Here, we address this by developing a ligand-mediated colloidal strategy to produce freestanding CuCr2Te4 nanosheets with controlled thickness and robust room-temperature ferromagnetism. Unlike substrate-dependent methods like chemical vapor deposition (CVD), our approach leverages facet-selective ligands to drive a Cu1.43Te-to-CuCr2Te4 cation exchange pathway, enabling anisotropic growth of ultrathin nanosheets with preserved cubic close-packed order. Mechanistic studies reveal that oleyl alcohol stabilizes (111) facets during the transformation, suppressing strain and phase impurities (e.g., Cr2Te3) while ensuring ambient stability. Magnetic force microscopy (MFM) and magneto-optical Kerr effect (MOKE) measurements confirm a Curie temperature (TC) above 300 K for thin nanosheets. Density functional theory (DFT) reveals that Cu doping enhances Cr-3d/Te-5p hybridization, leading to an increased spin-polarized density of states near the Fermi level, which in turn strengthens ferromagnetic exchange interactions. By decoupling synthesis from substrates and resolving growth pathways, this work establishes a scalable route to air-stable 2D magnets, advancing spintronic materials design with tunable anisotropy and thickness-dependent functionality.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147889185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This directly leads to reported perovskite polycrystalline wafer X-ray detectors still rely on external voltage bias, resulting in high energy consumption and limiting integration potential, though the simply-prepared polycrystalline wafers are promising candidates for advanced X-ray detection. Here, oriented ferroelectric wafers made of two-dimensional biaxial perovskite ferroelectric EA4Pb3Br10 (EA = ethylamine) were acquired, enabling self-driven X-ray detection. The EA4Pb3Br10 ferroelectric wafer exhibits well-oriented (0k0) planes, with four equivalent polarization directions distributed, leading to macroscopic spontaneous polarization in the polycrystalline state. Consequently, a switchable open-circuit voltage of 0.30 V was obtained under the irradiation, enabling impressive self-driven X-ray detection performance, including a remarkable sensitivity of 203.3 μC Gy-1 cm-2, a low detection limit of 17 nGy s-1, and the great operational reliability. The sensitivity further reaches a high value of 3779.2 μC Gy-1 cm-2 at 100 V mm-1, which surpassed many reported perovskite polycrystalline wafers. To our knowledge, this work represents the first realization of self-driven X-ray detection in the perovskite wafer family, offering an available strategy for the simply acquired self-driven radiation detectors.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SWNTs contribute to the control of aerogel morphology and significantly improve its mechanical toughness. The prepared aerogel has a bulk density of 9.13 mg/cm3 and excellent absorption properties with a minimum absorption peak of -64.5 dB and an effective absorption bandwidth(EAB) of 9.14 GHz. Through experimental comparison and time-domain finite integration calculation, the effect of oriented porous structure on the electromagnetic loss mechanism and performance was elucidated, which can be used for porous wave-absorbing materials.

However, inadequate textile-wettability, shielding-induced secondary pollution, and limited thermoregulation still impede their further multifunctional personal protection under extreme temperatures. Herein, we developed an electroactive hydrogel ink by combining MXene with PVDF polymeric matrix, and then impregnated onto the CFs to construct MX-PV-CF. The self-assembled PVDF layer modulates the MXene surface work function by forming a core-shell nanostructure, significantly improving its electro-thermal-magnetic properties. This PVDF-induced low work-function endows MX-PV-CF with remarkable multifunctionalities: 26 dB absorption-dominant electromagnetic radiation protection, high electro-thermal conversion, and a low mid-infrared emissivity (0.65). Mechanistically, the phase transitions of PVDF facilitate efficient heat dissipation, contributing to superior infrared-thermal-shielding. Consequently, MX-PV-CF provides excellent extreme temperature protection, maintaining a human-comfortable temperature (10-40°C) in extremely cold and hot environments. This work enables scalable wearable protection based on MXene-work-function-engineering under extreme temperatures, advancing intelligent protective material technology.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 5","pages":"94908291-94908291"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147887320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review provides a comprehensive overview of obesity, its associated comorbidities, and the limitations of conventional treatments. We explore the complex relationship between obesity-induced inflammation, immune dysregulation, and the pivotal role of adipose tissue macrophages (ATMs). Chronic low-grade inflammation in adipose tissues (AT) is a key driver of insulin resistance and metabolic dysfunction. As ATs expand, they undergo significant changes, including increased immune cell infiltration, particularly macrophages (MΦs), which shift from an anti-inflammatory towards a pro-inflammatory phenotype. This review aims to advance the understanding of immunomodulatory strategies by examining MΦ polarization and AT browning as promising therapeutic approaches. We focus on nanoparticles (NPs)-based strategies for immunomodulation, highlighting innovative engineering approaches designed to target the inflammatory pathways underlying obesity. By addressing these mechanisms, this review provides valuable insights into mitigating obesity-associated inflammation and related metabolic disorders, paving the way for novel therapeutic strategies in the fight against the global obesity epidemic.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"18 12","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12834562/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146058501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These features highlight the urgent need for ultrasensitive and non-invasive diagnostic methods. Pro-gastrin-releasing peptide (proGRP) has emerged as a highly specific biomarker for SCLC. However, existing detection techniques are often limited by long assay times and insufficient sensitivity. In this study, we developed a new electrochemical aptasensor based on two-dimensional high-entropy alloy nanosheets (HEANSs) for ultra-precise detection of ProGRP. The HEANSs were synthesized via a salt-templated method, which enabled precise control over composition, enhanced catalytic activity due to lattice distortion, and a uniform nanosheet morphology with high surface area. The HEANSs were functionalized with polydopamine (PDA), thereby introducing a variety of reactive functional groups that improved biocompatibility and markedly enhanced the efficiency of aptamer immobilization. This synergistic design achieved a broad linear detection range from 10 pg/mL to 100 μg/mL, an ultra-low limit of detection (LOD) of 0.874 pg/mL (S/N = 3), and excellent reproducibility with a relative standard deviation (RSD) of 1.78%. Moreover, the sensor retained 3.75% of its initial signal after nine days of storage, demonstrating exceptional stability. This pioneering HEANSs@PDA-based aptasensor provides a scalable and versatile platform for ultrasensitive biomarker detection, holding significant potential for early cancer diagnosis, real-time clinical monitoring, and precision medicine applications.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908352.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a multi-resolved imaging strategy, combining in situ electrochemiluminescence (ECL), photoinduced ECL, and photoluminescence imaging modes with ex situ scanning transmission electron microscopy (STEM) analysis, was employed to provide comprehensive insights into the dynamic heterogeneous relationship between catalytic activity, carrier behaviors and active sites on 2D semiconducting materials. By investigating pristine and annealed monolayer MoS₂, we establish a direct link between the distribution of specific defect types and their unique influence on catalytic activity and carrier behavior. We’ve identified molybdenum vacancies (VMo) as bifunctional active sites for both EC and PEC OER, while sulfur vacancies (Vs), while not primary catalytic centers, uniquely enhance PEC efficiency.

This antagonistic interplay constitutes a Li+–F- electronic seesaw effect; thus, the incorporation of both ions into NiFe–LDH on nickel foam (Li,F–NiFe–LDH/NF) optimizes the electronic structure, resulting in superior OER and HER activities with overpotentials of 201 and 104 mV, respectively.
