Superomniphobic Surfaces: Design & Applications

Abstract:

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.

Biography:

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.
