The synthesis of ordered, homogeneous porous grains is an expanding area of materials research. One strategy for their formation is to dry the spray of a complex mixture containing nanoparticles and templating agents . In this process, a continuous flow of micrometric droplets, made from the initial dilute solution, is dried along a hot tube in order to evaporate the solvent. Self-organisation of the constituents takes place during the evaporation.
