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

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

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

The pre-wetting of aggregate surface is a means to improve the interface performance of SBS modified asphalt and aggregate.The effect of pre-wetting technology on the interaction between SBS modified asphalt and aggregate was analyzed by molecular dynamics simulation.The diffusion coefficient and concentration distribution of SBS modified asphalt on aggregate surface are included.The simulation results show that the diffusion coefficient of the aggregate surface of SBS modified asphalt is increased by 47.6%and 70.5%respectively after 110#asphalt and 130#asphalt are pre-wetted.The concentration distribution of SBS modified asphalt on the aggregate surface after pre-wetting is more uniform.According to the results of interface energy calculation,the interface energy of SBS modified bitumen and aggregate can be increased by about 5%after pre-wetting.According to the results of molecular dynamics simulation,the pre-wetting technology can effectively improve the interface workability of SBS modified bitumen and aggregate,so as to improve the interface performance. 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

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

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

Introducing Ti2AlC particles into TiAl alloys can effectively improve their strength,but this can also lead to stress concentration at the interface,resulting in the reduction of ductility.Therefore,Mn is adopted to synergistically improve the strength and ductility of the Ti2AlC/TiAl composite through solid solution and interface manipulation.The first-principles calculation shows the Ti-Mn bonds are formed at the Ti2AlC/TiAl interface after Mn doping,characterized primarily by metallic bonds with some covalent bonding.This combination preserves strength while enhancing ductility.Then,Ti2AlC/TiAl-Mn composite is prepared.The Ti2AlC,with an average size of 1.6μm,is uniformly distributed within the TiAl matrix.Mn doping reduces the lamellar colony size and lamellar thickness by 25.1%and 27.4%,respectively.A small quantity of Mn accumulates at the boundaries of the lamellar colonies.The Mn content must be controlled to avoid segregation,which may negatively impact performance.The yield stress,ultimate compressive stress,fracture strain,and product of strength and plasticity of the Ti2AlC/TiAl-Mn composite have been increased by 5.5%,11.5%,10.4%,and 23.0%,respectively,compared to those of the Ti2AlC/TiAl composite.The enhancement in strength is due to the combined effects of grain refinement,solid solution of Mn,and twining strengthening.Grain refinement and twin strengthening also can reduce stress concentration and improve ductility.In addition,at the electronic level,the Ti-Mn bond formed at the interface is contributed to the improvement of ductility. 展开更多

Nanocomposite technology is an effective strategy to enhance the performance of capacitive deionization(CDI).However,the poor interfacial interactions between the nanofillers and matrices limit their further optimization and commercial application.Here,we developed an interface engineering strategy to prepare a high-strength and high-toughness fiber electrode based on holey reduced graphene oxide(HRGO)and carboxylated carbon nanotubes(CCNT)through introducing borate bonds as bridging interactions.The interface interaction between HRGO and CCNT is significantly enhanced by the formation of dynamic cross-linked borate bonds,which not only effectively preventπ-πstacking and construct hierarchical ion transport channels to enhance ion transport efficiency and reaction kinetics,but also significantly improve mechanical stability and long-cycle performance based on self-healing properties in the fiber electrode.This configuration showed remarkably enhanced desalination capacity(30.6 mg g-1)and higher desalination rate(6.12 mg g-1 min-1),with cycling performance exceeding 90%,which exceeds previously reported values.Density functional theory calculations further reveal the mechanism by which the nanocomposite interface affects the CDI performance.Based on this excellent performance,we established a recirculating desalination hydrogen production system consisting of multiple CDI units connected in series with a hydrogen production unit.This effective strategy opens a new way to optimize the nanocomposite interfaces and achieve efficient electrochemical reactions. 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

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

Ultra-fine sizes and high thermal stability are often mutually exclusive for nanocrystalline(NC)materials because the high grain boundary(GB)energy of nanograins provides a large driving force for grain coarsening.Alloying is a classical strategy for stabilizing the microstructure of NC materials.However,the stabilization effects of alloying on NC materials typically rely on the segregation of solute atoms at GBs,which imposes restrictions on the selection of possible alloy systems.In this study,it is revealed experimentally and corroborated theoretically that the interface energies can be continuously regulated by simply manipulating the alloy composition in simple solid-solution alloy systems,enabling the control of the ultra-fine sizes and thermal stability of the alloys without GB segregation.In a model system of NC Au(Cu)-SiO2films,the dissolved Cu in Au can be used as a very accurate tool to tailor the interface energies of NC Au(Cu)-SiO2film,leading to ultra-fine(below 2 nm)Au(Cu)nanoparticles with exceptional thermal stability.Such Cu-induced grain refinement and thermal stabilization effects are supported by interface thermodynamic calculations.This study thus provides an alloying stabilization strategy without GB segregation,which broadens the scope for developing thermally stable NC alloy systems. 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
