Fused-Ring Pyrazine Derivatives for n-Type Field-Effect Transistors
, 2016 Three new fused-ring pyrazine derivatives end-functionalized with trifluoromethylphenyl groups have been synthesized. The effect of a fused-ring pyrazine core on the thermal, electronic, optical, thin film morphology, and organic field-effect transistor (

Dy2 Schiff Base Single Molecule Magnet Forming a Halogen Bonding Network: Experiment and Theory
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.A major challenge to improve SMMs is control over phonon‐based relaxation mechanisms, such as the Raman process. We approach this challenge through the incorporation of intermolecular interactions, which can restrict acoustic phonon modes. For this, we engineer the crystal lattice of a Dy2 SMM using halogen bonding and investigate its properties using ...

Targeting protein–protein interactions with reversible covalent modalities: Non‐cysteine chemistries
British Journal of Pharmacology, EarlyView.Abstract Protein–protein interactions (PPIs) are central to diverse cellular functions, and represent a rapidly expanding class of therapeutic targets. Advancements in covalent drug design have enabled small‐molecule drugs to overcome challenges associated with engaging these targets, such as limited durations of action and difficult‐to‐drug (expansive,

, 2022 Curiosity and sustainable development go hand in hand to help with the major problems of our time. This thesis shows how curiosity driven research can result in new insights. The thesis describes the development new building blocks from biomass, which have never been used in materials before, and their subsequent use in plastics.

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
