Julius Koettgen, Ab initio calculation of the attempt frequency for oxygen diffusion in pure and samarium doped ceria, 114th General Assembly of the German Bunsen Society for Physical Chemistry (Bunsentagung 2015), Bochum

Conferences

I presented my research in talks at international conferences, including ICACC in Daytona Beach, Florida and SSI‑20 in Keystone, Colorado and gave a lecture in the Department of Materials Science and Engineering at Seoul National University, South Korea. I presented two webinars for the Joint Center for Energy Storage Research, one of the US Department of Energy's Energy Innovation Hubs.

Moreover, I planned and executed the conference “Defects and diffusion in solids: Application of new theoretical concepts”. This conference was sponsored by the German Bunsen Society for Physical Chemistry and involved 90 international participants. I led a team as the main organizer and, additionally, created a poster and website, promoted the event on social media and in the Bunsen magazine, and prepared an original film for the conference, which showcased the topics of the posters and upcoming presentations.
