Developing efficient and stable non-precious metal electrocatalysts capable of accelerating the alkaline hydrogen evolution reaction (HER) is crucial for sustainable hydrogen production. Herein, self-supported NiMoO4@NiX/MoX (X = S, Se, Te) heterostructured nanoarrays were fabricated on nickel foam (NF) via a two-step hydrothermal method. Systematic investigations reveal that the introduction of chalcogenides effectively modulates the electronic structure and the oxygen vacancy (Ov) concentration of the catalysts. Notably, the NiMoO4@NiTe2/MoTe2 heterostructure delivered the highest Ov concentration and Mo4+ active site density, driven by the low electronegativity and large atomic radius of tellurium (Te) atoms. Density functional theory (DFT) calculations reveal that chalcogen regulation shifts the d-band center, thereby optimizing hydrogen adsorption, with Te exhibiting the most favorable adsorption behavior for enhanced HER activity. Consequently, the NiMoO4@NiTe2/MoTe2 catalyst required an overpotential of only 46 mV to achieve a current density of 10 mA cm−2 with a Tafel slope of 58.03 mV dec−1, while maintaining stable operation for 70 h. The structure–activity relationships of chalcogenide heterostructures for alkaline hydrogen evolution are revealed in this work.

开发高效稳定的非贵金属电催化剂加速碱性析氢反应是实现可持续制氢的关键。本文采用两步水热法在泡沫镍（NF）上制备了自支撑NiMoO4@NiX/MoX （X = S, Se, Te）异质结构纳米阵列。系统研究表明，硫族化合物的引入有效地调节了催化剂的电子结构和氧空位（Ov）浓度。值得注意的是，NiMoO4@NiTe2/MoTe2异质结构具有最高的Ov浓度和Mo4+活性位点密度，这是由碲（Te）原子的低电负性和大原子半径所驱动的。密度泛函理论（DFT）计算表明，硫的调节改变了d带中心，从而优化了氢的吸附，其中Te表现出对增强HER活性最有利的吸附行为。因此，NiMoO4@NiTe2/MoTe2催化剂只需要46 mV的过电位就可以达到10 mA cm−2的电流密度，Tafel斜率为58.03 mV dec−1，并保持稳定运行70 h。本研究揭示了硫系异质结构对碱性氢演化的构效关系。

A novel method was carried out for investigating the growth of N-doped nanoporous graphitic structures from thermal pyrolysis. N-doped catalytic active centers were optimized by inheriting structure of 4-Methylimidazole.In three kinds of methylimidazoles, the weakest bond is between methyl and heterocyclic structure, according to calculation of bond energy by using density functional theory. Thus the methyl group was first broken in the pyrolysis, leading to they were prone to incomplete thermal pyrolysis, because the reaction time was only a few seconds in their floating catalytic pyrolysis; the rest of methylimidazoles formed clusters, and then their free radicals made clusters linked to graphitic structure, which led to 4-imidazole like (MIL) catalytic active centers formed. X-ray photoelectron spectroscopy analysis revealed that more than 50 % N-doped structure were imidazole-like structure among catalysts prepared from methylimidazoles. According to rotating ring-disk electrode tests and DFT calculations, the 4-MIL catalytic structure exhibited the highest catalytic activity among three catalysts prepared from methylimidazoles: the onset potential of 4MIL-GNCs was close to 20 % commercial Pt/C (0.94 V vs. 0.96 V (RHE)). The 4-MIL-GNCs had high electron transfer number (n=3.73) and high kinetic current density Jk = 7.12 mA cm-2 at 0.6 V; the rate determining step of 4-MIL-GNCs had the lowest energy barrier in oxygen reduction among catalysts prepared from methylimidazoles (0.67 vs. 0.79 and 1.16 eV).

提出了一种新的方法来研究氮掺杂纳米多孔石墨结构的热裂解生长。通过继承4-甲基咪唑的结构，优化了n掺杂催化活性中心。根据密度泛函理论计算的键能，在三种甲基咪唑中，甲基与杂环结构之间的键最弱。因此甲基在热解过程中首先断裂，导致它们容易发生不完全热热解，因为它们在浮式催化热解中反应时间只有几秒钟；其余的甲基咪唑形成簇状结构，其自由基形成簇状连接石墨结构，形成4-咪唑类（MIL）催化活性中心。x射线光电子能谱分析表明，在以甲基咪唑为原料制备的催化剂中，超过50%的n掺杂结构为类咪唑结构。根据旋转环盘电极测试和DFT计算，在三种甲基咪唑制备的催化剂中，4-MIL的催化结构表现出最高的催化活性：4-MIL - gncs的起始电位接近20%的商业Pt/C （0.94 V对0.96 V (RHE)）。在0.6 V时，4-MIL-GNCs具有较高的电子转移数（n=3.73）和较高的动态电流密度Jk = 7.12 mA cm-2；甲基咪唑催化剂中4-MIL-GNCs的氧还原能垒最低（0.67 eV比0.79 eV和1.16 eV）。

Extracellular vesicles (EVs) exhibit unique biological performance in intercellular communication and drug delivery, yet their clinical translation is hindered by limited scalability, compositional heterogeneity, and regulatory complexity. Here, we report the rational design at the nanoscale of fully synthetic liposomal EV mimetics (Lipo-EVs) engineered to replicate the key biomechanical properties of small EVs while retaining the manufacturability and compositional control of synthetic systems. By systematically tuning membrane lipid composition, with a particular focus on cholesterol content, we identify a formulation that closely reproduces the nanoscale membrane packing, structure–property relationships, and nanomechanical behavior of HEK293-derived EVs. Advanced mechano-fluorescence assays and atomic force microscopy reveal that Lipo-EVs interact with model membranes in a manner closely resembling native EVs, especially under cholesterol-rich conditions, highlighting key principles of nanoscale membrane organization and interface mechanics. The optimized Lipo-EVs further display high colloidal stability, robust nanoscale integrity, compatibility with lyophilization and recovery, and efficient, homogeneous cellular uptake without detectable cytotoxicity.

Efficient charge separation at the BiVO4/cocatalyst interface is crucial for high-performance photoelectrodes, as it directly determines the availability of surface charges for solar water oxidation. However, achieving robust molecular-level connections to ensure superior interfacial quality remains challenging. Herein, we report a two-step photo-assisted deposition method followed by calcination to introduce vanadyl ions (VO2+) to form an O–V–O covalent structure at the BiVO4/FeNiOx interface (denoted as BiVO4/VOFeNiOx), thereby enabling a strong interfacial interaction. For comparison, direct FeNiOx deposition yields 4.23 mA cm–2 at 1.23 V vs. RHE, whereas the optimized BiVO4/VOFeNiOx photoanode achieves 6.69 mA cm–2 under AM 1.5 G illumination, corresponding to a 3.9-fold enhancement over pristine BiVO4. Furthermore, this architecture exhibits a 3.5-fold improvement in hole migration rate and excellent operational stability exceeding 30 hours. Systematic studies reveal that the introduction of O–V–O interfacial bonds induces a redistribution of electron density and strong electronic coupling between BiVO4 and FeNiOx. This optimized interfacial configuration facilitates charge transport, culminating in a substantial 76% reduction in charge transfer resistance. This work highlights the potential of interfacial engineering in facilitating charge transport, providing insights into the rational design of efficient photoanodes for solar energy conversion.

BiVO4/助催化剂界面上的高效电荷分离对于高性能光电极至关重要，因为它直接决定了太阳能水氧化表面电荷的可用性。然而，实现强大的分子级连接以确保优越的界面质量仍然具有挑战性。在此，我们报道了一种两步光辅助沉积方法，然后煅烧引入钒离子（VO2+）在BiVO4/FeNiOx界面（记为BiVO4/VOFeNiOx）形成O-V-O共价结构，从而实现了强的界面相互作用。相比之下，直接沉积的FeNiOx在1.23 V下比RHE产生4.23 mA cm-2，而优化的BiVO4/ vfeniox光阳极在AM 1.5 G照明下达到6.69 mA cm-2，相当于比原始BiVO4增强3.9倍。此外，该结构的井眼迁移速度提高了3.5倍，并且在30小时以上具有出色的运行稳定性。系统研究表明，O-V-O界面键的引入导致了BiVO4和fenix之间电子密度的重新分布和强电子耦合。这种优化的界面结构有利于电荷传输，最终使电荷转移电阻降低了76%。这项工作强调了界面工程在促进电荷传输方面的潜力，为合理设计用于太阳能转换的高效光阳极提供了见解。

Carbon dioxide (CO2) emission remains one of the solicitude concerns for society to achieve net-zero emissions. The functionalized nanocrystals have recently exhibited their potential to capture CO2. We synthesized ZnO and Zn1-xAgxO nanocrystals by chemical co-precipitation to fulfil the aim of CO2 capture. The X-ray diffraction spectra of ZnO nanocrystals have depicted their hexagonal wurtzite structure; however, Ag doping shifts the (100), (002), and (101) reflection peaks toward higher 2θ values, indicating lattice distortion and a reduction in crystallite size. Besides, the X-ray photoelectron spectroscopy analysis shows that Zn1-xAgxO nanocrystals exhibit around 0.5 at.% content of Ag in the ZnO lattice. Henceforth, the nanocrystals have been functionalized with N-annulated perylene tetraester (PT) to enhance their reactivity. The ability of these nanocrystals to capture CO2 and its relevance for sustainable climate initiatives have been examined by CO2-temperature programmed desorption (CO2-TPD) studies. This study reveals that the CO2 molecules are effectively adsorbed on the PT-functionalized Zn1-xAgxO nanocrystals and do not detach until 400 °C, which has been explained using the Polanyi-Wigner relation. This investigation demonstrates a compelling aspect of maintaining an environmentally sustainable and pollution-free ecosystem.

二氧化碳（CO2）排放仍然是社会关注的问题之一，以实现净零排放。功能化纳米晶体最近展示了它们捕获二氧化碳的潜力。采用化学共沉淀法合成了ZnO和Zn1-xAgxO纳米晶，以达到捕获CO2的目的。氧化锌纳米晶体的x射线衍射光谱描述了其六方纤锌矿结构；然而，Ag掺杂使（100）、（002）和（101）反射峰向更高的2θ值移动，表明晶格畸变和晶体尺寸减小。此外，x射线光电子能谱分析表明，Zn1-xAgxO纳米晶体在0.5 at左右。氧化锌晶格中银的含量。此后，纳米晶体被n环苝四酯（PT）功能化以提高其反应活性。这些纳米晶体捕获二氧化碳的能力及其与可持续气候倡议的相关性已经通过二氧化碳温度程序解吸（CO2- tpd）研究进行了检验。该研究表明，CO2分子被有效吸附在pt功能化的Zn1-xAgxO纳米晶体上，直到400°C才分离，这已经用Polanyi-Wigner关系来解释。这项调查显示了维持环境可持续和无污染生态系统的一个引人注目的方面。

Oxidative stress is a fundamental pathological contributor to Alzheimer's disease and is closely linked to amyloid-beta-mediated toxicity, tau dysregulation, mitochondrial impairment, and progressive neuronal degeneration. Among the associated reactive oxygen species, hydrogen peroxide (H₂O₂) is a mechanistically relevant redox intermediate and an important oxidative stress biomarker. Herein, an Au@NH₂-MIL-101(Fe) hybrid was rationally engineered as an electrocatalytically active sensing interface for H₂O₂ determination. The hybrid was constructed by integrating conductive Au nanodomains with an amino-functionalized Fe-based metal-organic framework, thereby combining the high surface area, porous architecture, and accessible coordination environment of NH₂-MIL-101(Fe) with the superior conductivity and catalytic activity of Au. Electrochemical investigations revealed that Au@NH₂-MIL-101(Fe)/SPCE exhibited substantially enhanced interfacial electron-transfer kinetics and electrocatalytic reduction of H₂O₂ relative to bare SPCE, MIL-101(Fe), and NH₂-MIL-101(Fe). Under optimized conditions, the sensor delivered a linear range of 0.01 to 429.7 μM and a limit of detection of 0.063 µM. In addition, the platform showed good selectivity, operational stability, reproducibility, and satisfactory performance in H₂O₂-spiked serum and urine samples, highlighting its promise for oxidative stress-related electroanalysis relevant to Alzheimer's disease.

氧化应激是阿尔茨海默病的基本病理因素，与淀粉样蛋白介导的毒性、tau蛋白失调、线粒体损伤和进行性神经元变性密切相关。在相关的活性氧中，过氧化氢（H2O2）是一种机制相关的氧化还原中间体，也是一种重要的氧化应激生物标志物。本文合理地设计了Au@NH2-MIL-101（Fe）杂化物作为测定H2O2的电催化主动传感界面。该杂化物通过将导电的Au纳米结构域与氨基功能化的Fe基金属有机骨架相结合，将NH2-MIL-101（Fe）的高表面积、多孔结构和易于接近的配位环境与Au的优异导电性和催化活性相结合。电化学研究表明，相对于裸SPCE、MIL-101（Fe）和NH2-MIL-101(Fe), Au@NH2-MIL-101(Fe)/SPCE具有显著增强的界面电子转移动力学和电催化还原H2O2的能力。在优化条件下，传感器的线性范围为0.01 ~ 429.7 μM，检测限为0.063µM。此外，该平台在添加h2o2的血清和尿液样本中表现出良好的选择性、操作稳定性、重复性和令人满意的性能，突出了其在与阿尔茨海默病相关的氧化应激相关电分析方面的前景。

Under optimized conditions, the sensor delivered a linear range of 0.01 to 429.7 μM and a limit of detection of 0.063 µM. In addition, the platform showed good selectivity, operational stability, reproducibility, and satisfactory performance in H2O2-spiked serum and urine samples, highlighting its promise for oxidative stress-related electroanalysis relevant to Alzheimer's disease.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":" ","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clathrin-mediated endocytosis (CME) is one of the most important pathways for transporting nanoparticles (NPs) into cells. It has been demonstrated that a single large NP can effectively trigger CME when it exceeds a certain threshold, thereby carrying nearby small NPs into cells and significantly enhancing their cellular uptake. However, it is unclear what property of the NPs, mass or size, contributes more to the CME triggering. Herein, we demonstrate that size is more important than mass in CME triggering by using a special trio of accurately synthesized silica NPs. One of the trio (Ag@SNP80) with a silver core has the same size as the 80 nm silica NPs (SNP80) and the same mass as the 100 nm silica NPs (SNP100). SNP80 is smaller than the CME triggering threshold, whereas SNP100 exceeds it. By comparing the different enhancing effects of this particular trio on the cellular uptake of 40 nm silica NPs (FSNP40), we are able to compare their different capabilities in triggering CME. Results from both HeLa and A549 cells showed the same order of the enhancing effect, with SNP100 > Ag@SNP80 ≈ SNP80, clearly demonstrating that size is more important than mass in triggering CME. This conclusion is further confirmed by the enhanced cellular uptake of 70 nm polystyrene NPs (FPS70) by the trio of SNPs in the same order. This finding improves our understanding of how NPs and other materials are internalized by cells and sheds light on the fundamental mechanisms of CME.

网格蛋白介导的内吞作用（CME）是纳米颗粒进入细胞的重要途径之一。研究表明，当单个大NP超过一定阈值时，它可以有效地触发CME，从而将附近的小NP携带到细胞中，并显著增强其细胞摄取。然而，目前尚不清楚NPs的哪种特性，质量还是大小，对CME的触发作用更大。在这里，我们证明了尺寸比质量在CME触发中更重要，通过使用一个特殊的三个精确合成的二氧化硅NPs。其中一个（Ag@SNP80）具有银芯，其尺寸与80纳米二氧化硅纳米粒子（SNP80）相同，质量与100纳米二氧化硅纳米粒子（SNP100）相同。SNP80小于CME触发阈值，而SNP100超过该阈值。通过比较这三种化合物对40 nm二氧化硅NPs （FSNP40）细胞吸收的不同增强效应，我们能够比较它们在触发CME方面的不同能力。HeLa和A549细胞的结果显示出相同的增强效应顺序，SNP100 > Ag@SNP80≈SNP80，清楚地表明在触发CME时，大小比质量更重要。这一结论进一步被以相同顺序的三个snp增强的70 nm聚苯乙烯NPs （FPS70）的细胞摄取所证实。这一发现提高了我们对NPs和其他物质如何被细胞内化的理解，并揭示了CME的基本机制。

We present a low-cost, scalable technique for mapping local electrical properties across large areas with micrometer-scale lateral resolution. The method utilizes a flexible polymer cantilever coated by microfabricated graphite electrodes to probe local surface resistance. Samples can be scanned on a motorized translation stage, enabling automated, spatially resolved electrical measurements over centimeter-scale regions. The use of graphite electrodes ensures low friction and wear for both the sample and the electrodes, allowing repeated measurements on thin films without sample damage, unlike conventional metal probes. We demonstrate robust, pixel-by-pixel resistance maps on various samples, including patterned graphite thin films and ITO on glass structures. Its simplicity, adaptability, and user-friendly operation makes this platform well-suited for rapid electrical testing and high-throughput quality control in advanced electronics research.

Aqueous zinc-iodine (Zn-I2) batteries are considered promising candidates for large-scale energy storage, owing to the abundant resources of zinc anodes, high theoretical capacity, excellent safety, as well as the fast reaction kinetics and low cost of iodine (I2) cathodes. However, their application is still limited by coupled failure at the cathode and anode interfaces. On the cathode side, polyiodides easily cause shuttle effects, self-discharge, and active I2 loss, while the anode faces core issues such as dendrite formation, hydrogen evolution, corrosion and deposition of by-products. Meanwhile, the migration of polyiodides and OH -/pH disturbances induced by anode side reactions amplify each other, further accelerating battery degradation. Electrolyte additives, due to their structurally designable nature, low dosage, and good compatibility, can synergistically regulate both interfaces of the cathode and anode, making them an effective strategy to mitigate coupled failures. This review systematically summarized the research progress of additives with different molecular configurations in aqueous Zn-I2 batteries, focusing on their structural characteristics, dual-interface mechanisms, and performance. The review also discusses challenges in mechanistic evidence, evaluation standards, adaptability to complex working conditions, and molecular design, and envisions the development direction of additives for Zn-I2 batteries with high loading, long lifespan, and multi-electron reactions.

由于锌阳极资源丰富、理论容量高、安全性好、反应动力学快、成本低等优点，锌-碘（Zn-I2）水基电池被认为是大规模储能的理想选择。然而，它们的应用仍然受到阴极和阳极界面耦合失效的限制。在阴极侧，多碘化物容易造成穿梭效应、自放电和活性I2损耗，而阳极则面临枝晶形成、析氢、腐蚀和副产物沉积等核心问题。同时，多碘化物的迁移和阳极副反应引起的OH -/pH扰动相互放大，进一步加速了电池的退化。电解质添加剂由于其结构可设计性、低剂量和良好的相容性，可以协同调节阴极和阳极的界面，使其成为减轻耦合失效的有效策略。本文系统综述了锌离子电池中不同分子构型添加剂的研究进展，重点介绍了其结构特点、双界面机理和性能。综述了锌离子电池在机理证据、评价标准、复杂工况适应性、分子设计等方面面临的挑战，展望了高负载、长寿命、多电子反应的锌离子电池添加剂的发展方向。

Controlling and manipulating temperature at the nanoscale hold substantial promise for advancing applications such as photothermal therapy, nanoscale chemical reactions, and micro/nanodevices. However, current temperature regulation methods predominantly rely on continuously tunable optical parameters (e.g., wavelength and polarization), which limit discrete and digitally addressable control states and result in insufficient degrees of freedom for tailoring local temperature distributions. The orbital angular momentum (OAM) of light offers a novel perspective for light–near-field thermal interactions, yet its potential to regulate nanoscale spatial temperature distributions remains unexplored. Herein, we demonstrate the unique regulatory role of the OAM of vortex beams for nanoscale thermal fields. By tuning the phase distribution of vortex beams characterized by the helical phase factor eilϕ, pronounced spatially asymmetric temperature distributions and multiple local temperature inversions are induced in plasmonic structures. Through the synergistic modulation of key vortex beam parameters—including topological charge l, wavelength, and polarization direction—we achieve multi-degree-of-freedom reconstruction of thermal near-field distributions with subwavelength spatial resolution, where the temperature increase ratio is tunable over the range of 0.6–1.7. This work not only provides discrete and digitally addressable control states for thermal regulation but also broadens the understanding of light–thermal field interactions. It offers guidance for realizing multidimensional far-field optical control over local thermal distributions, opening a new route toward frontier applications such as micro-electro-mechanical systems (MEMS), spatially selective photothermal catalysis, nanoscale phase transition manipulation, and super-resolution photothermal therapy.

在纳米尺度上控制和操纵温度对于推进光热疗法、纳米尺度化学反应和微/纳米器件等应用具有重大的前景。然而，目前的温度调节方法主要依赖于连续可调的光学参数（例如，波长和偏振），这限制了离散和数字可寻址的控制状态，导致定制局部温度分布的自由度不足。光的轨道角动量（OAM）为光-近场热相互作用提供了一个新的视角，但其调节纳米尺度空间温度分布的潜力仍未被探索。在此，我们证明了涡旋光束的OAM对纳米尺度热场的独特调节作用。通过调整螺旋相位因子eilφ表征的涡旋光束的相位分布，在等离子体结构中诱导出明显的空间不对称温度分布和多个局部温度逆温。通过对涡旋光束关键参数（拓扑电荷l、波长和偏振方向）的协同调制，实现了亚波长空间分辨率下热近场分布的多自由度重建，其中升温比在0.6-1.7范围内可调。这项工作不仅为热调节提供了离散的和数字可寻址的控制状态，而且拓宽了对光热场相互作用的理解。为实现对局部热分布的多维远场光控制提供了指导，为微机电系统（MEMS）、空间选择性光热催化、纳米级相变操纵、超分辨率光热治疗等前沿应用开辟了新途径。
