    Complex treatment of oily polluted waters by modified melamine foams: from colloidal emulsions to a free oil removal by Sarah Hailan (17787584)

    Published 2023
    “…The water contact angles (WCA) were 146° ± 2°, 148° ± 4°, 153° ± 2°, and 150° ± 4° for foams modified by the solutions with concentrations of 0.001 M, 0.005 M, 0.01 M, and 0.02 M, respectively. This modification enables the efficient treatment of various oil/water systems, including oil/water colloidal emulsions (99 vol% of the droplets have dimensions below 500 nm), oil-in-water mixtures up to 40 weight % of the oil component, and “free” oil removal as it was demonstrated in this study for the first time. …”

    Photocatalytic water splitting by Khnayzer, Rony S.

    Published 2013
    “…Using this technique, low energy photons supplied by the sun can be converted into light of appropriate energy to trigger electronic transitions in high energy absorbing photoactive materials without any chemical modification of the latter. We have shown, that this technology is capable of upconverting visible sunlight to sensitize wide-bandgap semiconductors such as WO3, subsequently extending the photoaction of these materials to cover a larger portion of the solar spectrum. …”

    Physical and chemical properties of black carbon and organic matter from different combustion and photochemical sources using aerodynamic aerosol classification by Dawei Hu (2186113)

    Published 2021
    “…This suggests that the effect moisture has on the organic chemical profile of wood burning emissions is through changing the durations of the different phases of the burn cycle, not through the chemical modification of the individual phases. In this study, the incandescence signal of a Single Particle Soot Photometer (SP2) was calibrated with three different types of BC particles and compared with that from an Aquadag standard that is commonly used to calibrate SP2 incandescence to a BC mass. …”
