CO2 condensation onto alkanes: Unconventional cases of heterogeneous nucleation

Vortrag

...

Vortrag von Prof. Dr. Barbara Wyslouzil, The Ohio State University, USA.
Kurzbeschreibung der Veranstaltung In the usual picture of heterogeneous nucleation a liquid condenses onto an immiscible solid particle. Here, we examine heterogeneous nucleation of CO2 onto particles com-prised of n-pentane or n-hexane under conditions where CO2 should be a solid and the seed particles may be liquid or solid. Although CO2 almost always condensed un-der our experimental conditions, these experiments do not easily fit into the framework of standard heterogeneous nucleation experiments. Rather they explore unconven-tional regimes of heterogeneous nucleation in which the state of the seed particle may both affect whether deposition can proceed, and, in turn, be influenced by the presence of the condensing species.
