    Tandem Imaging of Breath Ethanol and Acetaldehyde Based on Multiwavelength Enzymatic Biofluorometry حسب Kenta Iitani (4175995)

    منشور في 2024
    "…Each mesh exhibited selective responses to the target VOCs, with no significant impact on the dynamic range observed in either the single or tandem configurations (EtOH 1–300 ppm, AcH 0.2–5 ppm). The 90% response time was close after time–domain image differential analysis (EtOH = 26 s and AcH = 15 s). …"

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

    منشور في 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. …"

    Effect of Flow Conditions on the Dynamics of Chemical Demulsification in Highly Viscous Emulsion Flow حسب Samuel Vitor Saraiva (17984521)

    منشور في 2025
    "…We evaluated the effects of flow rate (40–120 mL/min), dispersed phase fraction (30–50 vol %), temperature (30–50 °C), and shear promoted by a pump on the dynamics of demulsification model parameters. …"
