Understanding the impact of interfacial radiolysis on the dynamics of mineral nanoparticle interactions


EMSL Project ID
61041

Abstract

The primary objective of this proposal is to advance our understanding of the dynamic processes that govern the aggregation of environmentally relevant nanoparticles, such as boehmite and gibbsite, within varying solution chemistry environments. This research will advance the effective management of legacy nuclear waste and reduce risk associated with its release into the environment. Our approach entails the comprehensive utilization of experimental, theoretical, and simulation methods to investigate the influence of solution chemistry on the aggregation behavior of nanoparticles associated with Hanford tank waste. We also aim to unravel the intricate interdependencies among crystal structure, particle morphology, solution chemistry, and interparticle forces in this context.
