11. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells
Sammanfattning : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. LÄS MER
12. Dissolution of cellulose in aqueous hydroxide base solvents
Sammanfattning : As we move towards a circular bioeconomy, new and advanced materials based on cellulose are constantly developed. Unlike most plastics or metals, cellulose cannot be melted, and therefore dissolution is an important tool for processing of cellulose but also for analytical purposes. LÄS MER
13. Biomolecule Trapping With Stimuli-Responsive Polymer Coated Nanostructures
Sammanfattning : Trapping biomolecules in nanosized gaps is of great interest in novel systems for single molecule analysis and membranes, which filter biomolecules. Current platforms are lacking in full functionality to facilitate biomolecule trapping and transport in their native environment and without covalent tethering to surfaces. LÄS MER
14. Polymer/polymer blends in organic photovoltaic and photodiode devices
Sammanfattning : Organic photovoltaics devices (OPV) have attracted attentions of scientist for their potential as inexpensive, lightweight, flexible and suitable for roll-to-roll production. In recent years, considerable attention has been focused on new acceptor materials, either polymeric or small molecules, to replace the once dominating fullerene derivatives. LÄS MER
15. Porous polymeric materials for chromatography : Synthesis, functionalization and characterization
Sammanfattning : Background: Separation science is heavily reliant on materials to fulfill ever more complicated demands raised by other areas of science, notably the rapidly expanding molecular biosciences and environmental monitoring. The key to successful separations lies in a combination of physical properties and surface chemistry of stationary phases used in liquid chromatographic separation, and this thesis address both aspects of novel separation materials.
