Patricia Huestis Explains Radiation's Roles in Energy Research

(July  2018)

Congratulations to Patricia Huestis on her latest article in Frontiers in Energy Research. In the article, Huestis explains how radiation in different forms inspires, assists, and drives diverse research. She brings in examples from six centers. She selected each example based on its ability to showcase a radiation-related process.

Wet Aluminum Hydroxide and Oxyhydroxide Particles Release Hydrogen When Irradiated

Insights into metal's radiolytic behavior could ease final processing of nuclear waste

(June  2018)

Vitrifying nuclear waste for final storage is complicated by aluminum. Knowing how aluminum particles behave is vital. New research suggests that upon radiolysis, the bulk properties of humid aluminum particles do not change substantially but hydrogen is formed.

Elias Nakouzi Joins the 2017 Class of Pauling Fellows

(April  2018)

Congratulations to Dr. Elias Nakouzi on receiving one of PNNL's Linus Pauling Distinguished Postdoctoral Fellowships. Known for his wide-ranging research into material formation, Nakouzi studies crystallization, growth aggregation, and assembly. With his colleagues at IDREAM, he is developing the tools needed to visualize and analyze the water-based layers that form where minerals meet liquids.

IDREAM Center Discusses Nuclear Waste with DOE Under Secretary for Science

(March  2018)

Under Secretary Paul Dabbar and Chief of Staff Kristen Ellis toured Pacific Northwest National Laboratory and met with Sue Clark, Director of the IDREAM EFRC, to discuss interfacial chemistry in radioactive wastes.

Alkaline solutions of aluminum and sodium ions form complex gels

Tracking Mechanisms of Crystallization in Real Time

Aluminum's coordination change occurs in extreme environments

(March  2018)

Researchers quantified transient penta-coordinated Al3+ species during the crystallization of gibbsite from hydrous aluminum gels in solutions of concentrated sodium hydroxide. The research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways.
