DESCRIPTION:Prof. Chang-Hwan Choi\nDepartment of Mechanical Engineering\, 
 Stevens Institute of Technology\nHoboken\, New Jersey\, USA\nAbstract:\nNa
 ture\, such as plants\, insects\, and marine animals\, uses micro/nano-tex
 tured surfaces in their components (e.g.\, leaves\, wings\, eyes\, legs\, 
 and skins) for multiple purposes\, such as water-repellency\, anti-adhesiv
 eness\, and self-cleanness. Such multifunctional surface properties are at
 tributed to three-dimensional surface structures with modulated surface we
 ttability. Especially\, hydrophobic surface structures create a composite 
 interface with liquid by retaining air between the structures\, minimizing
  the contact area with liquid. Such non-wetting surface property\, so-call
 ed superhydrophobicity\, can offer numerous application potentials\, such 
 as hydrodynamic drag reduction\, anti-biofouling\, anti-corrosion\, anti-f
 ogging\, anti-frosting\, and anti-icing. Over the last couple of decades\
 , we have witnessed a significant advancement in the understanding of surf
 ace superhydrophobicity as well as the design\, fabrication\, and applicat
 ions of superhydrophobic coatings/surfaces/materials. In this talk\, the d
 esigns\, fabrications\, and applications of superhydrophobic surfaces for 
 multifunctionalities will be presented\, including hydrodynamic friction r
 eduction\, anti-biofouling\, anti-corrosion\, and anti-icing. Future poten
 tial applications of the superhydrophobic surfaces will also be discussed 
 briefly\, including self-assembly of nanomaterials and nanofluidic energy 
 harvesting.Bio: Dr. Chang-Hwan Choi is an Associate Professor in the Depar
 tment of Mechanical Engineering at the Stevens Institute of Technology. He
  acquired his BS (1995) and MS (1997) in Mechanical & Aerospace Engineerin
 g from Seoul National University in Korea. He also earned his MS in Fluids
 \, Thermal\, and Chemical Processes from Brown University in 2002. Dr. Cho
 i received his PhD in Mechanical Engineering from the University of Califo
 rnia at Los Angeles (UCLA) in 2006\, specializing in MEMS/Nanotechnology a
 nd minoring in Fluid Mechanics and Biomedical Engineering. He has two-year
  (1996\, 2000) work experience at Korea Aerospace Research Institute and t
 hree-year (1997-1999) teaching experience at Chandrakasem Rajabhat Univers
 ity in Thailand. His research activities include large-area nanopatterning
  and nanofabrication\, fluid physics and heat transfer at nanoscale interf
 aces\, self-assembly of nanomaterials\, nanofluidic energy harvesting\, an
 d cell-material interactions\, funded by various federal agencies in US (N
 SF\, DARPA\, ONR\, ARMY\, and DOE) and industries. He is a recipient of th
 e 2010 Young Investigator Program (YIP) award by the US Office of Naval Re
 search (ONR) for his efforts in the development of hydrodynamically-effici
 ent anti-corrosion surfaces\, which was also highlighted in Nature (http:/
 /www.nature.com/naturejobs/2010/100520/pdf/nj7296-385a.pdf). He was also s
 elected as one of Nanotechnology Thought Leaders in 2010 by AZoNano (The A
  to Z of Nanotechnology). In 2013\, he was designated one of the eight US 
 delegates to attend the CRDF Global Workshop to present and discuss the de
 velopments in energy research and collaboration between the US and foreign
  countries.
