Redox-enhanced electrochemical capacitors (redox ECs) address this limitation by incorporating redox-active electrolytes, enabling Faradaic charge storage. Bromide is a promising catholyte due to its high reduction potential, excellent solubility, and low cost. However, the generation of corrosive Br2 and the cross-diffusion of soluble polybromides result in suboptimal cell efficiency including severe self-discharge and reduced cycle life. Although solid complexing agents have been used to suppress polybromides' cross-diffusion, this approach necessitates water, which inherently limits electrochemical and thermal stability. Here, a hydrated deep eutectic solvent (HDES) electrolyte is developed by combining tetrabutylammonium bromide (TBAB) with ethylene glycol. This HDES system effectively utilizes the multifunctional roles of TBAB: the bromide anion functions as a catholyte, while the TBA cation suppresses polybromides' cross-diffusion as a built-in solid complexing agent. Critically, unlike previous studies that focus on minimally hydrated DESs, this system leverages the hydrophobic effect of TBAB to accommodate higher water content, addressing challenges inherent to DESs while maintaining superior electrochemical and thermal stability. The optimized HDES-50 electrolyte, containing 50 wt.% water, provides a robust and efficient solution for advanced redox ECs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"35 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713786","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, current sensors often struggle to meet these requirements, as they usually rely on a single compression mechanism. In this study, a microvilli-microstructures sensor is reported which is capable of tracking ultra-broad-range pressures based on a synchronous-compression mechanism. The synchronous-compression mechanism includes: i) the increase of microvilli-induced electron-transfer, ii) the increase of microstructure contact area, and iii) the decrease of multi-walled carbon nanotubes spacing. At the high-pressure stages, the mechanisms contribute synchronously to changes in resistance. Hence, this sensor can measure a 5 kPa pressure change under the extremely high- pressure (750 kPa) conditions of meniscus simulation, where the commercial sensor fails. This sensor exhibits a high sensitivity of 58.88 kPa−1, an ultra-broad working range from 50 Pa up to 782.5 kPa, a rapid response time of 9 ms, and a long-duration (under 250 kPa pressure, cycling for 10,000 times). This flexible pressure sensor also shows versatility and potential for various applications. The synchronous-compression mechanism proposed here can inspire future designs of high-performance flexible sensors.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"60 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713564","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, different from most studies that focus on modifying elastomers such as polyacrylates and silicones, the study designs a prestretch-free dielectric elastomer based on hydrogenated carboxylated nitrile butadiene rubber to reach a record-high energy density (564 J kg−1) and power density (5641 W kg−1), ≈15 times greater than natural muscle and three times greater than the state-of-the-art dielectric elastomers. This excellent performance arises from the synergistic polarization enhancement and strain stiffening overcoming the inherent trade-offs between electrical and mechanical properties, simultaneously endowing the elastomer with an extremely high dielectric constant (ɛr = 17, 100 Hz), ultralow mechanical loss (tan δm = 0.04@1 Hz), and large electrical breakdown strength (105 V µm−1). The assembled 40-µm-thick actuator lifts a 200-g load with over 20% strain and maintains a stable power density of 4780 W kg−1 for 50 000 cycles. Furthermore, the actuators demonstrate diverse applications, including serving as biceps artificial muscles to achieve a 90° rotation angle at a speed of 360°/s and actuating a soft robot carrying a load 20 times its weight.

Herein, an inert heteroatom substitution strategy is developed to activate adjacent dual-active-sites for boosting photocatalytic reduction of diluted CO2. As a proof of concept, Co2+δ/Ni2+ζ dual-active-sites in layered double hydroxides (LDHs) photocatalyst with high activity is interspaced and regulated by inert Al substitution. The corresponding elementary reaction step is optimized, where the Ni2+ζ site shows high activation of CO2 reduction and weak absorption of *CO, whilst the Co2+δ site facilitates water oxidation. Most importantly, the produced *H on the Co2+δ site is synchronized with the formation of *COOH on the Ni2+ζ site, which synergistically lowers the energy barrier (*CO2 to *COOH) of the rate-determining step. Resulting CoNiAl-LDHs photocatalyst attains nearly 100% selectivity with a production rate of 784 µmol g−1 h−1 toward diluted CO2 reduction to CO, representing the best performance reported to date. This work delivers a feasible strategy via inert site substitution to activate proximate dual sites, which provides fundamental guidance to design photocatalysts for CO2 reduction.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"98 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723706","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}

Herein, a novel electrochemiluminescence (ECL) sensing platform is constructed through the in situ encapsulation of aggregation-induced emission (AIE) molecules, tetraphenylethylene, within metal-organic frameworks (NH2-MIL-88). These frameworks are uniquely enriched with atomically dispersed active sites that serve as nanoconfined co-reactant accelerators. This innovative design leads to the creation of an integrated AIE nanoconfinement reactor. Within this reactor, the co-reactant accelerators catalyze co-reactants into reactive species (RS) in situ, facilitating direct interaction with AIE molecules in a spatially confined composite. Density functional theory calculations and in situ electrochemical electron paramagnetic resonance demonstrate that the ECL enhancement is attributed to the localized amplification, where the nanoconfined space formed by coordination self-assembly alters the activation energy barriers and improves the absorption capacity for catalyzing K2S2O8 into SO4·- and OH·−. Additionally, by utilizing MATLAB-mediated image enhancement technology and deep learning algorithms, a smartphone-adopted self-reporting AIECL imaging system is designed to achieve an accurate and intelligent analysis of cardiac troponin I (cTnI).

To address these drawbacks, the newly-emerging low-melting-point bismuth-based alloys as injectable bone implants, combined with clinically applied polymethyl methacrylate (PMMA) bone cement are proposed here to innovatively design the multifunctional bismuth-PMMA composites (BPCs) for effective bone repair. The as-prepared BPCs offer excellent injectability, enhanced mechanical properties (≈252% increase in compressive strength), and favorable magnetothermal effects, enabling minimally invasive, in situ bone molding via easygoing injection for orthopedic surgeries. The introduction of PMMA in BPCs significantly improves mechanical strength while maintaining the injectability of bismuth alloys, and reduces exothermic heat during curing to prevent thermal damage to bone tissue. In vivo experiments demonstrate that under an alternating magnetic field, BPCs exhibit outstanding tumor cell killing capability and inhibit osteosarcoma growth through efficient magnetic hyperthermia. Further, long-term in vivo implantation results coupled with histological analysis display stable bone filling and evident bone regeneration, attributed to the collaborative efficacy of BPC implant and mild magnetothermal therapy.
