Shared data reveals radio bursts, and a lunch break

In May 2014, a team led by PhD candidate Emily Petroff from Swinburne University was the first to see ‘fast radio bursts’ (FRBs) live, using the Parkes radio telescope in central New South Wales. The search was triggered by signals found in recycled data. They also discovered that someone was opening the kitchen microwave.

Australian crystals clean gas, food, air…

Forty per cent of the energy consumed by industry is used to separate things— in natural gas production, mineral processing, food production, pollution control. The list goes on.

Each offers an application for Matthew Hill’s crystals. He has demonstrated that the space inside metal–organic frameworks (MOFs)—the world’s most porous materials—can be used as efficient and long-lasting filters.

By choosing different combinations of metals and plastics, Matthew’s CSIRO team can make a wide range of customised crystals. Then, using antimatter and synchrotron light, they map the internal pores, determine what each crystal can do and explore potential applications.

Clean water with crystals

Dr Cara Doherty, materials scientist, CSIRO, Melbourne

Dr Cara Doherty (credit: L’Oréal Australia) Cara Doherty is developing new technologies that could transform water filters, batteries and medical sensors, and clean up carbon emissions. And it all comes down to holes and surface area.

She has a vision for a new manufacturing industry for Australia. She works with crystals that are packed with… nothing. They’re highly porous sponges—down to a molecular level—and can be customised to absorb almost any molecule.

These crystals are metal–organic frameworks (MOFs). They can be challenging to make. And it’s also difficult to determine which crystal will be good for which job. But it’s even harder to deploy the crystals—to put them in the right place to do useful work.

Cara uses antimatter (positrons) and synchrotron light (X-rays) to measure the crystals and their properties. Then she uses her patented technique to imprint useful shapes for devices.

With the help of her L’Oréal For Women in Science Fellowship she will investigate how to take the next step: to develop the 3D structures that would be needed for a smart water filter.

Australia’s newest radio telescope

Fundamental questions about the Universe are set to be answered as a new radio telescope in outback Western Australia comes online, using multiple beam radio receiver technology to view the sky with unprecedented speed and sensitivity.

The Australian SKA Pathfinder (ASKAP), CSIRO’s newest telescope, uses innovative phased array feed receivers, also known as ‘radio cameras’, to capture images of radio-emitting galaxies in an area about the size of the Southern Cross—far more than can be seen with a traditional radio telescope.

Zebedee bounces around, mapping as he goes

Now you can map a mine, cave, building or forest just by walking through it with Zebedee in your hand.

CSIRO scientist Elliot Duff and his colleagues developed a spring-mounted hand-held laser scanner that can make 3D images of spaces previously impossible to map.

Small devices to fight a big disease

Detection of dangerous water-borne pathogens will soon be much easier, thanks to advances using microfluidic systems developed at the Melbourne Centre for Nanofabrication (MCN), the Victorian node of the Australian National Fabrication Facility (ANFF).

Microfluidics deals with the control and manipulation of fluids in tiny, constrained volumes, in order to perform scientific tasks. The advantages in such systems centre around the cost and effort savings associated with miniaturisation and automation.

Finding pulsars in the archives

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.

Next generation packaging

Melbourne-based manufacturing company RMAX is working with CSIRO to make a sustainable, and biodegradable, version of a product involved in the life-cycle of many of the things we buy.

They hope to cut the environmental impact of the nine thousand tonnes of expanded polystyrene (EPS) that ends up in Australian landfill every year.
