TL;DR: Theory and experiment are presented to show that an interface between two soft materials under compression can form creases, a type of bifurcation distinct from wrinkles.

TL;DR: In this article, the authors show that for a solution of thickness of 50 microns adhesion energy of 50 Jm−2 is attained in 60 s. They illustrate this concept using two pieces of polyacrylamide hydrogels as adherends, an aqueous solution of cellulose as stitch polymers, and a change in the pH in the cellulose solution as a trigger.

TL;DR: In this article, the authors show that the off-axis stripes compromise the elastic energy of the inplane and antiplane deformation, and that the transition between the along-axis and the offaxis stripes obeys the Landau theory of phase transition of the second kind.

TL;DR: The approach is demonstrated by using a hydrogel that dissipates a large amount of energy during separation, forms strong and interlinks with the soft tissues, and degrades by breaking cross-links, and achieves initial adhesion energies of 300-700 J/m2 when adhered to different tissues.

TL;DR: In this article, the authors describe elastic leak using a theoretical model, and watch a seal deform and leak with a transparent experimental setup, showing that the critical fluid pressure for elastic leak depends on the geometry and constraint of the seal, but is insensitive to the rate at which the fluid is injected.
