Mineral Crystallization, Aggregation, and Dissolution
(Co-sponsored by ENVR and PHYS)
Mineral crystallization, aggregation, and dissolution represent crucial research domains spanning geochemistry, materials science, environmental engineering, and biomedicine. A comprehensive understanding of the mechanisms behind these processes is essential for designing and developing novel materials, as well as predicting and controlling mineral formation in both environmental and industrial contexts. For instance, unraveling the crystallization, aggregation, and dissolution of iron (oxyhydr)oxide minerals in natural environments is of enduring interest due to its impact on regulating global biogeochemical cycles of various elements such as C, O, N, and S. The fast-paced growth of this field brings forth a challenge — the need to establish a fundamental understanding of interactions among ions, molecules, complexes, clusters, and/or nanoparticles in a growth medium, and the resulting response dynamics. This session aims to address this challenge by highlighting contributions related to:
1) dynamic changes of nanomineral reactivity throughout nucleation, crystal growth, aggregation, and dissolution;
2) the influence of additives on mineral crystallization, aggregation, and dissolution;
3) computational modeling and simulation of mineral crystallization, aggregation, and dissolution;
4) in-situ observation of mineral crystallization, aggregation, and dissolution;
5) crystallization pathways in biomineralization;
6) thermodynamic and kinetic parameters controlling mineral formation, alteration, and dissolution.
The objective of this session is to create a platform for interdisciplinary researchers from geology, chemistry, physics, biology, computational chemistry, and materials sciences to share their knowledge and approaches. This collaborative effort aims to enhance our understanding of mineral crystallization, aggregation, and dissolution, providing new insights into biogeochemical processes in nature and facilitating the design of novel functionalized materials.
The topics that would be covered in this session are, but are not limited to:
1) Mineral nucleation and crystal growth
2) Particle-based crystallization
3) Self-assembly of nanominerals
4) in situ observation of the mineral crystallization, aggregation, and dissolution.
5) Thermodynamic modeling and measurements in geochemistry
6) Biomineralization
7) Mineral dissolution
8) Computational modeling and simulation on the mineral crystallization, aggregation, and dissolution.

Reactivity at the Mineral-Water Interface: Validation Through Modeling and Experiments at the Pore Scale
(Co-sponsored by ENVR and ENFL)
Recent developments in experimental and modeling techniques have had a huge impact on geoscience research. High flux neutron and X-ray sources enable in-situ observations of nonequilibrium processes such as phase transformations on flat surfaces and in complex porous matrices. Large scale molecular simulations and highly resolved pore scale simulations give us an unprecedented ability to quantitatively test hypotheses regarding processes at the mineral-water interface. However, the connection between experiments and simulations remains an important challenge for geoscientists. In part, this is due to the large range scales associated with these processes and the heterogeneity of geomaterials.
This session focuses on how the data from experimental and modeling studies can be successfully utilized for testing hypothesis and validating theories. In particular, how experimental observations can validate modeling techniques, indicate novel unconsidered phenomena, and help to understand complex chemical mechanisms occurring on mineral surfaces. We are specifically interested in contributions that incorporate modeling or experiments at the pore scale. Studies that use molecular-scale-derived understanding of mineral and liquid solution properties to fill the knowledge gaps in pore-scale studies are also encouraged. We welcome submissions that combine characterization, experimental, data processing, and modeling methods to explain mineral reactivity in CO2 storage and transformation, contaminant remediation, underground hydrogen storage, and other subsurface geochemical applications.

The Role of Mineral-Water Interfaces in Carbon Mineralization and Critical Mineral Recovery
(Co-sponsored by ENVR)
Carbon mineralization in reactive reservoirs (i.e. basalt, peridotite) is being explored for permanently sequestering CO2 through mineralization. Commercial scale subsurface sequestration requires a Class VI well permit. Acquisitions of a Class VI permit requires reservoirs benchmarked and parameterized by field- and laboratory-derived data, enabling accurate predictions of the fate and transport of the injected CO2. This data includes temperature- and pressure-dependent kinetics of mineral dissolution, secondary mineral crystallization, and secondary mineral identity. Subsurface injection and mineralization of CO2 is additionally being explored as an aid in critical mineral release and recovery. This session is motivated by the need to assess the state of science in understanding the complex and key processes occurring at mineral-water interfaces within the applied context of carbon mineralization and critical mineral recovery. Contributions are invited that highlight the fundamental and applied geochemistry at the mineral-water interface as it relates to mineral dissolution, precipitation, carbon mineralization, and critical mineral recovery, as well as emerging experimental techniques to understand these processes. We encourage submissions that utilize bench scale experiments, molecular simulations, and reactive transport models.
