Dear Colleagues, We are organizing a session at Goldschmidt conference 2021, which will be held at Lyon, 4-9 July. Session 6J : Theme 6 (Nano to Microscale Processes) "Crystallization Pathways in Geochemistry, Biomineralization and Materials Science" We invite you all to submit an abstract before the deadline: 26 February (23:59 CET). Goldschmidt2021 will be in a hybrid format, combining an onsite meeting for delegates who can travel, with an online meeting for those who cannot, while aiming to promote as much interaction as possible between the two types of delegates Keynote speaker : Prof. Peter Fratzl, Max Planck Institute of Colloids and Interfaces, Germany For information see: https://2021.goldschmidt.info/goldschmidt/2021/meetingapp.cgi/Session/2109<https://urldefense.com/v3/__https:/2021.goldschmidt.info/goldschmidt/2021/meetingapp.cgi/Session/2109__;!!P4SdNyxKAPE!U5Y7g0vxeTYt4WtSbXPKSCAAVBWaXGDUJmwRYc4vHaslfJRvwoSwo6rGPetUSGobjCqRPPLR$> You can submit an abstract at the following website: https://2021.goldschmidt.info/goldschmidt/2021/cfp.cgi "Crystallization Pathways in Geochemistry, Biomineralization and Materials Science" Nature exhibits incredible control over the formation of minerals from the bottom-up, which in turn inspires the design of new materials. This sophisticated control is usually attributed to the mineralization environment and the presence of additives, with elemental and isotopic fractionation providing important signatures for these mechanisms/conditions. Our understanding of crystal formation pathways has expanded in recent decades; yet, the challenge remains to present a detailed picture describing the molecular-scale assembly and transformation of precursor phases, and to understand the underlying complex energy landscapes which lead to crystallization. This session will bring together interdisciplinary researchers to discuss common features of crystallization pathways and the thermodynamics and kinetics which control them. We welcome contributions on: 1) Molecular-scale insights into nucleation and growth; 2) The role of complexes, clusters and amorphous precursors in the formation of mineral phases; 3) The interplay between biological systems and mineral formation; 4) The role of geochemical signatures in determining mineral (trans)formation; 5) The control of additives, surfaces and confinement on the kinetics and pathways to crystalline phases; 6) Critical evaluation of theoretical frameworks to predict crystallization pathways; and, 7) New experimental and computational techniques to explore assembly and growth, and to determine energy landscapes. We seek contributions from diverse approaches and perspectives, such as direct observation, computational modelling across length and time scales, in vitro precipitation experiments, in vivo-studies of biomineral producing organisms, and inference from natural archives. Submissions from early career researchers are especially welcome.
