Jamie became “Dr. Weaver” on December 10, 2016. Jamie’s dissertation was titled, “Localized chemistry of 99Tc in simulated low activity waste glass.” Congratulations Jamie!
The first paper reporting our project looking at the Swedish hillfort vitrified material has been published online.
Sjöblom, R., J. Weaver, D. Peeler, J. McCloy, A.A. Kruger, E. Ogenhall, and E. Hjärthner-Holdar, “Vitrified Hillforts As Anthropogenic Analogues For Nuclear Waste Glasses – Project Planning And Initiation,” International Journal of Sustainable Development, 11(6), 897-906 (2016).
Prof. McCloy and Jamie Weaver recently attended the 100th anniversary conference of the Society for Glass Technology (SGT) in Sheffield, UK.
Below are some pictures of Jamie presenting to a packed room of nuclear waste scientists, and to a large auditorium in a joint session of cultural heritage glass scientists and nuclear waste glass corrosion experts. Great job Jamie!
José Marcial was selected and attended the National School on Neutron and X-ray Scattering (NXS), in July/August. From their website:
“The main purpose of the National School on Neutron and X-ray Scattering is to educate graduate students on the utilization of major neutron and x-ray facilities. Lectures, presented by researchers from academia, industry, and national laboratories, will include basic tutorials on the principles of scattering theory and the characteristics of the sources, as well as seminars on the application of scattering methods to a variety of scientific subjects. Students will conduct short experiments at Argonne’s Advanced Photon Source and Oak Ridge’s Spallation Neutron Source and High Flux Isotope Reactor facilities to provide hands-on experience for using neutron and synchrotron sources.”
Saehwa Chong and José Marcial published proceedings from the Waste Management 2016 conference, held in March in Phoenix, Arizona.

Dr. Patil joined our group in April, coming from University of Pardubice, Czech Republic.
Yue Cao, Ke Xu, José Marcial, and Saehwa Chong all passed their preliminary exams for the Materials Science & Engineering Program this semester. Great job!
Our work on studying ancient Swedish hillfort glasses was recently featured in WSU News (https://news.wsu.edu/2016/04/25/ancient-glass-glued-fortification-studied-nuke-waste-solutions/) and this story was picked up by several online news feeds.
The original paper discussed in the press release can be found here (http://ceramics.org/wp-content/bulletin/2016/May16/May-2016-Bulletin-Ensuring-longevity.pdf).
José took 1st place in both microscopy categories this year for this images. Below are the writeups and images. Great job José!
Winner for “Technical Image”
Title: Distribution of elemental species of crystallized Hanford high‐level nuclear waste glass Description: Vitrification of Hanford high‐level nuclear waste glasses requires careful balancing of the composition. High additions of nuclear waste tend to lead to the formation of crystals that lower the corrosion resistance and can lead to leaching of radioactive components. Low additions increase the time required to vitrify the over 55 million gallons of nuclear waste present at the Hanford site. Presented here is a nuclear waste glass that has crystallized upon cooling. The inset images show the distribution of different components in this sample. Of particular interest is boron which is very difficult to measure with most laboratory techniques and is a major component of Hanford waste glasses. This image is the first to demonstrate that boron does not enter the crystalline structure in a significant amount. The atomic concentration scales from cold (blue) to hot (red).
Winner for “Artistic Image”
Title: the elegance of crystallographic texture.
Description: this image is and electron back scatter diffraction image of an inconel superalloy. The colors represent
different crystallographic orientations that distinguish neighboring grains that comprise the alloy and accent the beauty
of the world of engineering. The aim of this material is to improve both ductility and fatigue strength by increasing the
number of striations within the grains (known as annealing twins).
Joseph Osborn won the 2016 WSU Emeritus Society Undergraduate Research Award in the category of Physical Sciences for his poster presentation at SURCA (Showcase for Undergraduate Research & Creative Activities) entitled “Primordial Glass: an Aegis in the Nuclear Age”, recounting attempts to recreate Ancient Hillfort glasses.
