   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zeolites; rotation electron diffraction; structure determination; structure prediction; strong reflections approach; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Zeolites are crystalline microporous aluminosilicates with well-defined cavities or channels of molecular dimensions. They are widely used for applications such as gas adsorption, gas storage, ion exchange and catalysis. The size of the pore opening allows zeolites to be categorized into small, medium, large and extra-large pore zeolites. LÄS MER
