X-Ray Capabilities for Characterisation of
Energy Materials and
Devices
X-rays are high energy , penetrating light with wavelengths around the length of atomic bonds , which gives them unique properties for exploring energy materials . Our experienced team of twelve instrument scientists can assess chemistry , surfaces , mineralogy and high-resolution 3D images of energy materials and devices for research or industry , often under dynamic conditions during operation . |
Competitive Advantage • Largest combined X-ray laboratory in Australia offering an unparalleled range of instrument capabilities and technical expertise – XRD , TF-XRD , SC-XRD , XPS , XRF , micro-XRF , XPS , micro-CT , EXAFS
• Easy access and support for enquiries , problem solving , multi-technique projects , training , and professional administrative services
Impact • Deeper understanding cell performance during charge-discharge cycling by monitoring changes in solid electrolyte mineral phases in operando
• Fine-tuning hydrogen-storage in molecular framework materials
• Optimising surface chemistry of graphite-coated electrodes
• Confirming chemistry and structure of thinfilm multilayer semiconductors ( e . g ., thin-film photovoltaics )
|
Capabilities and Facilities • Mineralogy and molecular structure – X-ray diffraction of bulk solids and thin-films and crystals
• Chemistry – X-ray fluorescence of bulk solids from % to ppm
• Surfaces – X-ray photoelectron spectroscopy for chemistry at the top 5 nm , or nanoscale depth profiling
• 2D Imaging – X-ray fluorescence microscopy down to 20mm under inert gas or vacuum
• 3D Imaging – micro-CT with helical and circular scanning mode with pressure and flow cells for various sample sizes and image processing support
