High Temperature X-Ray Diffraction (HT-XRD) is a powerful means of performing in situ experiments and provides the opportunity to observe the behavior of materials under the influence of variables such as temperature, pressure and chemical potential

Our works shows that the americium pyrochlore (241)Am(2)Zr(2)O(7) undergoes a phase transition to a defect-fluorite structure along with an unusual volume contraction when subjected to internal radiation from alpha-emitting actinides. Disorder relaxa

The 241 Am 2 Zr 2 O 7 phase undergoes a structural transition from pyrochlore to defect fluorite driven by alpha self-irradiation. In an effort to better understand the underlying phenomena of this order-disorder transition, powder X-ray diffraction

A new hermetic sample holder to be used with radioactive or air- and moisture-sensitive samples has been developed; it has been designed to fit most of the commercial Siemens/Bruker diffractometers (e.g.D5000 and D8 series). Thanks to the design of t

The polycrystalline americium pyrochlore Am 2 Zr 2 O 7 was recently synthesized from 241 AmO 2 and ZrO 2 powders and its structure was investigated by X-ray powder pattern fitting. A Rietveld analysis was performed using the computer program JANA 200
