8 X - ray diffraction : the contributions of Max von Laue , W . H . and W . L . Bragg and

The experimental technique which has been of the greatest importance in revealing the structure of crystals is undoubtedly X-ray diffraction. The story of the discovery of X-ray diffraction in crystals by Laue,∗ Friedrich and Knipping in Munich in 1912 and the development of the technique by W. H. Bragg∗ andW. L. Bragg∗ in Leeds and Cambridge in the years preceding the First World War is well k...

Minerals chemistry and geothermobarometry of Dourbeh and Nari intusive bodies of W Urumieyeh, NW Iran

The studied bodies are located in the west of Urumieyeh Lake and northeast of Oshnavieyeh, in the Sanandaj-Sirjan structural zone. Compositionaly, these bodies are formed from gabbro-diorite (Dourbeh) and granite (Nari). Gabbrodiorite rocks are composed of plagioclase (andesine to bytownite), amphibole (calcic group and magnesio-hornblende-tschermakite-hornblende type) and pyroxene (augite) as ...

Atomic resolution structure of Erwinia chrysanthemi L-asparaginase.

An X-ray structure of L-asparaginase from Erwinia chrysanthemi (ErA) has been refined at 1 A resolution to an R factor of below 0.1, using data collected on a synchrotron source. With four molecules of the enzyme consisting of 327 amino acids each, this crystal contains one of the largest asymmetric units of a protein refined to date at atomic resolution. Previously, structures of ErA and of re...
