1. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination
Abstract : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.

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

3. 3D Electron Microscopy Methods and Applications : Structures from Atomic Scale to Mesoscale
Abstract : The crystal structure determines the physical properties of a material. The structure can be analysed at different levels, from atomic level, mesoscale level, all the way up to the macroscale level. READ MORE

4. Detailed structure features from 3D electron diffraction : Heteroatoms, framework disorders, and guest species in zeolites
Abstract : 3D electron diffraction (3D ED) has evolved as a powerful method for ab initio structure determination from sub micrometer-sized crystals. It can be used to elucidate the arrangement of atoms in crystalline materials and to provide insights into the laws of nature that govern the properties of matter. READ MORE

5. Characterization of crystalline materials by rotation electron diffraction : Phase identification and structure determination
Abstract : Electron crystallography is powerful for determination of complex structures. The newly-developed 3D electron diffraction (ED) methods make structure determination from nano- and micron-sized crystals much easier than using other methods, for example X-ray diffraction. READ MORE
