World's first discovery of liquid directional steering on a bio-inspired surface

Inspired by a kind of tree leaf, scientists at City University of Hong Kong (CityU) discovered that the spreading direction of different liquids deposited on the same surface can be steered, solving a challenge that has remained for over two centuries. This breakthrough could ignite a new wave of using 3D surface structures for intelligent liquid manipulation with profound implications for various scientific and industrial applications, such as fluidics design and heat transfer enhancement.
