    From 2D to 1D Electronic Dimensionality in Halide Perovskites with Stepped and Flat Layers Using Propylammonium as a Spacer by Justin M. Hoffman (6890504)

    Published 2019
    “…Two-dimensional (2D) hybrid halide perovskites are promising in optoelectronic applications, particularly solar cells and light-emitting devices (LEDs), and for their increased stability as compared to 3D perovskites. Here, we report a new series of structures using propylammonium (PA<sup>+</sup>), which results in a series of Ruddlesden–Popper (RP) structures with the formula (PA)<sub>2</sub>(MA)<sub><i>n</i>−1</sub>Pb<sub><i>n</i></sub>I<sub>3<i>n</i>+1</sub> (<i>n</i> = 3, 4) and a new homologous series of “step-like” (SL) structures where the PbI<sub>6</sub> octahedra connect in a corner- and face-sharing motif with the general formula (PA)<sub>2<i>m</i>+4</sub>(MA)<sub><i>m</i>−2</sub>Pb<sub>2<i>m</i>+1</sub>I<sub>7<i>m</i>+4</sub> (<i>m</i> = 2, 3, 4). …”

    Identification, Synthesis, and Biological Evaluations of Potent Inhibitors Targeting Type I Protein Arginine Methyltransferases by Xiao Li (107004)

    Published 2022
    “…In this study, we first identified several hit compounds against CARM1 by structure-based virtual screening (IC<sub>50</sub> = 35.51 ± 6.68 to 68.70 ± 8.12 μM) and then carried out chemical structural optimizations, leading to six compounds with significantly improved activities targeting CARM1 (IC<sub>50</sub> = 18 ± 2 to 107 ± 6 nM). …”
