Description:About the Seminar\n\nMany biopolymers not only have advanced me
 chanical properties such as high modulus\, toughness\, and elasticity\, bu
 t more importantly\, exhibit dynamic characteristics including adaptive\, 
 malleable\, and self-healing properties. Following inspirations from the N
 ature\, Guan lab has developed various biomimetic soft materials imbued wi
 th active and dynamic properties. In one system\, we have designed a serie
 s of biomimetic modular polymers with folded nano-domains as the repeat un
 its. In another example\, we have developed strong and autonomous self-hea
 ling polymers using various supramolecular and dynamic covalent interactio
 ns. In contrast to previous designs\, our system spontaneously self-heals 
 as a single-component solid at ambient conditions without the need of any 
 external stimulus\, healing agent\, plasticizer\, or solvent.  Recently\,
  we have also made significant progress in dissipative self-assembly of ac
 tive materials. The overarching concept for all these projects is to build
  a direct link between microscopic molecular properties and macroscopic bu
 lk performance. In this talk\, I will discuss the design\, synthesis\, and
  property studies of these dynamic polymers including adaptive\, active\, 
 and self-healing materials.\n\nAbout the Speaker \n\nZhibin Guan obtained
  his B.S. and M.S. degrees from Peking University. He received his Ph.D. d
 egree in 1994 at the University of North Carolina\, Chapel Hill. Following
  a postdoctoral stint at Caltech and a short career at DuPont\, in 2000 he
  joined the faculty of the Department of Chemistry at UC Irvine as an assi
 stant professor. He was promoted to Associate Professor with tenure in 200
 4\, and to Full Professor in 2006. From 2006\, he also became affiliated f
 aculty of the Department of Biomedical Engineering\, the Department of Che
 mical and Biomolecular Engineering\, and the Department of Material Scienc
 e at UC Irvine. He has received recognition of his research with several a
 wards and fellowships\, including the Japan Society for the Promotion of S
 cience (JSPS) Fellowship\, the Humboldt Bessel Research Award\, the Camill
 e Dreyfus Teacher-Scholar Award\, the NSF CAREER Award\, the Beckman Young
  Investigator Award\, and an elected Fellow of the American Association fo
 r the Advancement of Science. His research work has been featured many tim
 es in scientific journals and newspapers such as C&amp\;EN News\, Washingt
 on Post\, Wall Street Journal\, Los Angeles Times\, CNN\, Forbes\, etc. He
  served as the Chair for the 2018 Bioinspired Materials Gordon Research Co
 nference in Les Diablerets\, Switzerland. 4:00 pm
