This lecture will present the des ign of a novel class of reconfigurable materials that use ‘hairy’ surfaces bearing arrays of nanostructures put in motion by environment-responsive gels. Their unique hybrid architecture\, and chemical and mechanical prope rties can be optimized to confer a wide range of adaptive behaviors. Using both experimental and modeling approaches\, we are developing these hydro gel-actuated integrated responsive systems (HAIRS) as new materials with r eversible optical and wetting properties\, as a multifunctional platform f or controlling cell differentiation and function\, and as a first homeosta tic system with autonomous self-regulation. The extension of these princip les to the design of unique liquid crystal elastomer microstructures capab le of a broad range of hierarchical\, even mechanically unfavored deformat ion behaviors with applications in switchable adhesion\, information encry ption\, autonomous antennae\, energy harvesting\, soft robotics\, and smar t buildings will be discussed.\n\n \n\nBio:\n\nJoanna Aizenberg is the Amy Smith Berylson Professor of Materials Science and Professor of Chemistry and Chemical Biology at Harvard University. She received the B.S. degree i n Chemistry from Moscow State University\, and the Ph.D. degree in Structu ral Biology from the Weizmann Institute of Science. She was a postdoctoral fellow at Harvard and worked nearly a decade at Bell Labs\, prior to join ing Harvard. The Aizenberg lab's research is aimed at understanding some o f the basic principles of biological architecture and the economy with whi ch nature solves complex problems in the design of multifunctional\, adapt ive materials. These biological principles are then used as guidance in de veloping new\, bio-inspired synthetic routes and nanofabrication strategie s that would lead to advanced materials and devices\, with broad implicati ons in fields ranging from architecture to energy efficiency to medicine. Research topics of interest include biomimetics\, smart materials\, wettin g phenomena\, bio-nano interfaces\, self-assembly\, surface chemistry\, st ructural color\, metamaterials and catalysis. Aizenberg is elected to the National Academy of Sciences\, National Academy of Engineering\, American Academy of Arts and Sciences\, American Philosophical Society\, American A ssociation for the Advancement of Science\; and she is a Fellow of the Ame rican Physical Society\, Materials Research Society and External Member of the Max Planck Society. Dr. Aizenberg’s select awards include: MRS Medal\ ; ACS National Award in Colloid Chemistry\; Kavli Innovations in Chemistry Leader Award\, ACS\; Fred Kavli Distinguished Lectureship in Nanoscience\ , MRS\; Ronald Breslow Award for the Achievement in Biomimetic Chemistry\, ACS\; and Harvard’s Ledlie Prize for the most valuable contribution to sc ience. She has >370 publications\, >100 issued patents\, and is a Founder of five start-up companies.\n DTSTART:20260430T170000Z DTEND:20260430T183000Z LOCATION:OM 10\, Maass Chemistry Building\, CA\, QC\, Montreal\, H3A 0B8\, 801 rue Sherbrooke Ouest SUMMARY:McGill Chemical Society Seminar Series-Joanna Aizenberg: Multifunct ional dynamic materials with self-regulation URL:https://www.mcgill.ca/channels/channels/event/mcgill-chemical-society-s eminar-series-joanna-aizenberg-multifunctional-dynamic-materials-self-3726 13 END:VEVENT END:VCALENDAR
