    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. …”

    A comprehensive review of hydrogen generation by water splitting using 2D nanomaterials: Photo vs electro-catalysis by Fares Almomani (12585685)

    Published 2023
    “…MXene has been rigorously investigated based on TiO<sub>2</sub> modification (i.e. in-situ derived MXene-TiO<sub>2</sub> and MXene/TiO<sub>2</sub> nanocomposite) as well as Metal-MXene co-catalyst that provides simple electron channelization to improve overall electro and photo-catalytic activity (Cat<sub>A</sub>)toward W<i>sp</i> and increase the hydrogen evolution reaction (HER). …”

    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. …”
