Hydraulic Pressure-Programmed Molecular Transport in Tough Hydrogels. [PDF]
Adv Sci (Weinh)Hydraulic pressure is introduced as a programmable parameter for regulating molecular transport in tough hydrogel membranes. Reversing the pressure direction accelerates or slows transport, tuning characteristic transport times over a 65‐fold range while achieving molecular separation and controlled delivery.
