An exploration of supramolecular tape-like assemblies formed by pyridine dicarboxylates
This investigation builds on a previous survey of the solid-state behaviour of pyridinedicarboxylate diesters, an overview of which is presented in Chapter 1. These compounds have been shown to form tape-like assemblies, mediated by a novel triple hydrogen bond motif.<br/>Chapter 2 examines the …

Design, synthesis, and characterisation of transition-metal dicarboxylate anodes for lithium-ion batteries
… this thesis develops the use of transition-metal dicarboxylates as anode materials for Li ion batteries. A holistic approach to this development was taken, exploring the interdependency of the numerous parameters that affect the overall electrochemical performance. Specifically examined were how …

Substrate specificity and functional characterization of sodium/dicarboxylate cotransporters
Transport of dicarboxylates across the plasma membrane is mediated by the Na+/dicarboxylate cotransporters (NaDCs) belonging to the SLC13 gene family. These transporters play important roles in the homeostasis of dicarboxylates. The studies in this dissertation focused on two aspects of the NaDCs: …
