Nature-inspired surface for water-energy nexus
Abstract： The recent outbreak of Coronavirus disease 2019 (COVID-19) recalls the paramount importance of harmonious co-existence between nature and humans. This talk focuses on how to seek nature’s principles and inspirations to guide the design and regulation of surface topological structures for addressing the grand challenges in the water-energy nexus. First, I will answer three important historical questions that underpin surface science and engineering, i.e., what’s the shortest contact time on superhydrophobic surfaces, how to achieve directional liquid flow on superhydrophilic surfaces, and how to achieve superwetting at extremely high surface temperatures? In the field of applied research, I will discuss how to fabricate wear-resistant superhydrophobic coatings on a large scale, as well as explore diverse applications in areas such as thermal cooling (complete suppression of the Leidenfrost effect observed in 1756), water harvesting, and energy harvesting.
