Triple resonant electromagnetic structures for polarization transfer in DNP

Mohammed Albannay

Research focus
Nuclear Magnetic Resonance spectroscopy (NMR) and Magnetic Resonance Imaging (MRI) have allowed for advancements in both contemporary science and clinical applications. Despite their versatility and non-invasiveness, NMR and MRI face sensitivity limits due to the weak degree of alignment that the magnetic coupling imparts on the observed nuclear spins. Consequently, hyperpolarisation methods such as Dynamic Nuclear Polarization (DNP) are employed to enhance spin alignment in samples and by extension the sensitivity of an NMR or MRI experiments by several orders of magnitude.

In this project, DNP will be studied as a function of field and temperature conditions. The polarization of the various nuclei (e.g. 1H and 13C) within samples will be studied to explore more efficient polarization schemes.

Project challenges include the realisation of electromagnetic structures with efficient microwave delivery and the development of a two channel spectrometer for solid state NMR, subsequently enabling the implementation of complex schemes e.g. cross polarization.
