文摘Textile electronics with extraordinary sensing capabilities holds significant potential in the Artificial Intelligence of Things(AIoT).However,little effort is paid to their mutual advantages of robust interfacial interactions,ultra-strong mechanical performance,and stability.Herein,we fabricate homogeneous and multifunctional core-shell macrofibers by integrating bridge-functionalized MXene/PEDOT:PSS conductive ink with aligned bacterial cellulose(BC).These resulting macrofibers feature mechanical properties(tensile strength of 433.2 MPa and the Young's modulus of 25.9 GPa),exceptional electrical conductivity(10.05 S cm^(-1))and durable hydrophobicity.Such superior robustness allows for the fabrication of the macrofibers woven into textile-based triboelectric nanogenerator(PKT-TENG)and shows an impressive high-performance of a maximum open-circuit voltage of 272.54 V,short-circuit current of 14.56μA and power density of 86.29 mW m^(-2),which successfully powers commercial electronics.As the proof-of-concept illustration,the macrofibers with durable hydrophobicity and high piezoresistive sensitivity are further employed for precepting diverse liquids that can simultaneously monitor their distinctive motion features via real-time resistance variation on the textile-based array.This work is expected to offer new insights into the design of advanced fibers with ultra-strong mechanical capabilities and high conductivity and provide an avenue for the development of textile electronics for high-performance sensing and intelligent manufacturing.

文摘The development of multifunctional electromagnetic wave-absorbing materials is essential for next-generation flexible electronics and intelligent protection systems.Herein,a novel three-dimensional porous MXene-based film integrated with metallic nickel nanoparticles(Ni-PMF)is designed and synthesized with the potential to address the urgent need for multifunctional electromagnetic wave-absorbing materials in next-generation intelligent systems.By using polystyrene spheres as sacrificial templates,a hierarchical porous architecture is constructed to prevent MXene nanosheet restacking,extend electromagnetic wave propagation paths,and optimize impedance matching.Simultaneously,uniformly distributed Ni nanoparticles introduce abundant heterogeneous interfaces,enhancing interfacial polarization and magnetic loss,which significantly improve electromagnetic wave attenuation.The Ni-PMF film achieves a minimum reflection loss of–64.7 d B and a broad effective absorption bandwidth of 7.2 GHz,covering the full Ku-band and outperforming most reported MXene thin film absorbers.In addition to superior electromagnetic wave absorption,the film demonstrates excellent electrothermal conversion and flexible strain-sensing capabilities,enabling integrated protection and real-time sensing functions.This multifunctional material offers promising potential for next-generation smart flexible electronic systems.

文摘In two-dimensional bilayer systems,twist-angle-dependent electronic and thermoelectric properties have garnered significant scientific interest in recent years.In this work,based on a combination of density functional theory and nonequilibrium Green’s function method,we explore the electronic and thermoelectric properties in blue-phosphorene nanoribbon-based heterojunction(BPNRHJ)with and without blue-phosphorene nanoribbon(BPNR)stack.Our calculations find that the electronic conductance and power factor can be strongly enhanced by the BPNR stack,and their enhancements can be further observed with the twist between the layers.The main reason for this is the electronic hybridization between the layers can provide new transport channels,and the twist can modulate the strength of interlayer electronic hybridization,resulting in extremely violent fluctuations in electron transmission and hence an enhanced power factor.While the phonon thermal conductance exhibits very low dependence on the layer stack and twist.Combining these factors,our results reveal that the thermoelectric performance can be greatly modulated and enhanced in twist bilayer BPNRHJ:the figure of merit will be over 2.5 in 4-4-ZBPNR@ZGNR-AA-8.8∘at 500 K.

文摘Mixed halide perovskites exhibit great potential as materials for the future generation of photovoltaic devices.Yet,their reaction to moisture remains uncertain,necessitating further exploration.While prolonged exposure to moisture can lead to degradation,it can also passivate traps at an optimal moisture level.Here,we use scanning probe microscopy to perform nanoscale moisture-dependent photovoltaic characterizations of open and compressed grain boundary(GB)structures of wide bandgap(FAPbI_(3))_(0.3)(FAPbBr_(3))_(0.7) perovskites.The investigation reveals a decrease in the potential barrier at compact GBs with increasing moisture levels,contrasting with the behavior observed in open GBs.Moreover,the photocurrent distribution over both samples proportionally increases when relative humidity(RH)is raised from 10%to 60%.Notably,following a 24-h exposure at RH 60%,the compact-GB sample demonstrates:i)a reduction in the density of charged trap states at GBs,ii)higher photocurrent,accompanied by a noticeable decrease in current hysteresis compared to the open GB sample,and iii)further enhancement in device efficiency and crystallinity compared to devices with open GBs.These findings suggest that optimizing humidity conditions in engineering the GB chemistry can enhance the optoelectrical properties of GBs,ultimately leading to improved device performance.

文摘With the increasing growth of online news,fake electronic news detection has become one of the most important paradigms of modern research.Traditional electronic news detection techniques are generally based on contextual understanding,sequential dependencies,and/or data imbalance.This makes distinction between genuine and fabricated news a challenging task.To address this problem,we propose a novel hybrid architecture,T5-SA-LSTM,which synergistically integrates the T5 Transformer for semantically rich contextual embedding with the Self-Attentionenhanced(SA)Long Short-Term Memory(LSTM).The LSTM is trained using the Adam optimizer,which provides faster and more stable convergence compared to the Stochastic Gradient Descend(SGD)and Root Mean Square Propagation(RMSProp).The WELFake and FakeNewsPrediction datasets are used,which consist of labeled news articles having fake and real news samples.Tokenization and Synthetic Minority Over-sampling Technique(SMOTE)methods are used for data preprocessing to ensure linguistic normalization and class imbalance.The incorporation of the Self-Attention(SA)mechanism enables the model to highlight critical words and phrases,thereby enhancing predictive accuracy.The proposed model is evaluated using accuracy,precision,recall(sensitivity),and F1-score as performance metrics.The model achieved 99%accuracy on the WELFake dataset and 96.5%accuracy on the FakeNewsPrediction dataset.It outperformed the competitive schemes such as T5-SA-LSTM(RMSProp),T5-SA-LSTM(SGD)and some other models.

文摘Reliable electricity infrastructure is critical for modern society,highlighting the importance of securing the stability of fundamental power electronic systems.However,as such systems frequently involve high-current and high-voltage conditions,there is a greater likelihood of failures.Consequently,anomaly detection of power electronic systems holds great significance,which is a task that properly-designed neural networks can well undertake,as proven in various scenarios.Transformer-like networks are promising for such application,yet with its structure initially designed for different tasks,features extracted by beginning layers are often lost,decreasing detection performance.Also,such data-driven methods typically require sufficient anomalous data for training,which could be difficult to obtain in practice.Therefore,to improve feature utilization while achieving efficient unsupervised learning,a novel model,Densely-connected Decoder Transformer(DDformer),is proposed for unsupervised anomaly detection of power electronic systems in this paper.First,efficient labelfree training is achieved based on the concept of autoencoder with recursive-free output.An encoder-decoder structure with densely-connected decoder is then adopted,merging features from all encoder layers to avoid possible loss of mined features while reducing training difficulty.Both simulation and real-world experiments are conducted to validate the capabilities of DDformer,and the average FDR has surpassed baseline models,reaching 89.39%,93.91%,95.98%in different experiment setups respectively.

文摘Flexible electronics is gaining prominence in modern technology,particularly in flexible displays,wearable electronics,and biomedical applications.Electrodes,as core components of flexible electronics,demand high conductivity,flexibility,and stretchability.However,traditional rigid conductive materials often generate interfacial slip with elastic substrates due to mismatched Young's modulus,adversely affecting device performance.Room-temperature liquid metals(LMs),with their high conductivity and stretchability,have emerged as ideal materials for stable and reliable flexible electronic devices.This review discusses the physical,chemical,and biocompatibility properties of LMs.Additionally,LM-based fabrication strategies including patterning and sintering for flexible electrodes are outlined.Applications in implantable medical devices,wearable electronics,and flexible energy storage are illustrated.Finally,the primary challenges and future research directions in LMs are identified.

文摘The structural,relative stability,and electronic properties of two-dimensional AsP_(2)X_(6)(X=S,Se)were predicted and studied using the particle-swarm optimization method and first principles calculations.We proposed two low energy structures with P312 and P-31m phases,both of which the structures are hexagonal in shape and show non-centrosymmetry for the P312 phase and centrosymmetry for the P-31m phase.According to our results,two structural phases are found to be stable thermally and dynamically.The P312 phase of AsP_(2)X_(6)(X=S,Se)are indirect semiconductors with band gaps of 2.44 eV(AsP2S6)and 2.18 eV(AsP2Se6)at the HSE06 level,and their absorption coefficients are predicted to reach the order of 10^(5)cm^(-1)from visible light to ultraviolet region,but the main absorption is manly in the ultraviolet region.The P-31m phase of AsP_(2)X_(6)(X=S,Se)exhibits metal character with the Fermi surface mainly occupied by the p orbital of S/Se.Remarkably,estimated by first principles calculations,the P-31m AsP2S6 is found to be an intrinsic phonon-mediated superconductor with a relatively high critical superconducting temperature of about 13.4 K,and the P-31m AsP2Se6 only has a superconducting temperature of 1.4 K,which suggest that the P-31m AsP2S6 may be a good candidate for a nanoscale superconductor.

文摘The electronic structure,elasticity,and magnetic properties of the Mn_(2)XIn(X=Fe,Co)full-Heusler compounds are comprehensively investigated via first-principles calculations.The calculated elastic constants indicate that both Mn_(2)FeIn and Mn_(2)Co In possess ductility.At the optimal lattice constants,the magnetic moments are found to be 1.40μB/f.u.for Mn_(2)FeIn and 1.69μB/f.u.for Mn_(2)CoIn.Under the biaxial strain ranging from-2%to 5%,Mn_(2)FeIn demonstrates a remarkable variation in the spin polarization,spanning from-2%to 74%,positioning it as a promising candidate for applications in spintronic devices.Analysis of the electronic structure reveals that the change in spin polarization under strain is due to the shift of the spin-down states at the Fermi surface.Additionally,under biaxial strain,the magnetic anisotropy of Mn_(2)FeIn undergoes a transition of easy-axis direction.Utilizing second-order perturbation theory and electronic structure analysis,the variation in magnetic anisotropy with strain can be attributed to changes of d-orbital states near the Fermi surface.

文摘Ultra-thin crystalline silicon stands as a cornerstone material in the foundation of modern micro and nano electronics.Despite the proliferation of various materials including oxide-based,polymer-based,carbon-based,and two-dimensional(2D)materials,crystal silicon continues to maintain its stronghold,owing to its superior functionality,scalability,stability,reliability,and uniformity.Nonetheless,the inherent rigidity of the bulk silicon leads to incompatibility with soft tissues,hindering the utilization amid biomedical applications.Because of such issues,decades of research have enabled successful utilization of various techniques to precisely control the thickness and morphology of silicon layers at the scale of several nanometres.This review provides a comprehensive exploration on the features of ultra-thin single crystalline silicon as a semiconducting material,and its role especially among the frontier of advanced bioelectronics.Key processes that enable the transition of rigid silicon to flexible form factors are exhibited,in accordance with their chronological sequence.The inspected stages span both prior and subsequent to transferring the silicon membrane,categorized respectively as on-wafer manufacturing and rigid-to-soft integration.Extensive guidelines to unlock the full potential of flexible electronics are provided through ordered analysis of each manufacturing procedure,the latest findings of biomedical applications,along with practical perspectives for researchers and manufacturers.

文摘Iron oxide nanoparticles(IONPs)with intrinsic peroxidase(POD)-mimic activity have gained significant attention as nanozymes.Reducing sizes of IONPs is the mostly applied strategy to boost their enzymatic activity due to their high specific surface areas.Herein,we synthesized a series of uniformly sized IONPs ranging from3.17 to 21.2 nm,and found that POD activity of IONPs is not monotone increased by reducing their sizes,with the optimal size of 7.82 nm rather than smaller sized 3.17 nm.The reason for this unnormal phenomenon is that electronic structure also had great influence on POD activity,especially at the ultrasmall size region.Since Fe^(2+)are with higher enzymatic activity than Fe^(3+),3.17 nm IONPs although have the largest specific surface area,are prone to be oxidized,which reduced their iron content and ratio of Fe^(2+)to Fe^(3+),and consequently decreased their POD activity.By intentionally oxidized 7.82 nm IONPs in air,POD activity was obviously reduced,illustrating electronic structure cannot be overlooked.At the larger sized region ranging from 7.82 to 21.2 nm,oxidation degree of IONPs is similar,and surface electronic structure had a negligible effect on POD activity,and therefore,POD activity is predominantly influenced by specific surface area.By using the optimized 7.82 nm IONPs,tumor growth was obviously inhibited,demonstrating their potential in cancer therapeutics.Our results reveal that the designing of nanozymes should comprehensively balance their influence of surface electronic structure and specific surface area.

文摘Two-dimensional Dion-Jacobson(DJ)perovskite has garnered significant attention due to its superior responsivity and operation stability.However,efforts are predominantly focused on discovering new organic spacer to synthesize novel perovskites,while material-form-associated light management,which is crucial for enhancing the photodetector’s efficiency,is largely overlooked.Herein,we introduced surface light management strategy into DJ-type perovskite system by synthesizing surface-patterned BDAPbBr4(BPB,BDA=NH_(3)(CH_(2))_(4)NH_(3))microplates(MPs)using template-assisted space-confined method,which was further elucidated by theoretical optical simulation.By leveraging surface-patterned MPs to enhance light absorption,the BPB-based photodetectors(PDs)achieved remarkable photoresponse in ultraviolet region,marked by a high on/off ratio(~5000),superior responsivity(2.24 A W^(-1)),along with large detectivity(~10^(13) Jones)and low detection limit(68.7 nW cm^(-2)).Additionally,the PDs showcased superior light communication and imaging capabilities even under weak-light illumination.Notably,the anisotropic nature of the surface-patterned MPs conferred excellent polarization sensitivity to the PD.These results represented the first demonstration of BPB perovskite in weak-light communication and imaging,as well as in polarized light detection.Our findings offer valuable insights into enhancing photodetector performance and optoelectronic applications through surface light management strategies.
