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

    منشور في 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> حسب Reynaldi Darma (20713741)

    منشور في 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. …"
