11. Catalytic valorization of lignocellulose : Direct and sidestream upgrading approaches
Sammanfattning : This work aims to explore different approaches for the valorization of lignocellulosic biomass. In this regard, two different strategies are presented: the catalytic upgrading of lignocellulose derivatives from industrial streams, such as pyrolytic oil and kraft lignin, and the direct catalytic fractionation of woody biomass.

12. Electron Donor Systems in Natural and Artificial Photosynthesis
Sammanfattning : Photosynthesis is the process by which light energy is converted into chemical products, in photoautotrophic bacteria, algae and plants. The principal idea is the production of reducing agents by photo-induced oxidation of a sacrificial electron donor. LÄS MER
13. In vivo functions of mammalian glutaredoxin 2
Sammanfattning : Oxygen is essential for all respirating life forms. However, the use of molecular oxygen as terminal electron acceptor of the respiratory electron chain leads to the generation of reactive oxygen species (ROS) as product of incomplete oxygen reduction. To different extends, ROS can react with and damage DNA, lipids and proteins. LÄS MER
14. Modelling long-term redox processes and oxygen scavenging in fractured crystalline rocks
Sammanfattning : Under de senaste decennierna har i många länder, inkluderat Sverige, långt gångna planer utvecklats för ett djupförvar av högaktivt kärnavfall. Som en del i det svenska förvarskonceptet skall avfallet inneslutas i kopparkapslar som omslutes av återfyllnadsmaterial med mycket låg genomsläpplighet av vatten. LÄS MER
15. Adsorption, desorption, and redox reactions at iron oxide nanoparticle surfaces
Sammanfattning : Iron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport.
