Photo-Switchable Cross-Linking in Polymer Gels: Effects on Surface Creasing and Network Relaxation during Swelling
Alyssa VanZanten, Surbhi Punhani-Schillinger, M. Reed Blocksome +5
Polymer gels with photo-responsive cross-links enable tunable mechanics and surface morphologies, making them promising for adaptive materials. While prior work on coumarin cross-l…
Rocking, Rolling, and Hopping: Exploring the Multi-motion Capabilities of Rigid and Soft Ellipsoidal Actuators
Shih-Yuan Chen, Michelle M. Driscoll
The problem of a rigid disk rolling down a ramp is a classic problem given to students in introductory mechanics courses. In contrast, systematic studies on the rolling behavior of…
Unconstrained dynamic gel swelling generates transient surface deformations
Alyssa VanZanten, Shih-Yuan Chen, Michelle M. Driscoll +1
Polymer gels are comprised of a three-dimensional, cross-linked network that can typically withstand the mechanical deformation associated with both swelling and de-swelling. Thus,…
Wobbling and Migrating Ferrofluid Droplets
Aaveg Aggarwal, Shih-Yuan Chen, Eleftherios Kirkinis +4
Active components incorporated in materials generate motion by inducing conformational changes in response to external fields. Magnetic fields are particularly interesting as they…
Restructuring a passive colloidal suspension using a rotationally driven particle
Shih-Yuan Chen, Hector Lopez-Rios, Monica Olvera de la Cruz +1
The interaction between passive and active/driven particles has introduced a new way to control colloidal suspension properties from particle aggregation to crystallization. Here,…
