1. Synthesis of Biomimetic Systems for Proton and Electron Transfer Reactions in the Ground and Excited State
Sammanfattning : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. LÄS MER
2. 5-Aminolevulinic acid and derivatives thereof : properties, lipid permeability and enzymatic reactions
Sammanfattning : 5-aminolevulinic acid (5-ALA) and derivatives thereof are widely usedprodrugs in treatment of pre-malignant skin diseases of the cancer treatmentmethod photodynamic therapy (PDT). The target molecule in 5-ALAPDTis protoporphyrin IX (PpIX), which is synthesized endogenously from5-ALA via the heme pathway in the cell. LÄS MER
3. Transition metal and alloy catalysts in the light of computational materials modelling
Sammanfattning : This thesis is built around two pillars. One is heterogeneous catalysis in the broader context of green chemistry. The focus here is on identifying catalytically active materials suitable for the valorization of renewable feedstocks. LÄS MER
4. Understanding the Structure and Reaction of Single Molecules on Metal surfaces from First Principles
Sammanfattning : The study of surface adsorption and reaction is not only interesting from a scientific point of view, but also important in many application fields such as energy, environment, catalysis, corrosion, electronic device, and sensor. Theoretical calculations are essential in these studies. LÄS MER
5. A theoretical study of 5-Aminolevulinic acid and its esters : properties and lipid permeability
Sammanfattning : 5-aminolevulinic acid (5ALA) is a widely used prodrug in Photodynamic therapy (PDT). The target molecule in 5ALA-PDT is Protoporphyrin IX (PpIX), which is synthesized endogenously via the heme pathway in the cell. LÄS MER
