Akademickie Centrum Materiałów i Nanotechnologii AGH zaprasza na wirtualne seminarium z cyklu „Krakow Condensed Matter Seminar”, które odbędzie się 2 czerwca 2021 r. o godz. 9.00.
Referat pt. Reactions, materials and assemblies under rotation wygłosi prof. Bartosz A. Grzybowski (UNIST/IBS, Korea Południowa; Instytut Chemii Organicznej Polskiej Akademii Nauk).
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.
