In this work, we report a commercial Celgard separator engineered with pearl-like nanospheres (Celgard@PNS) to enable electrochemically stable and dendrite-free lithium metal anodes (LMAs). The PNS-functionalized layer in the Celgard@PNS ensures rapid and homogeneous Li ion flux, which stabilizes LMAs and effectively mitigates dendritic Li deposition. Moreover, the PNS modification fosters the development of a robust solid-electrolyte interphase (SEI) layer. The Celgard@PNS-based Li||Cu half-cell exhibits stable Coulombic efficiency for 110 cycles, and the corresponding Li||Li symmetric cell sustains long cycling stability (&gt;900 h) at a high current density of 10 mA cm<sup>−2</sup> with an areal capacity of 1 mAh cm<sup>−2</sup>. Impressively, when paired with a high-mass-loading NCM811 cathode (22.5 mg cm<sup>−2</sup>), the Li||NCM811 full cell retains 81.4 % of its initial capacity after 140 cycles at 0.5 C. These results underscore the potential of the Celgard@PNS separator for practical implementation in high-capacity LMBs.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"71 1","pages":"163688"},"PeriodicalIF":6.7,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183827","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}

In this study, a series of Mn-based catalysts were synthesized via a hydrothermal method, followed by modulation of surface oxygen vacancies through the adjustment of the roasting atmosphere, and were subsequently applied in the catalytic combustion of toluene. Activity tests showed that the α-MnO<sub>2</sub> catalyst calcined under argon atmosphere had the best catalytic performance, which was able to achieve 90 % toluene conversion at 235 °C under a weight hourly space velocity (WHSV) of 120,000 mL·g<sup>−1</sup>·h<sup>−1</sup>. In addition, the catalyst also maintained high toluene removal efficiency at 248 °C, even when the WHSV was increased to 150,000 mL·g<sup>−1</sup>·h<sup>−1</sup>. Characterization results demonstrated that oxygen vacancies on the catalyst surface can be effectively regulated by modifying the roasting atmosphere. The introduction of oxygen vacancies enhanced the low-temperature reduction ability and oxygen mobility of catalysts, thus improving the catalytic performance. Besides, higher Mn<sup>3+</sup>/Mn<sup>4+</sup> and O<sub>ads</sub>/O<sub>latt</sub> ratios were also critical factors for high activity.

Herein, a novel ceramic-based coating with superior mechanical properties and exceptional tribological performance has been developed via the introduction of carbon and resin within the inherent defects of thermally sprayed YSZ coatings. The results demonstrate that carbon and resin were precisely introduced into the micro- and nanoscale pores and cracks within the YSZ coatings by in-situ synthesis and vacuum impregnation processes. The filling of these defects substantially contributes to the enhancement of the microhardness, fracture toughness, and cohesive strength of YSZ coating. Furthermore, the introduction of carbon and resins triggers the formation of a robust and self-lubricating film during sliding process. Consequently, this leads to a substantial reduction in the friction coefficient by approximately fourfold, to about 0.31, and a considerable decrease in the wear rate by around four hundredfold, to about 6.895 × 10<sup>−6</sup> mm<sup>3</sup>/(N·m).

Here, we report design and fabrication of ITO metasurface to concentrate UV– visible light (∼350 nm to 550 nm) in the quasi near field. ITO metasurfaces in form of square patches measuring 1.3 µm on each side, with thickness of 120 nm, and a periodicity of 2 µm were fabricated using femtosecond laser-based direct writing. The periodic arrangement of ITO patches facilitate the formation of electric field hotspots in the quasi near field due to the constructive interference of the diffracted light and guided mode resonance. We incorporated these metasurfaces onto ZnO quantum dots-based UV photodetectors, which exhibited about 183 % enhancement in the photoresponsivity due to the enhanced light-matter interactions.
