The research unit "Nanoscale processes and geomaterials properties" has been funded from 2007 to 2016 by the German Science Foundation (DFG) and the Austrian Science Fund (FWF).
The research included several closely interconnected projects such as (1) atomic structure, thermodynamic and kinetic properties of grain boundaries, (2) diffusion in polycrystals, (3) exsolution in mineral systems and (4) fluid assisted mineral replacement. Among others, projects addressed how grain- and phase boundaries are generated during homogeneous and heterogeneous nucleation, and how the network of grain and phase boundaries may evolve during thermally and stress induced re-crystallization. The focus lied on experimentation and theoretical work, and was complemented by studies on natural material and applied mineralogy.
The speakers of the Research Group Wilhelm Heinrich (GFZ) and Rainer Abart (University of Vienna) organized an EMU school on Mineral Reaction Kinetics from 19-23 September 2016 in Vienna and are editors of the EMU Notes in Mineralogy, Volume 16 "Mineral reaction kinetics: microstrutures, textures, chemical and isotopic signatures".
