    Global, regional, and national burden of household air pollution, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021 by Fiona B, Bennitt

    Published 2025
    “…FindingsIn 2021, 2·67 billion (95% uncertainty interval [UI] 2·63–2·71) people, 33·8% (95% UI 33·2–34·3) of the global population, were exposed to HAP from all sources at a mean concentration of 84·2 μg/m3. Although these figures show a notable reduction in the percentage of the global population exposed in 1990 (56·7%, 56·4–57·1), in absolute terms, there has been only a decline of 0·35 billion (10%) from the 3·02 billion people exposed to HAP in 1990. …”

    Anticoagulant activity of cellulose nanocrystals from isora plant fibers assembled on cellulose and sio2 substrates via a layer-by-layer approach by Mohan T.

    Published 2021
    “…In this study, we report the isolation of cellulose nanocrystals (CNCs) from Isora plant fibers by sulfuric acid hydrolysis and their assembly on hydrophilic cellulose and silicon-di-oxide (SiO2) surfaces via a layer-by-layer (LBL) deposition method. The isolated CNCs were monodis-persed and exhibited a length of 200-300 nm and a diameter of 10-20 nm, a negative zetapotential (34-39 mV) over a wide pH range, and high stability in water at various concentrations. …”

    An experimental study on achieving even-frosting for an air source heat pump using a novel dual-fan outdoor coil by Bai, Xiaoxia

    Published 2022
    “…Besides, as tTIAO values were decreased from 15 mins to 10 mins for both fans, and to 6 mins for Fan A and 8 mins for Fan B, heating/frosting operation duration was increased by 8.9% and 19.4%, respectively, at a higher and , as compared to those using the traditional single-fan outdoor coil. …”

    Numerical analysis of spatial distribution of carbon in methane dry reforming over supported nickel catalyst in a packed bed reactor by Ebrahimi, Parisa

    Published 2024
    “…The total carbon deposited was estimated to be around 18 g after 10,000 s of Time on Stream (TOS) at 650 °C. As the temperature increased, the total carbon deposition decreased, although this reduction became negligible beyond 850 °C. …”
