1. Iron, Manganese and Iridium Complexes From Models of RNR and Catalase to Water Oxidation
Sammanfattning : The focus of this thesis has been synthesise and study metal complexes that mimic the structure and function of the active site in two particular metalloenzymes, ribonucleotide reductase (RNR) and manganese catalase (MnCAT). These two metalloenzymes both have two transition metals ions in the cofactor: two manganese ions in MnCAT and either two iron, iron-manganese or two manganese ions in RNR. LÄS MER
2. Ribosomal translocation in real time : Method development to Applications
Sammanfattning : Translational elongation is the process in which the ribosome adds one amino acid at a time to the nascent peptide chain. As the ribosome elongates the peptide chain by 14 - 20 amino acids per second and performs hundreds of such cycles per protein, ‘elongation’ is one of the most crucial steps in translation. LÄS MER
3. Pharmacological stimulation of endothelial function and long-term impact of hypertension in man
Sammanfattning : Background: Ischemic heart disease is a major cause of death globally. Rupture of a coronary atherosclerotic plaque with occluding thrombus formation is the main cause of myocardial ischemia and infarction. LÄS MER
4. Insight into Catalytic Intermediates Relevant for Water Splitting
Sammanfattning : Catalysis is an important part of chemistry. This is also reflected in the chemical industry where 85-90 % of all products are made catalytically. Also nature employs catalysts, i.e. LÄS MER
5. Improved methods for enrichment of organic ultra trace components for analysis by gas chromatography
Sammanfattning : This thesis describes some new methods for analysis oforganic trace components from air and water by gaschromatography. The work is particularly focused on thedevelopment of new technologies for analyte enrichment, usingsorbent-based concepts. Short lengths of open tubular columnswere examined for their potential use as denuders. LÄS MER
