The diffraction of X-rays by crystals may be applied to a wide range of problems which include the determination of the structure of crystals, the identification of compounds, the measurement of strain, the determination of coefficients of expansion and of densities, the measurement of the size ...
It also describes how X-ray crystallography helps in study of the structure of materials including bio-molecules. It is the text of Sir C V Raman memorial lecture delivered by the author during February 2005 at Mysore.doi:10.1080/02564602.2005.11657912J SHASHIDHARA PRASAD...

In the industrial sector, X-rays are instrumental in ensuring the integrity and safety of materials and structures. X-ray radiography is used to inspect metal components and welded joints for internal flaws, such as cracks, voids, and inclusions, without damaging the parts. This non-destructive ...
X‐ray crystallographyCryo-electron microscopy (cryo-EM) is a structural biological method which is used to determine the 3D structures of biomacromolecules. After years of development, cryo-EM has made great achievements, which has led to a revolution in structural biology. In this paper, the ...
Figure 8 shows a diffraction pattern produced by the scattering of x rays from a crystal. This process is known as x-ray crystallography because of the information it can yield about crystal structure, and it was the type of data Rosalind Franklin supplied to Watson and Crick for DNA. Not ...

Characterization of a crystalline pharmaceutical drug substance frequently involves obtaining a structural solution by single-crystal X-ray crystallography. This crystallographic data set can also be used to calculate a powder diffraction pattern for that particular crystalline...
The time resolution of X-ray crystallography has typically been in the range of seconds or tens of seconds. Now, a new technique uses pulsed synchrotron radiation and Laue X-ray diffraction to take snapshots of protein structural changes... S Borman - 《Chem.eng.news》 被引量: 56发表: 199...
