ON THE COVER: Challenges in Plutonium and Actinide Materials Science. (left, background) Bright-field transmission electron microscope (TEM) image showing large, ~35-nm helium bubbles and the associated dislocation structure in a 35-yr-old Pu-Ga alloy annealed at 400°C to coarsen the bubbles. (left, overlay) Hypothetical structure of borosilicate glass primarily formed of chains of borate and silicate polyhedrons. Lithium, sodium, and calcium glass modifiers create nonbridging oxygens in the network and provide charge balance in the vicinity of the plutonium-oxygen polyhedrons. (upper right) Laboratory pouring of Pu-borosilicate glass (courtesy of D. Karraker). (lower right) Experimentally determined, connected binary phase diagram of adjacent actinide elements, illustrating the transition from typical metallic behavior at thorium to a complex structural behavior at plutonium and back to typical metallic behavior at americium and beyond. See the technical theme that begins on p. 667.
