Interface stabilization in adhesion caused by elastohydrodynamic deformation
Preetika Karnal, Yumo Wang, Anushka Jha +3
Interfacial instabilities are common phenomena observed during adhesion measurements involving viscoelastic polymers or fluids. Typical probe-tack adhesion measurements with soft a…
Adhesion of fluid infused silicone elastomer to glass
Anushka Jha, Preetika Karnal, Joelle Frechette
Elastomers swollen with non-polar fluids show potential as anti-adhesive materials. We study the effect of oil fraction and contact time on the adhesion between swollen spherical p…
Role of Hydrodynamic Drainage in Adhesion to Wet Surfaces
Rohini Gupta, Joelle Frechette
Tree frogs possess soft structured toe pads with channels that help squeeze out fluid from the region between the toe pad and the contacting surfaces. This structure enables them t…
Elastic deformation during dynamic force measurements in viscous fluids
Yumo Wang, Georgia Pilkington, Charles Dhong +1
Understanding and harnessing the coupling between lubrication pressure and elasticity provides materials design strategies for applications such as adhesives, coatings, microsensor…
Morphology of soft and slippery contact via fluid drainage
Yumo Wang, Joelle Frechette
The dynamic of contact formation between soft materials immersed in a fluid is accompanied by fluid drainage and elastic deformation. As a result, controlling the coupling between…
Elastic Deformation of Soft Coatings Due to Lubrication Forces
Yumo Wang, Matthew R. Tan, Joelle Frechette
Elastic deformation of rigid materials with soft coatings (stratified materials) due to lubrication forces can also alter the interpretation of dynamic surface forces measurements…
Micropatterned Charge Heterogeneities via Vapor Deposition of Aminosilanes
Christian Pick, Christopher Argento, German Drazer +1
Aminosilanes are routinely employed for charge reversal or to create coupling layers on oxide surfaces. We present a chemical vapor deposition method to pattern mica surfaces with…
Out-of-contact elastohydrodynamic deformation due to lubrication forces
Yumo Wang, Charles Dhong, Joelle Frechette
We characterize the spatiotemporal deformation of an elastic film during the radial drainage of fluid from a narrowing gap. Elastic deformation of the film takes the form of a dimp…
Coupled effects of applied load and surface structure on the viscous forces during peeling
Charles Dhong, Joelle Frechette
Tree frogs are able take advantage of an interconnected network of epithelial cells in their toe pads to modulate their adhesion to surfaces under dry, wet, and flooded environment…
Inertia and scaling in deterministic lateral displacement
Timothy J. Bowman, German Drazer, Joelle Frechette
The ability to separate and analyze chemical species with high resolution, sensitivity, and throughput is central to the development of microfluidics systems. Deterministic lateral…
Analysis of the trajectory of a sphere moving through a geometric constriction
Sumedh R. Risbud, Mingxiang Luo, Joelle Frechette +1
We present a numerical study of the effect that fluid and particle inertia have on the motion of suspended spherical particles through a geometric constriction to understand analog…
