The efficient storage and application of sustainable solar energy has drawn significant attention from both academic and industrial points of view.However,most developed catalytic materials still suffer from insufficient mass diffusion and unsatisfactory durability due to the lack of interconnected and regulatable porosity.Developing catalytic architectures with engineered active sites and prominent stability through rational synthesis strategies has become one of the core projects in solar-driven applications.The unique properties of mesoporous silicas render them among the most valuable functional materials for industrial applications,such as high specific surface area,regulatable porosity,adjustable surface properties,tunable particle sizes,and great thermal and mechanical stability.Mesoporous silicas serve as structural templates or catalytic supports to enhance light harvesting via the scattering effect and provide large surface areas for active site generation.These advantages have been widely utilized in solar applications,including hydrogen production,CO2conversion,photovoltaics,biomass utilization,and pollutant degradation.To achieve the specific functionalities and desired activity,various types of mesoporous silicas from different synthesis methods have been customized and synthesized.Moreover,morphology regulation and component modification strategies have also been performed to endow mesoporous silica-based materials with unprecedented efficiency for solar energy storage and utilization.Nevertheless,reviews about synthesis,morphology regulation,and component modification strategies for mesoporous silica-based catalyst design in solar-driven applications are still limited.Herein,the latest progress concerning mesoporous silica-based catalysis in solar-driven applications is comprehensively reviewed.Synthesis principles,formation mechanisms,and rational functionalities of mesoporous silica are systematically summarized.Some typical catalysts with impressive activities in different solar-driven applications are highlighted.Furthermore,challenges and future potential opportunities in this study field are also discussed and proposed.This present review guides the design of mesoporous silica catalysts for efficient solar energy management for solar energy storage and conversion applications. 展开更多

It is well known that the kit completeness of parts processed in the previous stage is crucial for the subsequent manufacturing stage.This paper studies the flexible job shop scheduling problem(FJSP)with the objective of material kitting,where a material kit is a collection of components that ensures that a batch of components can be ready at the same time during the product assembly process.In this study,we consider completion time variance and maximumcompletion time as scheduling objectives,continue the weighted summation process formultiple objectives,and design adaptive weighted summation parameters to optimize productivity and reduce the difference in completion time between components in the same kit.The Soft Actor Critic(SAC)algorithm is designed to be combined with the Adaptive Multi-Buffer Experience Replay(AMBER)mechanism to propose the SAC-AMBER algorithm.The AMBER mechanism optimizes the experience sampling and policy updating process and enhances learning efficiency by categorically storing the experience into the standard buffer,the high equipment utilization buffer,and the high productivity buffer.Experimental results show that the SAC-AMBER algorithm can effectively reduce the maximum completion time on multiple datasets,reduce the difference in component completion time in the same kit,and thus optimize the readiness of the part kits,demonstrating relatively good stability and convergence.Compared with traditional heuristics,meta-heuristics,and other deep reinforcement learning methods,the SAC-AMBER algorithm performs better in terms of solution quality and computational efficiency,and through extensive testing on multiple datasets,the algorithm has been confirmed to have good generalization ability,providing an effective solution to the FJSP problem. 展开更多

High-entropy alloys(HEAs),which were introduced as a pioneering concept in 2004,have captured the keen interest of nu-merous researchers.Entropy,in this context,can be perceived as representing disorder and randomness.By contrast,elemental composi-tions within alloy systems occupy specific structural sites in space,a concept referred to as structure.In accordance with Shannon entropy,structure is analogous to information.Generally,the arrangement of atoms within a material,termed its structure,plays a pivotal role in dictating its properties.In addition to expanding the array of options for alloy composites,HEAs afford ample opportunities for diverse structural designs.The profound influence of distinct structural features on the exceptional behaviors of alloys is underscored by numer-ous examples.These features include remarkably high fracture strength with excellent ductility,antiballistic capability,exceptional radi-ation resistance,and corrosion resistance.In this paper,we delve into various unique material structures and properties while elucidating the intricate relationship between structure and performance. 展开更多

Spectral coherent combining(SCC)offers a powerful approach to increase output power and shorten pulse duration.Here,we comprehensively investigate SCC of two beams to achieve the high combining performance.The preliminary analysis indicates that incident spectra and the transition region of the combiner both affect the combining process.The simulation results show that optimizing the overlapping spectral range,the transition width and start wavelength of the combiner can achieve high combining efficiency and high pulse quality.Guided by the simulation results,we built a femtosecond laser system based on the SCC of two fiber amplifiers,achieving 96.9%combining efficiency and high-quality 42-fs pulses.To the best of our knowledge,this is the first time that high combining efficiency and high pulse quality have been achieved simultaneously in a fiber femtosecond laser system based on SCC.This study provides design guidelines for the high-performance combination of beams covering different spectral regions. 展开更多

The unsatisfactory kinetics of the cathode electrode material are the key factor hampering the achievement of double-high performance(both high energy and high power)in aqueous Zn-based batteries.In this work,an amorphous Co-doped Ni2B hollow microsphere has been successfully constructed by a controllable etching process using a bimetallic MOF precursor.The unique hierarchical hollow structure and amorphous phase can provide more accessible active centers,abundant channels and a shortened diffusion path for enhanced redox kinetics.Therefore,the obtained CNB sample exhibits an ultra-high capacity of 2173 F g-1(301.8 mA h g-1)at a current density of 1 A g-1and can still maintain an initial value of 87.0%when the current density increases to 10 A g-1,achieving outstanding rate performance of CNB.Furthermore,a CNB/GO-Zn aqueous zinc battery device is fabricated,which exhibits a high energy density of 454.7 W h kg-1at a high power density of 0.46 kW kg-1.In addition,the CNB/GO-Zn device can maintain 80.01%of its initial value at a current density of 6 A g-1after 6600 cycles,revealing outstanding stability.Meanwhile,the energy storage mechanism is explored using ex situ XPS spectroscopy and ex situ TEM mapping,demonstrating that the energy storage mechanism of the CNB/GO-Zn device involves a mixed process of the Faraday redox reaction of Co/Ni elements and the adsorption and desorption of Zn species.The CNB/GO-Zn soft-packed device can operate an electronic thermometer for over 8 hours after several seconds of charging time,revealing its outstanding application prospect. 展开更多

Cytokines exert powerful immunomodulatory effects that are critical to physiology and pathology in humans.The application of natural cytokines in clinical studies has not been clearly established,and there are often problems associated with toxicity or lack of efficacy.The key reasons can be attributed to the pleiotropy of cytokine receptors and undesired activation of off-target cells.With a deeper understanding of the structural principles and functional signals of cytokine-receptor interactions,artificial modification of cytokine signaling through protein engineering and synthetic immunology has become an increasingly feasible and powerful approach.Engineered cytokines are designed to selectively target cells.Herein,the theoretical and experimental evidence of cytokine engineering is reviewed,and the“supercytokines”resulting from structural enhancement and the“immunocytokines”generated by antibody fusion are described.Finally,the“engager cytokines”formed by the crosslinking of cytokines and bispecific immune engagers and other synthetic cytokines formed by nonnatural analogs are also discussed. 展开更多

Alginate capillary hydrogels seeded with differentiated cells can fill the lesion cavity and promote axonal regeneration after grafting into the injured spinal cord.Neural stem/progenitor cells(NSPCs)can potentially repair the spinal cord;however,effects of alginate hydrogels(AHs)on NSPCs remain unknown.In this study,we fabricated AHs cross-linked by Ca2+and seeded hydrogels with rat embryonic day 14 NSPCs.Immunocytochemistry and electron microscopy show that NSPCs survive,proliferate and differentiate into neurons in vitro within the capillaries.After transplantation into an acute T8 complete spinal cord transection site in adult rats,approximately one-third(38.3%)of grafted cells survive and differentiate into neurons(40.7%),astrocytes(26.6%)and oligodendrocytes(28.4%)at 8weeks post-grafting.NSPCs promote the growth of host axons within the capillaries in a time-dependent manner.Host axons make synapse-like contacts with NSPC-derived neurons within the hydrogel channels,and graft-derived axons extend into the host white and gray matter making putative synapses.This is paralleled by improved electrophysiological conductivity across the lesion and partial hindlimb locomotor recovery. 展开更多

Tourist preferences are important for the high-quality planning and design of recreation spaces.The famous scenic locale of West Lake in Hangzhou,China,is used as an example in this study.Based on multi-source data(e.g.,online comments,and tourist photographs),we used content analysis,kernel density estimation,and image semantic segmentation technology to determine the spatial distribution of tourists’landscape preferences.We analyzed these spatial sight characteristics from the viewpoint,sight distance,and perspectives.The results show that tourists’landscape preferences are mainly concentrated on landscape architecture for recreation.The viewpoints of these preferences are concentrated in the north-south embankmentdfar beyond that of the east-west embankment.The preferences also show a spatial sequence in terms of sight distance,and the best visual effect is the open platform at the north and south islands of Xiaoyingzhou.From the perspective of vision,the degree of spatial openness in the tourists’landscape preferences is proportional to the distance of vision;the two factors have a convergent relationship.The discussion of the characteristics of tourists’landscape preference and space sight creation in Xiaoyingzhou provides a reference for the quality improvement of island recreation space. 展开更多
