    Porous SiO<sub>2</sub> Nanofibers Loaded with CuO Nanoparticles for the Dosimetric Detection of H<sub>2</sub>S by Sebastian Werner (1519645)

    Published 2021
    “…As a concentration of 5 ppm is regarded as a level above which H<sub>2</sub>S is considered to be harmful, the materials show potential for H<sub>2</sub>S sensors with long-term stability. …”

    Nanoporous Silica Preconcentrator for Vapor-Phase DMNB, a Detection Taggant for Explosives by Coco Day (9121340)

    Published 2020
    “…The collection efficiency of pSiO<sub>2</sub> was calculated as approximately 20% of the total DMNB that passed over it in 30 min, at a concentration of 0.5 ppm in N<sub>2</sub> carrier gas. It had enhancement factors compared to the nonporous substrate of 12 and 16 for 0.5 and 4.1 ppm DMNB, respectively, under the same conditions. …”

    Transcriptomics-Driven Discovery of New Meroterpenoid Rhynchospenes Involved in the Virulence of the Barley Pathogen <i>Rhynchosporium commune</i> by Reynaldi Darma (20713741)

    Published 2025
    “…Infiltration of rhynchospenes into barley leaves resulted in strong necrosis, with rhynchospene B demonstrating the highest phytotoxicity and causing necrosis at a minimum concentration of 50 ppm. Silencing <i>rhyM</i> in <i>R. commune</i> WAI453 confirmed the role of rhynchospenes as virulence factors in barley disease. …”

    Anti-proliferative effects of <i>Parkia javanica</i> bark and <i>f</i>ruit extract on zebrafish. by Rasik Dhakal (16632279)

    Published 2023
    “…<p>(A) The number of cells represented in brown dots has decreased in embryos treated with fruit extract compared to the control in 1/10<sup>th</sup> of LC<sub>50</sub> concentration (34.6 ppm). …”

    Establishing short-term occupational exposure limits (STELs) for sensory irritants using predictive and <i>in silico</i> respiratory rate depression (RD<sub>50</sub>) models by Anthony J. Russell (17827175)

    Published 2024
    “…A strong correlation between RD<sub>50</sub>s and STELs was identified, with a predictive equation of ln (STEL) (ppm) = 0.86 * ln (RD<sub>50</sub>) (ppm) − 2.42 and an R<sup>2</sup> value of 0.75. …”

    Uncoupling protein-2 is an antioxidant that is up-regulated in the enamel organ of fluoride-treated rats by Maiko Suzuki (8794223)

    Published 2020
    “…Uncoupling protein-2 (<i>Ucp2</i>) was significantly up-regulated by F<sup>−</sup> (∼1.5 & 2.0 fold for the 50 or 100 ppm F<sup>−</sup> treatment groups, respectively). …”

    <b>Wind speed manipulation experimental data from the Community Land Model version 5 (CLM5)</b> by Haohao Wu (18243244)

    Published 2025
    “…Then, experimental simulations were conducted using CLM5 for varying wind speed scenarios for the period of 1983 – 2014, including:</p><p dir="ltr">i) Control run: The simulation was forced by the default air forcing dataset of CLM5 – CRUNCEP version 7 meteorological data (6-hourly data; https://rda.ucar.edu/datasets), except for wind speed, which was replaced by data from the CRU JRA version 2.2 dataset, because the CRUNCEP7 wind speed revealed widespread increasing trend of terrestrial wind speed during 1983 – 2014, inconsistent with observations; in contrast, CRU JRA2.2 wind speed showed overall decreasing trend of terrestrial wind speed during the same period. …”
