However, challenges such as dendrite growth and electrolyte corrosion severely limit the reversibility of zinc anodes. In this study, a 3D Zn architecture with hydrophilic-hydrophobic patterned surfaces is proposed for robust and stable anodes. The 3D architecture of Zn offers sufficient sites and space for zinc plating, the hydrophobic layer isolates Zn from water attack, and the hydrophilic layer facilitates the rapid transport of electrolyte ions. This unique design endows Zn with robust Zn stripping and plating behaviors, outperforming many recently reported Zn anodes. Notably, symmetric batteries with this Zn achieve 2500 h of stable cycling at 5 mA cm<sup>−2</sup>. In addition, Zn-ion capacitors with this Zn anode exhibit outstanding cycling stability, maintaining a capacity retention of 76% over 5000 cycles at 0.5 A g<sup>−1</sup>. This study highlights that the rational integration of multiple strategies can fully leverage their merits to achieve exceptional performance, thus offering a reliable solution for enabling stable and dendrite-free operation of metal batteries.","PeriodicalId":228,"journal":{"name":"Small","volume":"7 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144193147","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}

The structurally Q-C12 has a fluorescent quinazolinone moiety attached with two sulfur centers and two long alkyl chains. The structural uniqueness of Q-C12 for the presence of sulfur-based alkyl chain backbone makes it selective towards the detection of mercury (Hg<sup>2</sup>⁺) ions, followed by the scavenging from the aqueous system. It also shows its ability to detect and bind with diethyl chlorophosphate (DCP), a toxic stimulant for nerve agents, using its fluorescence efficacy. Each observation has been well studied using NMR, fluorescence, and DLS analysis. Further, Q-C12 behaves very effectively as an anti-yeast agent.

One critical property influencing ENM behavior is dissolution, the release of ions and molecules into surrounding media, which dictates their abundance, fate, and biological response. A decade ago, dissolution was recognised as pivotal in understanding ENM interactions with exposure media and assessing their potential toxicity. Since then, progress in this field has led to a deeper understanding of ENM surface chemistry and transformations, positioning dissolution as a key factor in achieving “Safety-by-Design” (SbD) for sustainable ENM applications. Early dissolution studies relied on batch and flow-through methods, such as dialysis, but recent advances have favored in situ techniques such as single-cell/single-particle inductively coupled plasma mass spectrometry (ICP-MS) and liquid-cell electron microscopy, enabling real-time dissolution measurements. Additionally, computational models can now predict ENM reactivity and stability, enhancing the understanding of dissolution behavior. This perspective critically examines these developments, highlighting computational approaches for their efficiency and scalability, and proposes a roadmap to integrate these insights with SbD goals for safer, sustainable nanotechnology applications.","PeriodicalId":228,"journal":{"name":"Small","volume":"8 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144193074","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}

The incorporation of unsaturated metal sites and Brønsted acidic µ-OH groups significantly improves NH<sub>3</sub> binding, while defect engineering introduces additional adsorption sites for increased capacity. Functional modifications, including anion insertion and hydroxyl group functionalization, further boost NH<sub>3</sub> adsorption capacity, even in cases of reduced surface area. Emerging MOF composites, such as metal halide-embedded and ionic liquid-loaded materials, demonstrate outstanding NH<sub>3</sub> capture performance due to synergistic effects and cooperative interactions.
