    Cyclopropane as an Unsaturation “Effect Isostere”: Lowering the Melting Points in Lipid-like Ionic Liquids by Richard A. O’Brien (1538818)

    Published 2023
    “…While cyclopropanation of the lipid-like ionic liquids provides more resistance to aerobic degradation than their olefin analogs, the impact on the melting point decrease is not as pronounced. Our results demonstrate that incorporating one or more cyclopropyl moieties in long aliphatic chains of imidazolium-based ionic liquids is highly effective in lowering the melting points of such materials relative to their counterparts bearing linear, saturated, or thioether side chains. …”

    Parrotfish Teeth: Stiff Biominerals Whose Microstructure Makes Them Tough and Abrasion-Resistant To Bite Stony Corals by Matthew A. Marcus (115744)

    Published 2017
    “…Its enameloid is a fluorapatite (Ca<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>F) biomineral with outstanding mechanical characteristics: the mean elastic modulus is 124 GPa, and the mean hardness near the biting surface is 7.3 GPa, making this one of the stiffest and hardest biominerals measured; the mean indentation yield strength is above 6 GPa, and the mean fracture toughness is ∼2.5 MPa·m<sup>1/2</sup>, relatively high for a highly mineralized material. …”

    Scattering from Polydisperse Melts by Marshall Fixman (2703628)

    Published 2004
    “…The systems chosen for illustrative calculations are quasi-binary melts of deuterated and protonated polyethylene and polystyrene, both of which have been reported to exhibit anomalous composition dependence of neutron scattering. Quite large deviations from the Flory−Huggins picture of random spatial mixing of chains are found and the deviations decrease rather slowly with increasing molecular weights. …”
