Hidden art revealed

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.

Fresh Science 2010

Each year we identify early-career scientists with a discovery and bring them to Melbourne for a communication boot camp. Here are some of their stories.

Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have developed liquid inks based on quantum dots that can be used to print such devices and in the first demonstration of their technology have produced tiny lasers. Quantum dots are made of semiconductor material grown as nanometre-sized crystals, around a millionth of a millimetre in diameter. The laser colour they produce can be selectively tuned by varying their size.

Cling wrap captures CO2

High tech cling wraps that ‘sieve out’ carbon dioxide from waste gases can help save the world, says Melbourne University chemical engineer, Colin Scholes who developed the technology. The membranes can be fitted to existing chimneys where they capture CO2 for removal and storage. Not only are the new membranes efficient, they are also relatively cheap to produce. They are already being tested on brown coal power stations in Victoria’s La Trobe Valley, Colin says. “We are hoping these membranes will cut emissions from power stations by up to 90 per cent.”

Goanna team finds software bugs before they bite

nicta_Goanna_pg 6Software bugs are expensive. Typically, software developers waste around a quarter of their time testing and debugging programs. The later bugs are detected in the software development process the more expensive they are, and the more they delay the product launch. This is especially true in the case of embedded systems software which has to be developed at the same time as the hardware. If a bug gets through, it may mean millions of dollars is spent recalling the product.
