Different from the typically used unimodal porous Cu, the bimodal structure provides big pores (hundreds of nanometers) for enough Zn deposition (high capacity) and small pores (10 nm) with a high specific surface area for high rates. Moreover, the formation of the Cu2O surface with Bi doping significantly reduces the Zn deposition overpotential. The np-Cu/Cu2O (Bi)-based half cells and symmetric cells exhibit much lower Zn deposition overpotential (88.7 mV) and excellent cycling stability (over 260 h), respectively, even at a large current density of 50 mA cm-2, obviously outperforming the pure Zn-based cells and most reported results. The dendrite issue and side reaction are also largely limited by the bimodal nanoporous structure design and surface modification. This work provides inspiration for developing an advanced Zn anode through porosity design and surface chemistry modulation.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"215 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144737439","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}

To address these challenges, we propose a ferroelectric-enhanced doping effect to conduct band engineering and charge redistribution, which effectively mitigates the Fermi level pinning effect and enables selective ambipolar behaviors, resulting in ideal electrical contact and efficient carrier transport. Furthermore, the polarization-induced floating gate introduces additional gain mechanisms through defect engineering and a tunneling effect, which significantly improves photomultiplication and carrier acceleration. Consequently, the as-fabricated phototransistor based on a WS<sub>2</sub>/graphene heterojunction and Al:HfO<sub>2</sub> ferroelectric layer exhibits outstanding performances, including a high detectivity of 2.38 × 10<sup>13</sup> Jones and an impressive photogain of 3.28 × 10<sup>7</sup>, without requiring an external gate bias.

Inspired by the excellent adhesion behavior of mussels, we developed a nanocarrier (Ac-NP) of catechol-decorated hyperbranched polyglycerol (HPG) to enable strong anchoring to ECM components (collagen I, laminin, proteoglycans), markedly improving the delivery efficacy of various anticancer agents. Meanwhile, to minimize its nonspecific ECM anchoring following intravenous injection, the nanocarrier was masked by 4-carboxyphenylboronic acid (PBA), and the resultant TAc-NPs exhibited specific tumor extracellular ECM-anchoring capability. TAc-NPs showed a 2.3-fold increase in tumor accumulation, with over 70% retained in the ECM. This ECM-anchored system significantly enhanced the therapeutic efficacy of extracellular (BB94), intracellular (doxorubicin), and membrane-targeted (BMS-1) drugs for efficient chemoimmunotherapy.

Precisely imaging nanoscale spatial disorder requires an order of magnitude increase in resolution capabilities. Here, we present a spatially resolved study of the exciton spectra of monolayer MoSe<sub>2</sub> in the visible range using cryogenic scattering-type scanning near-field optical microscopy (s-SNOM) operating down to 11 K. Mapping the exciton resonance across an hBN-encapsulated MoSe<sub>2</sub> monolayer, we achieve sub-50 nm spatial resolution and an energy resolution below 1 meV. We further investigate the material's near-field spectra and dielectric function, demonstrating the ability of cryogenic visible s-SNOM to reveal nanoscale disorder. Comparison to room-temperature measurements illustrates enhanced capabilities of the cryogenic s-SNOM to reveal fine-scale material heterogeneity. These results establish cryogenic visible s-SNOM as an effective nanoscale excitonic probe, offering valuable insights into 2D material heterogeneity and nanoscale sensing.</p>","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":""},"PeriodicalIF":9.1,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740603","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}
