X-ray diffraction computed tomography is an experimental technique that combines X-ray diffraction with the computed tomography data acquisition approach. X-ray diffraction (XRD) computed tomography (CT) was first introduced in 1987 by Harding et al. [ 1 ] using a laboratory diffractometer and a monochromatic X-ray pencil beam .

X-ray diffractometer instruments can be used for a variety of purposes including imaging crystal structures, phase determination, and identifying unfamiliar substances for use in crystallography, inspection, and pharmaceutical research for drug efficacy. [2] A novel use of x-ray diffraction involves studying the surface of Mars to determine if ...
X-ray diffraction (XRD) is still the most used method for structural analysis of chemical compounds. Yet, with increasing detail on the relation of K β {\displaystyle K_{\beta }} -line spectra and the surrounding chemical environment of the ionized metal atom, measurements of the so-called valence-to-core (V2C) energy region become ...
When introduced in 1973, the original Miniflex was about one-tenth the size, and dramatically less expensive, than conventional X-ray diffraction equipment of the period. The original instrument, and its successor that was introduced in 1976, employed a horizontal goniometer with data output provided by an internal strip chart recorder .
49-key manuals: 1 on combo organs, 2 on electronic organs The Philicorda was an electronic organ first produced in the 1960s by Philips . It was Philips' first entry into musical instruments and targeted the home market.

A year later, X-ray diffraction was further applied to visualize the three-dimensional structure of an unstained human chromosome. [20] X-ray microscopy has thus shown its great ability to circumvent the diffractive limit of classic light microscopes; however, further enhancement of the resolution is limited by detector pixels, optical ...
