Tremendous progress is achieved in the past decades to clarify the underlying intrinsic relationships between various effects of catalysts and CO2RR performance from a micro‐level perspective. However, numerous studies indicate that all parts of electrocatalytic system construction will affect CO2RR performance, and closely relate to the ultimate industrial applications. To comprehensively cognize CO2RR, this review thus ventures to bridge this lacuna via casting a particular spotlight on this topic with a more comprehensive and in‐depth discussion. Taking holistic insights, beyond the micro‐level catalyst design, into the macro‐level components and system constructions toward CO2RR (e.g., electrolyzer design, electrode assembly, electrolyte, and membrane selection), with an emphasis on discussing their merits and drawbacks, applicable environments, encountered difficulties, and challenges, to identify their feasible applications, and understanding their inherent connections between each other, as well as their intrinsic relationships with CO2RR performance.

However, conventional metal‐based electrodes exhibit severe mechanical mismatch with soft brain tissue, often resulting in insertion‐induced micro‐damage and chronic inflammation. While polymer‐based alternatives offer improved mechanical compliance, their inherently low electrical conductivity limits performance. Here, a soft microelectrode array composed of vertically‐aligned carbon nanotube (CNT) forests that uniquely combine high electrical conductivity (≈41.24 kΩ at 1 kHz) and mechanical softness (≈54 MPa) is presented. To enhance mechanical robustness without compromising electrical conductivity, a capillary‐force‐induced densification process, followed by a novel air‐pressure‐assisted flexibilization technique, is used. By infiltrating an elastomer matrix into the CNT pillars, polymer‐incorporated, vertically aligned CNT microelectrode arrays optimized for implantation are developed. The resulting devices exhibit enhanced mechanical compliance and stable insertion behavior, as confirmed by mechanical characterization and insertion tests into agarose gels and mouse brains. Histological analysis reveals reduced inflammatory responses compared to conventional tungsten microwires. Furthermore, in vivo electrophysiological recordings demonstrate reliable acquisition of visually evoked neural signals. These results highlight the potential of CNT‐based soft microelectrode arrays to overcome the mechanical and electrical limitations of existing neural interfaces, enabling more stable, biocompatible, and high‐fidelity neural recordings.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"246 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144500836","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}

Biopolymers are generally biodegradable, renewable, nontoxic, and easily available in nature and can be effective potential alternatives to synthetic plastics. However, the inherent limitations of biopolymers in terms of poor mechanical and barrier properties, as well as inadequate thermal stability, have hindered their widespread adoption in the food packaging industry. With the advent of nanoscience, new avenues for innovation in novel food packaging materials with enhanced functional attributes have been realized. Upon dispersion in a biopolymer matrix, inorganic or organic nanofillers, which possess certain physical and chemical properties at the nanoscale, make these composites useful as packaging materials; tailored mechanical, barrier, thermal, and optical properties have been reported to meet specific requirements for food preservation and packaging. This review discusses the effects of the reinforcement of different types of nanofillers on the mechanical, barrier, antimicrobial and antioxidant properties of biopolymeric matrices used for food packaging applications. The importance of standardized regulations for the safe use of nanomaterials in food packaging has also been discussed in detail.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"46 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144500525","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}

Herein, machine learning potential (MLP) is employed to accelerate molecular dynamics (MD) simulations, and pH‐field coupled microkinetic modelling is perfromed to unravel the pH dependence of CO2RR at the reversible hydrogen electrode (RHE) scale. Encouragingly, the developed MLP reveals that SnO2 adopts a nanorod‐like morphology, accurately reproducing experimentally observed reconstruction phenomena. Additionally, SnS2 prefers to form a rougher surface. Leveraging the precisely determined reconstructed surface, the exciting pH‐dependent behavior of Sn‐based catalysts is highlighted: the increase of pH will cause a left‐shift in the CO2RR volcano and ultimately enhance the catalyst's activity. Most importantly, the excellent agreement between the theoretical simulations and our subsequent experimental measurements validates the accuracy of the simulations in terms of turnover frequencies, providing a clear benchmarking analysis between experiments and the MLP‐MD‐assisted pH‐field coupled microkinetic modelling.

The precise functionalization of surfaces is pivotal in developing advanced thermal management solutions for next‐gen electronics cooling. Herein, it is demonstrated for the first time that picosecond‐laser functionalization of copper surfaces—comprising densely packed, self‐organized, quasi‐periodic microstructures—results in surfaces that are highly suited for such applications. The methodology uses large laser beams (typical radius of 150µm or higher) to facilitate the self‐organization of laser‐formed surface features that are orders of magnitude smaller. The resulting laser‐functionalized surfaces not only exhibit excellent fluid transport capabilities, but also demonstrate exceptional heat transfer performance. Integrated into wickless vapor chambers (VCs), these surfaces enable device thermal resistances as low as 0.12 K W−1 at 0.3 MW m−2 load, and values ≈0.2 K W−1 across the range 0.3–1.5 MW m−2—corresponding to almost 80% reduction compared to the thermal resistance of conventional wick‐lined VCs, as attested by a benchmarking study. Additionally, these functionalized surfaces have reduced sensitivity to working‐fluid charge ratio, proving their operational robustness.

Herein, an innovative approach for multifunctional manipulations of double‐emulsion droplet carriers including transportation, rotation, and core release is introduced. Functional samples can be effortlessly encapsulated within the inner cores of droplet carriers, while the carrier shell is composed of a commonly used yet biologically harmless mixture of polydimethylsiloxane(PDMS) and silicone oil. In the designed microdevice, droplet carriers are initially transported from the channel entrances to the target region through the traveling‐wave dielectrophoresis effect, followed by the rotation under a rotating electric field for measuring the electric property of the droplet carrier. Ultimately, the shell‐thinning and final break is triggered by sufficient electric Maxwell stress at droplet interfaces, leading to the release of nanoparticles and anti‐cancer drugs. The modulation of droplet carriers can be flexibly adjusted by changing the voltage, frequency, and phase variation direction of electric signals. Therefore, this droplet manipulation method can be promising for many applications needing sample loading, delivery, and release.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"22 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488791","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}

Based on evaporation thermodynamics theory, the review clarifies the intrinsic relationship between free water/bound water states and evaporation rates. Strategies to enhance water retention include: 1) physical barrier encapsulation, such as hydrophobic polymer membranes or shell structures; 2) network structure optimization, like interpenetrating or dual-network designs to improve water-holding capacity and regulate pore distribution; 3) molecular-level control, incorporating hydrophilic components (e.g., glycerol, ionic liquids) via hydrogen bonding to manipulate water states. Notably, eutectogels using low-volatility deep eutectic solvents outperform traditional water-based systems, achieving excellent mechanical performance and long-term moisturization. The review also discusses potential applications and identifies knowledge gaps, offering future research directions.

Herein, a small molecule of hydroxyethyl methacrylate (HEMA) is introduced to substitute the DMSO. The hydroxyl (─OH) and carbonyl (─C═O) groups in HEMA are simultaneously associated with formamidinium (FA+) and Pb2+ via hydrogen bonds and coordination bonds, respectively, which facilitates the formation of strongly bonded FAI‐HEMA‐PbI2 complexes in the precursor solution to regulate perovskite crystallization with improved crystallinity and preferred orientation. Moreover, the solidification of residual HEMA via in situ polymerization can stabilize crystal structure with suppressed defects and released lattice strain. Consequently, PSCs based on HEMA‐treated perovskite films achieve a decent power conversion efficiency (PCE) of 25.31% with superior stability, retaining 90% of their initial PCE after 1000 h storage. Importantly, the incorporated hydrophilic HEMA can largely promote the moisture resistance of the precursor solution by preventing water molecules from direct contact with perovskite components. More than 90% of the initial efficiency is maintained by using old precursor solutions aged in ambient air for 20 days, indicating an extended process window for device fabrication.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"634 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479101","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}
