonstrate variations in performance across the three types,with the conventional cutterhead exhibiting the highest muck discharge rate under the tested conditions,while atmospheric-pressure designs show a higher risk of clogging due to increased particle accumulation in specific zones.This work contributes to a more informed selection and design methodology for slurry shield cutterheads,enabling engineers to optimize designs for specific soil conditions and minimize the risk of clogging in challenging geological conditions. 展开更多

Smog chambers provide controlled environments for studying atmospheric processes.This study presents the design and characterization of a novel vehicle-mounted dual-reactor smog chamber,capable of simulating atmospheric oxidation processes in both indoor and outdoor settings.Developed at the Guangdong Provincial Academy of Environmental Science,this innovative system consists of two 8 m³ cylindrical fluorinated ethylene propylene Teflon reactors housed in a van semi-trailer.The reactors can independently operate under black lamp irradiation or solar radiation,allowing seamless transitions between controlled laboratory conditions and real-world outdoor scenarios.Comprehensive characterization demonstrates excellent performance in temperature control(within±0.5℃ between 25 and 35℃ for indoor experiments),rapid mixing(2-3 min),high light transmission(>88%at 300-950 nm)and low wall loss rates for gases(10⁻⁵-10⁻⁴min⁻¹)and particles(0.12-0.17 h⁻¹).Parallel experiments in two reactors yield consistent results,confirming the reliability of the system for comparative studies.Validation experiments,including toluene-NOₓ photochemical oxidation and α-pinene ozonolysis,showed strong agreement with box model simulations,demonstrating the chamber’s utility for investigating atmospheric chemical mechanisms and secondary organic aerosol formation.The dual-reactor design,combining mobility and adaptability,enables versatile and high-fidelity simulations of oxidation processes. 展开更多

Lithium-sulfur batteries(LSBs)represent a next-generation energy storage technology,but widespread applications are restricted by the shuttle of lithium polysulfides(LiPSs).The rational design of separators has been demonstrated to be one of the most efficient and cost-effective strategies to curb the shuttle effect,and tremendous research progress has been achieved.The efficiency of a separator depends on its interaction with LiPSs,which is governed by the surface energy and binding strength.Despite several review works that have been reported to advance the separators,most of them primarily focus on active material innovation and construction.The most crucial issues of surface binding energy have not been systematically reviewed,limiting the precise design of efficient separators.In this review,fundamentals related to surface energy and binding interactions with LiPSs are comprehensively analyzed and discussed.With surface binding and energy main lines,the advancements in separator engineering strategies are elaborately summarized and discussed.Moreover,techniques for evaluating affinity to LiPSs are thoroughly analyzed to avoid any ambiguities in measurement.Based on the research context,valuable research directions are suggested to construct efficient separators.This work provides guidelines to regulate the surface binding and energy of separators for high-performance LSBs. 展开更多

Single-atom catalysts(SACs)stand at the forefront of catalysis research,attributable to their distinctive electronic structure,maximized atomic utilization,and exceptional catalytic performance,making them highly promising for renewable energy and sustainable energy conversion applications.However,their complex design parameters—including metal active sites,coordination environments,and substrate interactions—pose significant challenges for traditional experimental and computational approaches.These limitations hinder the systematic understanding of structure-property relationships in SACs.Machine learning(ML)offers a powerful alternative,enabling rapid screening and rational design by uncovering hidden patterns in high-dimensional catalyst data.This review summarizes recent advances in applying ML to the design and discovery of SACs.First,we analyze and summarize the recent trends and representative works in ML applications for SACs research.Next,a systematic workflow is proposed to guide researchers through ML-assisted SACs discovery,from data engineering to model application.We then showcase ML's impact on critical catalytic reactions—CO2RR,HER,NRR,and ORR/OER—demonstrating its ability to uncover high-performance catalysts.Finally,we discuss challenges and future directions for integrating ML with SAC research,aiming to inspire innovative solutions and interdisciplinary collaboration.By bridging ML and catalysis,this review provides researchers with a practical roadmap to expedite the advancement of SACs. 展开更多
