Nanoparticle deposition in a sand-packed 2D experimental setup. (a) Comparison of transport of calcium chloride solutions and concentrated FeOx suspensions. (b) Image of the 2D model after application of the proposed strategy. (c) Representative SEM micrographs of sand collected outside and (d) inside the target zone, the latter covered with nanoparticles after immobilization of nano-FeOx due to the application of the proposed strategy.
