The present study demonstrates that pEVs act as potent nanocarriers that aggravate transfusion-related acute lung injury (TRALI) through activation of the Cd36-Fyn signaling pathway in macrophages. Integrated single-cell RNA sequencing and mechanistic analyses demonstrated that pEV administration selectively induced M1 macrophage polarization and amplified pulmonary inflammation. Cd36 was markedly upregulated in the Fn1+ macrophage subset, serving as the receptor that mediates pEV uptake and Fyn activation. Molecular and pharmacological inhibition of Cd36-Fyn signaling significantly attenuated pro-inflammatory cytokine expression, lung tissue damage, and mortality in vivo. These findings elucidate how nanoscale platelet vesicles reprogram macrophage responses and disrupt immune homeostasis, providing a mechanistic framework for understanding TRALI progression. Identification of the Cd36–Fyn axis as a molecular link between nanovesicle signaling and immune dysregulation highlights new therapeutic opportunities for transfusion safety and nanomedicine-based interventions.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 5","pages":"94908388-94908388"},"PeriodicalIF":0.0,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908388.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917181","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}

However, integrating high-performance tensile and pressure sensing into a single yarn to monitor comprehensive human activities remains a significant challenge. In this work, we present a dual-model strain-sensing nanofiber yarn fabricated by self-shrinking MXene-coated carbon black/thermoplastic polyurethane (MXene@CB/TPU) composite nanofiber films into Janus-structured slim scrolls, followed by double twisting using internal stress. Carbon black doping enables conductive nanofibers to bridge propagated cracks in MXene coating, forming a synergetic conductive network. This structure enhances the yarn's tensile sensing linearity from 0.810 to 0.994, while achieving a broad range of 106% with a gauge factor of 56. The self-shrunk and double-twisted architecture also provides dual-stage pressure sensitivity, endowing the yarn with an ultrahigh pressure-sensing range of up to 10 MPa, a sensitivity of 17.74 MPa-1, and a linearity of 0.997 (0~3 MPa). Furthermore, the yarn exhibits excellent washability (> 30 ultrasonic washing cycles) owing to crosslinked nanofibers that protect the MXene layer. We demonstrated the practical applicability of this yarn by stitching it into various smart textiles, which successfully detected both tensile and pressure signals from full-range human activities. As a proof-of-concept, a smart waist support developed using this yarn can monitor both dynamic and static waist status. This work achieves high-performance dual tensile and pressure sensing in smart textiles using a single yarn, opening new pathways for advanced wearable electronics.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908397.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903450","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 work proposes a unique preparation strategy combining solution blow spinning, spraying and hot pressing to develop multi-layered LM/PAN films with well-disperse LM nanodroplets on polyacrylonitrile (PAN) fiber films. The in-plane thermal conductivity of the films reached 7.768 W×m⁻¹×K⁻¹, and 3.623 W×m⁻¹×K⁻¹ along the thickness direction, indicating 80 and 58 times higher than that of pure PAN film, respectively. The high thermal conductivity quickly dissipated the generated heat by electronic devices, helping address the issue of heat accumulation. In the X-band (8.2-12.4 GHz), the shielding effectiveness (SET) of the films was as high as 79.52 dB to effectively block electromagnetic wave interference. Based on the excellent performance of the films, a single-electrode triboelectric nanogenerator (HPP LM/PAN-TENG) pressure sensor was further developed. This sensor exhibited high sensitivity to pressure changes and accurately monitored both large and subtle human motions. More importantly, the sensor accurately captured the subtle features of early gait abnormalities with Parkinson's disease, providing evidences for early diagnosis. The LM/PAN films are easy to prepare and can be produced at a large scale, with a broad application potential in fields of thermal management of electronic devices, electromagnetic protection, and wearable sensing.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908430.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147899304","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}

Modifying the insulating base materials through filling to enhance their corona resistance is a critical measure to ensure the safe operation of electrical equipment. This article proposes, for the first time, a distinct modification strategy of cage-like octa(aminopropyl) silsesquioxane (8NH2-POSS) particle toward the molecular structure of polyimide. This particle can form covalent bonds with both the main chains and side chains of polyimide (PI) during polymerization, thereby enhancing the flame retardant, mechanical and corona resistance of the polyimide matrix. Benefiting from the organic-inorganic hybrid structure, the POSS with amino groups provides interfacial compensation for PI at the molecular structural level. The power frequency breakdown strength of the 8NH2-POSS main-chain grafted PI composite film (8NMP/PI) is increased by 31.5%, and the corona discharge inception voltage is enhanced from 1.93 to 2.13 kV. And the average corona resistance time of 8NMP/PI is prolonged from 305 to 498 s, which is 63.3 % higher than the pure PI film. Meanwhile, its excellent interface effect improves the flexibility of the composite film, with the average tensile strength increased by 17.6% and the elongation at break by 16.2 %. All composite films have reached UL-94 V-0 rating. This work provides valuable reference for developing high-performance polymer composites for applications in large-scale electrical devices.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908433.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147901749","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}

Herein, the bimetallic single-atom NiCo/NC-TA electrocatalyst with the unclosed hollow morphology was constructed by the modification of precursor. Within this structure, hierarchical porous architecture, and surface hydrophilicity synergistically enhance the exposure and accessibility of active sites. Theoretical calculations confirm that the introduction of Ni facilitates electron transfer from Co sites, resulting in a downshifted d-band center. This electronic configuration effectively mitigates the over-adsorption of reaction intermediates, thereby reducing the energy barriers for both reactions. In alkaline ORR test, NiCo/NC-TA outperformed Pt/C-20% in both activity and stability, achieving a half-wave potential of 0.896 V and retaining 98% of the current after 10-hour durability testing. Moreover, NiCo/NC-TA-based Zn-air batteries delivered a high open-circuit voltage of 1.49 V, a specific capacity of 764.1 mAh g−1., and long-term cycling stability. Notably, the catalyst also exhibited enhanced HER activity, with a low overpotential of 92 mV in alkaline media, matching Pt/C-20% performance at a current density of 120 mA cm−2.

However, flame-retardant materials are often hydrophilic, causing them to easily dissolve in high-humidity environments, thereby significantly limiting their durability. Thus, the integration of water  repellency and flame retardancy into a single coating is ideal for developing durable, flame-retardant materials. In this study, a robust skin-inspired double-layer coating was fabricated by using spray coating. An intumescent flame-retardant “dermis” layer, comprising ammonium polyphosphate (APP), polydopamine (PDA), and 1-[3-(trimethoxysilyl)propyl]urea (UPTMS), provides the primary heat insulation and flame retardancy functions. A superhydrophobic “epidermis” layer, constructed using silicone nanofilaments (Si NFs), poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), and Triethoxy-1H,1H,2H,2H-heptadecafluorodecylsilane (PFDTS), protects flame-retardant materials in moist conditions. Owing to its intumescent effect, the obtained coating demonstrated excellent flame retardancy, with the fire self-extinguishing immediately after the removal of flame source. It achieves a limiting oxygen index (LOI) of 85.3% and significantly decreases the peak heat release rate (PHRR) and the fire growth index (FGI) of 59.20 kW·m-2 and 0.789 kW·m-2·s-1, respectively. The epidermal layer demonstrated outstanding superhydrophobicity and remarkable mechanical stability, with the water contact angle remaining above 160° after 1000 bending cycles between 90° and 180°. Together with the facile spray-coating process, the biomimetic design of this intumescent flame-retardant and superhydrophobic coating provides a feasible and sustainable strategy for constructing durable fireproofing materials.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NR.2026.94908394.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332539","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}
