A new printing technology can now simultaneously print living stem cells and the environment they need to survive and become the right cell type. The first application is a cartilage repair kit.
“Our current 3D printers can integrate living and non-living materials in specific arrangements at a range of scales, from micrometres to millimetres,” says Professor Gordon Wallace, Director of the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong.
“And we’re developing new approaches that will enable 3D printing of nano-dimensional features.”
A stable and compact nuclear waste technology is moving from research level to industrial-scale at the Australian Nuclear Science and Technology Organisation (ANSTO).
The planned full-scale nuclear waste treatment plant incorporates ANSTO’s Synroc innovation that locks away radioactive waste products by mimicking natural geology.
“A key part of the Synroc process is Hot Isostatic Pressing, which applies heat and pressure to minimise the disposal volume and transform liquid radioactive waste into a chemically durable material suitable for long term storage,” says Gerry Triani, Technical Director at ANSTO Synroc.
Lithium batteries have transformed power storage—from smartphones to electric cars and submarines. But like every battery their chemical composition changes through every charge cycle.
Lithium ions sitting in layers of graphite move between electrodes and change the oxidation state of, magnesium oxide, for example. The chemical rearrangements cause the graphite and oxide layers to physically expand and contract by up to 15 per cent at every cycle, cracking and detaching from the electrodes.
Sending quantum messages over long distances will be challenging. The signal will have to be amplified every few hundred kilometres, but conventional optical amplification would destroy the quantum message.
In a quantum information system, if you measure the light, you will destroy the information encoded on it. You need to store the light itself.
“We have to catch and store the light, but we’re not allowed to look at it to see what information it contains. If the system is working, the light will be exactly the same when we let it out again. We do this by absorbing the light into a cloud of atoms,” says Dr Ben Buchler.
Polymers are being used for non-stick coatings, anti-fouling technology, precision drug delivery, medical diagnosis, imaging, and many other applications.
Associate Professor Cyrille Boyer’s ideas are built on the revolutionary RAFT techniques (a technique to precisely control how small molecules are linked together to form large polymer chains) for which Professor David Solomon and Dr Ezio Rizzardo received the 2011 Prime Minister’s Prize for Science. His latest technology uses light and chlorophyll to catalyse the production of polymers.
The development of a two-quantum bit (qubit) logic gate in silicon heralds the possibility of moving quantum computers from experimental lab to large-scale manufacture much faster than other global research efforts.
Scientia Professor Andrew Dzurak and his team have created a two-qubit gate – a critical component, which allows qubits to talk to each other and will form the basis for a quantum computer chip.
It’s an advance that the UK’s premier physics magazine, Physics World, declared one of the top 10 breakthroughs of 2015.
Traditional buildings in Indonesia make use of ‘passive’ cooling techniques. Being well ventilated, raised off the ground, and with shady verandas, their design allows them to stay cool in a tropical climate without air conditioning. The classic timber ‘Queenslander’ house also follows a similar design.
Now architects and engineers from both countries are getting together to compare notes on such designs and materials.
Just under half the children in Australia with a mental health issue aren’t receiving the appropriate treatment, and one third of their parents say the main impediment is a lack of access to treatment options.
“We’ve got all these great programs that we know work, but kids in rural Australia have just not been getting access to them,” says Dr Lauren McLellan, a clinical psychologist and Research Fellow at the Centre for Emotional Health.
Patented University of Wollongong technology is being used to create foldable batteries and textiles that are super strong, light, can repel water, and act as sensors.
Australian company Imagine Intelligent Materials has a commercial licensing deal to use the graphene manufacturing technology, developed at the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong.
Miniscule plastic particles with the potential to cause havoc in our waterways and oceans have been found in the stomachs of over a quarter of fish sampled in Sydney Harbour.
Named microplastics, the tiny plastic fragments, beads and fibres are sometimes made directly as beads, and sometimes created by the break-down of plastics used in clothing, packaging, fishing gear, nappies and wipes.
