Imagine a power station that’s literally sprayed onto your roof —and could match the colour of your tiles.
Thin film solar cells are thinner, cheaper and more versatile than the traditional silicon solar panels. Spray-on solar is a next step in the evolution of on-site power generation.
“These cells can be made with semiconductor dye materials, so you can match them to any colour or pattern you like—they’ll just convert that part of the solar spectrum into electricity. In the future we could have billboards that act as solar panels,” says Dr Gerry Wilson of CSIRO’s flexible electronics team.
New lubricants containing star-shaped polymers have hit the market, thanks to Australian polymer technology. Lubrizol Corporation has launched the first commercial products developed using CSIRO’s Reversible Addition Fragmentation chain Transfer (RAFT) polymer synthesis process.
CSIRO chemist Dr Ezio Rizzardo says the RAFT process allows much greater flexibility and potential for polymer synthesis, compared with conventional methods. “Conventional polymerisation is a relatively simple process with two ingredients: large amounts of monomer and a small amount of an initiating agent. You apply heat; a chain reaction starts and runs to completion, making polymer chains that can have widely varying lengths.” Continue reading Star-shaped polymers boost engine performance→
An inexpensive, environmentally friendly alternative to a toxic coating currently used in Australian naval helicopters has been developed at Monash University in collaboration with CAST Cooperative Research Centre in Melbourne.
The magnesium alloy used to house the gearbox of Royal Australian Navy SeaHawk helicopters is prone to severe corrosion in marine environments, costing millions of dollars in maintenance every year. To protect the alloy from corrosion, it is covered with a chrome-based coating that is toxic to humans and the environment.
LED lighting is sweeping the world. It’s energy efficient, long lasting, and could save users billions of dollars worldwide and dramatically reduce carbon emissions. But it’s still a young technology. Much more efficient lights are on the way.
CSIRO researchers are applying nanotechnology to drug delivery, medical body imaging, nerve repair, smart textiles and clothing, medical devices, plastic solar cells (see From plastic money to plastic electricity) and much more.
“Nanotechnology is not an industry—it is an enabling technology,” says Clive Davenport, leader of CSIRO’s Future Manufacturing Flagship.
Every new technology brings opportunities and threats. Nanotechnology is no exception. It has the potential to create new materials that will dramatically improve drug delivery, medical diagnostics, clean and efficient energy, computing and more. But nanoparticles could also have significant health and environmental impacts.
