Quantum-sized transition metal dichalcogenides possess unique advantages of charge delocalization and enrich uncoordinated electrons and short-range transfer kinetics, which are crucial to achieve rapid low-temperature charge transfer and high-temperature interface stability. Herein, a quantum-scale FeS2 loaded on three-dimensional Ti3C2 MXene skeletons (FeS2 QD/MXene) fabricated as SIBs anode, demonstrating impressive performance under wide-temperature conditions (- 35 to 65 °C). The theoretical calculations combined with experimental characterization interprets that the unsaturated coordination edges of FeS2 QD can induce delocalized electronic regions, which reduces electrostatic potential and significantly facilitates efficient Na+ diffusion across a broad temperature range. Moreover, the Ti3C2 skeleton reinforces structural integrity via Fe-O-Ti bonding, while enabling excellent dispersion of FeS2 QD. As expected, FeS2 QD/MXene anode harvests capacities of 255.2 and 424.9 mAh g-1 at 0.1 A g-1 under - 35 and 65 °C, and the energy density of FeS2 QD/MXene//NVP full cell can reach to 162.4 Wh kg-1 at - 35 °C, highlighting its practical potential for wide-temperatures conditions. This work extends the uncoordinated regions induced by quantum-size effects for exceptional Na+ ion storage and diffusion performance at wide-temperatures environment.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"7 1","pages":"15"},"PeriodicalIF":26.6,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144720054","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, the presence of larger FA+ cation induces to an expansion of the Pb-I octahedral framework, which unfortunately affects both the stability and charge carrier mobility of the corresponding devices. To address this challenge, we develop a novel low-dimensional (HtrzT)PbI3 perovskite featuring a conjugated organic cation (1H-1,2,4-Triazole-3-thiol, HtrzT+) which matches well with the α-FAPbI3 lattices in two-dimensional plane. Benefiting from the matched lattice between (HtrzT)PbI3 and α-FAPbI3, the anchored lattice enhances the Pb-I bond strength and effectively mitigates the inherent tensile strain of the α-FAPbI3 crystal lattice. The X-ray detector based on (HtrzT)PbI3(1.0)/FAPbI3 device achieves a remarkable sensitivity up to 1.83 × 105 μC Gyair-1 cm-2, along with a low detection limit of 27.6 nGyair s-1, attributed to the release of residual stress, and the enhancement in carrier mobility-lifetime product.

By accurately controlling the introduced included angle between the flexible template and the substrate, tilted nanostructures with a controllable angle are imprinted onto the substrate, although they are vertical on the template. By flexibly adjusting the electric field intensity and the included angle, large-area uniform-tilted, gradient-tilted, and high-angle-tilted nanostructures are fabricated. In contrast to traditional replication, the morphology of the nanoimprinting structure is extended to customized control.

However, for their sufficient skin penetration, conventional MNs employ long needles (≥ 600 μm), leading to pain and skin irritation. Moreover, it is critical to stably apply MNs against complex skin surfaces for uniform nanoscale drug delivery. Herein, a dually amplified transdermal patch (MN@EV/SC) is developed as the stem cell-derived EV delivery platform by hierarchically integrating an octopus-inspired suction cup (SC) with short MNs (≤ 300 μm). While leveraging the suction effect to induce nanoscale deformation of the stratum corneum, MN@EV/SC minimizes skin damage and enhances the adhesion of MNs, allowing EV to penetrate deeper into the dermis. When MNs of various lengths are applied to mouse skin, the short MNs can elicit comparable corticosterone release to chemical adhesives, whereas long MNs induce a prompt stress response. MN@EV/SC can achieve a remarkable penetration depth (290 µm) for EV, compared to that of MN alone (111 µm). Consequently, MN@EV/SC facilitates the revitalization of fibroblasts and enhances collagen synthesis in middle-aged mice. Overall, MN@EV/SC exhibits the potential for skin regeneration by modulating the dermal microenvironment and ensuring patient comfort.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"37 1","pages":"11"},"PeriodicalIF":26.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684410","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, these efficiencies are highly dependent on the thickness of the photoactive layer, which is typically around 100 nm. This sensitivity poses a challenge for industrial-scale fabrication. Achieving high PCEs in thick-film OPVs is therefore essential. This review systematically examines recent advancements in thick-film OPVs, focusing on the fundamental mechanisms that lead to efficiency loss and strategies to enhance performance. We provide a comprehensive analysis spanning the complete photovoltaic process chain: from initial exciton generation and diffusion dynamics, through dissociation mechanisms, to subsequent charge-carrier transport, balance optimization, and final collection efficiency. Particular emphasis is placed on cutting-edge solutions in molecular engineering and device architecture optimization. By synthesizing these interdisciplinary approaches and investigating the potential contributions in stability, cost, and machine learning aspects, this work establishes comprehensive guidelines for designing high-performance OPVs devices with minimal thickness dependence, ultimately aiming to bridge the gap between laboratory achievements and industrial manufacturing requirements.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"16 1","pages":"10"},"PeriodicalIF":26.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684411","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 pursuit of long durability introduces new challenges for battery energy density. The advent of electrode material offers effective support in enhancing the battery's long-duration performance. Often underestimated as part of the cathode composition, the binder plays a pivotal role in the longevity and electrochemical performance of the electrode. Maintaining the mechanical integrity of the electrode through judicious binder design is a fundamental requirement for achieving consistent long-life cycles and high energy density. This paper primarily concentrates on the commonly employed cathode systems in lithium-ion batteries, elucidates the significance of binders for both, discusses the application status, strengths, and weaknesses of novel binders, and ultimately puts forth corresponding optimization strategies.

In this work, we propose an autogenously transformed CoWO4/WO2 heterojunction catalyst, integrating a strong polysulfide-adsorbing intercalation catalyst with a metallic-phase promoter for enhanced activity. CoWO4 effectively captures polysulfides, while the CoWO4/WO2 interface facilitates their S-S bond activation on heterogenous catalytic sites. Benefiting from its directional intercalation channels, CoWO4 not only serves as a dynamic Li-ion reservoir but also provides continuous and direct pathways for rapid Li-ion transport. Such synergistic interactions across the heterojunction interfaces enhance the catalytic activity of the composite. As a result, the CoWO4/WO2 heterostructure demonstrates significantly enhanced catalytic performance, delivering a high capacity of 1262 mAh g-1 at 0.1 C. Furthermore, its rate capability and high sulfur loading performance are markedly improved, surpassing the limitations of its single-component counterparts.
