Title: Everything SLIPS: Design of Novel Omniphobic Materials
Abstract:
Abstract:
Liquids entrapped within a nanostructured solid begin to exhibit unique behaviors often providing the surrounding material with unprecedented properties. Recently we have introduced a new technology to create self-healing, anti-fouling materials (so-called Slippery, Lubricant-Infused Porous Surfaces, or SLIPS). These bioinspired coatings, which mimic slippery surfaces of a pitcher plant, outperform state-of-the-art materials in their ability to resist ice and microbial adhesion, repel various simple and complex liquids, prevent marine fouling, or reduce drag. Generalized chemical design principles to create stable, shear-tolerant SLIPS on metals, ceramics, glass, fabrics and polymers will be discussed. We anticipate that slippery surfaces can find important applications as antifouling materials in medicine, construction, naval and aircraft industries, fluid handling and transportation, optical sensing, and as antifouling surfaces against highly contaminating media operating in extreme environments.
Bio:
Joanna Aizenberg received the M.S. degree in Chemistry from Moscow State University, and the Ph.D. degree in Structural Biology from the Weizmann Institute of Science. After spending nearly a decade at Bell Labs, Joanna joined Harvard University, where she is the Amy Smith Berylson Professor of Materials Science, Professor of Chemistry and Chemical Biology, Director of the Kavli Institute for Bionano Science and Technology and Platform Leader in the Wyss Institute for Biologically Inspired Engineering.
The Aizenberg lab's research is aimed at understanding some of the basic principles of biological architecture and the economy with which nature solves complex problems in the design of multifunctional, adaptive materials. These biological principles are then used as guidance in developing new, bio-inspired synthetic routes and nanofabrication strategies that would lead to advanced materials and devices, with broad implications in fields ranging from architecture to energy efficiency to medicine. Research topics of interest include biomimetics, smart materials, wetting phenomena, bio-nano interfaces, self-assembly, crystal engineering, surface chemistry, structural color and biomineralization.
Aizenberg is elected to the National Academy of Sciences, National Academy of Engineering, American Academy of Arts and Sciences, American Philosophical Society, American Association for the Advancement of Science; and she is a Fellow of the American Physical Society, Materials Research Society and External Member of the Max Planck Society. Dr. Aizenberg’s select awards include: MRS Medal, Kavli Innovations in Chemistry Leader Award, ACS; Fred Kavli Distinguished Lectureship in Nanoscience, MRS; Ronald Breslow Award for the Achievement in Biomimetic Chemistry, ACS; as well as ~50 Named and Distinguished Lectureships, and Harvard’s Ledlie Prize for the most valuable contribution to science. She has >230 publications, >60 issued patents, and is a Founder of four start-up companies.
