I like the look of this, posted at WUWT. Glass is always a problem keeping dry and clean in a wide field of usage. Especially good for cameras and telescopes. Cooltech: a nanoscale foglifter and frost inhibitor coating would be especially great for the marine industry.
From the American Chemical Society, something interesting.
A new anti-frost and anti-fog coating for glass
In an advance toward glass that remains clear under the harshest of conditions, scientists are reporting development of a new water-repellant coating that resists both fogging and frosting. Their research on the coating, which could have uses ranging from automobile windshields to camera lenses, appears in the journal ACS Nano.
Michael F. Rubner, Robert E. Cohen and colleagues point out that anti-fogging coatings that absorb water have been the focus of attention lately because of their ability to reduce light scattering and the resultant distortion caused by condensation. However, under extreme fogging conditions, these surfaces may frost and become foggy. They set out to make a better coating to withstand the aggressive conditions.
