However, the advancement of these materials is impeded by significant challenges, particularly the poor quality of films resulting from the facile oxidation of Sn2+ to Sn4+ and the inherent difficulties in controlling crystallization kinetics. To mitigate these issues, the design of low-dimensional (LD) Sn-Pb perovskites has gained considerable attention, as 2D structures are associated with improved stability and distinctive optoelectronic properties. This review systematically investigates the optoelectronic characteristics of 2D Sn-Pb perovskites arising from dimensional reduction while elucidating the intricate relationship between their microstructure and optoelectronic behavior. Additionally, the substantial progress made in applying 2D Sn-Pb perovskites within single-junction and heterojunction perovskite solar cells (PSCs) is highlighted. Emerging applications in fields such as near-infrared (NIR) detection, circularly polarized light detection, and memristors are also discussed. Given the current understanding, further exploration of diverse ligands and Sn-Pb compositions in 2D systems is crucial for realizing their full potential in practical applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"33 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872589","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}

However, conventional electrode designs rely on expensive nickel‐based materials and complex fabrication processes, limiting their scalability. This study presents a cost‐effective and scalable approach that transforms ultralow‐cost steel wool into freestanding electrodes for industrial‐scale AEMWE. The fibrous structure, anchoring an activated nickel–iron layered double hydroxide catalyst, enables a highly active bifunctional electrode, achieving 1 A cm⁻2 at 1.815 V with an ultralow degradation rate of ≈0.041 mV h⁻¹ over 1800 h. Unlike conventional electrodes, the interwoven fibrous matrix eliminates the need for porous transport layers and forms an interlocking interface with the membrane, significantly enhancing performance and durability. Under industrial conditions, a prototype AEMWE single stack (≈16 cm2) delivers over 16 A at 1.8 V and nearly 30 A at 2.0 V, maintaining stable operation over 400 h under dynamic conditions. This iron‐rich system, based on a scalable one‐pot corrosion process, enables the upcycling of mass‐produced steel wool into 2 m scale electrodes at a cost of 4.59 USD m⁻2, over 200 times cheaper than conventional nickel‐based electrodes. These findings establish a new paradigm for cost‐efficient and durable electrode design in industrial AEMWE applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"24 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866663","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}

The green leather containing rich interspaces among dense collagen fibers is a promising skeleton to load soft ionic gels for constructing ionic skins. However, such ionic skin is still plagued by a weak interior combination of the two components and inhomogeneous conductivity. Herein, a multiscale interfacial designed ionogel/leather ionic skin with uniform ionic conductivity is prepared by incorporating ionic liquid (IL) into the polyvinyl alcohol (PVA)-polyacrylamide (PAM)/Leather composite to construct strong interior bonding and continuous ionically conductive paths. The ionic liquid induces volume shrinkage accompanied by dense entanglements of PVA-PAM polymer chains and collagen fibers, together with polymer-rich domains associated by hydrogen bonds among various functional groups, contributing to a strong and tight combination of soft PVA-PAM/IL ionogel matrix and tough leather skeleton. The bonding force between the two components is increased by 2.5 times. Such integration confers the resultant ionic skin with applications in wearable strain, temperature, and respiration sensing. This study enhances the overall performance of the ionogel/leather ionic skin and expands its applications for continuous monitoring of multiple physiological signals.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"8 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867115","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}

The experimental and simulation results show that increasing the flux length and ordered orientation is very important to improve the absorption performance of 1D magnetic absorber. The CFC-LC-E (long-chain CFC aligned along the electric field direction) prepared based on the above characteristics successfully achieves a high-performance microwave absorption effect, with a minimum reflection loss value (RLmin) of −66.4 dB. Notably, it maintains stable performance against oblique incidence (within 90°) and polarizations (transverse electric and transverse magnetic).

Compared to systems that emit distinct colors by combining multiple molecules, single-molecule white-light emission systems offer notable advantages, such as simple preparation, good repeatability and stability. In this study, a novel fluorescent molecule (BTP-CHO) was developed. For the first time, a single-molecule near-white light emission system by exploiting the internal equilibrium of aldehyde-gemdiol in water of BTP-CHO was constructed. BTP-CHO exists predominantly as the aldehyde form in DMSO and shows green fluorescence; while BTP-CHO shows blue fluorescence because of the internal equilibrium of aldehyde-gemdiol in water. Polychromatic photoluminescence could be achieved by fine-tuning various parameters, including excitation wavelength and solvent ratio. Additionally, we synthesized three derivatives of BTP-CHO for further investigating the universality of this strategy and the results indicate that the strategy has good universality. Finally, BTP-CHO was successfully applied in the development of information encryption and near-white light hydrogels. This work provides new insights into the design of organic single-molecule white-light emitters and broadens the scope of research on aldehyde-gemdiol intrinsic equilibrium about white-light emitting.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"25 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867177","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}

One promising approach involves receptor-mediated transcytosis via Angiopep-2 peptide (Ang-2)-conjugated nanoparticles. However, the influence of Ang-2 density on BBB penetration remains poorly understood. We developed a versatile polymeric nanoparticle system with tunable Ang-2 surface density and systematically examined its influence on BBB penetration through various in vitro assays and an in vivo study. The results reveal a nuanced relationship between ligand density and BBB penetration across experimental setups. In 2D cell culture, Ang-2 density positively correlates with nanoparticle association in human cerebral microvascular endothelial cells (hCMEC/D3) with a distinctive inflection point. Conversely, in the Transwell model, higher Ang-2 density negatively correlate with BBB penetration, while the BBB-glioblastoma (GBM)-on-a-chip shows the opposite trend. Disparities may be due to differences in avidity under static versus dynamic conditions, modulating nanoparticle interactions due to fluidic forces. In vivo studies align with the microfluidic model. Loading doxorubicin into the optimized nanoparticles achieves controlled pH-responsive release and enhanced anticancer effects against U87 GBM cells in 2D cell cultures and a 3D BBB-GBM-on-a-chip. These results underscore the importance of optimizing Ang-2 density for BBB penetration and emphasize the utility of dynamic models for the preclinical assessment of brain-targeting nanoparticles.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"24 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872842","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}

Combining with experimental and theoretical methods, the well‐designed FePC with plane‐symmetric Fe─P4─C configuration exhibits strengthened catalytic effect toward reversible conversion between LiPS and Li2S, that endows S@FePC cathodes with superior electrochemical performance. The prepared S@FePC coin cells achieve prolonged cyclic stability of over 1000 cycles at 1C with a high capacity retention of 77.8%. Even at high sulfur loading (5.7 mg cm−2) and low E/S ratio (6.2 µL mgS−1), the areal capacity reached 6.0 mAh cm−2 and 88.3% of it is retained after 100 cycles at 0.1 C. Moreover, the prepared 0.6 Ah S@FePC pouch cell exhibits higher capacity retention of 76.3% after 100 cycles at 0.1 C compared with S@FeNC. Meanwhile, the prepared 8Ah S@FePC pouch cell approaches a high specific energy of 401 Wh kg−1 at 0.1 C proving its practicability.
