IN an earlier article in Nature 1 I reported some results of a study of the high-temperature transformation of diamond to graphite. In this work diamond powder of 0–1μ particle size was used. Samples ...

Non-ambient diffraction is a powerful tool for identifying the effects of temperature, humidity, pressure, or atmosphere on a sample. Materials exposed to non-ambient environments tend to have ...

Specimen mounting in x-ray powder diffraction affects peak positions and intensities. The specimen-mount procedure is one of the many actions an investigator employs that could dramatically affect ...
