Optical Diffraction Studies of Crystalline Structures in Electron Micrographs
Determination of the unit cell of crystalline particles by optical diffraction analysis of electron micrographs may establish the identity and help in approximating the molecular weight of the substances contained in the crystal. This technique may be particularly helpful when isolation and purification of the crystalline material cannot be accomplished.
متن کاملOPTICAL DIFFRACTION STUDIES OF CRYSTALLINE STRUCTURES IN ELECTRON MICROGRAPHS II. Crystalline Inclusions in Mitochondria of Human Hepatocytes
Unit cell dimensions of mitochondrial crystals were determined by optical diffraction analysis of electron micrographs of human liver biopsy specimens . Identical unit cells were found in pathologic material obtained from six patients with Wilson's disease, from one patient with sickle-cell hepatitis, and from two normal subjects . These measurements led to the conclusion that the crystals obse...
متن کاملInvestigation of Nanocrystals Using Tem Micrographs and Electron Diffraction Technique
The aim of this work is to determine mean diameter of polycrystalline samples using Scherrer equation. These represent direct connection between mean diameter and crystal structure and morphology by including the Bragg angle and shape factor. Two samples are investigated, first a nano-sized particles of MgO and second a CVD (Chemical Vacuum Deposition) obtained polycrystalline aluminum film. Fi...
متن کاملX-ray Diffraction Studies on Crystalline Complexes
Complexes of the gene 5 protein with a variety of oligodeoxynucleotides, ranging in length from two to eight and having several different sequences, have been formed and crystallized for x-ray diffraction analysis. The crystallographic parameters of four different unit cells, all of which are based on hexagonal packing arrangements, indicate that the fundamental unit of the complex is composed ...
متن کاملSupercomputer simulation of small angle X-ray scattering, electron micrographs and X-ray diffraction patterns of macromolecular structures
We describe two algorithms used in structural studies of proteins and macromolecular complexes. The first deals with simulation of Small Angle X-ray Scattering patterns. An approximate representation of the Debye formula based on the discretized histogram of pair distances allows the SAXS calculation of large macromolecules modelled by thousands of spheres to be performed in a few minutes of CP...
