6. Molecular oxygen and hydrogen peroxide as mild oxidants in catalytic oxidations : Applications to palladium and osmium catalysis
Sammanfattning : In this thesis the use of molecular oxygen and hydrogen peroxide as mild oxidants in transition metal-catalyzed oxidations of organic substrates is discussed. The thesis is divided into three parts.In the first part the use of heteropolyacids as robust oxygen-activating agents for aerobic reoxidation of zerovalent palladium is described. LÄS MER
7. The interaction of dissolved hydrogen with α-radiolytic oxidants during nuclear fuel dissolution
Sammanfattning : Used nuclear fuel contains radiotoxic elements that will need to be kept isolated from the biosphere over a time period of 100 000 years. The KBS-3 geological storage concept aims to prevent the migration of radionuclides into the environment by different engineered barriers. LÄS MER

Sammanfattning : .... LÄS MER
9. Effects of Antioxidants and Pro-oxidants on Oxidative Stress and DNA Damage using the Comet Assay : Studies on Blood Cells from Type 2 Diabetes Subjects and Mouse Lymphoma Cells
Sammanfattning : Diet and oral supplements comprise two distinct sources of antioxidants known to prevent oxidative stress. Beneficial effects from antioxidants have been seen for patients at risk for type 2 diabetes.The aim of this thesis was to evaluate the positive effects of antioxidants against oxidative stress and DNA damage in type 2 diabetes subjects.

10. Making Radical Cations Live Longer
Sammanfattning : The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. LÄS MER
