Here, we investigate a-IGZO transistors with both dimensions reduced to 50 nm and show that threshold-voltage scaling is governed by the coupling between edge stoichiometry and percolation-limited transport. Ar- and Cl2-patterned devices exhibit distinct width-dependent threshold-voltage shifts, while length scaling produces an opposite trend. Energy-dispersive spectroscopy, technology computer-aided design simulations, and random telegraph noise measurements reveal that percolative transport amplifies or compensates the impact of edge stoichiometry depending on etch chemistry. These results provide a geometry-process-percolation framework for threshold-voltage engineering in nanoscale oxide electronics.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148878663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key distinguishing feature of MXenes lies in the richness and tunability of their surface functional groups (Tx, e.g., -O, -OH, -F), which serve as a powerful lever for precisely engineering the material's structural, electronic, mechanical, and chemical characteristics. The deliberate modulation of Tx, achieved through Tx engineering, including in situ synthesis control or post-synthetic treatments, directly governs critical properties such as work function, electrical conductivity, hydrophilicity, and oxidation stability. These tailored properties, in turn, drive performance enhancements in surface-sensitive applications: in electrocatalysis, Tx engineering optimizes intermediate adsorption and charge transfer for reactions like hydrogen evolution and CO2 reduction; in energy storage devices such as batteries and supercapacitors, it enhances ion accessibility, redox activity, and cycling stability. This review systematically summarizes recent advances in surface Tx engineering of MXenes, elucidating the fundamental mechanisms linking Tx customization to property evolution and application-specific performance. By discussing Tx engineering strategies, structure-property-performance relationships, and mechanistic roles of distinct Tx, we aim to provide a deep understanding of how Tx tunability makes MXenes particularly suited for catalysis and energy technologies, while also outlining future directions for rational surface design in this rapidly evolving field.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2071-2107"},"PeriodicalIF":6.4,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148256338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the last few years, substantial growth has been observed in the engineering of these materials for the bulk photovoltaic effect (BPVE). BPVE is the conversion of electricity from light via an entirely distinct mechanism from the p-n junction photovoltaic device. The tunable crystal structures of 2D vdW materials, their ability to maintain clean interfaces, and the ease of forming heterostructures and heterojunctions facilitate the manipulation of crystal symmetry, electronic polarization, light-matter interactions, thereby providing an efficient platform for engineering the BPVE. Herein, we present a critical discussion of the fundamentals of engineering the BPVE using different material systems and innovative strategies based on previous scientific reports. The key challenges that can hinder device efficiency are also covered. The potential for a next-generation, self-powered, energy-efficient, flexible, and lightweight device utilizing the BPVE of 2D vdW materials is highlighted in this article.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2027-2052"},"PeriodicalIF":6.4,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148040232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their broad application is still restricted by lipid nanoparticle (LNP)-induced oxidative stress, rapid clearance of LNPs from the lung, and limited mRNA expression. Here, we show that incorporating a natural compound, acacetin, into the LNP formulation can overcome these delivery barriers and greatly improve inhaled vaccine effectiveness. A natural compound library containing 242 compounds was used in an in vitro screening experiment, and acacetin was identified as the lead compound that substantially increased LNP-mediated mRNA expression in A549 cells. We then incorporated acacetin in LNPs as a fifth component. After optimizing the formulation of LNPs in in vitro transfection assays and in vivo pulmonary delivery assays, we find acacetin-incorporated LNPs increased lung transfection by 10.82-fold. A mechanistic study showed that acacetin reshaped the intracellular environment of lung cells by activating antioxidant stress pathways and suppressing pro-inflammatory signaling, thereby maintaining high levels of mRNA translation. Inhaled administration of acacetin-incorporated LNPs, delivering mRNA encoding the SARS-CoV-2 spike protein, induced higher antigen-specific IgG (14.95-fold) and IgA (2.38-fold) levels than a conventional LNP formulation, without inducing toxicity. We demonstrate that acacetin-incorporated LNPs offer a simple and scalable strategy to improve the efficacy of inhaled mRNA vaccines.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2204-2214"},"PeriodicalIF":6.4,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148256354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The AgNWs were characterized by UV-vis spectroscopy, zeta potential analysis, dynamic light scattering, FESEM, TEM, and EDS to confirm their optical response, morphology, and elemental composition. The nanowires showed a plasmonic absorption band at 385 nm, a near-neutral zeta potential, and a mean diameter of 71.58 ± 22.78 nm, although minor secondary morphologies were observed. In the EAC mouse model, AgNWs reduced viable EAC cell counts in a non-linear dose-dependent manner, with the lower dose showing stronger inhibition than the higher dose. These findings suggest that AgNWs possess measurable anticancer activity, while also indicating that dispersion state and dose-dependent behavior require further mechanistic study before translational use can be considered.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2167-2177"},"PeriodicalIF":6.4,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148256346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
