In this work, MOF-545@PANI composites have been synthesized by adsorbing aniline molecules onto the surface of MOF-545 and performing in-situ oxidative polymerization to grow polyaniline (PANI). The PANI shell formed on MOF-545 not only protects the MOF-545 framework during carbonization but also enhances electrical conductivity and specific surface area. Additionally, the carbon shell formed from PANI after high-temperature treatment effectively addresses the issue of its redox peaks interference within the potential window, which is conducive to the accurate display of the redox current signals of tert-butylhydroquinone (TBHQ). Using MOF-545@PANI-800, a high-performance portable sensor for TBHQ has been developed with a detection range of 0.03 to 100.0 μM and a limit of detection (LOD) of 12.6 nM. This portable sensor accurately detects TBHQ in food and environmental water samples, with results comparable to HPLC. Density functional theory (DFT) has been used to study the adsorption energy and charge density distribution of TBHQ on both MOF-545 and MOF-545@PANI-800. This breakthrough electrochemical detector provides valuable opportunities for creating smart, efficient, and portable monitoring solutions.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"44 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142936504","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}

Subsequently, the impacts of low-light intensity (250 – 5500 Lux) on the photovoltaic performances of the DTENG-Si TSC with and w/o droplets impingement are systematically investigated, demonstrating the TSC could break through the bottleneck of the limited power conversion efficiency (PCE) of individual Si SC under low-light condition. A PCE of 21.71% can be achieved by the DTENG-Si TSC, providing a relative enhancement of 10.65% over the bare Si SC under standard AM 1.5 G solar irradiation at 100 mW cm-2.

Significant challenges remain in enhancing the power-generation efficiency of TENG. Here, an innovative Auxetic Triboelectric Nanogenerator (Auxetic-TENG) incorporating metamaterials with Negative Poisson’s ratio was designed to address the challenges of integrated low power-density and deformation mismatch in complex bending operations. The Auxetic-TENG employs a concave horseshoe-shaped silicone elastomer with synclastic effects as the outer framework of the positive triboelectric layer. The positive triboelectric layer comprises aminated collagen-aggregates composite, while the negative triboelectric layer is constructed from polydimethylsiloxane. The positive and negative triboelectric layers are further enhanced by microstructured convex surface designs, boosting the overall power output. The synclastic effects of the framework induce lateral displacement under uniaxial stretching, significantly improving both electromechanical conversion efficiency and conformability to the human body’s joint-bending. Surprisingly, the Auxetic-TENG derived wearable device achieves an open-circuit voltage of 47 V, which is 2.2 times higher than that of conventional contact-separation TENGs. Additionally, the power density of the Auxetic-TENG can achieve 145.3 mW·m⁻².

The Mn-doped Ni nanoparticles encapsulated in SSZ-13 pores exhibited a CO2 conversion of 84.62% and CH4 selectivity of 98.02%, approaching the thermodynamic limit of CO2 methanation and surpassing the previously reported state-of-the-art catalysts.

This study demonstrates that biomass-derived melanin-like nanoparticles (MNPs) function as an eco-friendly compatibilizer, enhancing phase compatibility in PLA/PBS blends.

Triboelectric performance also improved significantly, with the charge density increasing by 1.78 times, reaching 414.88 μC/m². Under UV exposure, the MNP-modified blends exhibited strong stability, with only a 9% reduction in performance after 7 days. MNPs promoted a controlled degradation rate that can accelerate under certain conditions, ensuring the composite remains stable during regular use and maintains biocompatibility. When used in wearable motion sensors, M-TENGs displayed consistent and strong signals, accurately detecting a range of human movements, including walking, jogging, and jumping.

The unique integration of carbonized melamine foam (CMF) with magnetic high-entropy alloy (HEA) nanosheets not only provides a lightweight framework but also enhances EMW attenuation due to the inherent lattice distortion and high-entropy effects of the HEA nanosheets. This combination achieves a remarkable minimum reflection loss (RL) of -74.86 dB and an effective absorption bandwidth (EAB) of 7.94 GHz with only 12 wt% filling, maintaining a low material density. Additionally, the composite exhibits excellent thermal insulation and hydrophobicity, featuring thermal camouflage and a water contact angle of 130°, ensuring device stability under extreme conditions.
