    Synthesis of polymers 5 and 6. by Ghadeer Mubarak (21567569)

    Published 2025
    “…The results showed that AMCs act as efficient corrosion inhibitors, with over 90% inhibition efficiency ( ) at 20 ppm concentration. The electrochemical investigation results indicated that the AMCs with hydrophilic and hydrophobic ratios of 100 (<b>5</b>), 90:10 (<b>6a</b>), and 80:20 (<b>6b</b>) manifest of 87.74%, 92.12%, and 93.53%, respectively. …”

    Evaluating the Potential of Ozone Microbubbles for Inactivation of Tulane Virus, a Human Norovirus Surrogate by Bozhong Guan (18598178)

    Published 2024
    “…After 2, 10, and 20 min postgeneration, the ozone concentration of microbubbles naturally decreased from 4 ppm to 3.2 ± 0.2, 2.26 ± 0.19, and 1.49 ± 0.23 ppm and resulted in 1.43 ± 0.44, 0.88 ± 0.5, and 0.68 ± 0.53 log<sub>10</sub> viral reductions, respectively, while the ozone concentration of aqueous ozone decreased from 4 ppm to 2.52 ± 0.07, 0.43 ± 0.05, and 0.09 ± 0.01 ppm and produced 0.8 ± 0.28, 0.29 ± 0.41, and 0.16 ± 0.21 log<sub>10</sub> reductions against Tulane virus, respectively (<i>p</i> = 0.0526), suggesting that structuring of ozone in the bubbles over the applied treatment conditions did not have a significant effect, though future study with continuous generation of ozone microbubbles is needed.…”
