Here at the Australian Synchrotron, we strive to achieve high standards in everything we do. And now we have the paperwork to prove it.
In June 2009, the AS was awarded ISO 9001:2008 quality management system certification after a comprehensive external audit of policies, procedures and documentation in every aspect of our operations. The exercise involved staff across all organisational functions, with the User Office in particular coming through with flying colours.
What does this mean? If you’re a user, it means an extra level of confidence that we have everything in place to optimise your scientific experience at the synchrotron all the way from bringing your samples in to taking your data home.
More specifically, the ISO 9001:2008 certification requires us to have specified procedures to cover all key business processes – from operations and equipment maintenance to staff management and record keeping. And from now on we’ll keep checking them to make sure we are working at peak performance.
We believe we are the first synchrotron in the world to achieve international certification for our quality management standards.We’re working hard to keep up our standards – so that you can take them for granted.
AUSTRALIAN SYNCHROTRON DEVELOPMENT PLAN
The key activity of this consultation process is a series of ASDP Workshops around Australia and in New Zealand. The objective is to engage with all stakeholders and the broader scientific community in the process that will lead to the realisation of the ASDP – a roadmap for the future of the Australian Synchrotron over the coming decade.
Each half-day ASDP Workshop will include updates on the current status of the AS as well as ongoing development plans for experimental facilities and supporting infrastructure. We will also be presenting details on the mechanism by which the ASDP will be realised and how the whole community may be involved. Finally but importantly, we propose to ‘open the floor’ in a discussion panel format so that ideas and suggestions can be openly discussed. We would encourage all of you not to miss this opportunity to be part of the future of synchrotron science in Australia.
So far this month workshops have been held in Canberra, Brisbane and Sydney.

We welcome all of you to come along to the ASDP Workshops and have your say!

Greg Metha from the University of Adelaide is using the far-infrared and high-resolution beamline to study metal-carbide nanoparticles with some exciting potential applications.
Many modern industrial processes rely on catalysts that make chemical reactions happen or run faster. Platinum-group metals are the workhorses of industrial catalysis, but their high cost and limited efficiency has prompted a search for alternatives.
Metal-carbide nanoparticles made from carbon bonded to metals such as titanium, niobium or chromium have chemically-similar surface properties to platinum-group metals – and potentially superior selectivity and efficiency. They are also cheaper to produce, but their small size makes them difficult to study.
Greg Metha’s team has developed a laser-based method for preparing titanium carbide and other metal-carbide nanoparticles in aqueous solutions. The particles are small (5-10 nanometres) and uniform in size, but their chemical structure is unknown. After laboratory techniques failed to identify the chemical bonds present in the nanoparticles, Greg turned to the Australian Synchrotron.
Using the far-infrared and high-resolution beamline, Greg and German exchange student Birte Riechers collected data showing the presence of metal-carbon bonds, as expected. A more surprising find was carbon-hydrogen bonds, suggesting the nanoparticles may be able to catalyse the decomposition of water.
Greg’s next step will be to test metal-carbide nanoparticles prepared in deuterated water to find out whether the carbon-hydrogen bonds are formed during production of the nanoparticles or from subsequent reactions with the air.
They’re an integral part of everyday life, but many people have never heard of them.
Perovskite-type minerals have numerous commercial applications such as medical sensors for measuring blood pressure, microphones, mobile phones, hydrogen fuel cells, and sonar transducers for tracking fish and submarines. Japan alone fabricates an estimated four billion devices containing perovskites each year.
The key to the widespread usage of this class of minerals is the enormous structural and compositional flexibility of the perovskite structure. Perovskite-type oxides can be fine-tuned to take advantage of an appropriate structural, electronic, or magnetic ‘instability’, which confers a particular functional capability such as that required for switches in computer memories.
Brendan Kennedy and collaborators from the University of Sydney are using powder diffraction at the Australian Synchrotron to establish the precise structures of specific perovskite-type oxides and their responses to temperature changes. The work has important fundamental and practical implications.
A further reason to study perovskites is that they are important components of the earth’s lower mantle, which extends downwards from about 450 kilometres below our feet. Understanding their stability under lower mantle conditions is crucial for interpreting the physical and chemical properties of the whole Earth.
Brendan and his ANSTO research collaborators recently extended their perovskite work to technetium oxides. Powder diffraction studies at the AS have revealed some unexpected structural and magnetic transitions, and further analysis is underway.
“Technetium is the most widely used medical isotope but it’s radioactive so we couldn’t do this work outside Australia,” Brendan told Lightspeed. “Being able to do powder diffraction at the Australian Synchrotron also means we have more flexibility to measure data under different conditions.”
In July 2009, Qinfen Gu from the Australian Synchrotron’s powder diffraction team attended the Advanced Crystallography at High Pressure meeting in Harbin, China organised by the International Union of Crystallography (IUCr) Commission on High Pressure. Qinfen presented a talk entitled ‘High pressure effects on pyrochlore-type superconductors’.
The trip was part of the powder diffraction team’s efforts to maintain their knowledge of the latest developments in response to increasing user interest in high-pressure sample environments for powder diffraction.
High-pressure science and technology has made great progress in recent years and is becoming more widely applicable to research areas extending beyond earth and planetary science to physics, chemistry, materials science and the biosciences.
