研究领域

My research interests primarily centre on the fundamental nature of molecular and molecule-based materials. Of particular interest are materials displaying novel magnetic interactions, nano-materials and the interactions between molecules in the solid state.

These ideas can be summarised as:

The study of novel molecular and molecule-based magnetic materials demonstrates a wealth of phenomena, ranging from low dimensionality (1D chains and 2D sheets), through to those systems which show no tendency to coalesce into a long range magnetic as a result of frustration - so-called spin liquids and spin ice.

Isolated clusters of several magnetic ions have been found to behave as nano-magnets, characterised as having a single, large magnetic moment per cluster. When these isolated moments have an inherent spin-relaxation anisotropy, they can behave as an ensemble of isolated, identical magnetic particles.

Research into such materials has potential applications in high density magnetic storage media, magnetic films and sensing devices.

The manner in which individual molecules align and condense in the crystalline state is a result of the intermolecular forces that act upon molecules. Long range ordering occurs as a direct result of the translational self-similarity in these forces. Due to the non-spherical nature of most molecules, the final crystalline structure is therefore a balance between the Gibbs free energies of competing potential stacking arrangements.

Supramolecular chemistry is a general term used to cover those studies that attempt to perturb these competing effects to induce one particular ordering motif (or geometry) over another. We aim to study these often very complex interactions first in simple model systems, before building in complexity and moving toward systems displaying apparent emergent behaviour.

Another area in which intermolecular interactions are dominant is nano-science which aims to deliver materials intimately structured on the nano-scale - thousands of times smaller than the width of a human hair. We synthesise and study materials as diverse as single sheets only one atom thick - e.g. graphene - and highly fluorescent nanoparticles such as quantum dots. These materials sit at the interface between the chemistry of individual molecules and the collective physical properties of bulk materials; thechnologically they represent the ultimate in miniturisation.

Research in the Stride Group makes heavy use of neutron scattering techniques and I retain an interest is the development of new neutron instrumentation and methods. These are exciting times for the international neutron scattering community, with new facilities coming online over the next few years. This effort is not lost on Australia; the new national neutron facility at the Bragg Institute, provides doorstep access to world class instrumentation for Australian researchers in fields as diverse as physics, chemistry and materials science, through to the geo-sciences and biology.
