DESCRIPTION:Abstract:\n\nThe intermolecular interactions and surface charac
 teristics of materials significantly determine their physicochemical prope
 rties and functionalities. Much effort has been devoted to characterizing 
 the intermolecular and surface interactions (e.g.\, adhesion)\, especially
  noncovalent interactions\, in soft materials (e.g.\, surfactants\, polyme
 rs\, biopolymers) and biological systems. In this talk\, the basics of int
 ermolecular and surface forces and some commonly used nanomechanical techn
 iques will be briefly introduced. The recent progress on how we applied na
 nomechanical tools for quantifying the intermolecular and surface interact
 ions of polymer/biopolymer materials and biological systems (e.g.\, wet ad
 hesion of marine mussels) will be presented. Our recent studies have syste
 matically characterized the intermolecular and surface interaction mechani
 sms of mussel adhesives. The fundamental interaction mechanisms elucidated
  (e.g.\, biopolymer-metal ion coordination\, cation-π\, anion-π\, hydropho
 bic and hydrogen bonding interactions in aqueous media) have been further 
 applied for developing multifunctional soft materials (e.g.\, self-healing
  polymers/hydrogels\, wet adhesives) with various bioengineering applicati
 ons. These findings provide useful insights into biological self-assembly 
 processes and new approaches to develop multifunctional soft materials or 
 surfaces via tunable noncovalent interactions.\n\n \n\nBio:\n\nHongbo Zeng
  is a Professor in the Department of Chemical and Materials Engineering at
  the University of Alberta\, a Tier 1 Canada Research Chair in intermolecu
 lar forces and interfacial science\, a Fellow of the Canadian Academy of E
 ngineering\, and a fellow of the Royal Society of Chemistry. He was also e
 lected as a Fellow of the Royal Society of Canada recently. He received hi
 s BSc and MSc at Tsinghua University and PhD at the University of Californ
 ia\, Santa Barbara. Zeng’s research interests are in colloid and interface
  science\, functional materials & nanotechnology\, with a special focus on
  the intermolecular and surface interactions in soft materials and enginee
 ring processes. He has published one book and over 480 peer-reviewed journ
 al articles. His work has been recognized by many awards\, such as the CSC
 hE Innovation Award of the Chemical Institute of Canada\, Killam Professor
 ship\, the NSERC Steacie Fellowship and the van der Waals Prize. He serves
  as an Editor of the journal Advances in Colloid and Interface Science.\n
