Here, we reported a peroxidase-based proximity labeling method to survey the proteome at the nanoparticle (NP)-cell interface. Horseradish peroxidase (HRP) was conjugated to a variety of NPs and other ligand types while still being able to biotinylate the proteins surrounding NP (or ligand)-receptor complexes. Using two NP-based tracers for macropinocytosis (MP), which is highly relevant to NP internalization, we performed a proteomic survey and revealed the interface proteome difference between traditional and receptor-dependent MP. Moreover, our survey found that E-cadherin (CDH1), while not serving as the primary receptor, is present at the NP-cell interface and is functionally important for the cellular uptake of a wide variety of NPs.

However, due to vanadium ions show relatively low solubility and are easy to precipitate at extreme temperatures, the battery suffers from the long challenge of low energy density and poor temperature adaptability. In this work, by introducing vanadium and bromine dual active species into the positive electrolyte, a novel V/V-Br redox flow battery (VBrRFB) is developed to boost the energy density and temperature window of vanadium-based flow batteries. The bromine, not only acts as the secondary redox couple to enhance the overall concentration of active species, but also disrupts the hydrogen bond network while optimizing the solvation structure of vanadium. As a result, the VBrRFB achieves an energy density of as high as 152.4 Wh L<sup>-1</sup><sub>catholyte</sub> (38.1 Wh L<sup>-1</sup><sub>catholyte+anolyte</sub>), which is 265.9% higher than traditional all-vanadium redox flow batteries, while maintaining stable cycling over 250 cycles with an energy efficiency of 82.5%. Additionally, the VBrRFB exhibited excellent stability and performance from -10°C to 50°C, with energy densities of 107.6 Wh L<sup>-1</sup><sub>catholyte</sub> at 50 °C and 88.8 Wh L<sup>-1</sup><sub>catholyte</sub> at -10 °C, demonstrating its strong potential for practical energy storage.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"116 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transition of metaoptics from the laboratory into applications is enabled by scalable production methods based on highly reproducible semiconductor process technology. Here, we introduce a method for the fabrication of double-sided metasurfaces through deep-UV lithography as a production-ready method for achieving high-quality metaoptics. We achieve patterning of a silicon wafer on both sides with mutual alignment of around 10 μm based on tool accuracy without requiring through-wafer alignment markers other than the wafer notch. An application highlighting the benefits of double-sided design is demonstrated in the form of a dual-band metalens with independent control over focal lengths in mid- and long-wavelength infrared bands. Using multireticle stitching, we demonstrate a 40 mm diameter, large-area metalens with excellent broadband imaging performance, showing partial canceling of chromatic dispersion when used in a hybrid configuration with a BaF<sub>2</sub> refractive lens. Our work establishes a production-ready approach to infrared metaoptics designs and double-sided metaoptics fabrication with direct potential for translation into scalable technology for real-world applications.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"98 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manganese dioxide (MnO<sub>2</sub>), a transition-metal oxide, existing in multiple polymorphs with distinct atomic frameworks and tunable defect chemistries, is an ideal compound to investigate structure–property–performance correlations. In this study, α- and β-MnO<sub>2</sub> nanorods were synthesized and systematically evaluated to elucidate the influence of the crystal structure, grain boundaries, and oxygen vacancies on the catalytic behavior. The β-MnO<sub>2</sub> phase demonstrated superior catalytic activity, which was attributed to its abundant high-energy grain boundary interfaces, and elevated concentrations of surface oxygen vacancies, as revealed by X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HRTEM) analyses. Phase-dependent structural features and surface defects modulate the Mn oxidation environment and generate unsaturated coordination sites that facilitate reactant adsorption and bond activation. These sites serve as highly active centers that promote reactant adsorption and bond activation, thereby enhancing the catalytic activity and substantially accelerating the combustion dynamics of composite solid propellants. These catalytic enhancements driven by structural modifications resulted in the accelerated decomposition of ammonium perchlorate (AP) and an enhanced burn rate in AP-based composite solid propellants.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"237 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314720","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}

During melting, Cr promotes the formation of (Cr, Co)₃Si primary phases, which contribute to the refinement of the initial grains. The addition of Cr significantly increases the activation energy for second-phase precipitation by 46%, thereby retarding the precipitation kinetics by raising the nucleation energy barrier. However, in the early stage of aging, the co-precipitation of BCC-Cr (three variants) and δ-(Ni, Co, Cr)₂Si results in a multi-phase strengthening effect, markedly enhancing the peak hardness. Cr promotes the transformation of δ-(Ni, Co)₂Si into the more stable δ-(Ni, Co, Cr)₂Si phase and induces the precipitation of fully coherent β-(Ni, Co)₃Si, significantly delaying over-aging and enhancing hardness retention. The formation enthalpies of δ-(Ni, Co, Cr)₂Si and β-(Ni, Co)₃Si are lower than those of δ-(Ni, Co)₂Si and β-Ni₃Si, indicating that the Cr-containing precipitates exhibit stronger thermodynamic driving force and higher structural stability after overcoming the precipitation activation energy. The effect of Cr on grain exhibits a pronounced time-dependent behavior: during short-term aging (2<!-- --> <!-- -->h), Cr suppresses the precipitation of secondary phases, thereby increasing lattice distortion (KAM value increases by 3.4%), promoting the formation of Cube recrystallization texture (1.82), and weakening the Brass texture (from 5.89 to 4.29). After prolonged aging (20<!-- --> <!-- -->h), the 0.5Cr alloy retains a high precipitate density through suppressed coarsening, strengthening grain boundary pinning. As a result, the Brass texture (1.92) is retained, and the recrystallization fraction (2.0%) remains significantly lower than that of the 0Cr alloy (23.6%), ultimately leading to a mixed microstructure composed of recrystallization textures (Rt-C: 1.70, R: 2.43) and deformation textures inherited from cold rolling.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"15 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314734","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}
