Among various production routes, water electrolysis stands out as a promising approach. However, the efficiency of hydrogen evolution reaction is limited by the adhesion of gas bubbles on electrode surfaces, which blocks active sites, increases overpotential, and limits mass transfer. This review highlights the design of micro/nanostructured array electrodes to achieve underwater superaerophobicity, reducing bubble adhesion, facilitating the nucleation and rapid release of ultrasmall bubbles, thereby contributing to reduce in overpotential, faster bubble growth, enhanced mass transport, and improved catalyst stability. We summarize recent advances in fabrication strategies of such electrodes, focusing on micro/nanostructural designs, covering from 0 to 3-dimensional structures. Additionally, the role of hydrophilic gels in optimizing superaerophobicity is discussed. Finally, challenges and future directions are addressed, including bubble dynamics accurate modeling, development of high activity and stability catalysts, intelligent adaptive electrode structure and active bubble regulation, and the integration of artificial intelligence and deep learning for guided electrode design. This review aims to provide a comprehensive perspective on how superaerophobic electrode design address bottlenecks in gas-evolving electrodes, paving the way toward more efficient and economical hydrogen production.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02198-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147809414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, simultaneously achieving high-sensitivity fluorescence thermometry and efficient space radiative cooling remains challenging, as enhanced visible absorption improves thermometric response but increases solar heating. Here, we address this trade-off through a material-structure co-design strategy by developing an Eu-doped ZrO<sub>2</sub> submicrosphere metacoating that integrates space radiative cooling with fluorescence-based temperature sensing. Guided by photonic-structure optimization using a constrained-gradient optimizer combined with grid-search mapping, the optimized metacoating, featuring a submicrosphere diameter of 0.756 µm and a volume fraction of 35%, achieves an ultralow solar absorptance (<i>α</i><sub><i>s</i></sub> = 0.076) and a high thermal emittance (<i>ε</i> = 0.931). In parallel, bandgap-driven compositional optimization identifies an optimal Eu content of 8.48%, enabling outstanding thermometric performance. The metacoating delivers a net cooling power of 323.69 W m<sup>−2</sup> and a 77 °C temperature reduction relative to an Al sheet, outperforming representative oxide-based inorganic coatings. It allows temperature sensing over 173–433 K with a maximum relative sensitivity of 0.797% K<sup>−1</sup>, surpassing fluorescent oxides with comparable absorption edges. Moreover, the metacoating maintains the lowest <i>α</i><sub><i>s</i></sub> and reliable irradiation resistance under proton, electron, atomic oxygen and ultraviolet exposures, outperforming reported counterparts. Together with its scalable fabrication, this work establishes a dual-functional metacoating platform for intelligent spacecraft thermal management that combines efficient radiative cooling with high-sensitivity fluorescence thermometry.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02195-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147754835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current therapeutics fail due to the incapabilities in adaptively modulating the metabolic bifurcation across the contradictory pathological contexts. Here, we address this challenge by developing a platinum (Pt) single-atom nanocatalyst (PtSNC) with microenvironments-selective multienzyme-mimicking activities to pioneer a bi-polar bioenergetic intervention strategy. In acidic and reduced nicotinamide adenine dinucleotide (NADH)-overexpressed tumor niches, it exhibits NADH oxidase (NOX)-, oxidase-, and peroxidase-like activities, depleting NADH reserves and generating highly reactive Pt = O species to disrupt energy metabolism and induce both apoptosis/ferroptosis. While it shows NOX-, catalase-, and superoxide dismutase-like activities in neutral diabetic wounds, rectifying hyperglycemia-induced cellular NAD<sup>+</sup>/NADH abnormity and bioenergetic disorder to revitalize the cells and tissues, with promoting angiogenesis and mitigating local inflammation to accelerate regeneration. Murine diabetic melanoma resection models demonstrate its extensive capacity in effectively eradicating residual tumor tissues and suppressing the recurrence, and promoting diabetic wound healing concurrently without systemic toxicity, making PtSNC a safe and potent nanotherapeutic for diabetic tumor postoperative therapy.

To address this, we engineered a novel chiral supramolecular biomaterial derived from L-/D-phenylalanine and D-phenylalanine (L/DP) with well-defined nanostructure and optical activity. L/DP achieved biomimetic integration and stereoselective regulating of integrin β1 (ITGβ1) in scar tissue. In vitro, LP suppressed fibroblast proliferation by downregulating ITGβ1 (72%), inhibiting FAK/PI3K/AKT signaling and TGF-β1. In vivo (rabbit ear HS model), LP reduced scar thickness (54%), collagen deposition (39%), and α-SMA expression (45%), outperforming conventional drugs by 23%. This chirality-directed strategy provides a drug-free, painless, and highly effective HS therapy via integrin-mediated remodeling of the scar microenvironment and holds substantial clinical promise.\u0000</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02180-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147735190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
