Title: Cubic to Tetragonal Phase Transformation in Cold-Compressed Pd Nanocubes

Journal Article · · Nano Lett.8:972-975,2008
OSTI ID:959354

Pd nanocubes with an average side length of {approx}10 nm were compressed up to 24.8 GPa in a diamond-anvil cell (DAC). In situ synchrotron X-ray diffraction was used to monitor structural changes, and a face-centered cubic (fcc) to face-centered tetragonal (fct) distortion was observed for the first time. This novel discovery not only provides new insights into the pressure-induced behavior of faceted nanocrystals of palladium and other noble metals but also gives guidance for finding new phases in close-packed metals.
