Peter C. Burns has focused most of his research over the
past decade on the solid state chemistry, mineralogy, and environmental
chemistry of uranium, as well as the transuranic elements neptunium and
plutonium.
In 2005 the Burns research group published the first of a family of
novel uranyl peroxide hydroxide spherical nanoclusters. To date, we
have reported the synthesis and structures of nanoclusters containing
24, 28, 32, 40 and 50 uranium atoms. Additional papers will be
forthcoming that report U16, U20 (multiple topologies), U24 (open),
U36, U44 and U60. We will also be completing a "roadmap" for the
synthesis of specific members of this complex family of actinide
nano-scale clusters.
The Burns group has published extensively in uranium mineralogy, and
have reported the crystal structures of dozens of uranyl minerals
including autunite, bijvoetite, vandendriesscheite, wolsendorfite,
boltwoodite, compreignacite, masuyite, haweeite, weeksite, fontanite,
billietite, richetite, zippeite, and studtite.
The structure of studtite, reported by Burns and Kubatko (2003) is the
first structure of a peroxide mineral, and the only one published to
date. As reported by Kubatko et al. (2003) in Science, studtite forms
in nature where radioactivity causes the formation of peroxide in
water. Studtite was the first structure found that involved shared
edges between any uranyl peroxide polyhedra, and the Burns group later
developed a complex group of nano-structured uranium materials based
upon this linkage.
The Burns group has examined the impacts of uranium mineralogy on the release of radionuclides from nuclear waste in a geological repository, such as Yucca Mountain. Much of the emphasis has been on neptunium, as it has a long half-life and is potentially mobile in the environment.
Burns has published extensively on borate mineralogy, copper minerals,
and a variety of exotic new minerals. He has published structural
hierarchies for borate minerals, sulfate minerals, inorganic uranium
compounds, and inorganic neptunium compounds.
