The advancement of modern optical imaging systems has generated a substantial demand for precision-engineered imaging components with complex functionalities.Despite various micro-nanofabrication techniques demonstrating significant advantages over traditional methods,critical challenges persist in achieving nanoscale resolution and freely designed intricate micro-optical structures.Femtosecond direct laser writing(FsDLW)emerges as a pivotal solution to these challenges,facilitating the fabrication of sophisticated architectures that transcend the diffraction limit through nonlinear multiphoton absorption.This technique processes exceptional capabilities,including extensive material compatibility,versatile micro-nanoscale fabrication,and true three-dimensional structuring.To date,FsDLW has been successfully employed in the manufacturing of diverse micro-optical imaging components.This review systematically elucidates the fundamental methodologies of FsDLW applicable to micro-optical device fabrication,alongside a comprehensive overview of the relevant material systems.Furthermore,recent advancements in micro-optical imaging devices and their emerging applications are critically assessed.Finally,we provide a prospective analysis of unresolved challenges and future research directions for imaging optical components. 展开更多

Cement stands as a dominant contributor to global energy consumption and carbon emissions in the construction industry.With the upgrading of infrastructure and the improvement of building standards,traditional cement fails to reconcile ecological responsibility with advanced functional performance.By incorporating tailored fillers into cement matrices,the resulting composites achieve enhanced thermoelectric(TE)conversion capabilities.These materials can harness solar radiation from building envelopes and recover waste heat from indoor thermal gradients,facilitating bidirectional energy conversion.This review offers a comprehensive and timely overview of cementbased thermoelectric materials(CTEMs),integrating material design,device fabrication,and diverse applications into a holistic perspective.It summarizes recent advancements in TE performance enhancement,encompassing fillers optimization and matrices innovation.Additionally,the review consolidates fabrication strategies and performance evaluations of cement-based thermoelectric devices(CTEDs),providing detailed discussions on their roles in monitoring and protection,energy harvesting,and smart building.We also address sustainability,durability,and lifecycle considerations of CTEMs,which are essential for real-world deployment.Finally,we outline future research directions in materials design,device engineering,and scalable manufacturing to foster the practical application of CTEMs in sustainable and intelligent infrastructure. 展开更多

Unlike conventional electrochromic devices,Zinc anode-based electrochromic devices(ZECDs)ensure excellent charge balance between the electrochromic layer and Zn anode during the coloring/bleaching by reversible metal deposition/stripping on the Zn anode.Meanwhile,the inherent potential difference between the metal anode and the electrochromic layer can drive the spontaneous coloration/bleaching of ZECDs,featuring energy retrieval functionality.This review discusses the working mechanisms,performance indexes of ZECDs,and the impact of material selection on ZECD performance.Furthermore,we comprehensively summarize the latest research progress of ZECDs in energy storage,smart windows,and multicolor displays.We argue that using high-transparency zinc mesh,additive manufacturing processes,and self-healing electrochromic materials can significantly advance the commercialization of large-area ZECDs.Finally,“electrode-free”device structures,renewable or replaceable electrolytes,and strategies to suppress zinc dendrites are prospected to overcome cost-effectiveness and lifespan issues of ZECDs.This review aims at enabling more efficient and advanced ZECDs for multifunctional applications. 展开更多

Nanometallic materials have attracted wide research attention in the fabrication of functional devices,including flexible electronics circuits and high-sensitive sensors.Sintering of nanometallic materials is generally thought as an effective technology for the functional manufacturing,and the controllable sintering of nanometallic materials and its major mechanisms have long been a challenge.Here,an ultrafast laser processing strategy for Ag nanoparticles(NPs)is achieved by modulating plasmonic.The excitation mode of plasmon can be designed by laser parameters,including polarization with a specific crystal size.The atomic-scale ultrafast dynamics are revealed for understanding the sintering process and design of the sintered structures.The non-equilibrium energy transfer between electron and lattice and dynamic evolution of pressure are proved to be the foremost driving forces on the motion of atomic structures.Through research of plasmonic-induced electric field enhancement and non-uniform deposition of heat and in-situ observation of relative transmittance,mapping from atomic-scale structure to micro behavior is established.Based on plasmonic modulation and processing of Ag NPs,a machine learning combined flexible gesture sensor with high recognition accuracy is displayed.This work expands the knowledge of interactions between lasers and nanometallic materials and provides a method for designing functional devices for a wide range of applications. 展开更多

Reversible modulation of the transmittance in electrochromic devices(ECDs)holds tremendous potential for energy-saving windows.The choice of electrolyte significantly influences the optical modulation,coloring response speed,coloring efficiency,and cycling stability of electrochromic devices.Moreover,traditional electrolytes are prone to instability under extreme temperature conditions,leading to device failure and severely limiting the widespread application of smart electrochromic windows.This study introduces LiCl water-in-salt electrolyte(WiSE)into tungsten oxide-based ECDs.LiCl WiSE exhibits wide-temperature tolerance and excellent ion conductivity.Therefore,the constructed tungsten oxide ECD demonstrates large optical modulation(76.2%@700 nm),fast response time(tc=2.0 s,tb=1.8 s),and high cycling stability(95.8%retention after 1000 cycles).Especially,it operates efficiently over a wide temperature range of-30~80℃.This research provides a new approach for electrolyte selection in the fabrication of high-performance,wide-temperature-tolerant ECDs. 展开更多

We demonstrate room-temperature negative differential resistance(NDR)and unsaturated magnetoresistance(MR)effects in germanium-based devices.Our findings indicate that the observed NDR primarily originates from the carrier injection effect induced by local impact ionization in germanium.As the magnetic field increases,the MR values exhibit an unsaturated behavior,increasing quadratically at low fields and transitioning to a linear increase at higher fields,reaching approximately 91%at 1 T.We attribute this large unsaturated MR to carrier inhomogeneity.The equivalent Hall electric field strength was used to characterize the degree of carrier inhomogeneity under magnetic fields:a larger equivalent Hall electric field strength indicates stronger carrier inhomogeneity and consequently a larger corresponding MR.The coexistence of excellent room-temperature NDR and large unsaturated MR in germanium-based devices(achieved by constructing electrodes at two edge positions on the semiconductor surface)enables the development of multifunctional devices. 展开更多

The vibration control performance of powered wearable devices(PWDs)directly affects the health and comfort of the wearer.Effective vibration isolation technology has become a fundamental aspect of next-generation wearable device design.This study proposes a highly integrated nonlinear stiffness metastructure vibration isolator design for PWDs to address vibration isolation requirements in such scenarios.In this paper,we systematically analyze and experimentally verify the static characteristics of the proposed metastructure vibration isolator through numerical analysis,analytical model and experimental methods,and deeply discuss its dynamic transmissibility characteristics.Among them,we analytically derive and calculate the cantilever beam oscillator of the metastructure vibration isolator and verify the numerical results.Utilizing the mode superposition method,we examine the variations in vibration transmissibility under different operating conditions and geometric parameters.Experimental results are consistent with the numerical calculation results and demonstrate that the isolator exhibits excellent vibration attenuation within the vibration isolation frequency range of 53-61 Hz,achieving a minimum vibration transmissibility of−38 dB.The metastructure vibration isolation system presented in this study successfully achieves the anticipated vibration suppression performance,offering a novel approach to vibration isolation design for PWDs. 展开更多

The rapid expansion of artificial intelligence has led to significant challenges in energy consumption and computational efficiency.To address these issues,the exploration and development of all-optical controlled(AOC)synaptic devices represents a promising leap forward in neuromorphic computing,offering potential solutions to the inherent limitations of traditional von Neumann architectures.AOC synaptic devices,utilizing exclusively optical signals to emulate bidirectional modulation of synaptic weights,bypass the complexity and additional energy costs associated with conventional electrical or electro-optical hybrid signals.This review articulates the underlying framework and fundamental motivations for studying AOC synapses,while systematically reviewing current research progress.We particularly highlight the synergistic relationships among physical mechanisms,material behaviors,and device architectures,as well as neuromorphic computing based on optical writing and optical erasing of information.By systematically interpreting these multidimensional correlations,we propose scalable and reproducible strategies for device design.This work will certainly herald a substantial direction of AOC synapses,providing an ideal platform for exploring neuromorphic computing for artificial intelligence. 展开更多

This study investigated the effects of deep cryogenic treatment(DCT)on hot isostatic pressed(HIP)beryllium for inertial devices,focusing on residual stress,microstructure,tensile properties,and dimensional stability.The findings revealed that during DCT,residual stress in beryllium increased gradually due to non-uniform volumetric contraction and mismatch stress,reaching a 59.9%increase from initial levels after 200 h of DCT.DCT led to significant grain refinement and an increase in dislocation density.In 200 h DCT-treated beryllium,geometric necessary dislocation(GND)density increased 17.9%,grain size decreased 12.3%,and therefore yield strength and tensile strength improved by 4.2% and 5.6%,respectively.The dimensional stability of HIP beryllium was significantly enhanced by DCT,and the improvement tended to increase with the duration of DCT.The cumulative size changes of beryllium after 200 h of DCT during both cold exposure and cold cycling decreased significantly by 86% and 50%,respectively,compared to those of HIP beryllium.Furthermore,the residual tensile strength and retention rate increased by 12.5% and 5.5%,respectively,after undergoing room-temperature creep at 100 MPa for 1000 h. 展开更多

Graphene quantum dots(GQDs)consist of nano-sized fragments of graphene,typically in the range of 1-10 nm in size,and are often synthesized under extreme conditions(oxidativeeductive cleavage,electrochemical shearing,and pulsed laser burning).Extremely small size and edge effects give GQDs a high specific surface area,abundant surface active sites,chemical stability,low toxicity,physiological stability,and tunable fluorescence properties.Thus,GQDs have been widely used in the field of energy,catalysis,environment,biology,and optics etc.However,the synthesis and application of GQDs in energy storage systems(ESSs)are still at an early stage and lack timely and up-to-date research progress.In view of this,we summarize and discuss the most recent progress of the application of GQDs and their derivatives in energy storage devices,with an emphasis on their roles in enhancing lithium/sodium/zinc-ion battery performance(e.g.,improving ion diffusion kinetics,suppressing dendrite formation,and stabilizing electrode-electrolyte interfaces),boosting solar cell efficiency through light absorption tuning and charge transport optimization,and elevating supercapacitor energy density via high surface area and pseudocapacitive contributions.Finally,reasonable suggestions for future challenges are presented. 展开更多

Addressing the urgent demands for intelligent,miniaturized,and efficient thermal management in modern electronics,alongside the energy and environmental constraints,the development of compact and high-performance cooling systems has become imperative.The electrocaloric(EC)effect,which enables reversible entropy and temperature changes in dielectric materials through electric-field-controlled polarization,offers distinct advantages including high efficiency,fast response,and ease of integration.This review outlines the thermodynamic principles and surveys the evolution of EC thermal management devices.Ceramic-based EC devices exhibit strong potential for high-power applications due to their high thermal conductivity and thermal stability,while polymer-based EC devices are suited for wearable and flexible integration because of their mechanical compliance and processability.This review further contrasts the design,actuation,and application profiles of these platforms.Despite notable progress,challenges remain in long-term stability,multi-physics coupling,miniaturized integration,and environmental adaptability.Advances in material understanding,device design,and intelligent system control will position EC technology as a key enabler of efficient,compact,and sustainable next-generation thermal management. 展开更多

Transition metal sulfides(TMSs)are widely recognized as promising catalysts for the oxygen evolution reaction(OER),yet their large–scale application is hindered by poor conductivity,severe aggregation and sluggish reaction kinetics.To address these issues,a ternary CoS2/FeS2/Ti3C2Tx hybrid is rationally constructed via a three–in–one strategy,which simultaneously achieves the support introduction,morphology modulation and heterojunction construction.Structural characterizations reveal a hierarchical architecture composed of 1D CoS2 nanorods,0D FeS2 nanoparticles and 2D conductive Ti3C2Tx nanosheets,wherein CoS2 and FeS2 form a distinctive 1D/0D heterojunction.Density functional theory calculations demonstrate that strong electronic coupling at the CoS2/FeS2 heterointerface accelerates electron transfer and optimizes the adsorption behavior of oxygen intermediates.Benefiting from the synergistic effects between the CoS2/FeS2 heterojunction and the conductive Ti3C2Tx support,the as–prepared CoS2/FeS2/Ti3C2Tx hybrid exhibits elevated conductivity,promoted dispersibility and accelerated reaction kinetics,thus resulting in markedly improved OER performance as compared to the control samples.Additionally,the CoS2/FeS2/Ti3C2Tx hybrid presents a remarkably low overpotential of 284 mV when used as the anode catalyst in a water–splitting device,demonstrating its outstanding applicability for overall water electrolysis.Overall,this work provides a viable strategy for engineering high–performance TMS–based electrocatalysts through heterointerface design and conductive support integration. 展开更多

We discuss recent progress in using machine-learning(ML)-enabled inverse design techniques applied to photonic devices and components.Specifically,we highlight the design of optical sources,including fiber and semiconductor lasers,as well as Raman and semiconductor optical amplifiers.Although inverse design approaches for optical detectors remain relatively underexplored,we examine optical layers,particularly metamaterial absorbers,as promising candidates for high-performance optical detection.In addition,we underscore advancements in inverse designing passive optical components,including beam splitters,gratings,and optical fibers.These optical blocks are fundamental in developing next-generation standalone optical communication systems and optical sensing networks,including integrated sensing and communication technologies.While categorizing various reported deep learning architectures across five paradigms,we offer a paradigm-based perspective that reveals how different ML techniques function within modern inverse design methods and enable fast,data-driven solutions that significantly reduce design time and computational demands compared with traditional optimization methods. 展开更多
