Ice formation on aluminum (A), smooth silicon (B) and nanostructured silicon (C)
Icing on surfaces such as airplane fuselages could become a thing of the past, thanks to newly-developed nanostructured materials
Ice layer removal on aluminum (A), smooth silicon (B) and nanostructured silicon (C)
Much to the chagrin of those of us in the Northern Hemisphere, winter is once again on its way. For many of us, this means a return to icy roads, sidewalks, power lines and even airplane wings. Traditionally, the main methods of getting rid of this ice – or at least, keeping it under control – involve the use of salt and/or de-icing chemicals. Both of these are labor-intensive, environmentally-unfriendly, plus the salt kills grass and causes cars to rust. Now, however, researchers from Harvard University are developing nanostructured materials that could keep ice from ever forming on surfaces in the first place.
