The ECA kindly invites you to the 7th ECA Lunch webinar:

Abstract
According to the Oxford English Dictionary a phase diagram is “a diagram which represents the limits of stability of the various phases of a chemical system at equilibrium, with respect to two or more variables.” In high-pressure research these variables are most commonly referred to as temperature and pressure, for a given chemical composition. This definition, however, does not apply to the majority of simple molecular compounds consisting of light elements, including almost all organic compounds. These systems are metastable at any given thermodynamic conditions, as they never correspond to the Gibbs free energy minimum. In spite of that, metastable states are often promising technological materials. Moreover, dynamic compression experiments have recently demonstrated how the experimentally observed phase boundaries depend on transition kinetics. Hence, navigating the energetic landscape of highly polymorphic systems can lead to ‘dynamic phase diagrams’ or ‘metastable phase diagrams’ (transitional diagrams), which do not conform to the quoted definition, but can be extremely interesting for technological applications or fundamental studies. Throughout the talk, concepts will be illustrated by use cases from literature and own research.

About the ECA Lunch webinars:

The ECA lunch webinars with an educational or scientific focus were invented following the strong wish to strengthen and vitalize the European crystallographic community. They are a monthly webinar series by the European Crystallographic Association (ECA) and involve all GIGs/SIGs.

The webinars are organized in an online setting such as Zoom (45min + 15min Q&A) and take place every first or second (depending on the schedule of other ECA activities) Thursday of a month at lunchtime (1:00 PM CET). Webinars will be announced via social media, mailing list, and here.

The webinars are organized by a steering committee of GIG01-members:
Breternitz, Joachim
Gaidamaka, Anna
Germann, Luzia
Hans, Philipp
Mazzeo, Paolo P.
Morana, Marta
Pisacic, Mateja

 

Advisory board:
Heinemann, Udo
van der Lee, Arie
