Summary of Activities/Interests

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 has 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.

Notre Dame Researchers Work to Improve Nuclear Waste Recycling

June 21, 2017

Researchers within the Center for Sustainable Energy at Notre Dame are thinking creatively about problems surrounding nuclear materials as they search for solutions to reduce waste, decrease the cost of nuclear energy production, and increase efficiency and safety of the entire process.

Searching for Uranium in the Copper State

June 16, 2017

In retrospect, it seems a little funny that three of Dr. Amy Hixon’s graduate students travelled to the Copper State to look for uranium. But as it turns out, there is quite a bit of uranium in Arizona, and these three students have found it where it shouldn’t be. With the help of the GLOBES program and the John J. Reilly Center, Teresa Baumer, Nicole Moore, and Meena Said have analyzed soil samples from the Navajo Nation to determine whether the soil was contaminated with uranium.

Are Uranium Clusters the Key to Cleaner Nuclear Energy?

January 31, 2017

“Those ones are obviously part of our Christmas celebration. They also participate in our Thanksgiving display and our Easter display. They get reworked into every display.” Professor Peter Burns, who is wearing a yellow vest and has the demeanor of a warm-hearted jokester, points to a collection of colorful polyhedrons surrounding a miniature Christmas tree on display outside his lab in Stinson-Remick Hall at the University of Notre Dame.
