A breakthrough in the electroactive polymers used to make electrically controlled micro “artificial muscles” could be important for future drug delivery in the body, as well as a having a host of other applications.

The new research, conducted at the Australian National Fabrication Facility’s (ANFF) materials node at the University of Wollongong (UOW) in NSW has produced materials which, unlike earlier versions, do not need to be immersed in an electrolyte solution. They are self-sufficient and can even work in air. Continue reading Micro muscles bend to the task→
Miniaturised sensors are nothing new, but ones made from a combination of silicon carbide (SiC) and the single-layer lattice of carbon atoms known as graphene certainly are. These new sensors are being designed to operate under the harshest of conditions.

Research, led by the Australian National Fabrication Facility’s (ANFF) Queensland node at Griffith University, promises a new generation of tiny microelectromechanical system (MEMS) sensors that are sensitive to very low forces, can work at high frequencies and in extreme conditions—above 1,000°C or under an acceleration of several times g—and are resistant to chemical attack.

The first microscopes gave humans the ability peer deep into the microscopic world, allowing us to see cells and microbes in unprecedented detail. Using the latest electron microscopes we are now able to see detail down to single atoms.

In fact, materials scientists can detect impurities in their latest compounds, atom by atom, using powerful electron microscopes aided by sophisticated modelling of what happens when the electron beam hits the material.
Dr Adrian D’Alfonso and a team of theoretical physicists at the University of Melbourne have developed these models and they are already helping groups around the world look at and understand nanomaterials in a way they haven’t been able to before.
China has a large community of astronomers awaiting the construction of new telescopes to study pulsars.
When CSIRO pulsar researcher Dr George Hobbs described the high-quality data stored in the Parkes Observatory Pulsar Data Archive—which is openly available—it led to Australian pulsar data being the basis of collaboration between Chinese and Australian pulsar researchers. And they have already published several papers on what they have discovered. The archive is also serving as a major resource in an international search for gravitational waves.
Melbourne shared in the announcement of the discovery of a Higgs boson-like particle in 2012, and the city is expected to reap millions of dollars in economic benefits brought by the conference at which this discovery was announced.

The announcement that a suspect matching the elusive subatomic particle’s description had been found came at the 36th International Conference on High Energy Physics, held at the Melbourne Convention Centre in July, in a joint announcement with CERN in Switzerland.

In 2012, scientists celebrated at the announcement of the discovery of a Higgs boson-like particle, a subatomic particle that completes our model of how the Universe works.

The announcement was made simultaneously at CERN in Geneva, and to hundreds of physicists gathered in Melbourne for the International Conference on High Energy Physics.
“As scientific discoveries go, this is up there with finding a way to split the atom,” says Prof Geoff Taylor, director of the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP).
In the future, the entire roof of your house could be a solar panel, and you could harness the power of the sun to charge your mobile phone while on a remote bushwalk, thanks to cheap, printable solar cells.

Work is underway to perfect the “printing” of a film-like layer of solar cells that can be applied cheaply to hard or flexible surfaces to generate electricity from sunlight. Continue reading Victoria in race to print solar cells→
A glimpse of a rare self-portrait by one of Australia’s most highly regarded artists has emerged from what appeared to be a blank canvas—thanks to researchers at the Australian Synchrotron.

Solving the problem of how to store energy is essential for a future run on renewables.
That’s why promising materials for hydrogen fuel cells and high capacity, long-lived batteries are being explored at the atomic level by the Australian Synchrotron.
