Demonstration of a diamond anvil cell platform at the Linac Coherent Light Source: capabilities and outlook

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 552-561, May 2026.
A setup for fielding high‐pressure samples contained in diamond anvil cells (DACs) at the LCLS X‐ray free electron laser is described and example powder X‐ray diffraction data are presented. Future prospects for experimental capabilities in DACs enabled by the LCLS, such as short pulse laser interactions and multiple pulse modes, are discussed.A novel ...

Local Structure and Vacancy Distribution in Transition Metal Carbides: Results From High‐Resolution 13C NMR Spectroscopy

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...

Design Rules for Carboborothermic Reduction Synthesis of High Uranium Density UB4–UBC Composites

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Uranium borides are promising candidate fuel forms for use in advanced nuclear reactors due to their high thermal conductivity and potential for dual use as both fuel and burnable absorber. In this work, uranium tetraboride (UB4${\rm UB}_4$) and uranium monoboroncarbide (UBC) composite were synthesized by using industrially scalable ...
