Geochemistry Division Medal Symposium
Join us in congratulating Prof. Vicki Grassian for her selection as the 2023 Geochemistry Division Medalist! Prof. Grassian was selected for her original and creative contributions in understanding the chemistry and global impacts of mineral dust aerosol and nanoscale oxides. In addition to her outstanding knowledge production, Prof. Grassian has stellar contributions to diversity, leadership and service to the geochemistry community, and mentorship of students, postdocs and junior scientists.
Prof. Grassian will be awarded the GEOC Medal in a ceremony at the Spring ACS National Meeting & Exposition in Indianapolis, IN. We will host a symposium in her honor featuring work that honors her many contributions in the areas of atmospheric chemistry, mineral/water interface chemistry, environmental chemistry, mineral dust aerosol and nanoscale oxides.
Fire-affected cycling of carbon and nutrients from molecular to global scales
Fire is a major force in the Earth system that influences global ecosystems patterns and processes. Fire can significantly affect the global carbon and nutrient cycles through not only immediate combustion of plant biomass and litter, but also legacy impacts on ecosystem structure and function. Understanding the spatial patterns and temporal changes of these elemental cycling processes is critical for predicting the trajectories of ecosystem recovery from fire and modeling of fire-ecosystem interactions. This session invites contributions that bring together multidisciplinary insights to better understand how fire affects the physical, chemical, and biological characteristics of ecosystems and their interplay in the post-fire cycling dynamics of carbon and nutrients. Topics include, but are not limited to:
1) characteristics and changes in soil or water chemistry, microbial community, and vegetation in fire impacted ecosystems,
2) laboratory and field studies investigating the transport, transformation, and fate of burning residues (i.e., charcoal and ash),
3) dynamics of below- and above-ground interactions and impacts on carbon and nutrient cycling,
4) novel analytical tools and modeling approaches that improve our understanding of the fire-affected biogeochemical cycling of carbon and nutrients.

Geochemistry for CO2 Capture, Conversion, and Sequestration
It is widely accepted that accumulation of anthropogenic carbon dioxide (CO2) in the atmosphere has caused global warming. The most feasible long-term strategy to avoid the most critical consequences is to capture and sequester CO2 in geological systems. Systematic integration of knowledge across wide spatial and temporal scales of the physicochemical interactions between geologic media and carbon-containing fluids is needed for a successful application. This symposium focuses on creating a platform for cross-disciplinary discussion to bridge the gap between a fundamental understanding of CO2-related geochemical processes and practical applications for the development of the materials and technologies for CO2 sequestration.
We are seeking abstracts on topics including but not limited to:
• Capture, conversion, and sequestration of CO2 using geo- and geo-inspired materials
• Geological CO2 sequestration by mineral carbonation, solubility, and physical trapping
• Enhanced weathering and origins in silicate and carbonate weathering driven by CO2
• Effect of confinement on CO2-containing fluids
• Multiscale modeling of the kinetics and dynamics of carbon-related reactions
• Direct air capture via mineralization
Theoretical, experimental, and field investigations are welcome, as well as research of new material development and techniques for lab- or field-scale applications.

Aquatic Redox Chemistry
Redox reactions play critical roles in determining the quality, chemistry, and biology of natural and engineered aquatic systems. In this broad and inclusive session, we invite contributions on recent developments that explore all aspects of aquatic redox chemistry.

Interfacial Reactivity of Nanoconfined Surfaces
(Co-sponsored by ENVR, COLL, CEI)
Nanoconfinement by interfaces is common in natural systems (soils, sedimentary rocks, and the atmosphere) and in industrial applications (nanocatalysis, water filtration). Nanoconfined systems are characterized by high surface-to-water ratios, overlapping electrical double layers from opposing surfaces, and sometimes by interfacial terminations that include gasses or supercritical fluids. Nanoconfined water is highly ordered and rotationally restricted due to interactions with solid surfaces, leading to relatively low dielectric response. The structure of nanoconfined water impacts mass transport and hydration structures of dissolved and surface-bound species. Because of the distinct properties of nanoconfined water, energetics and reaction pathways at nanoconfined surfaces are non-trivial and distinct from bulk (non-confined) solid-water interfaces. Nanoconfinement effects on interfacial chemistry are critical to separation science, energy generation, carbon storage, nuclear waste disposal, and climate modeling; however, detailed fundamental explanations for the unique reactivity of nanoconfined surfaces remain elusive.
We invite contributions on solid-water interfacial chemistry under nanoconfinement. A mechanistic and conceptual understanding of the key factors controlling reactivity in nanoconfined aqueous solutions requires an integrated approach, and both experimental and computational studies are encouraged. The topics to be covered in this session include, but are not limited to:
• properties of water under nanoconfinement
• interfacial reactivity at nanoconfined surfaces and in nanopores
• mass transport in nanopores and nano-scale water films
• nanoconfinement effects on electron transfer
• nanoconfinement phenomena that can be traced to the field-scale
• dissolution, nucleation, and crystal growth under nanoconfinement
• nanoconfinement effects on thermodynamics and kinetics
• novel experimental and computational methods for studying nanoconfined surfaces

Undergraduate Research in Geochemistry
This session will highlight research projects in geochemistry from undergraduate students, including those who have recently graduated. This session is intended to provide recognition to undergraduate students in geochemistry, encourage networking, identify opportunities for graduate research, and help develop the careers of future chemists. A workshop/networking event for the students will also be included. Students are also encouraged to attend the divisional mixer for additional networking opportunities.

Environmental remediation through microbial and chemical pathways
The transport and transformation of environmental pollutants are highly influenced by natural processes that are either chemical or microbial. Understanding the complex interactions of these chemical and microbial processes assist in designing and optimizing the remediation tactics. This session is aimed to gather the experts who are addressing recent advances in microbial and chemical processes affecting the fate, transport, and remediation of organic and inorganic subsurface pollutants. We invite the experimental, modeling, and remedial contributions to understand microbial metabolism, chemical processes, and transport of pollutant in the natural systems and their state-of-the-art applications for onsite, although we do not put a limit only to natural environment. The research contributions describing the role of mixed microbial communities in biotransformation and their mechanism of pollutant detoxification are invited. We also encourage the submissions that address the emerging applications of nanotechnology for environmental pollution prevention, contaminant treatment, and hazardous waste site cleanup.
The topics that would be covered in this session are, but are not limited to:
• Understanding the microbial and chemical interactions with the inorganic and organic contaminants
in environment, and their influential role in remediation.
• The in-situ and ex-situ remediation for decontamination of metals and organic contaminants from
soil and water phases.
• Biogeochemical interactions of organic contaminants in natural environment.
• Interactions of geochemically important elements/contaminants (C, N, Fe, Mn, Hg, U, As and S)
• Application of these processes to develop remedial technologies for decontamination of inorganic and organic contaminants at the contaminated sites.
• Emerging molecular techniques for identification of microbial processes, interactions, and their networks in geogenic processes.
• Microbial communities, their role and mechanism of contaminant biotransformation in soil, water.
• Nano- and micro- based materials, such as adsorption, membranes, extraction, and photocatalysis for environmental remediation.
• Transformation of wastes into commodity material for economic viability.
