Electroencephalography(EEG)foundation models are increasingly used as general-purpose backbones for brain-computer interfaces(BCIs)by leveraging large-scale pretraining and task-specific adaptation.This review summarizes recent progress in EEG foundation models from three perspectives:datasets and task coverage,with emphasis on how generalization goals are operationalized by split protocols and concrete evaluation procedures;model design choices,including input construction and tokenization,masked pretraining objectives,and Transformer backbones for spatiotemporal modeling across heterogeneous channel layouts;and downstream adaptation,comparing linear probing,full fine-tuning,and parameter-efficient tuning,while clarifying the conditions under which each setting is most informative.We emphasize that reported gains are often protocol-dependent,as differences in task scope,preprocessing,training budget,and baseline selection can substantially affect comparability and the extent to which conclusions generalize.Finally,we outline future directions for EEG foundation models in BCI,focusing on standardized evaluation infrastructure,EEG-tailored modeling choices,and deployment-aware adaptation under real-world constraints. 展开更多

Stability of base-exposed backfill roof in underhand drift-and-fill mining is crucial for the safety of those working beneath.Given the commonly used primary-and-secondary mining sequence,interfaces are formed between adjacent filled drifts,which can weaken the integrity of the backfill roof.These interfaces also lead to two common drift layouts:aligned drifts and staggered drifts.However,less attention has been paid to the interfaces and the two drift layouts were not adequately distinguished in previous studies.In this paper,the interfaces between filled drifts were firstly considered to investigate the stability of backfill roof.Failure modes and strength requirements of backfill roof in aligned and staggered drifts are comprehensively investigated by FLAC3D,with a focus on considerations of varied shear parameters of the interfaces.Results show that failure modes in aligned drifts transition from block sliding to top caving,bottom caving or sloughing as the interface cohesion increases from zero to at least half of the backfill cohesion.Further increases in interface cohesion allow aligned drifts to behave as if there are no interfaces between them.The critical stability conditions of backfill roof in aligned drifts were mostly determined by the interface strength instead of the backfill strength.However,the stability of backfill roof in staggered drifts is barely affected by the interface strength.The outcomes are expected to provide references for mining engineers to optimize drift layouts and perform cost-effective backfill roof strength design at mines using underhand drift-and-fill mining method. 展开更多

SrTiO3-based thermoelectric ceramics show potential for high-temperature energy harvesting but face challenges from inefficient carrier transport and high thermal conductivity.This work presents a multi-scale structural engineering strategy to address these challenges,fabricating textured Sr0.875La0.1Ti O3m Ti/10 wt%Bi2O3(SLTTB)ceramics via plate-like SrTiO3templates.Through this design,the ceramics form a unique core-shell architecture,where template seeds act as growth cores for epitaxially alignedoriented grains,forming coherent interfaces with a precipitate-rich interlayer and a precipitate-free shell.In the interlayer,uniformly distributed“peanut-shaped”Bi-Ti_nO2n-1nanoparticle pairs enhance electron mobility and phonon scattering.The hierarchical microstructure creates multiscale coherent interfaces that reduce electron grain boundary scattering,enabling preferential electron transport pathways parallel to the casting direction.This architecture enables the decoupling of electrical and thermal properties,with a power factor reaching 1815μW/m/K2at 1073 K with thermal conductivity suppressed by interfacial and nanoparticle scattering.Consequently,the SLTTB textured ceramic achieves a notable ZT of 0.64 at 1073 K,a significant enhancement over conventional counterparts.This work demonstrates a multi-scale structural strategy integrating template-induced texture,core-shell design,and nanoscale interface modulation to decouple the electrical and thermal properties of SrTiO3-based materials,and provides a roadmap for tailoring the electrical-thermal transport properties of thermoelectric textured ceramics. 展开更多

Lithium metal serves as an outstanding anode material,providing a high theoretical capacity of 3860 mA h g-1and a low reduction potential of-3.04 V vs.Li+/Li relative to the typical hydrogen electrode.All-solid-state lithium-metal batteries demonstrate exceptionally high energy density within power battery technology.The existing inorganic solid-state electrolytes(SSEs),including oxides,sulfides,and halides,demonstrate particular interactions with lithium metal.This study categorizes nine inorganic solid-state electrolytes(SSEs)according to their electrochemical behavior with lithium metal electrodes during the deposition and stripping cycles of lithium-symmetric cells into three classifications:(1)unrestricted reaction and failure,(2)dendritic growth and short circuit,(3)self-limiting decomposition and passivation.Concentrating on the third category of solid-state electrolytes(SSEs),we investigate the complex Li|Li3-5x-3yTaxLayCl3|Li system,particularly examining the performance of the Li|Li0.233Ta0.217La0.559Cl3(LTLC)|Li cell,which demonstrates stable cycling for more than 7000 h at a current density of 0.2 mA cm-2/0.2 mA h cm-2after a pre-fabrication resting period of 60 h.In situ X-ray photoelectron spectroscopy analysis semi-quantitatively elucidates the interfacial redox hierarchy in LTLC,indicating a more rapid reduction rate of Ta5+with lithium metal compared to La3+.The byproducts at the interaction are identified as well.X-ray Computed Tomography research revealed that the interfacial layer created during the pre-fabrication process is homogeneous,unlike that produced during a 6-h fabrication time,underscoring the importance of pre-fabrication in interfacial layer development.This technology enables the discovery of halide solid-state electrolytes that demonstrate advantageous interactions with lithium metal and the selection of interfacial products that enhance the stabilization of the battery system.This study serves as a significant reference for examining the compatibility of solid-state electrolytes with lithium metal and offers insights to inform future research. 展开更多

Li2CO3 was introduced into LiPF6-based electrolytes and the electrolytes were stored at 40°C.Nuclear magnetic analysis of electrolytes and X-ray diffraction characterization of reaction residues demonstrate the formation of LiPO2F2 and LiF during storage.This reformulated electrolyte boosts lifespan and Coulombic efficiency(CE)in Li||Li and Li||Cu cells,with Li||Li cells stably cycling for>800 h and 300 h at 0.5 mA/cm2 and 1.0 mA/cm2,respectively.Moreover,with the optimal content of Li2CO3,the CE of the reformulated electrolyte(91.56%)is greatly improved compared to that of the standard electrolyte(81.99%).The compatibility and enhanced rate performance of the reformulated electrolyte are also exhibited in Li||NCM full cells with a moderately high mass loading of 9.6 mg/cm2. 展开更多

Carbazole derivatives with a single phosphonic acid(PA)group are widely used as monolayer interfaces in perovskites and organic solar cells(OSCs).However,their hydrophilic nature renders ITO electrodes hydrophobic,limiting further applications.In this study,a novel carbazole-based compound functionalized with two PA groups,denoted 2PACz-D1,was designed to create a dual hydrophilic interface.This configuration enables the formation of a bilayer hole-transporting layer(HTL).Specifically,one PA group anchors to the ITO electrode,while the other generates a secondary hydrophilic surface.This allows the subsequent deposition of hydrophilic PEDOT:PSS,forming a protective bilayer HTL that shields ITO from corrosive acidic polymers.The OSCs incorporating this bilayer HTL achieved a power conversion efficiency of 19.44%and exhibited improved thermal stability compared to devices with a single HTL.This work demonstrates the potential of bis-PA carbazole derivatives for tailoring the HTL surface properties,offering promising opportunities for various organic electronic devices. 展开更多

Owing to the dispersion and multi-mode characteristics,guided wave non-destructive technology is promising for characterizing the interface state of incompressible viscoelastic multilayered soft plates.To effectively apply the guided waves in structural health monitoring,it is essential to attain a comprehensive understanding of dispersion and attenuation properties for Lamb waves in these plates,particularly those with weak interfaces.To achieve this,a hyper-viscoelastic fractional order model is employed to investigate Lamb waves in multilayered soft plates with weak interfaces.The analysis encompasses weak connections in both shear and vertical directions.An improved Legendre polynomial method with analytical integration expressions is employed to solve dynamic equations.The influence of weak interfaces,fractional order,and pre-deformation on wave characteristics is studied.Interestingly,results reveal the appearance of the transverse quasi-resonance for the S0 mode when pre-compression deformations reach sufficiently large magnitudes.Furthermore,phase velocity and attenuation variations are nonlinear as the weak interface coefficients increase.As these coefficients become adequately large,the variations diminish progressively,ultimately approaching a saturation point. 展开更多

Prelithiation is effective for compensating active lithium-ion(Li+)loss in silicon(Si)-based battery electrode materials.However,owing to the dynamic growth of the solid electrolyte interface(SEI),capacity fading remains the biggest challenge for the industrialization of Si electrodes.To address this problem,a novel ether-based prelithiation reagent was rationally designed by exploiting the weak solvent-solute coordination and the competitive reduction mechanism among electrolyte components.Precise regulation of the Li+solvation structure enhanced Li+transport during prelithiation,achieving an exceptional initial Coulombic efficiency(ICE)of~100%for the Si/carbon(Si/C)anode after performing contact prelithiation for 2 min.Furthermore,the lithium fluoride(LiF)-rich interface with high mechanical toughness was pre-formed to assist in the formation of a stable SEI controlling the lowest unoccupied molecular orbital(LUMO)energy and binding energy of the prelithiation reagent,thereby improving the half-cell cycle performance.Consequently,the ICE of the full-cell incorporating the prelithiated Si/C anode increased by 40%compared with that containing as-received materials,and the corresponding energy density was 551.2 Wh kg-1 based on the electrode material after 3 cycles.Furthermore,theoretical calculations combined with in situ characterization techniques confirmed the strong potential of the contact prelithiation design strategy for large-scale industrial applications. 展开更多

This study integrates true triaxial hydraulic fracturing experiments with finite-discrete element method(FDEM)numerical simulation to systematically investigate the control mechanisms of interface strength and inclination angle on hydraulic fracture propagation in coal measure strata under different in-situ stress conditions.The results indicate that the fracture propagation path at the rock interface is jointly controlled by the interface strength coefficient(η),the interface inclination angle(θ),and the vertical stress difference coefficient(κ).When fractures propagate from soft rock to hard rock,the interface strength coefficient(η)plays a dominant role.The larger the η is,the more likely the hydraulic fracture is to penetrate the interface along the direction of vertical stress.Conversely,when fractures propagate from hard rock to soft rock,vertical stress primarily controls the propagation path.A larger vertical stress difference coefficient promotes interface crossing,while a smaller coefficient tends to cause the fracture to extend laterally along the interface.The interface inclination angle influences the magnitude and direction of the vertical stress component along the interface.A smaller θ facilitates interface penetration by hydraulic fractures,whereas a larger θ leads to fracture propagation along the interface.The complexity of the hydraulic fracture network increases with higher κ and θ.Moreover,the complexity of hydraulic fracture morphology exhibits a non-monotonic trend,initially decreasing and then increasing with rising κ and θ.This research provides an important theoretical basis for the design and control of hydraulic fracturing in coal measure strata. 展开更多

CO2methanation technology has shown great application prospects in carbon neutrality and hydrogen storage due to its extremely high energy efficiency and potential economic benefits.It is highly desirable but challenging to design novel catalyst and achieve efficient and stable CO2methanation under mild conditions.Herein,we developed a highly active electron-enriched Y2O3/Ni catalyst,achieving a stable operation with~80.1%CO2conversion and~100%CH4selectivity for 400 h at 0.1 MPa and 220℃,which was a 100℃lower than the conventional supported Ni-based catalysts.Structural characterizations confirmed that the Y2O3/Ni catalyst maintained dynamic redox changes and formed electron-enriched Y2O3-x-Ni interfaces under reaction conditions.Mechanism studies proved that the Y2O3-x-Ni interfaces obviously lowered the energy barrier of*HCO dissociation,and shifted the rate-determining step from*HCO dissociation to*CO hydrogenation.Furthermore,profited by the moderate COx adsorption ability and higher H2coverage at the Y2O3-x-Ni interfaces,the*CO hydrogenation reaction was kinetically promoted.The above factors accounted for the excellent low-temperature CO2methanation activity of the Y2O3/Ni catalyst. 展开更多

The expansion of shale gas exploration into deeper reservoirs introduces increasing cementing challenges,primarily caused by cement sheath integrity failure through interfacial debonding.This study performed mechanical property characterization and interfacial bond strength evaluation of compositetoughened oil well cement to quantify the mechanical behavior of cement sheaths and cementing interfaces.Cavity pressure experiments were performed to obtain pressure-time curves of methane deflagrationfracturing under different fillingpressures.A whole-life-cycle well integrity model was established using a phased modeling approach,with the measured pressure data as input loads,and the cohesive zone model(CZM)was applied to simulate interfacial debonding evolution.Parametric analysis focused on the effects of perforation section length,deflagrationparameters(peak pressure,duration),and cement formulations on interfacial debonding.Numerical results reveal that the casingcement interface exhibits longer axial debonding lengths than the cement-formation interface,while the latter experiences faster debonding propagation.Sensitivity analysis highlights that composite toughened cement sheaths with reduced elastic modulus and enhanced bond strength significantly enhance wellbore integrity under methane deflagration.Interfacial debonding can be mitigated by optimizing perforation section length in staged fracturing operations and carefully controlling deflagration peak pressure and duration.This work enables predictive analysis of cement sheath debonding development and integrity evaluation,offering practical strategies for optimizing methane deflagration fracturing operations. 展开更多

Cutaneous haptic interfaces have demonstrated substantial potential in human-machine interaction,enabling applications such as immersive experiences,robotic teleoperation,and sensory transfer in prosthetics.By conveying rich haptic cues such as indentation,stretching,vibration,and temperature,cutaneous feedback improves presence,realism,task performance,and the stability of two-way interaction loops.This article introduces the fundamental concept of cutaneous haptic interfaces and reviews recent advances in cutaneous feedback modalities and device paradigms from skin-integrated patches to fingertips and whole-hand wearable devices.It highlights progress in spatiotemporal programmability for each feedback modality,as well as in combined multimodal feedback.Cutaneous adaptability designs for haptic feedback devices are also discussed,with an emphasis on maintaining natural interaction and achieving personalized haptic feedback.In addition,the integration of haptic feedback devices with sensing units has emerged as a popular trend,facilitating closed-loop control for more accurate and stable haptic interaction.Finally,the article concludes by underscoring a complete workflow spanning coordinated visual-haptic sensing,encoding,rendering,and feedback to support dexterous haptic interaction and enable more lifelike,responsive,and dependable performance in virtual or teleoperation scenarios. 展开更多

Fully implanted brain-computer interfaces(BCIs)are preferred as they eliminate signal degradation caused by interference and absorption in external tissues,a common issue in non-fully implanted systems.To optimize the design of electroencephalography electrodes in fully implanted BCI systems,this study investigates the penetration and absorption characteristics of microwave signals in human brain tissue at different frequencies.Electromagnetic simulations are used to analyze the power density distribution and specific absorption rate(SAR)of signals at various frequen-cies.The results indicate that lower-frequency signals offer advantages in terms of power density and attenuation coeffi-cients.However,SAR-normalized analysis,which considers both power density and electromagnetic radiation hazards,shows that higher-frequency signals perform better at superficial to intermediate depths.Specifically,at a depth of 2 mm beneath the cortex,the power density of a 6.5 GHz signal is 247.83%higher than that of a 0.4 GHz signal.At a depth of 5 mm,the power density of a 3.5 GHz signal exceeds that of a 0.4 GHz signal by 224.16%.The findings suggest that 6.5 GHz is optimal for electrodes at a depth of 2 mm,3.5 GHz for 5 mm,2.45 GHz for depths of 15-20 mm,and 1.8 GHz for 25 mm. 展开更多

With the growing global energy demand and the pressing need for a clean energy transition,supercapacitors(SCs)have demonstrated significant application potential in electric vehicles,wearable electronics,and renewable energy storage systems owing to their rapid charge-discharge capability,exceptional power density,and prolonged cycle life.The improvement of their overall performance fundamentally depends on the synergistic design of electrode materials and electrolyte systems,as well as the precise regulation of the electrode-electrolyte interface.This review focuses on the key components of supercapacitors,systematically reviewing the design strategies of high-performance electrode materials,outlining recent advances in novel electrolyte systems,and comprehensively discussing the critical roles of interfacial reinforcement and optimization in enhancing device energy density,power performance,and cycling stability.Furthermore,interfacial engineering strategies and innovations in device architecture are proposed to address interfacial degradation in flexible SCs under mechanical stress.Finally,key future research directions are highlighted,including the development of high-voltage and wide-temperature-range electrolyte systems and the integrated advancement of multiscale in situ characterization techniques and theoretical modeling.This review aims to provide theoretical guidance and innovative strategies for material design,contributing toward the realization of next-generation supercapacitors with enhanced energy density and reliability. 展开更多
