Interfacial Dynamics in Radioactive Environments and Materials (IDREAM)

Interfacial Structure & Reactivity

Extend fluid phase dynamics to nucleation, particle growth, and interfacial reactivity in highly alkaline systems of concentrated electrolytes.

  • What controls the interfacial chemical dynamics of aluminum (oxy)hydroxide growth and dissolution?
  • How are the coordination changes of Al3+ ions that underpin nucleation, particle growth, and dissolution of (oxy)hydroxides facilitated or inhibited by the structure and dynamics at metal (oxy)hydroxide/solution interfaces in relevant environments?

Research Goals

EFRC at PNNL

Vision

Master molecular–to–mesoscale chemical and physical phenomena at interfaces in complex environments characterized by extremes in alkalinity and low-water activity, and driven far from equilibrium by ionizing radiation.
