Earlier this year, we ran ANFF 2025 – Future Capabilities Consultation. This was a chance for the fabrication community to get together and talk about the research challenges that we’re seeking to tackle in the next seven to ten years. In February and March 2015, events were held in six cities across Australia. Based on the Australian Academy of Science’s ‘National Nanotechnology Strategy 2012’, we considered four different thematic areas: photonics, nanobio, advanced materials, and nanoelectronics. Key findings from the consultation, which are outlined on the following pages, will contribute to identifying the research infrastructure capability that ANFF needs to offer going forward. 6 ANFF THE HOME OF TOMORROW’S ENTREPRENEURS anff.org.au

Researcher Dr Luke Parkinson at ANFF-SA, in collaboration with Dr Andrew Rose of Southern Cross University, has recently constructed microfluidic devices that can control the conditions under which mineral formation occurs. The devices enable researchers to mix two reagents (in the form of thick streams of liquid), which enter the device through separate channels. The inner walls and channels of the device split the streams into much thinner streams, which then wrap around each other to form a single thick stream. This process – which is known as interdigitising and can be likened to fingers being wrapped around each other – is repeated many times so that the final stream is a near perfect mixture of the original streams of liquid. All of this happens within a few millionths of a second, and observations can be made using various methods, • An early version of the free jet micromixer in operation at the Australian Synchrotron for X-ray such as X-ray scattering. scattering studies of calcium carbonate mineral formation.

This belief has been based on results gleaned from studying extremely thin samples or nanoparticles. Researchers at the University of Queensland in the ANFF-Q node have recently provided new evidence that this common belief is not true for bulk materials, which are used in industrial scale hydrogen storage systems. Their project, led by Dr Kazuhiro Nogita, has shown that in bulk MgH2, dehydriding takes place by a process of nucleation and growth of magnesium grains, inside the bulk hydride particles but not from the surface of the particles. This finding will influence significantly the system operation conditions of hydrogen storage systems. • Schematic hydrogen release mechanisms from a MgH2 grain: (a) multiple ‘nucleation and Using advanced technology including growth’ model for bulk MgH2 grains and (b) ‘shrinking core’ model for thin MgH2 TEM samples. the Differential Scanning Calorimeter Credit: (SCIENTIFIC REPORTS | 5 : 8450 | DOI: 10.1038/srep08450). anff.org.au ANFF THE HOME OF TOMORROW’S ENTREPRENEURS 17
CYBERSECURITY In the modern world, the cyber landscape is just as real as the physical one. Cyber infrastructure is relied upon by government, business, defence, emergency services, and the wider community, making its security of paramount importance. Quantum science is an area where Australia excels on an international stage, with two ARC Centres of Excellence active in the area. Quantum technologies evolving from this science will deliver many capabilities to the cyber world that are beyond the capacity of classical computers. These will be of immense importance for Australia’s cybersecurity future. 18 ANFF THE HOME OF TOMORROW’S ENTREPRENEURS anff.org.au

This largely negates the efficiency improvements researchers have achieved for crystalline cells over the last few decades. Since 2013, the CSIRO Microfluidics team led by Dr Yonggang Zhu has been developing a new thermal management system to address some of the fundamental challenges associated with solar photovoltaic technologies. The project is part of a $4 million SIEF (Science and Industry Endowment Fund) project – ‘High performance solar cell technology with integrated nanoplasmonic thin film and thermal management systems.’ In this project, Swinburne University of Technology and CSIRO researchers are working jointly to overcome the efficiency losses that solar cells suffer when exposed to high temperatures. In tackling this problem, the CSIRO team has developed a novel heatpipe plate system that can be integrated with PV panels. The system utilises unique microscale thermal and fluid behaviors to remove heat with high efficiency. The devices were fabricated and tested in the Micro and Nanomanufacturing Laboratory, an ANFF Victoria facility based at the CSIRO Clayton site. • A prototype heatpipe plate device developed at CSIRO held by Dr Yonggang Zhu. anff.org.au ANFF THE HOME OF TOMORROW’S ENTREPRENEURS 23
