School of Materials Seminar entitled "Towards Durable Hydrophobicity and Omniphobicity"
|Dates:||22 November 2017|
|Times:||14:00 - 15:00|
|What is it:||Seminar|

|Speaker:||Dr Nenad Miljkovic|
Micro and nanoengineered functional surfaces have recently received significant attention due to their ability to enhance the efficiency and performance of a variety of applications.
Although demonstrated on the lab scale, the successful integration of these surfaces into systems has been slow due mainly to issues related to poor longevity, unproven scalability,
and inability to handle working fluids having low surface tensions. Furthermore, the utilization of these surfaces in thermal domains has been even tougher due to the need to keep
coatings ultra-thin to avoid adding parasitic thermal resistances. In this talk, I will discuss fundamental studies of hydrophobic and omniphobic surface durability during both water
vapor condensation and a variety of fluid-surface interactions. Our studies provide key insights related to the design of smooth and rough functional surfaces and help pinpoint future
breakthroughs needed to improve the robustness and implementation of hydrophobic and omniphobic coatings.
At UIUC, Nenad leads the Energy Transport Research Laboratory (ETRL). The ETRL’s research has advanced the efficiency of various industrial processes including energy
(power generation, oil & gas, HVAC&R), water, transportation, and electronics cooling, by fundamentally altering thermal-fluid-surface interactions. Previous to this,
Nenad’s PhD work focused on the design and characterization of micro/nanostructured surfaces for enhanced condensation heat transfer. He is the recipient of the
National Science Foundation CAREER award, the Office of Naval Research Young Investigator Award, the American Chemical Society Petroleum Research Fund
Doctoral New Investigator Award, and the UK Royal Academy of Engineering Distinguished Visiting Fellowship.
