  4. 2. Structure Determination and Prediction of Zeolites : A Combined Study by Electron Diffraction, Powder X-Ray Diffraction and Database Mining

    Author : Peng Guo; Xiaodong Zou; Christine Kirschhock; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zeolites; rotation electron diffraction; structure determination; structure prediction; strong reflections approach; Inorganic Chemistry; oorganisk kemi;

    Abstract : 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. READ MORE

  7. 5. Pharmaceutical binders and their function in directly compressed tablets : Mechanistic studies on the effect of dry binders on mechanical strength, pore structure and disintegration of tablets

    Author : Sofia Mattsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Compaction; tablet; binder; pore structure; disintegration; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Abstract : In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. READ MORE
