🫧 Osmotic Microcapsule: Water Flux, Shell Elasticity and Rupture Strain (2D)

Cross-section of two elastic semipermeable microcapsules in a bath. Set the bath and interior concentration, temperature, shell stiffness, water permeability and rupture strain, and see the capsules swell or shrink until osmotic and elastic pressure balance, or burst. Van Hoff pressure, equilibrium radius, solute conservation and the free-swelling limit are checked. A 2D companion of the 3D osmotic capsule laboratory.
