A Multidisciplinary Research Platform for Nuclear Spins far from Equilibrium

Lead Research Organisation: University of Southampton
Department Name: School of Chemistry

Abstract

Nuclear Magnetic Resonance (NMR) is a technique which uses the fact that the nuclei of many atoms act as tiny radiotransmitters, emitting radio signals at precisely-defined frequencies, which can be detected by a carefully-tuned detector. In an NMR experiment, the nuclei are first magnetised by placing a sample in a strong magnetic field for some time. A sequence of radiofrequency pulses is then applied to the sample, which subsequently emits radiowaves which are detected in the radio receiver. The pattern of emitted waves provides information on the chemical composition and spatial distribution of the sample.

Magnetic nuclei may be viewed as small bar magnets, which may point in any direction in space. In normal circumstances the directions in which the nuclear magnets point are almost uniformly distributed, meaning that all directions are almost equally likely. As a result the net nuclear magnetism almost completely cancels out. However, when a strong magnetic field is applied, there is a very small change in this distribution, so that slightly more nuclei point along the applied field, than opposite to it. A very small net magnetism is developed along the applied field, and this is used to generate NMR and MRI signals.

It is possible to generate materials with strongly perturbed nuclear spin distributions. There are two different types of non-equilibrium nuclear spin states.

In the first type, the nuclei are strongly lined up in one direction, to a degree which is much greater than that which is available without intervention. Such materials are said to be hyperpolarized. Materials in hyperpolarized states can generate NMR signals which are 100000 stronger than normal. This phenomenon has already been used in clinical trials for the detection of cancer in human patients.

In the second type of non-equilibrium spin state, neighbouring nuclei in the same molecule are strongly aligned with other, as opposed to being aligned along an external direction. In sufficiently symmetrical molecules, this leads to the phenomenon of spin isomerism, in which compounds with different nuclear spin configurations behave as separate physical substances, which can be stable for a long time. The seminal case is hydrogen gas (H2) where the spin isomers are called ortho and parahydrogen. These spin isomers were predicted to exist by Heisenberg (for which he was awarded a Nobel prize) and their existence is one of the triumphs of quantum mechanics. Recently our group showed that ordinary water may also exhibit ortho and para spin isomers, providing the water molecules are trapped inside carbon cages (fullerenes) so that they are free to rotate at low temperature. We also showed that the type of water spin isomer has an influence on the electrical properties of the material.

In this Platform Grant we will further develop the sciences of hyperpolarization and spin isomerism and explore how they relate to each other. In some circumstances, spin isomerism may lead to hyperpolarization, and vice versa. By conducting this research we will learn a great deal about the behaviour of magnetic nuclei in symmetrical molecules, and develop new methods for enhancing NMR signals by enormous factors, which will have an impact on a wide range of sciences, including clinical medicine and the detection and characterisation of cancer.

The new science of materials in nuclear spin states which are far from equilibrium also offers commercial opportunities in the form of novel MRI (magnetic resonance imaging) technology, and hyperpolarized imaging agents.

During the project we will give our research team the opportunity to work flexibly and interactively across several interlocking disciplines. An innovation fund with an internal bidding process will be instituted to allow the participating researchers to explore their own ideas and to visit other laboratories.

Planned Impact

1. Academic impact

1.1 New knowledge and scientific advancement.
The research in this proposal is fundamental in nature. How are materials generated with highly non-equilibrium nuclear spin states? How may such states be maintained for significant times? What materials phenomena are associated with highly non-equilibrium nuclear spin states? How can such phenomena be exploited in NMR and other fields such as medicine, biochemistry, materials science and superconductivity?

The proposal is highly interdisciplinary involving organic and inorganic chemistry, quantum physics, materials science, biochemistry, cryogenics and imaging.

1.2 Worldwide scientific advancement
The proposal is part of an ongoing direct collaboration with project partners from Estonia, Denmark and France. In addition the participating groups have close collaborations with research groups in Germany, Greece, Sweden, Japan, India, Australia and USA.

1.3 Development of new methodologies, equipment, techniques, cross-disciplinary approaches.
The project uses multiple new methodologies, equipment and techniques. The project is highly cross-disciplinary, involving chemistry, quantum physics, imaging, biochemistry, and reaches out into clinical medicine.

1.4 Delivering and training researchers.
The named researchers will be given the opportunity to lead their project packages and to train as a research leader of the future. We will mentor these young researchers into future academic leadership roles.

2. Economic and Societal Impact

2.1 Societal benefits. The research described here is directed towards the development of enhanced imaging modalities, of potentially great benefit to the diagnosis and treatment of a wide range of diseases, especially early detection of cancer and better characterisation of its response to treatment. These new modalities can therefore considerably increase the efficacy of treatments while reducing cost. In addition some projects under this platform will develop techniques which have the potential for improving energy materials.

Science is a cultural activity - especially basic science. Basic research of this nature is therefore culturally enriching.

2.2 Economic benefits. Magnet technology is a strength of UK engineering so enhancements in NMR and MRI are of long-term economic benefit to the UK. In particular Oxford Instruments has invested heavily in HYPERSENSE technology so that advances in this technology are very important for that key company. Cryogenic and Thomas Keating are other UK companies with a heavy investment in advanced magnetic resonance technology. GE also has facilities located in the UK. The technologies developed in this project may underpin new startup companies: for example new devices for producing hyperpolarized materials, or compounds which may be prepared and transported in a hyperpolarized state, and better and more transportable MRI systems.

Improved efficiency in the treatment of diseases such as stroke and cancer will reduce the cost burden on health services.

The training of researchers in advanced NMR and MRI techniques and their associated theory will equip UK industry to compete better in these areas in the future, bringing further economic benefits. Even if researchers on this grant end up in different fields, their experience of the highly interdisciplinary environment in this project will equip them well to conduct and lead interdisciplinary and flexible activities in the future.
