a) The X-ray scattering of materials is caused by the electron density r, and the scattering amplitude is the summation of scattering wave from an each electron. The scattering intensity is proportional to the square of the amplitude.b) Electron density r within the crystal has a periodicity,...

Electron crystallography is the quantitative use of different information by electron scattering to study perfect crystal structures as well as defects and interfaces. The development of electron crystallography is summarized. Electron crystallography is compared with X-ray crystallography. Examples of recent...
Because of the tiny wavelength of x-rays, they are useful for imaging small structures, such as individual molecules. This research field is known as x-ray crystallography, which was responsible for uncovering the physical structure of DNA, among other achievements. Today it is frequently used to...

Why are X-rays used for crystallography instead of other frequencies of electromagnetic radiation? Which type of electromagnetic radiation has a shorter wavelength than blue light? What type of radiation is used in IR spectroscopy? Which type of electromagnetic radiation has the lowest frequency?...
All the shown intermediates were structurally determined by X-ray crystallography or cryo-electron microscopy (cryo-EM). PDB accession codes are indicated in light grey. Structure representations restricted to the DNA-binding/cleavage domain were generated from the E. coli DNA gyrase structure without...
