In view of the frequent deterioration of molten steel quality during the tundish filling process,the slag-steel-air interface behavior in a tundish,including liquid level fluctuation,slag eyes,slag entrapment and air suction during the steady-state casting and filling process,was comparatively studied through physical modeling and mathematical simulation methods.During the filling process,the liquid surface forms a large-size slag eye under the impact of molten steel from a ladle shroud,which simultaneously results in a violent fluctuation of liquid level.Concurrently,the liquid flow entrains the air phase and the cover slag into the tundish impact zone,resulting in slag entrapment and air suction.At filling flow rates of 1.5Q,2.0Q,and 2.5Q(Q is the flow rate under steady-state casting),the amount of slag entrapped is 8.39×10-5,9.65×10-5,and 12.7×10-5m3,respectively,while the volume of air aspirated is 0.84×10-4,1.47×10-4,and 2.01×10-4m3,indicating that slag entrapment and air suction intensify with an increase in tundish filling flow rate.Flow field characterization identifies eddy currents in the impact zone as the primary driver of the above phenomena.Proper filling process parameters were proposed to improve the steel quality during the tundish filling. 展开更多

For decades,refining grain or twin structures at the nanoscale has been the cornerstone strategy for enhancing metal strength[1].However,when structural dimensions shrink to below~10 nm,this approach hits an insurmountable bottleneck,that is,material softening triggered by interface instability,which prevents further strength improvement[2-5].Now,writing in science,Li and colleagues introduce a novel strengthening approach based on nanoscale negative excess-energy interfaces(NEIs)that elevates the mechanical performance of nickelmolybdenum(Ni-Mo)alloys to an unprecedented level[6]. 展开更多

We derive closed-form solutions to the three-dimensional Eshelby's problem of a spherical Eshelby inclusion undergoing uniform deviatoric eigenstrains concentrically embedded in an isotropic elastic finite spherical domain with a traction-free or rigidly clamped boundary.The interface between the inclusion and its surrounding domain is assumed to be of Steigmann-Ogden type.Our solutions indicate that the stresses and strains within the spherical inclusion are generally nonuniform because of the effects of the finite spherical domain and the Steigmann-Ogden imperfect interface.The internal elastic field of stresses and strains is uniform within the spherical inclusion when a condition that relates the single interface parameter to the geometric parameter and Poisson's ratio of the finite domain is satisfied.When the spherical edge is rigidly clamped,a GurtinMurdoch interface is found to be sufficient to achieve this interior uniformity property.In contrast,when the spherical edge is traction-free,a Steigmann-Ogden interface with nonzero and positive bending stiffness parameters must be used to achieve the interior uniformity property. 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

While 2D/3D heterostructures are widely employed to improve the stability of perovskite optoelectronic devices,their effectiveness is fundamentally governed by the crystallinity of the interfacial structure -a factor often overlooked.Disordered interfaces exhibit thermodynamic metastability,where ion diffusion induces sequential phase transitions from low-n to high-n phases.Here,we construct atomically ordered 2D/3D interfaces using phase-pure 2D perovskite capping layers,which reduce the interfacial phase transition rate by 95%and effectively suppress ion migration.As a result,devices exhibit outstanding operational stability,retaining over 99%of their initial power conversion efficiency after 1500 h of continuous operation,along with excellent thermal durability at 85℃.These findings identify interfacial order as a critical parameter for regulating ion dynamics and phase behavior,providing a robust design principle for achieving high-efficiency,long-lifetime perovskite technologies. 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

The dual interfaces of the perovskite layer,especially the interface between perovskite and selfassembled monolayer(SAM),play a crucial role in ensuring good efficiency and stability of solar cells in p-i-n configuration.However,it is still challenging to simultaneously modify the dual interfaces using a simple technology without additional processes,particularly for large-area perovskite solar modules(PSMs).In this work,we propose an in situ dual-interface modification method that introduces 5-aminovaleric acid hydroiodide(5 AVAI)as a bifunctional molecular interface spacer,which has an anchoring carboxyl group for orientation and an amino group for interface modification.We demonstrate that 5 AVAI modifies the SAM layer through oriented anchoring,improved wettability,and strengthened interactions with perovskite and charge transport layers.Notably,the extrusion of 5 AVAI during the perovskite crystallization process passivates surface defects and mitigates surface lattice strain.Using this bifunctional molecular interface spacer,we achieve the champion efficiency of 22.31%(certified21.69%)for 10 cm×10 cm PSMs with an aperture area of 64 cm2by slot-die coating.Moreover,the corresponding module exhibits exceptional stability,maintaining 95.6%of its initial efficiency after 2000 h of continuous maximum power point operation at 75℃,which is among the best operational stabilities for PSMs. 展开更多

Weak rock-concrete interfaces significantly affect the stability of underground supporting structures.This study aims to investigate the effects of interface inclination on the creep behavior and failure mechanisms of composite specimens.Seven rock-concrete composite specimens with different inclination angles under hydrothermal curing at 60℃were prepared,and uniaxial and graded loading creep tests were completed.The results show that with increasing interface inclination,the compressive strength of the composite specimens initially decreases and then increases,with the minimum strength observed at inclinations between 60°and 75°.Three typical failure patterns were identified:axial failure,composite failure,and interface failure.The creep failure strength exceeded the uniaxial compressive strength,indicating improved time-dependent deformation resistance under elevated temperature curing.The instantaneous strain initially decreases and then increases as the interface inclination angle grows.Compared to 0°inclination,specimens with 45°,60°,75°,and 90°inclinations exhibited reductions in instantaneous strain of 2.64%,18.84%,23.29%,and 0.73%,respectively.The steady-state creep rate and creep ratio exhibited a decrease-stabilization-increase trend with increasing stress levels.Creep strain increased with increasing stress levels for all inclinations,with a sharp increase near the failure stage.A nonlinear constitutive model considering interface inclination and creep damage was developed based on damage theory.A nonlinear damage-based constitutive model incorporating interface inclination effects was developed,and its theoretical predictions closely matched the experimental data in all creep stages.These findings provide a quantitative understanding of creep failure mechanisms in rock-concrete interfaces and provide practical references for enhancing the safety of underground support systems. 展开更多

In the realm of large-scale power system energy storage,sodium-based batteries represent a cost-effective post-lithium energy storage technology,making inorganic solid-state sodium batteries(ISSSB)a critical branch of this development.Inorganic solid-state electrolytes(ISSEs)are the core components of sodium batteries;however,they face significant challenges such as insufficient ionic conductivity,interfacial instability,and dendrite growth,all of which severely hinder practical application.This review critically assesses experimental protocols and theoretical frameworks related to mainstream ISSEs and systematizes optimization strategies aimed at overcoming these challenges.Leveraging integrated insights from both experimental and computational studies,the review first categorizes and summarizes the primary types of ISSEs,namely oxide-,sulfide-,and halide-based electrolytes.It then details interfacial optimization strategies focused on addressing three core interfacial issues:ion transport barriers resulting from mechanical incompatibility,side reactions stemming from electrochemical mismatch,and dendrite formation.Finally,the review advocates prioritizing in-depth research that integrates experimental and theoretical approaches to establish a closed-loop methodology encompassing predictive design,multiscale investigation,mechanistic exploration,and high-throughput automated experimentation,with feedback-driven refinement.This work serves as a comprehensive reference and systematic roadmap for future research on solid-state electrolytes(SSEs). 展开更多

This paper investigates the “brush-like”deformation phenomenon of the contact interface at the bolt-hole during the interference-fit installation of high-locking bolts under static loading in CFRP connection structures.An innovative theoretical model is proposed to predict axial installation force,specifically designed for moderate interference-fit.This model is based on the “brush-like”deformation of the hole wall,with the axial installation force predicted through force analysis and theoretical calculations,effectively overcoming the limitations of prior models that idealized the contact interface at the bolt-hole.The predictions generated by this theoretical model align closely with experimental data,confirming its efficacy in accurately forecasting the curve of installation force for interferencefit bolts during the static installation within the moderate interference-fit range.Additionally,a comprehensive analysis of the relationship between deformation of the hole wall and curves of installation force across small,moderate,and large interference-fit levels are presented.It is demonstrated that the degree of deformation within the moderate interference-fit range is more suitable than that in the small and large interference-fit ranges,making it a reliable alternative for installation force tests within this range during static installation.The moderate interference-fit domain[1.00%,1.24%]is established as a validated and optimal range of interference-fit bolts for the static installation. 展开更多

The phase composition at the slag-iron interface and the distribution behavior of titanium,vanadium,chromium and silicon between hot metal and Ti-bearing electric furnace slag were thoroughly explored.The basicity range for the anosovite phase region was defined by using a phase diagram and a minimum smelting temperature was set at 1540℃.Thermodynamic calculations demonstrate that the activities of TiO2 and SiO2 in the slag decrease with increasing basicity,while those of V2O3 and Cr2O3 increase.Similarly,the activities of[Ti]and[Si]in the molten metal decrease,while those of[V]and[Cr]rise with increasing basicity.As basicity increases,the distribution ratios,LTi and LSi decrease,whereas LV and LCr increase.Significantly,the recovery efficiencies of vanadium and titanium are improved with higher basicity.The primary phases identified in the slag include anosovite,diopside,and titanium spinel.However,when the basicity exceeds 0.8,the formation of the perovskite phase becomes less favorable,suggesting that basicity should be maintained at or below 0.8. 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

Stress represents a critical determinant of dynamic hazards in underground coal mining operations.Heterogeneous geological features substantially influence stress distribution and magnitude throughout mining environments.To investigate the mechanical evolution and failure mechanisms of heterogeneous stratified composite coal-rock(CCR)under mining-induced stresses,three-point bending tests(TPBT)and numerical simulations are conducted on CCR specimens with varying homogeneity indices.Results show a significant positive correlation between CCR fracture strength and the homogeneity index(φ).Higher φ values are associated with more uniform displacement discontinuity zones during the fracturing process.Initial loading is observed to induce compressive strain at the upper coal-rock interface(UI),while tensile strain predominated at both the lower interface(LI)and boundary(LB).Interface strain magnitudes followed the pattern LB>LI>UI,with stability inversely proportional to strain intensity.As φ increases,interfacial stability is reduced,damage severity is amplified,and the critical strain energy release rate is elevated.These variations are primarily governed by the homogeneity-dependent redistribution of particle zones and the downward migration of resistant interfaces.These findings enhance our understanding of fracture propagation in heterogeneous CCR under mining stresses,thereby contributing to improved hazard forecasting and control strategies in coal mine composite roof systems. 展开更多

Artificial interface layer-aided zinc anodes(AIL@Zn)with simultaneously controllable Zn dendrite growth and corrosion resistance are highly expected to simultaneously achieve both high capacity and cycle stability in aqueous zinc ion batteries(AZIBs).However,how the facet effects of the AIL guides the efficient Zn deposition behavior remains an open question.Herein,we devise a facile and scalable hydrothermal approach to synthesize various nanostructured X-CeO2 AILs to coat the Zn anode,ultimately offering an X-CeO2@Zn electrode.Among all X-CeO2@Zn anodes,rod-shaped CeO2 with exposed{110}facets modified Zn anode(R-CeO2@Zn)can effectively inhibit dendrite growth and side reactions,thereby delivering ultrastable durability over 2500 h at 1 mA cm-2/0.5 mAh cm-2and reversibility cycled for 250 h at 84.7%depth of discharge.In addition,MoS2//R-CeO2@Zn full cell delivers a significantly capacity retention rate above 99%after 1000 cycles.The superior performance originates from the exposed{110}facets,which uniquely modulate the binding and diffusion energies of Zn adatoms to promote homogeneous deposition.This work shifts the AIL design principle from mere composition selection to atomic-level facet control,offering a general strategy for next-generation battery electrodes.Additionally,the strategy proposes its extension to other metal-ion battery systems. 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
