High-pressure diffraction of Prussian blue analogues

We present recent work on high pressure powder diffraction (HPPD) of Prussian blue analogues (PBAs) using X-rays and neutrons up to (and above) 1 GPa of applied pressure. These PBAs are nominally face-centered cubic materials of metals linked by cyanide. Interest in PBAs has been in varied from magnetism, to fundamentals of the structure, and more recently as cathode materials for energy storage. Indeed, incorporation into devices (such as a cathode) requires understanding of response to strain, for which HPPD is one useful tool.
