   Sammanfattning : Alzheimer’s disease(s) comprises one of the most common and costly neurodegenerative diseases. With a larger population and an increasing life expectancy, amyloid diseases (with age as one of the most prominent risk factors) will generate an even larger burden on healthcare. LÄS MER

4. 13. Crystalline Porous Materials Inspired by Metallodrugs

   Författare :Erik Svensson Grape; A. Ken Inge; Tomislav Friščić; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal-organic frameworks; material synthesis; pharmaceuticals; porous materials; crystallography; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Inspiration for developing robust porous materials from sustainable reagents was acquired by determining the crystal structures of bismuth subsalicylate and bibrocathol, two long-used and commonly available bismuth-based pharmaceuticals. From these insights, a number of coordination polymers and metal-organic frameworks (MOFs) were developed, facilitating the synthesis of robust porous materials from sustainably sourced reagents.
