"...a new, permanent, multi-purpose coating technology that will prevent your spectacles, car windscreen or bathroom mirror fogging up ever again...
...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."
