Tree-frog-inspired osmocapillary adhesive bonding to diverse substrates
Zefan Shao, Rui Ji, Qihan Liu
The performance of conventional pressure-sensitive adhesives (PSA) critically relies on the wetting of the adhesive over the substrate. When the wetting is hindered by low surface-…

Beyond von Mises Truss Models: Emergent Bistability in Mechanical Metamaterials
Md Nahid Hasan, Taylor E. Greenwood, Sharat Paul +4
We observe and analyze the phenomenon of bistability emergent from cooperative stiffening in hyper-elastic metamaterials. Using experimental and numerical results of identical geom…

Independent characterization of the elastic and the mixing parts of hydrogel osmotic pressure
Zefan Shao, Qihan Liu
Osmotic pressure is the driving force for the swelling of hydrogels. The hydrogel osmotic pressure can be decomposed into two parts: the mixing part due to polymer-solvent interact…
