26. The Electronic Structure of Organic Molecular Materials : Theoretical and Spectroscopic Investigations
Sammanfattning : In the present thesis the electronic properties of two organic molecules were studied by means of density functional theory (DFT) in connection to their possible applications in organic photovoltaics and molecular spintronics respectively.The first analysed system is the C60 derivative PCBM extensively used in polymer solar cells for the charge separation process.

27. Colloidal Processing and Alignment of Wood-Based Dispersions and Hybrid Functional Foams
Sammanfattning : This thesis presents novel methods and approaches for designing, preparing/fabricating, and characterizing wood-based nanomaterials. It investigates how modifications in structure, process variables, and composition can enhance functional properties. LÄS MER
28. Nanostructured Transition Metal Oxides in Cleantech Application : Gas Sensors, Photocatalysis, Self-cleaning Surfaces Based on TiO2, WO3 and NiO
Sammanfattning : This thesis focuses on the application of nanocrystalline transition metal oxide TiO2, WO3 and NiO thin films in new “green” building technologies. Specifically, their physicochemical properties in photocatalytic, self-cleaning and gas sensing applications are studied. LÄS MER
29. Nanocellulose-based materials: from colloidal assembly to functional films
Sammanfattning : The assembly of nature-based nanomaterials into complex architectures is both a design principle of biological composites, e.g., wood and nacre with outstanding properties and a promising route for developing functional macroscopic materials. LÄS MER
30. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability
Sammanfattning : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.
