Summary
Advanced X-ray diffraction facility for high energy and extreme conditions. X-ray powder diffraction is a powerful technique for determining the structure of matter at the atomic scale. This project will establish a new Australian capability for X-ray powder diffraction under extreme conditions that emulate real harsh service environments for advanced functional materials.
Enhanced electro-active properties in polycrystalline ceramics: a multi-length-scale approach. Electro-active materials are used in a wide range of devices including ultrasound imaging equipment and nano-positioning systems. This project will determine the most fundamental mechanisms at work in these materials allowing for the optimisation of high-performance and environmentally friendly electro-active devices for future industries.

Summary
Fatigue degradation in lead-free piezoelectric ceramics: the key factor for successful industrial implementation. Many everyday devices, that is mobile phones, operate with lead-based ceramics, which can be hazardous; although there are promising lead-free materials, these show complex electric behaviour which can lead to structural damage and device failure. This project will define the degradation mechanisms so that reliable non-toxic ceramics can be designed.

Legislation against the use of lead initiated a search for lead-free piezoelectric ceramics. This project aims to derive guidelines for the development and implementation of this new class of materials. This project will utilise an analysis technique that allows elucidation of the origin of the high strain in piezoelectric materials. A separate analysis of the three known strain mechanisms in materials with coexisting phases will innovatively correlate theory and macroscopic observation with processes on the atomic scale. The quantification of the contribution of each mechanism will lead to new insights into the enhancement of sustainable functional materials.Read moreRead less
Probing anti-ferroelectric to ferroelectric structural phase transitions: towards high power energy transformation devices. Materials which can be rapidly switched from anti-ferroelectric to ferroelectric states exhibit a wide range of exploitable properties. This project will identify the factors enabling such materials to respond to applied electric fields and mechanical stresses and use them to enhance the ability of industry to develop new advanced materials.
