1. 1. Iron Carbonyl Mediated Parallel Synthesis

   Författare :Henrik Gradén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dienyl; scavenger; solid phase; galectin inhibitor; oseltamivir; iron carbonyl complex; polymer bound reagent; cation; linker; parallel synthesis; active ester;

   Sammanfattning : This thesis describes the examination and development of cationic iron carbonyl complexes for use in parallel synthesis both in solution phase and on solid phase. A solution phase methodology for carbon-carbon and carbon-heteroatom formation, utilizing polymer bound reagents and scavengers and amenable for automation has been successfully developed. LÄS MER

3. 2. Diffusion of Radionuclides in Bentonite Clay : Laboratory and in sity Studies

   Författare :Mats Jansson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; Chemistry; Kemi;

   Sammanfattning : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. LÄS MER

4. 3. Non-covalent Modification of Graphene and MoS2 Synthesis and Characterization of Charged Molecules and Two-Dimensional Materials

   Författare :Steffen Brülls; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sensors.; molybdenum disulfide; intermolecular interactions; charged π-conjugated systems; doping; non-covalent interactions; functionalization; cation; Graphene; anion;

   Sammanfattning : Graphene is a material of superlatives. It has unique properties, which are explored in various areas of interdisciplinary research. Graphene can improve the properties of other materials or even give them new functions and is therefore a suitable candidate for different sensor applications. LÄS MER

7. 5. Using de novo design proteins to explore tyrosine radicals and cation-π interactions

   Författare :Bruce W. Berry; Cecilia Tommos; Anders Hofer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tyrosine; radicals; cation-pi interactions; de novo designed proteins; biochemistry; biophysics; Biochemistry; biokemi;

   Sammanfattning : Redox cofactors and amino-acid free radicals play important roles in biology. Although many of the same cofactors and amino acids that form these radicals are found across a broad range of biological systems, identical cofactors can have different reduction potentials. The local environment plays a role in defining these redox potentials.
