    Pulse Ultrasound-Based Response Enhancement of a MOX Gas Sensor by Yumin Yang (5737235)

    Published 2024
    “…Comparing the steady responses of five target gases under the pulse and continuous ultrasound, respectively, it is found that the pulse ultrasound causes a better catalysis effect, and response enhancement (RE) by the pulse ultrasound with an optimal pulse width depends on the ultrasonic strength as well as the species and concentration of the target gas. For 2 ppm methanol, the RE by the pulse ultrasound is 50%, relative to the continuous ultrasound, when the pulse width, duty ratio, and working frequency are 0.4 ms, 50%, and 110.1 kHz, respectively. …”

    Effects of Membrane Degradation due to Chlorine Exposure on the Removal of Neutral Organic Compounds by Reverse Osmosis for Potable Reuse by Carson Odell Lee (17810305)

    Published 2024
    “…Compounds that had an initial rejection between 50 and 95% had a rapid decrease in rejection during the first 230 ppm-h of chlorine exposure, whereas compounds with a new membrane rejection of >95% saw little change in rejection until chlorine exposure exceeded 2640 ppm-h. …”
