THE recent communication in Nature 1 by J. Gibson directing attention to new extra lines in the X-ray powder diffraction pattern of graphite led us to re-examine a number of photographs of purified ...

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 ...

A new technique uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips. “The biggest advantage is that you ...

X-ray diffraction (XRD) is a powerful non-destructive analytical technique used to evaluate crystalline materials and determine their structural properties. As one of the most widely used ...

The Scintag XDS2000 powder diffractometer is configured with a graphite monochromater and IBM compatible workstation running Scintag DMSNT software in Windows NT environment. New cameras installed in ...
