1. Microangiopathies of the human brain b immunohistochemical studies on extracellular matrix components in arterial vessels and endothelin
Sammanfattning : Microangiopathies may cause ischemic brain lesions and are of fundamental importance in vascular dementia. Risk factors include high age, hypertension, diabetes and Alzheimer's disease. LÄS MER
2. Aqueous graphene dispersions for paper packaging
Sammanfattning : Graphene is widely touted as the thinnest and the most versatile material available. As an atomically thin layer of carbon atoms arranged in a hexagonal configuration, graphene has a combination of technologically important properties, such as thermal and electrical conductivity, mechanical strength, and impermeability to gases.

3. Directed Evolution of Glutathione Transferases with Altered Substrate Selectivity Profiles : A Laboratory Evolution Study Shedding Light on the Multidimensional Nature of Epistasis
Sammanfattning : Directed evolution is generally regarded as a useful approach in protein engineering. By subjecting members of a mutant library to the power of Darwinian evolution, desired protein properties are obtained. Numerous reports have appeared in the literature showing the success of tailoring proteins for various applications by this method. LÄS MER
4. Experimental Studies of Neutron Deficient Nuclei in the A ≈ 110 and A ≈ 170 Mass Regions
Sammanfattning : This doctoral thesis describes several experimental studies on the structures of neutron-deficient nuclei with mass numbers A≈110 and A≈170. The experiments were carried out at the Accelerator Laboratory of the University of Jyväskylä, Finland, using heavy-ion fusion-evaporation reactions induced by beams of energies around 5 megaelectronvolts/nucleon.

5. Functional Materials for Perovskite Solar Cells
Sammanfattning : Energy plays a significant role in our daily lives, but most energy provided by fossil fuels causes serious environmental problems including air pollution, global warming, and ecological damage. In addition, it has been estimated that all of our fossil fuels will run out in 2088 and thus it is highly important to study and apply renewable energy sources. LÄS MER
