Overcoming Van der Waals Forces in reconfigurable nanostructures
Wang Zhang, Hao Wang, Alvin T. L. Tan +11
Reconfigurable metamaterials require constituent nanostructures to demonstrate switching of shapes with external stimuli. For generality, such nanostructures would touch and stick…

Crack formation in wet colloidal pillars
Justin Beroz, Alvin T. L. Tan, Ken Kamrin +1
We investigate the initiation of cracks in vertically freestanding water-saturated colloidal pillars constructed using a direct-write technique. Paradoxically, the cracks form duri…
