The uses of rotary systems, e.g., centrifuges or evaporators, are commonplace in separations, but much less explored as the means of controlling the outcomes of chemical reactions or molecular-scale self-assembly processes. Nevertheless, the idea of setting a reaction vessel on spinning is appealing because rotation can generate centripetal and shear forces that could be hard to maintain in a stationary frame of reference. In my talk, I will discuss how this concept can be used to couple macroscopic rotation to events taking place at much smaller scales, down to the molecular. I will illustrate how rotation can mediate self-organization of complex fluidic reactors (driving multistep reaction sequences), affect molecular conformations and enhance crystallization processes, or set up microgravity conditions for levitating reaction units. I will also discuss examples of non-equilibrium self-assembly in which rotation imposes confining potentials and can establish unusual 3D fluidic traps.
