Surface forces Insights into underwater adhesion and electrical double layer in concentrated electrolytes
Joelle Frechette, Chemical and Biomolecular Engineering, University of California Berkeley
Understanding and harnessing interactions between materials under confinement provides design strategies for coatings, recycling, batteries, and biomaterials. This presentation will discuss our efforts to connect intermolecular forces to macroscopic mechanical response to better understand how soft materials make contact and adhere under dynamic conditions as well as to elucidate the electrical double layer under confinement. In particular, we will discuss the formation (and suppression) of interfacial instabilities in adhesion, the role of hydrogen bonding in underwater adhesion, and the structure of the electrical double layer in highly concentrated aqueous electrolytes.
Bio. Joelle Frechette received her PhD from Princeton University in Chemical Engineering and Materials Science studying surface forces and adhesion in electrochemical environment. She joined Johns Hopkins University in 2006 and moved to UC Berkeley in 2021. She was awarded the NSF CAREER award, the 3M untenured faculty award, the ONR Young Investigator award, and was elected as a Fellow of the American Chemical Society in 2017. Her research interests include: adhesion in fluid environments, particles at fluid interfaces, and surface force measurements.
