Here, this study presents novel dual-plasticizer strategy by synergistically incorporating dibutyl adipate (DBA) as the primary plasticizer with propylene carbonate (PC) and ethylene carbonate (EC) as high-dielectric secondary plasticizers to polyvinyl chloride (PVC). The dual-plasticized PVC-gel achieves superior dielectric loss and dissipation factor exceeding 3 × 103 and 295, facilitating efficient dielectric heating. The heater simultaneously exhibits exceptional stretchability (300%) and optical transparency (>90%) for maintaining visual aesthetics. The heater reaches over 60 °C at an operating voltage (350 V) with rapid heating rate of 0.76 °C s−1 and exhibits excellent power efficiency (1.015 W cm−2). Moreover, it demonstrates uniform heat distribution and achieves saturation temperature within 1 min at every voltage. The heater exhibits remarkable thermal stability with sustained performance during 20000 s and maintains stable heating performance without temperature degradation under stretching. These capabilities enable both therapeutic heating and thermal sensing functionalities, demonstrating adaptive wearable applications while maintaining conformal contact and consistent heating under complex wrist movements. Furthermore, this heater implements thermal sensing system capable of gesture recognition, establishing potential for next-generation wearable electronics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"20 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, eight 2D flaky and 1D acicular plant biomasses is systematically compared to synthesize pristine carbon, N-doped carbon, and cobalt/graphitic carbon for Fenton-like peroxymonosulfate (PMS) activation. Biomass pyrolysis under 5% NH₃ generates surface N-doped amorphous carbon, facilitating a selective electron transfer pathway (ETP), where high N incorporation, specific surface area, and atomic-level control over O groups synergistically enhance its efficiency. While COOH groups contribute positively, excessive defects and C═O groups hinder ETP performance. Notably, compared to 2D biomass, 1D acicular biomass induces tubular carbon with lower C═O content, promoting the ETP regime. 2D flaky biomass facilitates Co nanoparticle incorporation in cobalt/graphitic carbon, where high contents of N, Co, defects, and oxygen groups (C═O/C─O/COOH) enhance sulfate radical (SO4•−)-dominated catalysis, whereas excessive sp2 C (>75–80 at.%) negatively affects performance. Through structural characterization, mechanistic analysis, and quantitative linear fitting correlations, this study identifies biomass-derived key active site interactions governing electron transfer and SO4•−-driven oxidation mechanisms. These insights establish a framework for sustainable, biomass-structure-driven carbon design for environmental catalysis.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"588 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a pH-responsive core-shell nanosilver platform (PST/Ag) is reported that exploits structural disparities between bacterial and mammalian cells to achieve dual therapeutic effects. The PST/Ag selectively adheres to bacterial membranes and rapidly releases Ag+ via pH-responsive dissolution in the acidic infection niche, achieving multimodal bactericidal effects while mitigating resistance risks. Crucially, PST/Ag minimizes off-target toxicity through disparity-driven cellular trafficking: reduced endocytosis in skin cells confines Ag+ release within lysosomal compartments, where Ag+ is dynamically reduced to secondary nanoparticles, ensuring sustained sub-toxic Ag+ flux. This controlled release triggers a Hormesis effect—low-dose Ag+ activates protective autophagy, synergizing with polyserotonin shell-derived metabolites to enhance fibroblast migration, angiogenesis, and extracellular matrix remodeling. In murine-infected wound and rabbit wound models, PST/Ag outperforms conventional silver nanoparticles by concurrently eradicating bacteria, accelerating re-epithelialization, and preventing scar formation. This “defense-regulation” dual modality—precision antibacterial coupled with microenvironment reprogramming—redefines nanosilver-based wound management paradigms, offering a translatable solution for complex tissue repair.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"10 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the single catalytic approaches relying on either piezoelectric or pyroelectric effect compel ferroelectric materials to yield inadequate ROS, ultimately dampening the sterilization speed and efficiency. To address the daunting issue, a dual catalytic membrane composed of BaTiO3/MgO2 and electrospun poly (lactic-co-glycolic acid) nanofibers is devised, which integrates both pyroelectric and piezoelectric effects of BaTiO3 by encapsulating polydopamine. The dual catalytic membrane potentiates polarization charge generation under ultrasound and near-infrared stimulation. Subsequently, the polarized charge participates in the generation of germicidal ·OH by reacting with H2O2 from MgO2, thus achieving rapid antimicrobial activity. More intriguingly, in vitro and in vivo experiments have demonstrated that the dual catalytic membrane substantially facilitates cell proliferation and promotes the regeneration of infected wounds through bacterial slaughter, NF-κB inflammatory pathway inhibition, pro-angiogenesis, as well as collagen deposition. As envisaged, such a proposal provides a bright prospect for ferroelectric materials in addressing acute infections and advancing the remediation of refractory infected wounds.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"11 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Ksp-regulated electrochemical etching strategy is first proposed to solve this challenge by exploiting the dramatic solubility difference between BaSO4 and Co/NiSO4. The thermodynamic selectivity enables the precise construction of BaSO4 nanodot-anchored NiCo-LDH heterostructures (BS@CN-LDH) within a rapid minute-scale process, achieving atomic-level control over heterointerface architecture. Density functional theory (DFT) calculations coupled with UPS analysis reveal a strong built-in electric field (BEF) at the heterointerface (ΔΦ = 0.70 eV), driving interfacial charge redistribution of 0.013 e from NiCo-LDH to BaSO4. The optimized BS@CN-LDH electrode material exhibits a high specific capacity of 450.5 mAh g−1 at a current density of 2 mA cm−2, maintaining 83.3% excellent cycling stability after 10 000 cycles. Moreover, the as-fabricated BS@CN-LDH//rGO-Zn AAZB cell achieves a record energy density of 747.9 Wh kg−1 at a power density of 0.27 kW kg−1, surpassing most reported zinc-based energy storage devices.

STM topography reveals triangular clusters of Ta atoms embedded within W-rich regions of TaWSe2. These clusters exhibit a consistent shape and an orderly arrangement throughout the surfaces.

However, the accumulation of inorganic components in the inner solid electrolyte interphase (SEI), caused by substantial sodium salt decomposition, impedes the kinetics of Na+ interphasial transport. Here, a NaF/Na2CO3-rich heterostructured SEI, with significantly improved Na+ diffusion kinetics, is proposed in a dilute ether-based electrolyte. The heterostructure provides additional Na+ transport pathways through Na2CO3 and along the NaF/Na2CO3 interface. The interfacial synergy effect between Na2CO3 and NaF effectively reduces the Na+ diffusion energy barrier and improves the mechanical robustness of SEI, ensuring facilitated interphasial kinetics. Consequently, the hard carbon (HC) anode delivers a high reversible specific capacity of 238 mAh g−1 at −40 °C and an impressive cycling stability at −20 °C with a capacity retention of 89.67% after 1800 cycles at 1 C.

The buried interface engineering is considered the most effective strategy for achieving high-performance PSMs. Herein, the organic thiazole molecule 2-Cyaniminothiazolidine (CTH) is introduced, which possesses multiple active sites, to modify the buried interface of PSCs. The introduction of CTH can effectively accelerate the nucleation and delay the crystal growth of perovskite compared to monofunctional group additives. In addition, the multisite functional group in CTH passivates deep energy level defects and shallow energy level defects in the perovskite films. These results can reduce interfacial voids and produce high-quality perovskite films. Consequently, the champion devices prepared under ambient conditions achieve efficiencies of 24.31% for a small area (0.07 cm2) and 22.09% for a large area (1 cm2), respectively. The inverted PSMs with an aperture area of 48 cm2 achieve an impressive efficiency of 20.76%, indicating a teeny efficiency loss from 1 to 48 cm2.
