1. Electronic and Molecular Surface Structures of Dye-Sensitized TiO2 Interfaces
Sammanfattning : The dye-sensitized solar cell is a promising solar cell technology. In these systems the key process for light to electricity conversion is molecular in nature and is initiated in dye molecules adsorbed at a semiconducting surface. LÄS MER
2. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces
Sammanfattning : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. LÄS MER
3. The effect of surface steps and oxides on the catalytic activity on model Pd and Rh catalysts
Sammanfattning : A catalyst is a substance that can speed up the rate of a chemical reaction without itself being consumed. Catalysts are crucial for chemical production industries, where about 90% of all chemicals are produced using catalysts. LÄS MER
4. Synchrotron Radiation Studies of Molecular Building Blocks for Functional Materials
Sammanfattning : The research on new materials is a primary driving force for progress in human society. One of the most significant research topic nowadays is the development of new functional materials for technological applications, like perovskite implemented in solar cells, and graphene as a representative for the new 2D materials family.

5. Molecular filtration : the study of adsorbents
Sammanfattning : Adsorbent materials for gas purification have been studied and developed for application in many areas. It is known that a single adsorbent may not adequately control multiple contaminants. Therefore, the development of adsorbent materials has accelerated over the past two decades, and is today an area attracting a lot of attention. LÄS MER
