Herein, it proposes a heterojunction with asymmetric W-Cl anion layer in Bi2WO6 (abbreviated as BWOC). The asymmetric W-Cl anion layer results in unbalanced electron density distribution and thus enables to establish atomic-level donor–acceptor structure as well as larger electrostatic potential in the heterojunction, which facilitate the charge carrier separation and transfer kinetics. Simulation on the intermediates of the CO2 photoreduction process demonstrates that Bi2WO6 with asymmetric W-Cl anion layer possesses smaller energy barrier for the rate-determining step of *COOH endothermic formation, and it is thermodynamically more favorable to generate CO as further confirmed by the detection of intermediates over in situ Fourier transform infrared spectroscopy. As a result, BWOC achieved rather high CO yield with the value of 32.11 µmol g−¹ h−¹ which is nearly four times higher than that of pure Bi2WO6. The construction of asymmetric anion layer in this work provides new insights for the design of efficient photocatalytic systems toward CO2 reduction.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"73 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736858","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}

In this paper, a KCoNiF3/NiCo-LDH supported on activated carbon cloth (KCNF-LDH/ACC) heterojunction structural composite material is in situ synthesized on carbon cloth by doping K+ into nickel-cobalt double hydroxide, and the loading amount can reach 12 mg cm−2. The doping of K⁺ can enhance the stability and rate performance of NiCo-LDH. The electrode with the optimal K+ doping amount (KCNF-LDH-3/ACC) exhibits a capacitance of 10.1 F cm−2 / 841 F g−1 at 1 mA cm−2. When the current increases to 50 mA cm−2, capacitance can still maintain 85% of the initial capacity. The capacity retention rate reaches 91% after 20 000 cycles. An asymmetric supercapacitor is assembled with KCNFo-LDHo-3/ACC as the positive electrode and AC as the negative electrode. It outperformed the previously published NiCo-LDH supercapacitors with an energy density of 1.14 mWh cm−2 at a power density of 4 mW cm−2.

Conventional antibiotics can increase the risk of drug resistance and non-specifically harm microflora, disrupting their balance. In addition to pathogenic bacteria, lung inflammation also damages tissue. This study develops an aptamer/polymer-functionalized mesoporous polydopamine/silver nanocomposite (Apt/ODEA-PDA/Ag-ICG) to specifically target A. baumannii and sequentially exhibit antibacterial/antioxidative properties for pneumonia treatment. After synthesizing the polyzwitterion (ODEA), the polymer/aptamer is conjugated with the PDA/Ag core, and ICG is further labeled to fabricate the nanocomposite. Upon intratracheal instillation, nanocomposites penetrate the mucus barrier with the help of polyzwitterions. The nanocomposite precisely targets A. baumannii through specific recognition by the aptamer, without affecting other microflora. Moreover, ICG is conjugated and distributed disorderedly within the polymer. ICG near the PDA/Ag core contributes to high NIR-I absorbance and good photothermal ability. ICG further from the PDA/Ag acts as a fluorescent molecule for specific A. baumannii imaging. Furthermore, PDA/Ag efficiently exhibits synergistic antibacterial activity owing to the acidic environment/heat-accelerated Ag+ release and photothermal effect. Importantly, alongside Ag+ release, the antioxidant ability of PDA scavenges reactive oxygen species and alleviates inflammation, thereby accelerating pneumonia treatment. In summary, nanocomposites provide an alternative approach for designing advanced antibacterial systems.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"90 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736855","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}

Strongly resonant structures are commonly used to achieve lower laser operating power and higher efficiency. However, this approach typically compromises other critical performance metrics, such as protection power range, maximum operating power, bandwidth, and angular range. Here, a novel strategy is proposed using weakly resonant structures to realize nonreciprocity while preserving high performance across these metrics. This achievement stems from the large out-of-plane refractive index asymmetry in the Si/VO2 catenary structure, enabling robust nonreciprocal transmission with high efficiency across a broad bandwidth (8–11.5 µm) and angular range (>75°) theoretically. This design also shows a higher operating power ceiling and extends the existing tunable nonreciprocal range by an order of magnitude. Experiments validate the tunable nonreciprocal range at 10.6 µm wavelength. Protection capabilities are significantly enhanced through wavefront modulation, offering rapid and effective protection from below the phase transition to above the damage threshold. This work presents a novel paradigm for robust nonreciprocal metasurfaces, with considerable potential for applications in remote sensing, environmental monitoring, biomedicine, and industrial manufacturing.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"34 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736910","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}

NETs consist of intricate biomacromolecules and exhibit web-like microstructure, endowing them with multifaceted roles in both physiological and pathological processes. In this review, research progress is systematically examined on NETs from a materials science perspective. First, the origin and transformation of NETs are introduced, and their functional mechanisms of various NET components are thoroughly dissected rather than conventionally treating NETs as a single entity. Second, given their complex components and functions, NETs are revealed as a potential biomarker for disease prediction. Third, typical characterization technologies for the analysis of NETs are summarized. Fourth, artificial materials inspired by NETs are discussed. In addition, the natural regulatory processes of NETs provide bio-inspired prototypes for the design of advanced functional materials.

To overcome this challenge, supramolecular self-assembly strategies are employed to fabricate multifunctional aggregates. Herein, a versatile supramolecular inclusion—AdA8@β-CD is constructed by loading an amantadine-modified bactericidal structure (AdA8) into β-cyclodextrin (β-CD) via host–guest recognition driving force, which spontaneously self-assembles into biocompatible hollow nanocapsules. This smart optimization not only allows the bactericides to quickly stay on the hydrophobic leaves, preventing their droplets from splashing and bouncing but also improves the performance of removing biofilm barriers. At a lower concentration of 5 µg mL−1, the disruption rate of AdA8@β-CD to Xanthomonas biofilm reaches 78.3%. Moreover, AdA8@β-CD enhances the limitation of bacterial motility and extracellular enzyme secretion, thereby reducing bacterial colonization and pathogenicity. These reformative properties are undoubtedly transmitted to in vivo activity, providing corresponding preventive efficacies of 51.1% and 73.2% against rice bacterial blight and citrus canker at 200 µg mL−1, which are notably better than those of traditional agrochemicals—thiodiazole-copper-20%SC (33.9%/37.4%), kasugamycin (28.7%), and AdA8 itself (43.8%/45.3%).

However, the rational design of 3D-nanochannel membranes that simultaneously achieve high permeance and selectivity remains a challenge, arising from the scarcity of appropriate molecular building blocks and the reliance on empirical synthetic methods. Herein, an innovative 3D polyacylhydrazone (PAH) membrane with unique pore-interconnected structures is constructed on a porous hydrogel using contorted tetrahedral aldehydes (TFS) monomers via an in situ interface-confined strategy. Manipulation of side alkyl chain lengths within terephthalohydrazide (TPH) derivates enabled the enhancement of microporosity and tunable pore environment of PAH nanofilms. Molecular dynamics simulations revealed that TPHEO linkers with higher reactivity and moderate steric hindrance facilitate superior pore interconnectivity and sharpened pore size distributions. The resulting PAH membranes achieved exceptional methanol permeances of 10.1 L m−2 h−1 bar−1 and small molecular weight cut-offs of 310 Da, outperforming the state-of-the-art polyamide membranes. This further translated into an outstanding capability in the fractionation of active pharmaceutical ingredients within organic solvent systems.
