Presence and Persistence of Uranyl Peroxide Nanoclusters in Contact with Geological Media

Autor: Mark Antonio, L. Soderholm, Katie M. Gunderson, Peter C. Burns, Karrie-Ann Kubatko

Publikováno v: MRS Proceedings. 893

Recently uranyl peroxide nanoclusters containing 24, 28, and 32 uranyl polyhedra were chemically and structurally characterized under alkaline conditions. Such nanoclusters could conceivable form from oxidative alteration of nuclear waste in a geolog
