Through molecular engineering, we synthesized a methacrylated PO derivative (MPOEA) and a PA-based methacrylate monomer (GPA) to enable UV-induced crosslinking while maintaining low viscosity (<42 mPa·s) and near-complete C = C conversion (96.8%), ensuring structural integrity and print fidelity. Notably, the phosphate esters in GPA impart a synergistic flame-retardant mechanism, combining condensed-phase barrier formation and gas-phase radical quenching. Additionally, the material exhibits efficient TENG functionality, generating a stable output of 8 V at 3 Hz over 15,000 cycles, which underscores its suitability for self-powered sensors and wearable electronics.

Upon reaching the target area, the carriers break down to release the nanorobots, which then form swarms that can penetrate deeply into tumors. The nanorobots are designed to combine heat generation and drug releasing when activated by near-infrared irradiation, allowing precise and effective chemo-photothermal therapy.

Inspired by the exquisite recognition and self-adaptive mechanisms of biomolecules in nature, this study proposes a bioinspired binder strategy based on Hyaluronic acid to reconstruct the interfacial microenvironment of the cathode at the molecular level. The binder, with its rich multipolar groups and dynamic hydrogen-bonding network, effectively enhances the anchoring and adsorption of polysulfides. Meanwhile, the unique double-helix chain structure of Hyaluronic acid generates a “breathing mode” that realizes the selective capture and spatial redistribution of active materials, thereby effectively promoting the kinetic conversion and reaction reversibility of polysulfides. The high-sulfur-loading cathode (63.8 wt%) assembled based on this mechanism manifests exceptional electrochemical performance, with an initial discharge capacity of 1347.75 mAh·g⁻¹ at 0.2 C and a capacity decay rate of merely 0.1% per cycle at 3 C. Polysulfide shuttling and uneven dispersion are two challenges that hinder the commercialization of lithium-sulfur batteries. Here, hyaluronic acid is used as a binder to reconstruct the molecular structure of the cathode surface, leading to improved performance.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43246-025-00982-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147915232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we introduce an approach that exploits electrode-electrode synergy and in situ structural transformation to increase the ionic conductivity of an electrolyte within the electrochemical cell. This transformation is based on the formation of a Li2TiO3-Li2CO3 heterostructure electrolyte via the combination of a TiO2 semiconductor precursor, polystyrene spheres as the soft skeleton, and the lithium-based electrode LiNi0.8Co0.15Al0.05O2. The unique surface and interface of the heterostructure electrolyte enable the formation of long-range ion transport channels that lower electrode impedance, resulting in a superior ionic conductivity of 0.23 S cm−1 at 550 °C and a high-power density of 1239 mW cm−2. Our general method to form superionic electrolytes shows potential in fuel cell technologies. Achieving high ionic conductivity at reduced temperatures is important for electrochemical cell scale-up.

Traditional medical dressings, such as gauzes, serve merely as physical barriers and are insufficient to prevent bacterial adhesion and invasion. Herein, we present a composite nonwoven fabric dressing (PVA@HD5-myr) by covalently conjugating multi-bioactive human α defensin 5 derivative (HD5-myr) to polyvinyl alcohol (PVA). PVA@HD5-myr fibers are produced in one step by incorporating Tyzor®LA, a titanate coupling agent, into the spinning dope during the spinning process. The resulting PVA@HD5-myr demonstrates satisfactory antibacterial activity against multiple drug-resistant bacteria through adhesion and cell membrane disruption. Additionally, PVA@HD5-myr effectively inhibits biofilm formation on its surface, blocks bacterial invasion, and significantly promotes wound healing in vivo. This dressing also disrupts endotoxin release in skin wound environments, with favorable safety profiles both in vitro and in vivo assessments. Our findings suggest that PVA@HD5-myr is a promising candidate for next-generation clinical dressings, offering effective antimicrobial properties alongside wound protection. Medical dressings are typically not effective at preventing bacteria invasion, and act only as a physical barrier. Here, defensin-conjugated polymer fabrics are shown to be effective against antibacterial activity for various drug-resistant bacteria, by preventing cell adhesion and biofilm formation, while encouraging wound healing.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43246-025-00944-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal oxide semiconductor (MOS) based gas sensors are simple structures with low cost that are a promising approach for H2 detection. However, detection speed and selectivity of MOS-based sensors currently face great challenges. Herein, we design palladium single atoms (SAs) doped tin oxide (SnO2/Pdatom) for H2 detection. Actual sensing tests show an ultrafast response speed toward H2 (3s to 10 ppm H2), with detection limit of 50 ppb and superior selectivity. Using in-situ THz time-domain spectroscopy and density functional theory calculations, it proves that an extra energy band near Fermi level appeared in SnO2/Pdatom, and Pd SAs doped on SnO2 enhance signally concentration of free carrier in SnO2/Pdatom. Partial density of states reveals that coupling hybridization between Pd 4d orbital and O 2p orbital promotes electron injection from Pd 4d orbital into O π2p orbital, improving production of more O- ions on sensing surfaces. Consequentially, the sensing dynamics involving O- ions spillover at SnO2-Pdatom interface is discussed. Metal oxide semiconductor-based sensors are promising for hydrogen detection but their detection speed and selectivity are still limited. Here, a hydrogen sensor consisting of palladium single atom-doped tin oxide shows a response speed to hydrogen of 3 s and a detection limit of 50 parts per billion.","PeriodicalId":10589,"journal":{"name":"Communications Materials","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s43246-025-00865-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
