Injection, transport and detection of spin currents in organic semiconductors
… spin currents in organic semiconductors based on dynamic nuclear polarisation and organic magnetoresistance. It uses the spin-Hall effect as the source of spin currents and is therefore free from the numerous spurious effects that accompany the spin pumping method. We have conducted initial …

NMR Studies of Interfacial Reactions in Lithium-Ion Batteries
… In this work, solution- and solid-state nuclear magnetic resonance (NMR) methodologies are developed for studying the electrode-electrolyte reactions. The decomposition reactions of the electrolyte solution at positive electrodes, layered transition metal oxides (LiMO2, M = Ni, Mn, Co or …

Preserving hyperpolarised nuclear spin order to study cancer metabolism
… and spatial resolution. In combination with the dynamic nuclear polarisation (DNP) technique, high signal-to-noise is obtained, resulting in a powerful tool for in vivo 13C metabolic imaging. However, detection of hyperpolarised substrates is limited to a few seconds due to the exponential decay …

Mathematical approaches for the clinical translation of hyperpolarised 13C imaging in oncology
Dissolution dynamic nuclear polarisation is an emerging clinical technique which enables the metabolism of hyperpolarised 13C-labelled molecules to be dynamically and non- invasively imaged in tissue. The first molecule to gain clinical approval is [1-13C]pyruvate, the conversion of which to …

Investigation of cell interfaces and strained tissues with solid-state NMR
Solid-state nuclear magnetic resonance (ssNMR) is an immensely powerful tool for structural biology, which can provide insights into the composition, structure, dynamics of biological components. In combination with <sup>13</sup>C amino acid enrichment of cell fibroblasts *in vitro*, ssNMR has been …

Solid-State NMR of Metallic and Paramagnetic Systems
Solid-state nuclear magnetic resonance (ssNMR) is a powerful element-specific technique to study local atomic environments in many different classes of materials; however, ssNMRbased methodologies have primarily focussed on diamagnetic systems without any unpaired electrons. In paramagnetic or …
