1. Open-Framework Germanates : Synthesis, Structure, and Characterization
Sammanfattning : Novel open-framework germanates and open low-dimensional structures were synthesized and characterized. Their crystal structures were solved by single crystal X-ray diffraction or X-ray powder diffraction combined with other techniques. LÄS MER
2. Inorganic and Metal-Organic Framework Materials : Synthesis and structure characterization
Sammanfattning : Inorganic and metal-organic framework materials possessing accessible and permanent pores are receiving tremendous attention. Among them, zeolites are the most famous class due to their wide applications on petrochemistry and gas separation. LÄS MER
3. Novel framework materials : organically templated silicogermanates and hybrid fluorotitanates
Sammanfattning : Two types of novel framework materials, including six organically templated silicogermanates and five hybrid fluorotitanates, have been synthesized, and their structures have been determined by single crystal X-ray diffraction. Their structures and the interactions between the organic and inorganic species are discussed in some detail. LÄS MER
4. Open-Framework Germanates and Nickel Germanates : Synthesis and Characterization
Sammanfattning : Microporous materials have a wide range of important applications in separation, gas adsorption, ion-exchange and catalysis. Open-framework germanates are a family of microporous compounds and are of particular interest. LÄS MER
5. Detailed structure features from 3D electron diffraction : Heteroatoms, framework disorders, and guest species in zeolites
Sammanfattning : 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. LÄS MER
