Superomniphobic Surfaces: Design & Applications
October 9, 2020 @ 10:00 am - 11:00 am
Recent years have seen significant advances in understanding super-repellent surfaces, i.e., surfaces with extreme repellency to liquids. Surfaces with extreme repellency to water are considered to be superhydrophobic. Surfaces with extreme repellency to virtually any liquid – aqueous or organic; Newtonian or non-Newtonian; with low or high viscosity; with low or high surface tension; acids, bases or solvents; monomers, oligomers or polymers etc. – are considered to be superomniphobic. In this presentation, I will discuss the fundamental physical and chemical principles of designing superomniphobic surfaces. Building on these fundamental principles, I will discuss our work on utilizing superomniphobic surfaces for applications including chemical shielding, inexpensive sensors, anti-thrombotic implants, and enhanced condensation heat transfer.
Dr. Kota received his PhD in Mechanical Engineering from the University of Maryland. Prior to joining Mechanical and Aerospace Engineering at North Carolina State University as an Assistant Professor, he was a Postdoctoral Fellow in Materials Science and Engineering at the University of Michigan and an Assistant Professor in Mechanical Engineering at Colorado State University. He received the 3M non-tenured faculty award (2019), the NSF Career Award (2018), the George T. Abell Outstanding Early-Career Faculty Award (2018), the Teaching Excellence Award from CSU (2016), and the Summer Faculty Fellowship from AFOSR (2016). His work has so far resulted in 6 patents and about 48 journal publications, which were cited 3600+ times, and were highlighted by Bloomberg TV, NBC News, Wall Street Journal, Washington Times, Forbes etc.
