Precession Electron Diffraction for the structure solution of unknown crystalline phases

following the discovery of x-rays by roentgen, W. H. bragg and W. l. bragg used these waves to perform diffraction experiments on crystals and to determine the atomic positions within their ordered structures. X-ray crystallography has been hugely successful in elucidating the structures of minerals, metals and intermetallics, of biological molecules from small molecules to proteins and the dna double helix. Later, neutron diffraction came in support of x-rays for detection of light elements or for distinguishing elements with similar atomic numbers. The importance of techniques to determine structure can be understood from the fact that knowledge of their structure is paramount to the understanding (and enhancement) of the properties of materials. Here we show the power of electron diffraction for structure solution in the case of nano-scale materials. Full text
