The Philicorda came out of the Philips Natuurkundig Laboratorium in Eindhoven, under Tom Dissevelt and Dick Raaijmakers, who worked on electronic music and electronic musical instruments; it was here that the prototype of the AG7400 organ was produced.
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 ...
X-ray diffraction computed tomography, often abbreviated as XRD-CT, typically refers to the technique invented by Harding et al. [1] which assumes that the acquired data are powder diffraction data. For this reason, it has also been mentioned as powder diffraction computed tomography [ 7 ] and diffraction scattering computed tomography (DSCT ...
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering , when there is no change in the energy of the waves.
XRD may refer to: X-ray diffraction , used to study the structure, composition, and physical properties of materials Extensible Resource Descriptor , an XML format for discovery of metadata about a web resource
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 ...
Fish bone pierced in the upper esophagus. Right image without contrast medium, left image during swallowing with contrast medium. To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body.
The detector end of a simple x-ray diffractometer with an area detector. The direction of the X-rays is indicated with the red arrow. A typical diffractometer consists of a source of radiation, a monochromator to choose the wavelength, slits to adjust the shape of the beam, a sample and a detector.
