Let the light shine through: and no more spitting in your dive mask.

20.09.2004


Fogged up glasses, windscreens and bathroom mirrors may be a thing of the past.

Researchers have invented a new, permanent, multi-purpose coating technology that will prevent your spectacles, car windscreen or bathroom mirror fogging up ever again. The coating, called XeroCoat, also cuts out unwanted reflections from glass, letting more light through. Making it ideal for spectacles and improving the performance of solar cells and glasshouses.

University of Queensland physicists Michael Harvey and Paul Meredith developed this technology based upon thin films of nano-porous silica; this means that “the coating is a layer of glass full of tiny invisible bubbles, just like the foam on beer,” said Mr Harvey. “Because it’s made of glass it’s as hard as glass,” he said, giving the added benefit of a hard coating on items to prevent or reduce scratching. The whole production process is extremely simple, very low-cost and environmentally friendly. Queensland’s Sustainable Energy Innovation Fund, administered by the Environmental Protection Agency, recently awarded the team a grant to further develop the new coating.



Their support will allow trials of this technology to improve the efficiency of solar cells, with the first improved prototypes expected by January 2005. This research also won Michael Harvey a place amongst 15 other early-career scientists who have presented their work to the public and media as part of Fresh Science 2004. The winner will receive a study tour to the UK courtesy of the British Council.

Dr Meredith said existing technologies for applying anti-reflection coatings were all too expensive for the wide areas required for solar collector surfaces. “This innovation is set to revolutionise the use of solar energy by making it cheaper and more effective,” he said. Mr Harvey said that the new coating can be applied to many surfaces, including glass and plastics, and so permanently prevent these items fogging up. Current research is developing this anti-fogging, anti-reflection and scratch resistant coating for products such as spectacles, sunglasses, windscreens and bathroom mirrors.

The University of Queensland’s commercialisation arm, UniQuest, has formed a company, XeroCoat Pty Ltd, to develop and market this technology, offering a better coating solution than those currently available. As the technology develops, Mr Harvey expects that many more applications will emerge, including: enhancing food production by improving the function of greenhouses; scratch-proofing plastics; and improving the performance of high-rise building windows.

“One day soon we will see XeroCoat on products ranging from spectacles, swim and ski goggles to car windscreens and even bathroom mirrors. We are taking nanotechnology out of the lab and putting it in the bathroom,” Mr Harvey said.

Im Focus: Nuclear Pores Captured on Film

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

Im Focus: 2+1 is Not Always 3 - In the microworld unity is not always strength

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”

Im Focus: Tiny microbots that can clean up water

Researchers from the Max Planck Institute Stuttgart have developed self-propelled tiny ‘microbots’ that can remove lead or organic pollution from contaminated water.

Im Focus: ORNL researchers discover new state of water molecule

Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states.

In a paper published in Physical Review Letters, researchers at the Department of Energy's Oak Ridge National Laboratory describe a new tunneling state of...
