Themal/ mechanical stress-induced dynamic cracks in MOF membranes dynamically healed using nanoparticles

"spatiotemporal mismatch between dynamic crack formation/ point-by-point healing accuracy causes large healing zone, increased membrane thickness, mass transfer resistance... adaptive healing by creating patiotemporal harmony between crack generation/ healing... in situ formed nanoparticles immediately fill crack gaps... retained satisfactory separation performances for azeotropic mixtures... 85% energy consumption saved... separation durability improved >2 orders of magnitude"
