The outstanding and extraordinary properties and features particularly emerging from micro- and nano-scale materials and structures are called for in many applications in mechanics, electronics, photonics, and energy and biological engineering. However, the low production throughput, unstandardized fabrication protocols, and limited applicability have been a roadblock to step toward mass-customized and application-specific nanomanufacturing from lab-scale nanofabrication. This seminar will address these issues while focusing on two main topics: (1) how micro/nano-scale structures and materials can be ‘complementarily’ assembled into more functional hybrid architectures having broader applicability; and (2) how these architectures can be engineered in a continuous and scalable way to increase the manufacturing throughput towards commercially-feasible level. In part one of this talk, carbon nanotubes, graphene, and metal oxide nanowires will be considered as small-scale building blocks and functional components. In the second part, a series of continuous, scalable, and high-throughput micro/nano-manufacturing techniques based around roll-to-roll lithography and seamless and template-free nanopatterning will be presented. Along with tangible applications involving energy conversion, sensing, functional surfaces, electronics, photonics, and plasmonics, we will also discuss how bottom-up-grown nanostructures and top-down nanopatterning methods can be further mingled with each other towards application multiscale and multidimensional nanoarchitectures.
Dr. Jong G. Ok is an assistant professor in Mechanical and Automotive Engineering at Seoul National University of Science and Technology. He received B.S. and M.S. degrees in Mechanical and Aerospace Engineering from Seoul National University in 2002 and 2007, respectively, and received his Ph.D. degree in Mechanical Engineering at the University of Michigan in 2013. He served as a research fellow in Electrical Engineering and Computer Science at the University of Michigan in 2013, and worked as a research staff at Samsung Advanced Institute of Technology in 2013-2014. His research interests involve the continuous and scalable nanomanufacturing technologies highlighted by rollable nanofabrication and template-free nanopatterning, and the hybrid functional nanostructures comprising carbon nanotubes, graphene, and metal oxide nanowires, for photonic, electronic, sensing, and energy conversion devices.
He has authored over 38 international journal papers and 81 conference articles including 10 invited ones. He was awarded the Graduate Student Best Paper Award for his master work, and was a recipient of the Departmental Fellowship at the University of Michigan.
