A Scalable Double‐Sided Wet Etching Strategy for Large‐Area Mushroom‐Shaped Bionic Adhesives

Advanced Science, EarlyView.
This work presents a scalable manufacturing strategy for high‐performance, large‐area, mushroom‐shaped bio‐inspired adhesives. Using a double‐sided wet etching process, the complex 3D metal molds are fabricated rapidly and controllably. The resulting adhesive structures exhibit strong, stable adhesion under various conditions, including atmosphere and ...

OFF-STAGNATION POINT TESTING IN PLASMA FACILITY

, 2015
Reentry space vehicles face extreme conditions of heat §ux when inter-acting with the atmosphere at hypersonic velocities. Stagnation point heat §ux is normally used as a reference for Thermal Protection Ma-terial (TPS) design; however, many critical ...

Evolution of disturbances in stagnation point flow [PDF]

, 1993
The evolution of three-dimensional disturbances in an incompressible three-dimensional stagnation-point flow in an inviscid fluid is investigated. Since it is not possible to apply classical normal mode analysis to the disturbance equations for the fully
