DESCRIPTION:Prof. Zhengmao Lu\, Energy Transport Advances Laboratory (ETA-
 Lab)\, Institute of Mechanical Engineering (IGM)\, School of Engineering (
 STI)\, EPFL\nAbstract: Fundamental understanding of phase change phenomena
 \, despite its great impact on the world’s energy and water systems\, ha
 s been limited\, mainly due to the difficulty of experimentally isolating 
 and characterizing interfacial thermal resistance. In the first part of my
  talk\, I will discuss how we overcame this challenge and elucidated a uni
 fied relationship for evaporative transport under different working condit
 ions. In the second part of my talk\, I will discuss how we leveraged the 
 obtained understanding to create high-performance passive cooling solution
 s. For thermal management of electronics\, we created a membrane-based hie
 rarchical evaporator and demonstrated a record high pure evaporation heat 
 flux for dielectric fluids. For temperature regulation of buildings and pe
 rishable goods\, our hydrogel-aerogel structures exhibited significantly l
 onger cooling time and delivered much higher cooling power by synergistica
 lly combining different cooling mechanisms. Overall\, we show that combini
 ng fundamental interfacial transport physics with novel materials and inte
 rface engineering enables unique opportunities for innovations toward more
  sustainable energy and water technologies.\n\nBiography: Zhengmao Lu is a
  Tenure Track Assistant Professor of Mechanical Engineering at EPFL. Previ
 ously\, Zhengmao was a postdoctoral scholar in the Department of Materials
  Science and Engineering at MIT with Prof. Jeffrey Grossman. He received h
 is Ph.D. and M.S. in Mechanical Engineering from MIT as well\, advised by 
 Prof. Evelyn Wang. At EPFL\, Zhengmao leads the Energy Transport Advances 
 Laboratory (η-Lab)\, aiming to obtain a deeper understanding of phase cha
 nge phenomena and develop more sustainable energy and water technologies b
 y optimizing interfacial transport. Zhengmao is a recipient of the Keck Tr
 avel Award in Thermal Sciences and the Outstanding Graduate Research Award
  from MIT Mechanical Engineering.\n\nRegister here.
