“Bumpy” surfaces could lead to self-cleaning windows

Ohio State University engineers are designing surfaces with nanometer high bumps that could result in super-slick, water-repellent surfaces that mimic the texture of lotus leaves.

They could allow manufacturers to make self-cleaning windows or reduce friction between moving parts in micro or nano-machines that can’t be lubricated by normal means.
