11. Contributions to Emission, Exposure and Risk Assessment of Nanomaterials
Sammanfattning : In recent years, synthetic nanomaterials have begun to be produced and used in increasingly larger volumes. These materials may cause new or increased risks to the environment, but no harmonized methods for structured assessment of their environmental risks exist. LÄS MER
12. Recovery and reuse of TiO2 and other pigments from paint waste
Sammanfattning : Titanium dioxide (TiO2) has numerous applications in our society, most notably as a white pigment in products such as paint, paper and plastic. Since 2010 there has been a sharp increase in the demand for and price of TiO2. As a result new and innovative ways of TiO2 production are needed. LÄS MER
13. Hydrolytic Synthesis and Physicochemical Properties of TiO2 Nanoparticles: Fundamentals and Applications
Sammanfattning : Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with well-defined size distributions were obtained. LÄS MER
14. Electron Transfer in Ruthenium-Manganese Complexes for Artificial Photosynthesis : Studies in Solution and on Electrode Surfaces
Sammanfattning : In today’s society there is an increasing need for energy, an increase which for the most part is supplied by the use of fossil fuels. Fossil fuel resources are limited and their use has harmful effects on the environment, therefore the development of technologies that produce clean energy sources is very appealing. LÄS MER
15. Computational Investigation of Dye-Sensitized Solar Cells
Sammanfattning : Interfaces between semiconductors and adsorbed molecules form a central area of research in surface science, occurring in many different contexts. One such application is the so-called Dye-Sensitized Solar Cell (DSSC) where the nanostructured dye-semiconductor interface is of special interest, as this is where the most important ultrafast electron transfer process takes place.
