1. 1. Exploiting reciprocal space : Electron diffraction, textures and precession

   Författare :Peter Oleynikov; Sven Hovmöller; Xiaodong Zou; Jean-Paul Morniroli; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; electron diffraction; texture patterns; precession electron diffraction; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. LÄS MER

3. 2. 3D Electron crystallography : Real space reconstruction and reciprocal space tomography

   Sammanfattning : Electron crystallography is an important technique for studying micro- and nano-sized materials. It has two important advantages over X-ray crystallography for structural studies: 1) crystals millions of times smaller than those needed for X-ray diffraction can be studied; 2) it is possible to; focus the electrons to form an image.

   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; three-dimensional electron diffraction; metal-organic framework; open-framework germanates; guest molecules; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Knowing the atomic crystal structures of ordered porous solids is essential in understanding their behaviors and properties, developing new applications, and designing new porous materials. Electrons have a much shorter wavelength and much stronger interaction with atoms in a crystal compared with X-ray. LÄS MER
