Deaminative vinylation and arylation cross-coupling reactions
, 2023 Watson, Mary P.This thesis focuses on nickel-catalyzed vinylation and arylation cross-coupling reactions via C-N bond activation. Chapter 1 describes a vinylation method that was inspired by an analogous alkylation.

Access and Modulation of Substituted Pyrrolo[3,4-c]pyrazole-4,6-(2H,5H)-diones
Molecules, 2023 The first access to polyfunctionnalized pyrrolo[3,4-c]pyrazole-4,6-(2H,5H)-dione derivatives is reported. The series were generated from diethyl acetylenedicarboxylate and arylhydrazines, which afforded the key intermediates bearing two functional ...

Synthesis of chiral germanium center enabled by poly-deborylative alkylation and desymmetrization
Nature CommunicationsChiral germanium centers are historically undervalued due to their extremely limited synthetic accessibility. Although germanium shares similar chemical properties with silicon, synthesizing chiral germanium centers proves significantly more challenging.

Non-linear MPC for winding loss optimised torque control of anisotropic PMSM
The Journal of Engineering, 2019 For a non-linear anisotropic permanent magnet synchronous machine (PMSM), a prediction model for model predictive control (MPC) considering effects like cross-coupling and saturation is developed in a straight forward procedure.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
