Development of advanced metal oxide materials for next generation nonvolatile memory devices. The purpose of the project is to explore a new memory technology, resistive random-access memory, that can be made smaller than those of today, as well as preferably being faster, power saving and nonvolatile. The project is expected to bring resistive random-access memory materials a step closer to nonvolatile memory devices application.

The use of thin hard abrasion-resistant coatings is an important method for significantly improving the operational lifetime of components in a wide range of mechanical, biomedical and sensory applications. The optimal design of these coatings is however severely restricted by a lack of detailed knowledge of their material deformation mechanisms. The proposed project will use novel nano-indentation and electron microscope techniques to create a basis for mechanism-based deformation models. These models will then be used to develop new coating architectures with improved operational lifetimes as well as predicting coating lifetimes and developing simple tools for coating assessment.Read moreRead less

The work has the potential for very substantial benefit to Australia. Novel stress corrosion cracking resistant tempers with improved strength have the potential for widespread application in the aircraft industry. Since the patent for the interrupted ageing process is held by CSIRO there is the potential for substantial economic benefit to Australia from the licensing of the novel tempers world-wide. Additionally, it would be possible to develop the novel tempers in-situ on existing aircraft structures to improve their performance. This would be of particular benefit to the Royal Australian Airforce with its fleet of ageing aircraft.Read moreRead less
