Herein, a lattice-matched 2D/3D NiS/CdIn₂S₄ (NiS/CIS) Schottky heterojunction is rationally designed for efficient dual-functional photocatalysis under visible light. Structural analyses confirm the uniform deposition of NiS nanosheets on octahedral CIS with a lattice mismatch below 5%, ensuring coherent interfacial contact. The optimal 3% NiS/CIS composite exhibits exceptional hydrogen and benzaldehyde production rates of 2636.4 and 2717.6 μmol g⁻¹ h⁻¹, respectively—representing enhancements of 39.7 and 38.0 times over pristine CIS. The catalyst also demonstrates remarkable stability, retaining over &gt;99.0% activity after six cycles. Mechanistic studies reveal that the Schottky junction facilitates spatial separation of photogenerated carriers: electrons migrate to NiS, prolonging charge carrier lifetimes and lowering the hydrogen evolution overpotential, while holes accumulate on CIS that facilitated phenylcarbinol adsorption to drive selective phenylcarbinol oxidation via a carbon-radical pathway.

To address these limitations, a novel double-hollow plasmonic nanoreactor (H-ZIS_v/Au-Ag) with a “Plasmonic Thermo-Cycling (PTC)” enhancement mechanism was prepared herein. The cocatalyst, Au-Ag hollow alloy particles (HAPs), was embedded within the hollow structure via sulfur vacancy-mediated strong interfacial coupling, which synergistically enhances light scattering/reflection and promotes directional charge transfer. Subsequently, the localized surface plasmon resonance (LSPR) of Au-Ag HAPs extends light absorption into the NIR region and generates an intensely enhanced local electromagnetic field, enabling efficient hot electron excitation and remarkable photothermal conversion. Notably, the optimized Schottky junction, plasmonic near-field enhancement, and dual-cavity confinement effect synergistically improve the performance of the photothermally assisted photocatalytic hydrogen evolution (PTHE) reaction. Under AM 1.5G illumination at without cooling water (WCW), the catalyst achieved a high hydrogen evolution rate of 18.08 mmol·g⁻¹·h⁻¹, which is 2.99 times greater than that of pristine H-ZIS_v. The catalyst also demonstrates excellent stability over 750 min and exhibits measurable NIR-driven activity at 800 nm.

Understanding the rate at which the interface attains the equilibrium, for surface tension measurements, after the formation of a new interface is of significant interest. Although surface tension is independent of dynamic viscosity, the time required for a new surface to form (equilibrium/relaxation time) is influenced by viscosity. The measured surface tension value is accurate only once these viscous effects have subsided. Therefore, the relaxation time represents the minimum surface age value achievable during the measurement process. We experimentally established the minimum surface age needed to measure the dynamic and static surface tension of a fluid with a specific viscosity using three widely used methods: the Pendant drop method, the Wilhelmy plate method, and the Bubble pressure method. We propose a guideline with a phase plot that helps to choose the most suitable method and the youngest achievable surface age for an accurate measurement, independent of viscous effects. This guideline enables users in diverse applications such as 3D printed clothing, spray paint, coating, etc., to accurately measure dynamic and static surface tension without being influenced by viscosity effects.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"709 ","pages":"Article 139929"},"PeriodicalIF":9.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146083731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report a melamine-assisted pyrolysis strategy to synthesize a series of rare-earth (RE = Ce, Gd, La) integrated FeCoNiMn high-entropy alloy nanoparticles encapsulated within N-doped carbon nanotubes.

Monodisperse oil in water droplets containing dissolved polymer(s) in chloroform are initially generated in a glass capillary microfluidic device using an aqueous continuous phase containing PVA.
