Metamaterials programmed with target rate-dependent mechanical properties are efficient platforms for realizing advanced functionalities.Yet,the loading rate-dependent mechanical property programming has received limited attention.Here,the“stair-building”strategy is employed in the rate domain by combining the bistability with viscoelasticity.An arbitrary target curve in the programmable space can be approximated by a“stair”built by two kinds of“bricks”.The“bricks”can be realized by a dual-bistable unit,constructed by two bistable structures in series.The dual-bistable unit can switch between two efficient stable phases without inducing changes in the global morphology.Such a unit exhibits N-shaped stress-strain curves at both efficient stable phases with different peak values,resulting in different heights of“bricks”.Moreover,the N-shaped curves have rate-dependent peak values,indicating that the heights of“bricks”change with loading rate.The“stair-building”strategy is realized by array-structured mechanical metamaterials based on dual-bistable units.Different stress-strain curves under various loading rates can be reprogrammed in the same piece of metamaterial by intentionally selecting the efficient stable phases of units.Besides,the rate effect of the metamaterial can also be tuned by reprogramming stress-strain curves under both low and high loading rates,respectively.This reprogrammable metamaterial is promising in smart vibration isolators and adaptive energy absorbers. 展开更多

Aqueous zinc metal batteries(AZMBs)are considered ideal ones for next-generation energy storage devices due to their high theoretical specific capacity and intrinsic safety.However,uncontrollable zinc dendrite growth,hydrogen evolution reaction(HER),and interface corrosion prohibit the commercialization of AZMBs.The deposition behaviors of Zn2+/Zn0 on metallic Zn surface can be effectively regulated by constructing artificial interphase layers(AILs)to control desolvation and ion/atom flux.In this work,the intrinsic mechanism and interface failure of Zn2+electrodeposition behaviors are initially revealed,providing a theoretical basis for interface issues.To address these problems,the design strategies from carbon materials,zincophilic alloys,and inorganic/organic compound layers provide an in-depth analysis of the relationship between material structure and performance,establishing a theoretical foundation for the development of programmable interface architecture.In light of practical application requirements,the future direction is envisioned and pioneered,aiming to promote the practical application process of AZMBs. 展开更多

Terahertz communication technology is envisioned as a promising candidate for the pivotal spectrum technology in future wireless communication networks.However,the limited penetration ability of terahertz waves makes line-of-sight(LoS)transmission indispensable,hindering the extensive application of terahertz communications.In this work,a novel liquid-crystal programmable metasurface(LCPM)is proposed for the first time,which can effectively achieve dual-broadband beam manipulation to improve link stability and extend coverage for terahertz communications in non-line-of-sight(NLoS)scenarios.The LCPM is operated in both the W band that covers 94 GHz and the D band that covers 140 GHz,corresponding to x-polarized and y-polarized wave incidence,respectively.Based on the proposed LCPM,realistic NLoS terahertz communication links are established and showcased.Communication measurements substantiate that the LCPM is capable of realizing extensive dynamic channel regulations and long-distance communications across both bands in various modulation schemes,supporting real-time high-speed video transmission.The experimental results validate the feasibility of employing the LCPM for terahertz wireless communications,paving the way for developing and implementing ubiquitous terahertz communication networks even with LoS blockage. 展开更多

Programmable metasurfaces have shown exceptional potentials in wireless communications due to their capability to manipulate electromagnetic(EM)waves dynamically and flexibly.However,the large-scale application and flexible deployment of programmable metasurfaces still face challenges of high communication capacity requirements and stringent energy constraints.Here,we report an ambient-energy-driven space-time-coding metasurface to address these issues.On one hand,the metasurface can achieve efficient space-frequency-division multiplexing manipulations by dynamically controlling multiple frequencies and the spatial propagation directions of reflection EM waves.On the other hand,the shared-aperture ambient solar energy harvesting capability and low power consumption characteristic of the metasurface enable it to be self-powered without relying on any external power supply.To demonstrate these remarkable features,a four-channel wireless communication system prototype is built using the programmable metasurface.Experimental results confirm that four distinct images can be transmitted to four user terminals simultaneously,independently,and in real time with remarkably low energy consumption per bit.Such innovative metasurface provides a simple and effective approach for integrating ambient energy harvesting,multidimensional microwave manipulation,and direct information modulation on a single physical platform,which will advance the wireless communications in cost-effectiveness,enhanced capacity,energy efficiency,and environmental friendliness. 展开更多

Ceramic 4D printing,which integrates dynamic deformation with additive manufacturing,demonstrates significant potential in intelligent manufacturing,on-demand shaping of complex structures,and multifunctional device development.Its core advantage lies in endowing materials with environmentally responsive dynamic deformation capabilities.However,current technologies still face limitations in responsiveness,reversibility,and mechanical performance.To address these challenges,this study proposes a programmable ceramic precursor system based on synergistic reinforcement of phase-separating hydrogels and shape memory polymers,combined with a nano-ceramic particle enhancement strategy.Using stereolithography 3D printing,high-precision fabrication of complex structures was achieved.By adjusting precursor composition,programming time,and structural thickness,the phase-separation kinetics-driven delayed recovery mechanism was elucidated,enabling precise control over recovery onset time.Furthermore,the thermal response mechanism of the precursor materials is explored,along with their potential for multi-shape transformation in biomedical applications,which is further extended to shape memory polymer systems.By employing a layered printing strategy,the autonomous reversible deformation of ceramic precursors is realized,providing new possibilities for specific applications. 展开更多

The intrinsic pressure framework,which treats self-propelling force as an external force,provides a convenient and consistent description of mechanical equilibrium in active matter.However,direct experimental evidence is still lacking.To validate this framework,here we employ a programmable robotic platform,where a single light-controlled wheeled robot travels in an activity landscape.Our experiments quantitatively demonstrate that the intrinsic pressure difference across the activity interface is balanced by the emerged polarization force.This result unambiguously confirms the theoretical predictions,thus validating the intrinsic pressure framework and laying the experimental foundation for the intrinsic pressure-based mechanical description of dry active matter. 展开更多

The von Neumann bottleneck in conventional computing architectures presents a significant challenge for data-inten-sive artificial intelligence applications.A promising approach involves designing specialized hardware with on-chip parameter tunability,which directly accelerates machine learning functions.This work demonstrates a continuously tunable mixed-kernel function physically realized within a van der Waals heterostructure.We designed and fabricated a MoTe2/MoS2type-Ⅱvertical heterojunction phototransistor,which exhibits a non-monotonic,Gaussian-like optoelectronic response owing to its unique inter-layer charge transfer mechanism.This intrinsic physical behavior directly maps to a mixed-kernel function combining Gaussian and Sigmoid characteristics.Furthermore,the hardware kernel can be continuously modulated by in-situ tuning of external opti-cal stimuli.The mixed-kernel exhibited exceptional performance,achieving precision,accuracy,and area under the curve(AUC)values of 95.8%,96%,and 0.9986,respectively,significantly outperforming conventional kernels.By successfully embedding a complex,adaptable mathematical function into the intrinsic physical properties of a single device,this work pioneers a novel pathway toward next-generation,energy-efficient intelligent systems with hardware-level adaptability. 展开更多

Programmable metasurfaces have garnered significant attention due to their exceptional ability to manipulate electromagnetic(EM)waves in real time,propelling the emergence of reconfigurable intelligent surfaces(RISs)as a transformative advancement in wireless communication for controlling signal propagation and coverage.However,conventional RISs often suffer from a limited operational range and spectral interference,hindering their practical deployment in wireless relay and communication systems.To overcome this limitation,we propose an amplifying and filtering RIS(AF-RIS)to enhance the inband signal energy and filter the out-of-band signal of the incident EM waves,thereby achieving RIS array miniaturization and improved anti-interference capability.Furthermore,each AF-RIS element features 2-bit phase control,significantly improving the array's beamforming performance.A meticulously designed4×8 AF-RIS array is presented by integrating the power dividing and combining networks,which substantially reduces the number of amplifiers and filters,drastically decreasing the hardware costs and power consumption.The experimental results demonstrate the powerful capabilities of the AF-RIS in beam-steering,frequency selectivity,and signal amplification.Thus,the proposed AF-RIS offers significant potential for critical wireless relay applications by improving frequency selectivity,expanding signal coverage,and minimizing hardware size. 展开更多

Neuromorphic machine vision systems have garnered substantial interest due to their potential for achieving autonomous control through real-time visual perception and processing.Two-dimensional materials offer a highly promising option for neuromorphic photodetectors due to their tunable electrical and optical properties,as well as their compatibility with heterogeneous integration.However,the fabrication of such devices often involves inefficient or expensive processes,limiting their widespread commercial adoption.To address these challenges,we develop a scalable 7,7,8,8-tetracyanoquinodimethane(TCNQ)-doped graphene oxide(p-GO)sensor by utilizing easily prepared graphene oxide as a substrate and employing a surface charge transfer doping strategy to modulate its charge state.This device exhibits a high and linearly tunable responsivity.By varying the applied bias voltage,the responsivity can be adjusted from 1.4 mA/W to 25 mA/W.With precise control over the photoelectric response at 76 levels,we establish a 3x3 array of p-GO sensors as programmable kernels for optical image edge processing and convolutional neural networks,achieving the impressive accuracy of up to 97.7%in letter recognition tasks.We anticipate that this work will significantly enhance the widespread adoption and commercial utilization of neuromorphic detectors. 展开更多

The rapid growth of distributed data-centric applications and AI workloads increases demand for low-latency,high-throughput communication,necessitating frequent and flexible updates to network routing configurations.However,maintaining consistent forwarding states during these updates is challenging,particularly when rerouting multiple flows simultaneously.Existing approaches pay little attention to multi-flow update,where improper update sequences across data plane nodes may construct deadlock dependencies.Moreover,these methods typically involve excessive control-data plane interactions,incurring significant resource overhead and performance degradation.This paper presents P4LoF,an efficient loop-free update approach that enables the controller to reroute multiple flows through minimal interactions.P4LoF first utilizes a greedy-based algorithm to generate the shortest update dependency chain for the single-flow update.These chains are then dynamically merged into a dependency graph and resolved as a Shortest Common Super-sequence(SCS)problem to produce the update sequence of multi-flow update.To address deadlock dependencies in multi-flow updates,P4LoF builds a deadlock-fix forwarding model that leverages the flexible packet processing capabilities of the programmable data plane.Experimental results show that P4LoF reduces control-data plane interactions by at least 32.6%with modest overhead,while effectively guaranteeing loop-free consistency. 展开更多

Rashba-enabled paired exciton vortices provide a promising platform for programmable phase textures in van der Waals excitonic devices.Here,we develop a predictive analytic onset theory for accessing paired bright-dark interlayer-exciton vortices in a finite MoS2/WSe2 disk under a perpendicular magnetic field.The field tunes the bright-dark detuningΔbd(B)=Eb(B)−Ed(B)through Zeeman effect,thereby driving the system into or out of the vortex-access regime.Rashba spin-orbit coupling supplies the angular-momentum-changing bright-dark mixing required for vortex formation,and projection onto the lowest vortex-active disk doublet yields a mass-resolved square-root entry threshold incorporating a finite-size confinement floor and a weak detuning-sign asymmetry.Full-disk diagonalization further reveals that the paired-vortex doublet remains spectrally isolated from the nonvortex single-mode sector only within a detuning-dependent spinor-core window associated with a finite-temperature coherence bound.Driven-dissipative complex Gross-Pitaevskii simulations demonstrate that this selected doublet survives under pump,loss,and interactions as a robust nonlinear attractor.Together,the analytic,spectral,thermal,and dynamical criteria establish magnetic control ofΔbd(B)as a practical route for accessing and stabilizing paired-vortex condensates in finite excitonic devices. 展开更多

Land use in arid and semi-arid regions has a substantial effect on climate,environment,and biodiversity,thereby projecting the spatiotemporal changes in land use and the subsequent effects.This study employed the locally calibrated Future Land Use Simulation(FLUS)model,which coupled system dynamics with cellular automata and integrated an artificial neural network algorithm and a roulette wheel selection mechanism.We projected future land use(2020–2100)dynamics of Lanzhou,a typical river valley city in Northwest China,under three different Shared Socioeconomic Pathway(SSP)scenarios(SSP1-2.6,SSP2-4.5,and SSP5-8.5).The simulation results were validated and subsequently reclassified using the International Geosphere Biosphere Programme(IGBP)system to produce a dataset suitable for driving climatic and environmental models.Under the SSP1-2.6 scenario,urban and built-up land expanded consistently,whereas irrigated cropland and pasture as well as grassland contracted continuously.Conversely,the SSP5-8.5 scenario was characterized by a contraction of urban and built-up land,and relative stability of irrigated cropland and pasture as well as grassland.The SSP2-4.5 scenario presented a more complex trade-off,where urban and built-up land and grassland increased first and then decreased,whereas irrigated cropland and pasture followed an opposite trajectory.A significant inverse relationship between urban and built-up land and irrigated cropland and pasture was observed under all scenarios,underscoring the fundamental spatial competition that prevailed in this land-constrained valley city.Furthermore,the negative correlation of grassland with urban and built-up land,coupled with the positive correlation of grassland with irrigated cropland and pasture under both the SSP1-2.6 and SSP5-8.5 scenarios,indicated an evolution from broad confrontation to intricate internal trade-offs within the urban–agricultural–ecological system.This study underscored the critical influence of regional topographic and hydrological constraints on land-use evolution in arid regions,providing guidance for water resource management and ecosystem protection in Lanzhou,with applications for sustainable land-use planning in other arid and semi-arid river valley cities. 展开更多

Thermo-responsive hydrogels based on poly(N-isopropylacrylamide)(PNIPAM)are promising candidates for soft actuation,yet their practical applications are often constrained by sluggish thermo-responsive kinetics and insufficient mechanical robustness.Herein,phosphotungstic acid(PTA),a tungsten-containing polyoxometalate,was incorporated to regulate the phase transition behavior and modulate a PNIPAM/P(AA-co-AM)bilayer hydrogel,in which the thermo-responsive PNIPAM layer serves as the actuator whereas the non-thermo-responsive P(AA-co-AM)layer provides mechanical support.By increasing the PTA content up to 4 wt%,the thermally induced deformation time of the PNIPAM layer was prolonged from 30 to 120 s,whereas the recovery time at low temperature was shortened from 120 to 60 min,thereby enabling programmable thermo-responsive kinetics.The thermal transition of the PTA-PNIPAM layer was effectively regulated by PTA,with the lower critical solution temperature(LCST)gradually increasing and tunable up to 42℃,accompanied by an improved thermal stability manifested by reduced mass loss at 150℃.Mechanical characterization demonstrated that the P(AA-co-AM)layer modulated the tensile properties of hydrogel networks,and the bilayer configuration significantly outperformed the pristine PNIPAM hydrogel.Benefiting from the synergistic effects of kinetic regulation and mechanical modulation,the bilayer hydrogel further exhibited multi-substrate adhesion and reversible deformation,enabling an underwater gripping demonstration.This work highlights a polyoxometalate-enabled strategy for simultaneously controlling thermo-responsive kinetics and toughening PNIPAM-based hydrogels,thereby advancing functional soft materials for actuation-related applications. 展开更多

The rapid expansion of data-intensive applications has highlighted the fundamental limitations of traditional CMOS-based von Neumann architectures,particularly in terms of power efficiency,latency,and flexibility.Spin logic devices utilizing spin-orbit torque(SOT)present a promising pathway for nonvolatile,low-power,and in-memory computing.By manipulating electric current inputs,SOT can alter the magnetization states or domains,enabling programmable logic functions.When combined with flexible electronics fabrication techniques,these spin logic devices can be adapted into flexible forms to cater to a wide range of applications,such as wearable electronics and human-machine interfaces.In this review,we first trace the evolution of spin logic devices and then explore the operational mechanisms behind various SOT-based devices.We systematically discuss both magnetic-field-assisted and all-electric-driven logic schemes.Additionally,we review recent advancements in flexible SOT logic devices focusing on fabrication methods,thermally assisted low-power switching,and the integration of logic functions on flexible substrates.Finally,we address the current challenges and prospects for SOT-based spin logic devices,emphasizing their potential for low-power,highly integrated,and flexible spintronic computing systems. 展开更多

Programmable RNA-cleaving DNAzymes(RCDs)represent a unique class of catalytic nucleic acids that couple molecular recognition with enzyme-like activity.While DNAzymes have traditionally been explored for targeted gene regulation,recent advances in nanotechnology have repositioned them as programmable biosensing modules with stimuli-responsive therapeutic potential.When integrated into metal-oxide scaffolds,DNA-framework architectures,or metal-organic frameworks,DNAzymes form hybrid platforms that create confined catalytic microenvironments,provide enriched cofactor availability,and facilitate microenvironment-responsive activation.These engineered systems can function as nanoscale biosensing modules that respond to pH,redox gradients,metal ions,or microRNA signatures and convert these biological cues into catalytic outputs.Beyond enhancing analytical performance,such platforms may also reshape tumor immunometabolism.Through the selective cleavage of metabolic or immune-regulatory transcripts,DNAzyme nanocatalysts can directly reprogram glycolysis,redox balance,oxygen tension,and mitochondrial activity,and these metabolic changes in turn alleviate immunosuppression and promote innate and adaptive immune activation.This review outlines the mechanistic foundations of DNAzyme catalysis,summarizes recent nanoengineering strategies that endow DNAzymes with programmable sensing and stimuli-responsive functions,and discusses how these systems bridge biosensing and catalytic immunometabolic functions.We conclude with perspectives on translational challenges and opportunities,endorsing programmable DNAzyme nanocatalysts as emerging preclinical platforms for biosensingguided immunometabolic intervention. 展开更多
