Seminar Abstract

In this talk, we discuss some of my research group’s recent progress in engineering surfaces for enhanced functionalilty. In the first part of the talk, we focus on optoelectronic applications where optical properties such as broadband and broad angle antireflection as well as haze.  We discuss functionalities such as self-cleaning, stain-resistance, and anti-fogging.  Next, we discuss enhancing heat transfer in boiling by nanopillar arrays.  We discuss how nanopillar arrays enhance critical heat flux through increased rewetting. We also cover major challenges with the issue of mechanical durability in these surfaces and potential strategies for addressing these issues.  The creation of durable, multifunctional surfaces may have a wide variety of applications in optoelectronic devices and heat transfer.
