However, information about is scattered. Therefore, we systematically map the evidence on detected migrates extracts of contact materials provide an overview available hazard biomonitoring data. Based FCCmigex database, 68 have been identified various materials, including paper, plastic, coated metal, by targeted untargeted analyses. 87% these belong perfluorocarboxylic acids fluorotelomer-based compounds. Trends chain length demonstrate that long-chain perfluoroalkyl continue found, despite years global efforts reduce use substances. We utilized ToxPi illustrate data for only 57% packaging. For those which toxicity testing has performed, many adverse outcomes reported. The knowledge gaps presented here support international proposals restrict as a group, protect health.

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals widely used in consumer industrial products due to their unique physicochemical properties. However, persistence bioaccumulative potential pose significant environmental human health risks. This review focuses on the use of non-invasive matrices-urine, hair, nails-for biomonitoring PFAS, highlighting key findings from scientific studies. While urine offers a practical option, its limited sensitivity for long-chain PFAS requires further analytical advances. Hair nails have demonstrated biomonitoring, with higher detection frequencies concentrations certain compared urine. The variability levels across studies reflects differences population characteristics, exposure sources, geographic regions. emphasizes need standardized methods, expanded studies, complementary matrices enhance accuracy reliability assessment.

Silicon dioxide (SiO2) is a prominent candidate for radiative cooling applications due to its low absorption in solar wavelengths (0.25–2.5 µm) and exceptional stability. However, bulk phonon-polariton band results strong reflection peak the atmospheric transparency window (8–13 μm), making it difficult meet requirements sub-ambient passive cooling. Herein, we demonstrate that SiO2 micropillar arrays can effectively suppress infrared at 8–13 μm enhance emissivity by optimizing array structure. We created pattern with height, spacing, diameter of approximately 1.45 μm, 0.15 0.35 respectively, on top substrate using reactive ion etching. The resulting surface phonon coupling led an increase thermal from 0.79 0.94. Outdoor tests show cooler optimized generate average temperature drop 5.5 °C throughout daytime underneath irradiance 843.1 W m−2 noon. Furthermore, endow remarkable hydrophobic properties, attributed formation F/C compounds introduced during etching process. Finally, also replicated onto industrial optical reflectors (OSRs), demonstrating similar hydrophobicity enhancements. Our findings revealed effective strategy modifying management features durable layers, which be harnessed cool OSRs other sky-facing devices.

Abstract In recent years, an increasing number of passive radiative cooling materials are proposed in the literature, with several examples relying on use silica (SiO 2 ) due to its unique stability, non‐toxicity, and availability. Nonetheless, bulk phonon‐polariton band, SiO presents a marked reflection peak within atmospheric transparency window (8‐13 µm), leading emissivity decrease that poses challenge fulfilling criteria for sub‐ambient cooling. Thus, latest developments this field devoted design engineered photonic structures, increase potential coolers. This review seeks identify most effective fabrication strategies emitters by evaluating their efficacy, as well scalability, providing in‐depth analysis fundamental principles, structural models, results (both numerical experimental) various types

Recent developments in hydrocarbon-based proton exchange membrane fuel cells have significantly narrowed the performance gap compared to state-of-the-art using perfluorosulfonic acid ionomers (PFSA). However, balancing protonic resistance and gas transport catalyst layer remains a challenge at low humidity. This study investigates its components sulfonated phenylated polyphenylene-based layers various limiting current methods. Results show that increasing dry ionomer carbon (I/C) ratio from 0.2 0.4, measure catch up with of PFSA-based layers, increases cathode by 28 %. The data suggest strong correlation between local IEC. A high IEC is beneficial for through film. volume fractions dominated I/C independent interfacial resistance. Furthermore, hydrocarbon ionomer, such as Pemion ® PP1-HNN4–00-X (IEC = 2.5 meq g −1 ), not only exhibits resistance, but also suppresses excessive swelling, which typically occurs during operating conditions where liquid water forming.
