Funding Amount

Summary
The ENVIS-ion trial will examine whether Aspirin is effective in delaying the onset of worsening of thinking and memory abilities in healthy older adults. Magnetic resonance imaging (MRI) of brain structure will detect markers of early worsening of thinking and memory abilities. Blood vessels in the back of the eye (retina) share many features with vessels in the brain. We will compare whether aspirin lessens changes over time of features shown with brain MRI and retinal photography.

Summary
Previous research supports the notion that physical activity plays a role in maintaining brain health and preventing Alzheimer’s disease. Nevertheless, the type of activity (i.e. intensity of physical activity) that is of greatest benefit to the brain is yet to be established. This project aims to identify the most beneficial exercise intensity, in terms of brain health, measured utilising brain imaging technology.

This project enables collaborations between Australian and European groups in an important and expanding area at the forefront of technology, and facilitates access to state of the art resources in laboratories in Austria and Spain. It carries across knowledge in synchrotron techniques just at the right time, just before the Australian synchrotron goes on line in 2008, allowing time to deepen expertise and to obtain specific knowledge. It will help establish a new effort at the University of Western Australia concentrated on developing advanced materials for technology. We will make important contributions to an internationally important area and offer high quality interdisciplinary research training in magnetic nanomaterials science.Read moreRead less
Fast and slow dynamics at coupled magnetic interfaces: Theory and Experiment. Immediate needs for advances in materials for spin electronics and information technology require a deeper physical understanding of new materials in which interfaces and nanometre dimensions determine properties. Interfacial exchange coupling between magnetic layers is a key issue in the formation of many multilayer structures, and several important issues remain unresolved. This is a proposal for a joint theoretical ....Fast and slow dynamics at coupled magnetic interfaces: Theory and Experiment. Immediate needs for advances in materials for spin electronics and information technology require a deeper physical understanding of new materials in which interfaces and nanometre dimensions determine properties. Interfacial exchange coupling between magnetic layers is a key issue in the formation of many multilayer structures, and several important issues remain unresolved. This is a proposal for a joint theoretical and experimental study of technologically important magnetic interfaces by groups at Universities of Florence, Perugia, Leeds and Western Australia.Read moreRead less

The aim of this project is to provide first measures of certain key energies and rates associated with magnetic processes. Through a combination of theoretical modelling and experiment design, a new experimental technique will be developed into a powerful analysis tool. This work will establish the technique in Australia and create new opportunities for future study.

Films containing layers of different types of magnetic materials - in particular, ferromagnetic and antiferromagnetic - have properties which are being exploited in magneto-electronic devices used in recording and manipulation of computer data. These properties are determined by new types of magnetisation processes in the interface between layers. In this project investigations of the magnetic behaviour of interfaces will be made to provide information of value in the design and optimisation of new and existing devices. The procedures to be developed in this project will be applicable to the understanding of the behaviour of a new range of atomically engineered magnetic structures.Read moreRead less

A well known example is the giant magnetoresistance, a phenomena discovered over fifteen years ago that now plays a key role in current high density magnetic disc drives. Future developments will involve spin dependent transport through structures wherein quantum interference effects will be important. Two basic problems facing the construction of a complete theory of transport in such ?mesoscopic? conductors will be solved in this project. The results will provide important insights into the dynamics of spin transport through structures such as magnetic nano-wires.Read moreRead less

Our approach is based on the spin-resolved two-electron coincidence spectroscopy that is inherently suited for studying electronic correlations. Systematic investigations of spin-dependent interactions in atoms, molecules and ultrathin films will increase understanding of magnetic (spin) properties of artificially structured materials with reduced dimensionality for the benefit of nanotechnology. This understanding will be used to design and control, at the quantum mechanical level, the building blocks of spin-electronic devices.Read moreRead less

Conventional electronics is based on coupling the charge of the electrons with external electric fields and light. Recent work on spintronics is directed toward the use of both the spin (angular momentum) and the charge degrees of freedom of the electron. We currently lead the world in the development of spin-resolved coincidence measurements, which make it possible to determine previously inaccessible nanoscale magnetic properties, central to 'spintronic structure engineering'.
