Precursor gels and nanocomposite materials have been characterized using powder X-ray diffraction and transmission electron microscopy.
Hubbard (1971-1988) Single crystal and powder x-ray diffraction methods, software, standard reference materials, and reference patterns collection and evaluation.
Crystal structure determinations using powder X-ray diffraction data are the key to clarify the structural changes responsible for observed symmetry changes and to pinpoint the phase-transition mechanism(s), not only for natrolite but also for other framework silicate minerals.
Powder X-ray diffraction (Rigaku DMAX 2200, Rigaku/USA, MA) and microscopic examinations by scanning electron microscopy (JEOL JSM-5300, JEOL USA Inc.
TransForm's scientists were able to create Form III acetaminophen from a liquid state, and develop a structural model of this elusive third form on the basis of powder X-ray diffraction data and prior computer predictions.
Since powder x-ray diffraction patterns are critical for phase identification, patterns of the new phases were also prepared and were included in the Powder Diffraction File (PDF (1)).
