Flexing Muscles: Hybrid Materials with Actuatable, Hierarchical Topography for Multifunctional Surface Design
Harnessing the emergence of unique transient morphologies could have potential in the design of multifunctional, actuatable materials for switchable adhesion, antifouling, cell manipulation, and liquid and particle transport surface.
Shape-Directed Micromotors via Catalytic Self-Electrophoresis
We showed how particle shape alone can induced and direct the motions of catalytic micromotors via chemically fueled electrokinetic flows.
Using Magnetic Fields to Control Elastic Sheets
Rotating magnetic fields can drive 2D elastic sheets, made of magnetic particles, to expand, contract, or twist.
Transitional Bonding in Colloidal Systems
The discovery of a new type of bonding in colloidal systems where nanoparticles diffuse and hold together colloidal crystals in the same way electrons do in metallic bonding.
