Dr. Thomas Schutzius, Dpt of Mechanical and Process Engineering, ETHZ Bio : Dr. Thomas Schutzius is a group leader (Micro- and Nanoscale Interfacial Transport Phenomena and Thermodynamics) in the Laboratory of Thermodynamics in Emerging Technologies at the Swiss Federal Institute of Technology in Zurich (ETH-Zurich). He received his B.S. and Ph.D. degrees from the Department of Mechanical Engineering at the University of Illinois at Chicago (UIC) in 2008 and 2013, respectively. During his graduate studies, he was the recipient of the Dean’s Scholar Award and the UIC Outstanding Thesis Award. Afterwards, he received the ETH fellowship, which provided full funding for his postdoctoral research at ETH-Zurich. His major research interests include interfacial phenomena, thermodynamics and surface science, surface micro/nanoengineering, liquid repellency, multiphase heat and mass transfer, and polymer composites, focusing on problems related to energy, environment, and manufacturing. |

At the interface of thermofluidics and rational materials engineering
The increased understanding of physical phenomena at short temporal and spatial scales coupled with the continued advancement of micro/nanofabrication technologies indicate a shift in engineering practice, in particular surface engineering, that will create new materials, techniques, devices, and applications. The discipline of Interfacial Phenomena and Processes, which lies at the intersection of chemistry, physics, and engineering, has and will continue to serve an important role in these advancements, by providing and producing a firm fundamental knowledge-base that surface engineers can build from (i.e., rational design rules). It is a broad research area and has implications for matters as diverse as energy conversion and transport, oil spill dynamics and mitigation, self-cleaning surfaces, drug delivery, pesticide spraying, microelectronics cooling, and three-dimensional nanoscale printing. Such work is already resulting in a series of innovative solutions for diverse applications including phase change heat transfer, liquid repellency, wound healing, icephobicity, and light absorption. While true, many of these surfaces and the associated interfacial processes are at their nascent state.
In this talk, I will present the development and application of our recent findings on interesting self-removal mechanisms of droplets and ice from engineered surfaces, i.e., superhydrophobic and icephobic behavior. For applications where design rules are clear, I will then show my perspective on the progress of large-area fabrication techniques of surfaces with hierarchical texture. In general, this work goes towards findings that add to our understanding of how droplet–surface interactions can prevent the accumulation of liquids or solids on surfaces and how these surfaces can be realized in real-world applications.
