In this work, SrAl2O4:Eu2+, Dy3+ (SAO) is synthesized via a combustion method and co-doped with La3+ or Tb3+ to tailor the afterglow properties. The resulting phosphors are embedded into different polymer matrices (epoxy resin, PMMA, PVA, PVP, and PDMS) to investigate the impact of the polymers on photoluminescence (PL) and evaluate the cooling performance of the PersL-polymer composites. The composites exhibited an emission centred at 520 nm, high luminance values (up to 3300 cd m−2), enhanced afterglow compared with bare powders, and high mid-infrared emissivity (ε8–14 µm = 0.84–0.89). The PL contribution is evaluated through the calculation of the re-emitted energy, accounting for 4–6% of the absorbed solar energy. Outdoor measurements under solar irradiation demonstrate temperature reductions of up to 5°C. The results highlight the role of polymer selection in balancing persistent luminescence and thermal performance: PDMS and epoxy resin provided enhanced afterglow properties, and PVP exhibited relevant radiative cooling behaviour due to its solar reflectance. This study demonstrates the potential of SAO-based composites as coatings combining persistent luminescence and passive radiative cooling for sustainable thermal management applications.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 21","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70686","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149356414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Engineered topographical patterns have been used to induce such defects in cell monolayers, mimicking natural biological phenomena. In this work, we investigate the effect of cell–surface adhesion on collective cell dynamics at a vortex integer topological defect imposed by a topographical ring pattern. Adhesion strength is controlled via surface functionalization with poly-D-lysine, fibronectin, or covalently bonded fibronectin, and quantified using atomic force microscopy. As surface chemistry is modified, cell morphology changes from irregular to spindle-like, and two distinct collective modes emerge: weakly adhered cells exhibit strong inward motion, while strongly attached cells move tangentially to the ring. Spindle-shaped cells exhibit higher nematic order and promote the emergence of two +1/2 topological defects in the monolayer. We further characterize collective cell dynamics by analyzing correlation lengths and demonstrate the scaling of number density fluctuations in cell systems.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 21","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149356861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The band alignment was also constructed based on Anderson's rule by using work function values extracted from secondary electron cutoff (SECO) measurements.

However, its aggregation and poor conductivity limit its catalytic activity. Consequently, researchers are exploring ways to improve the conductivity and density of electroactive edges of MoS2 through hybridization with akin advanced 2D materials. Here, reduced graphene oxide (rGO) nanosheets are added to a liquid-phase-exfoliated MoS2 dispersion to create drop-casting hybrid MoS2@rGO electrodes for HER. The findings reveal the formation of 1.1 nm-thick MoS2 bilayers, with the catalytic performance of MoS2@rGO dependent on the degree of graphene oxide reduction. The rGO moderate reduction prevents the MoS2 bilayers from restacking, improves conductivity, retains oxygenated groups that enhance interlayer spacing, and exposes more electroactive edges. When hybridized with rGO at an optimal reduction time, the resulting system outperforms pristine MoS2 bilayers by attaining the overpotential of ca. 70 mV at 10 mA cm−2 along with a Tafel slope of ca. 46 mV dec−1. This shows that MoS2 bilayers hybridized with rGO offer a promising method for enhancing the electrocatalytic efficiency of MoS2-based electrodes, expanding opportunities for future strain and defect engineering, and high-end twist-angle assemblies for hybrid 2D-material systems.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 20","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70639","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149258213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the perspective of deterministic material removal, conventional reactive ion etching (RIE) is inadequate to meet these stringent demands. Plasma-enhanced atomic layer etching (PEALE), which offers the dual modalities of thermally activated isotropic etching and low-energy ion-driven anisotropic etching, has emerged as an indispensable technology for addressing these critical processing bottlenecks. This review systematically surveys recent advances in both isotropic and anisotropic PEALE, with a primary focus on progress reported since 2020. It first introduces the underlying fundamentals of diverse PEALE mechanisms, followed by a comprehensive overview of their applications to Si-based dielectrics, GaN and III-V compounds, transition metal oxides/nitrides, 2D materials, and metallic thin films. Hardware innovations, including advanced plasma sources and tailored bias configurations, are then evaluated. Furthermore, this work elucidates the mechanisms governing surface roughness evolution during ALE. Finally, multi-process integration strategies, specifically hybrid RIE+ALE and atomic layer deposition (ALD)+ALE frameworks, are discussed before the article concludes with a forward-looking summary and outlook for the field.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 20","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70663","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149258022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrodynamic dust shielding (EDS) is an active mitigation technology that repels electrostatically charged dust particles using oscillating electric fields; however, most existing designs employ rigid metallic conductors that fracture due to cyclic fatigue when attached to flexible surfaces. Flexible EDS devices incorporating graphene-based nanoflake electrodes mitigate cracking but lack dielectric encapsulation, leading to electrical breakdown during high-voltage operation. Here, we introduce a thermoplastic encapsulation strategy using high-density polyethylene, polysulfone, and polyvinylidene fluoride to enhance dielectric reliability. Conductive networks are spray-printed onto thermoplastic substrates and melt-bonded to same-material coating layers, embedding the nanoparticle network within a thermoplastic laminate. Interfacial bonding is characterized through peel testing and scanning electron microscopy, while short-term stability is assessed via cyclic electromechanical bending, abrasion resistance, and vacuum dust-removal performance. Thermoplastic encapsulation suppresses permanent resistance shift measured after cyclic bending to <1% for PVDF devices (compared to ∼6.5% for uncoated controls) and reduces abrasion-induced resistance increases by up to ∼5x. Encapsulated devices operate stably up to 6.0 kVpp without dielectric breakdown, whereas uncoated devices fail near 2.0 kVpp. These results establish a processing-structure-performance pathway toward resilient and adaptable EDS technologies for lunar exploration.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 20","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70667","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149258873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the changes in the magnetic properties of cation-modulated manganite superlattices fabricated from a single manganite target by varying the oxygen partial pressure, resulting in the modulation of cation stoichiometry. Using superconducting quantum interference device (SQUID) magnetometry, we found that the magnetization in superlattices of cation-modulated manganites increased by up to 36.8 ± 0.4% relative to the volume-weighted average of the corresponding single-layer films. Polarized neutron reflectometry further revealed a larger average magnetic response in the shorter-period superlattice, consistent with the trend observed by SQUID magnetometry. This observation is consistent with the interface-related magnetic interactions between the layers. These findings point to an interface-driven route to enhance magnetization in cation-modulated manganite superlattices and show that the effect is tunable by altering the number of interfaces.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 20","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70672","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149258084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
