Making higher quality carbon fibre will be easier thanks to infrared analysis being used at the Australian Synchrotron.
The tough fibre, which is 10 times stronger and five times lighter than steel, is made by heating a synthetic product called polyacrylonitrile (PAN) in temperatures up to 600°C.
Some aircraft, high performance cars and the new electric BMW i3 are partly made with it. But slow and costly manufacturing methods currently deter the mass use of carbon fibre in automotive and aeronautical industries.
Japanese researchers are coming to Australia for our neutron beams. It’s helping them continue their research following the shutdown of all Japanese research reactors in the aftermath of the Great East Japan Earthquake. And it cements a friendship in beamline science that kickstarted Australian access to synchrotron light.

“Japan’s leadership in electronics, advanced manufacturing and computing complements Australia’s leadership in agriculture, health and minerals,” says the Australian Nuclear Science and Technology Organisation’s (ANSTO) Robert Robinson, who chaired an Australia Japan Neutron Science Workshop in 2013.
The collaboration is contributing to research into: hard magnets for electric cars; new high density plastics; superconducting cables for the ITER fusion reactor; and the structure of a range of biological molecules.

James Whisstock and his Monash University colleagues have uncovered how the bacterium Helicobacter pylori sticks to the stomach lining, where it can cause ulcers and sometimes cancer.

The role of Helicobacter in causing gastric ulcers was originally discovered by Australian Nobel Laureates Barry Marshall and Robin Warren.
The recent work by James and his team was performed using the Australian Synchrotron and showed how the Helicobacter pylori protein SabA interacts with sugars present on the cells that line the stomach.
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.

Our blood has a built-in system for breaking up heart attack-inducing clots—and we’re a step closer to drugs that could switch that system on at will.

Australian researchers have won the decades-long race to define the structure of plasminogen—a protein whose active form quickly dissolves blood clots.
The current crop of clot-busting drugs have many side effects, including bleeding and thinning of the blood, so harnessing the body’s own mechanism for clearing clots could offer a better way. Continue reading Clues to switching off your blood clots→
Australian detectives can now use a pinch of dirt or a speck of dust to help solve crimes, thanks to techniques developed at the Australian synchrotron.

Until recently, large sample sizes were needed to make this work. Continue reading Dirt solves murder mysteries→

South Australian researchers are using the Australian Synchrotron in their work on how to increase levels of iron and other micronutrients in staple grains such as rice and barley. The intense X-rays of the synchrotron can pinpoint where in the grain those micronutrients are found.
One third of the world’s population suffers from iron deficiency. One of the reasons for this is that more than three-quarters of the iron in rice is lost when the outer layers of the grain are removed during milling.
Enzo Lombi and Erica Donner from the Centre for Environmental Risk Assessment and Remediation at the University of South Australia are using the x-ray fluorescence microscopy (XFM) beam to probe grains of rice, barley and other staple grains that have been designed to boost levels of key micronutrients like iron.
The researchers use the intense synchrotron light to produce images showing concentrations of elements, like iron, copper, zinc and selenium.
One of the new plants they are studying is a strain of rice that has multiple copies of the gene for nicotianamine, which is involved in the long-distance transport of iron. The idea is that more iron will be moved into the inner layers of the rice grain.
The technique used by Enzo and Erica is the only one sensitive enough to determine the chemical form of these elements at the low levels found in cereal grains. It will show how much of the iron will be available when it reaches the consumer.
