The caption of the cover for Issue 21, Volume 22, 2010, omitted correct credit for the image and is corrected as follows:
The cover shows the sophisticated surface design of the floating water fern Salvinia. The unique surface architecture is composed of complex hydrophobic eggbeater-shaped hairs with hydrophilic terminal cells. The evenly distributed hydrophilic patches stabilize the air layer by pinning the air/water interface in place. The paradox combination of hydrophilic patches on superhydrophobic surfaces (the “Salvinia Effect”) provides an innovative concept for smart biomimetic surfaces in maritime coatings and underwater applications, as reported by Wilhelm Barthlott, Thomas Schimmel, and co-workers on p. 2325.
