Online seminar: Reactions, materials and assemblies under rotation

---

The AGH UST Academic Center for Materials and Nanotechnology invites to a virtual seminar in the series “Krakow Condensed Matter Seminar” which will be held on June 2^nd, 2021, at 9.00 am.

A lecture entitled “Reactions, materials and assemblies under rotation” will be presented by Professor Bartosz A. Grzybowski (UNIST/IBS, South Korea & Polish Academy of Sciences)

Abstract

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.
