Herein, an in-depth investigation is conducted into the mechanisms of recrystallization and reverse single-crystallization induced by processing strain and dislocations. A recrystallization arrest strategy is proposed for Bridgman-cutting-polishing (BCP) derived Cu(111) wafers, guaranteeing the high single-crystallinity (96.6%) and flatness (0.81 nm) of epitaxy substrates. The thorough investigation has provided a comprehensive understanding of the effects of surface roughness on the orientation, proportion of adlayers, as well as transfer qualities of graphene films.

Here, the concept of reticular photoelectrochemical transistor (RPECT) is proposed and devised that can realize metaplasticity with biochemical modulation. Based on the ambipolar behavior of a metal-organic framework channel gated by a photosensitive hydrogen-bonded organic framework electrode, biochemically modulated positive/negative photoconductivity and metaplasticity with the typical features, e.g., the nonmonotonic enhanced depression effect region and the threshold sliding are achieved. Taking advantage of such unique properties, in-sensor preprocessing and in-memory computing are further implemented for efficient image recognition. This work realizes the aqueous metaplasticity by a new device of RPECT, which also introduces the biochemical modulation into image recognition, providing a perspective for future development of machine vision processing.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"657 1","pages":"e2504338"},"PeriodicalIF":29.4,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144478901","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}

Many electrode materials exhibit substandard ICEs (<90%) due to excessive formation of solid electrolyte interphase (SEI). Traditional strategies modifying SEI formation mainly focus on the generating process but often consume extra Li+ and yield limited improvements. Here, a strategy is introduced that targets the terminating process of SEI formation, usually impeded by interfacial parasitic reactions, to achieve ICEs exceeding 90%. Using TiO2 as a model electrode, it is demonstrated that equivalent chemical fluorination suppresses the parasitic reaction between phosphorus pentafluoride (PF₅) and surface hydroxyl groups (─OH), early terminating SEI formation. Interfacial analysis and theoretical simulations reveal that this approach reduces organic SEI formation while preserving the beneficial LiF-rich inner SEI layer. As a result, the fluorinated TiO2 anode exhibits an ICE of 92.1%, significantly higher than the 74.1% of pristine TiO2, without compromising other electrochemical performance metrics. Pouch cell tests confirm the practical applicability of the method. This work provides deep insights into mechanisms of terminating SEI formation and opens a new pathway for optimizing the battery performances through inherent SEI manipulation.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"6 1","pages":"e2508647"},"PeriodicalIF":29.4,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144478902","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}

Determining the minimal effective temperature for bacterial destruction is therefore critical. In this study, artificial reef-like manganese-doped Prussian blue (PBMn) nanoframes are developed as photothermal agents and physical cross-linkers to reinforce a phytic acid and cationic polymer network coating. This innovative deposition approach facilitates the creation of a gradient PBMn-enhanced phytic acid-cationic polymer (PC-PBM) coating, achieving a balance between effective photothermal antibacterial activity and reduced heat-induced collateral damage. When applied to a polyurethane (PU) substrate, the gradient PC-PBM coating exhibits excellent photothermal efficiency, biocompatibility, and tunable antibacterial activity. Gene transcriptomics analysis demonstrates significant downregulation of virulence genes and biofilm-forming genes in pathogens following PC-PBM treatment, confirming the antibacterial efficacy of the coating. Both in vitro and in vivo evaluations, including studies in an infected hernia model, underscore the coating's excellent anti-infection performance.

The challenge is, however, how to preserve the native activity of proteins upon device fabrication/operation in non‐native environments (solvents, organic/inorganic interfaces, and working temperatures/irradiations). Herein, a new vision to identify and design ancestral‐like fluorescent proteins (FPs) is proposed. Using ancestral sequence reconstruction (ASR) out of a large dataset (221) of the best modern FPs suitable for photon down‐conversion in bio‐hybrid light‐emitting diodes (Bio‐HLEDs) a historical‐genetic reconstruction (family tree) was obtained, identifying a possible common ancestral FP. This computationally designed protein is produced in bacteria, featuring outstanding photoluminescence quantum yields in solution (e.g., 90%/80% for green‐/red‐emitting forms) and a strong tendency to agglomerate in polymer coatings. This resulted in red‐emitting Bio‐HLEDs that outperformed the reference with ≈2‐fold enhanced stabilities. The resplendent green‐/red‐emission of ancestral‐like FP itself and its respective devices led us to coin this new protein as QuetzalFP. Overall, it is set in ASR as an effective concept to reshape protein‐optoelectronics allowing us to identify i) many interesting ancestral FPs for lighting and ii) QuetzalFP as stepping‐stone platform for protein engineering.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"148 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479133","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}

Yet, critical challenges persist, largely owing to the polysulfide (PS) anion shuttle and the instability of the lithium metal anode (LMA). Salt anions are indispensable in batteries, which influence the basic properties of bulk electrolytes (e.g., solubility, stability, and ion conductivity) and the electrode-electrolyte interphases. Apart from those, the intrinsic characteristics of anions are of particular importance in Li-S batteries, as PS anions are major active intermediates that directly determine the sulfur redox kinetics and reversibility. However, the anion regulation needs further investigated, especially according to the Li-S chemistry. In this regard, fundamental considerations are provided on the anion engineering of Li-S batteries. Through a comprehensive analysis, the electrochemical behaviors of anions are reviewed. Then, the recent works on anion regulation for cathodes and anodes are summarized. For sulfur cathodes, the PSs dissolution, adsorption, conversion kinetics, and pathway are discussed in detail. For LMA, the influence of anion on lithium diffusion kinetic, the formation of SEI, and the anticorrosion are summarized.
