three panel comparison

In the image, the left panel is a directional slippery rough surface (SRS, this study), the middle panel is a slippery liquid-infused porous surface (SLIPS) and the right panel is a superhydrophobic surface. This image shows a comparison of water harvesting performance of SRS vs other state-of-the-art liquid repellent surfaces.
