1. Quantum Chemical Modeling of Dye-Sensitized Titanium Dioxide : Ruthenium Polypyridyl and Perylene Dyes, TiO2 Nanoparticles, and Their Interfaces
Sammanfattning : Quantum chemical calculations have been used to model dye-sensitized nanostructured titanium dioxide systems that can be used in solar cells for solar energy to electricity conversion. Structural, electronic and spectral properties of isolated dyes and both bare and dye-sensitized TiO2 have been calculated with density functional theory, providing detailed information about both the separate parts and the dye-TiO2 interface.

2. Relating the Bulk and Interface Structure of Hyaluronan to Physical Properties of Future Biomaterials
Sammanfattning : This dissertation describes a structural investigation of hyaluronan (HA) with neutron scattering techniques. HA is a natural biopolymer and one of the major components of the extracellular matrix, synovial fluid, and vitreous humor. LÄS MER
3. Efficient Energy Harvesting Interface for Implantable Biosensors
Sammanfattning : Energy harvesting is identified as a promising alternative solution for powering implantable biosensors. It can completely replace the batteries, which are introducing many limitations, and it enables the development of self-powered implantable biosensors. LÄS MER
4. Detection and removal of traps at the SiO2/SiC interface
Sammanfattning : The interface between silicon dioxide (SiO2) and silicon carbide (SiC) is at the heart of the SiC metal-oxide-semiconductor field-effect (MOSFET) transistor. The technology to produce a high quality SiO2/SiC interface does not exist today, hampering further development of the SiC MOSFET. LÄS MER
5. Ge/high-k Gates for Monolithic 3D Integration
Sammanfattning : Continuous scaling of transistor dimensions has been in the heart of semiconductorindustry for many years. Recently the scaling has been enabled by various performance boosters which resulted in increased processing complexity and cost, forcing the chip manufacturers to look for some alternative solutions.
