    High-Temperature Resistance, Lightweight, and Thermally Insulating Silica Aerogel via Doping Hollow Silica Nanoparticles by Mingyang Yang (1405321)

    Published 2025
    “…Traditional solutions to this issue, such as doping with opacifiers or fibers, often increase thermal conductivity and density. To increase the thermal stability of standard aerogels comprising small full-density SiO<sub>2</sub> nanoparticles (SFPs) (typically 2–15 nm in diameter), SiO<sub>2</sub> aerogels were doped with large hollow SiO<sub>2</sub> nanoparticles (LHPs) with diameters of 100–250 nm. …”

    Tuning UV Absorption in Imine-Linked Covalent Organic Frameworks via Methylation by Ellen Dautzenberg (14169199)

    Published 2022
    “…By comparing the properties of all COFs, the following trends were found: (1) upon methylation of the aldehyde nodes, COFs show increased Brunauer–Emmett–Teller surface areas, reduced pore collapse, blue-shifted absorbance spectra, and ∼0.2 eV increases in their optical band gaps. (2) COFs with dimethylated amine linkers show a lower porosity. (3) In tetramethylated amine linkers, the COF porosity even further decreases, the absorbance spectra are clearly red-shifted, and smaller optical band gaps are obtained. …”
