Dear colleagues, With an apology for cross-posting, we invite submissions for the symposium "Deep Planet Chemistry: Novel Phases and Reaction Pathways in Planetary Interiors" at the American Chemical Society (ACS) Fall 2026 Meeting, which will be held in Chicago, IL, August 23-27, 2026. This session aims to strengthen connections between high-pressure chemistry, planetary science, and materials under extreme conditions, and to highlight emerging research on the chemical and physical processes governing planetary interiors. We welcome contributions from experimental, theoretical, and computational researchers working on topics including, but not limited to: * High-pressure mineral physics and geochemistry * Transport properties and dynamical behavior of deep planetary materials * Ab initio simulations, machine-learning potentials, and multiscale modeling of extreme planetary environments * Laboratory and shock-compression studies relevant to planetary conditions Contributions from students and early-career researchers are especially welcome. The detailed session abstract is attached to this email. Confirmed Invited Speakers: Prof. Lars Stixrude (UCLA), Dr. Sebastien Hamel (LLNL), Dr. Mungo Frost (SLAC National Accelerator Laboratory) Abstract submission link: https://callforabstracts.acs.org/acsfall2026/GEOC Abstract deadline: March 30, 2026 Please feel free to share with any colleagues who you think may be interested in contributing to this session. Cheers, Suraj K Bajgain (on behalf of the session conveners) Suraj Bajgain, Salma Ahmed, Kyla de Villa, and Terry-Ann Suer ____________________________________________________ Assistant Professor Environmental Geology Program | Department of Marine and Earth Sciences The Water School, Florida Gulf Coast University, Fort Myers, FL office: The Water School (AB9), Room 333 P: 239.745.4687 E: sbajgain@fgcu.edu https://surajbajgain.weebly.com/ [cid:image001.png@01DCB52B.72878EE0] [cid:image002.png@01DCB52B.72878EE0] <https://www.facebook.com/FloridaGulfCoastUniversity/> [cid:image003.png@01DCB52B.72878EE0] <https://www.linkedin.com/school/florida-gulf-coast-university/> [cid:image004.png@01DCB52B.72878EE0] <https://twitter.com/fgcu/> [cid:image005.png@01DCB52B.72878EE0] <https://www.instagram.com/fgcu/?hl=en> Florida has a very broad public records law.
