The built‐in electric field at heterojunction interfaces further promotes charge carrier migration and improves surface reaction kinetics. To leverage these synergistic effects, this study employs a combined approach involving sulfidation, phosphidation, and electrodeposition to achieve P‐doping and construct a heterojunction layered structure. Specifically, P‐doping is implemented through a phosphorization treatment of NiCo<jats:sub>2</jats:sub>S<jats:sub>4</jats:sub> grown on nickel foam, followed by the electrodeposition of CoZn‐layered double hydroxide (LDH) onto the honeycomb‐like NiCo<jats:sub>2</jats:sub>S<jats:sub>4</jats:sub> substrate. Density Functional Theory calculations demonstrate that this unique structural design markedly enhances the composite's electrical conductivity and optimizes the adsorption energy of OH<jats:sup>−</jats:sup> ions, leading to significantly improved ion/electron reaction kinetics.

This study employs vibrating solid surfaces to decouple and investigate the effects of inertia, ion-slipping, and electrostatic interactions at the molecular scale. This approach reveals \"inertial layer\" in the initial liquid strata, which plays a critical role in governing interface dynamics. Within this layer, a tunable Helmholtz zone is identified, where mechanical stiffness and electrostatic forces adjust in response to ion concentration. Beyond this lies a Debye screening region characterized by repulsive forces and electrostatic decoupling from the double-layer capacitor model. Using phosphate-buffered saline (PBS) as a model electrolyte, it is demonstrated that low ionic strength enhances interfacial stability, while high concentrations increase electrostatic repulsion, influencing nanoscale mechanical behavior. These insights refine the understanding of interfacial phenomena and hold significant implications for biosensing, catalysis, and energy storage technologies.","PeriodicalId":228,"journal":{"name":"Small","volume":"139 1","pages":"e2505067"},"PeriodicalIF":13.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144748142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attached droplets on the Janus wire transported along the periphery avoided clogging and enhanced the performance.

This approach enables localized self-assembly of spark discharge-synthesized sub-10-nm Pt and Al nanoparticles on patterned substrates. Precise control over Pt film morphology (porosity) through modulation of spark power and carrier gas flow rate is demonstrated. Porous Pt layers lead to diffused Pt/Al interfaces, which become sharper for densely packed Pt layers. On ignition, the self-sustained high-temperature alloy formation reaction wavefronts are recorded. The bimetallic interface strongly influences the Pt/Al reaction kinetics, with three orders of magnitude faster reaction speeds for sharper interfaces. Porous morphologies and hence diffused interfaces are hindered by excessive air gaps and premixed regions, intermediate porosities achieved speeds of 0.012 m s-1, and dense morphologies have sharp interfaces with minimal air pockets reaching speeds up to 6 m s-1.

By quantitative investigations of diameters as well as lifting speed of large bubbles, it ensures that convective boiling heat transfer mechanism dominates without forced convection, accounting for constant heat transfer coefficient at high-heat-flux regions. Force analyses are adopted to investigate the individual micro bubbles that form the bubble blanket, which is pinned downside to nano-ridge surfaces by free energy while pulled upside by merging effect of buoyancy-driven large bubbles. The presence of the bubble blanket facilitates the removal of large bubbles by modifying the surface tension distribution, sustaining safe boiling heat transfer across a broad range of heat fluxes.
