DailyDirt: Like Water (Or Oil) Off A Duck's Back...

- The surface of a material with water repellent nano-structures can create a "lotus leaf effect" that exhibits superhydrophobicity, repelling water and making a self-cleaning mechanism. Mimicking these surface textures is possible, and artificially hydrophobic surfaces could have a variety of practical applications (but maintaining nano-structures in real-world conditions can be a challenge).

- A superomniphobic coating that repels not just water, but oils and even non-Newtonian liquids, is being developed in Michigan. While most folks think of stain-free clothing, this kind of coating will probably be better suited for other kinds of protective gear (eg. haz-mat suits) and other one-time use items. [url]
- Superhydrophobic surfaces are interesting for a bunch of reasons -- you can imagine self-cleaning solar panels or airplane wings that won't need de-icing. One more interesting application: improving the energy efficiency of steam turbine generators. [url]
