1. Multimodal Imaging of Anisotropic Hierarchical Materials
Abstract : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. READ MORE

2. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites
Abstract : Controlling the micro and nanostructure of materials is highly beneficial in order to tailor their physical properties. Extrusion-based 3D printing is a promising tool to produce hierarchical structures with controlled architecture. READ MORE

3. Optical Investigations of Chiral Liquid Crystals
Abstract : Optical investigations of course involve experimental work, but a theoretical basis is also needed. The first chapter can hopefully can give the non-expert an insight into the science of liquid crystals. Liquid crystals are optically birefringent, and a review of the phenomenon of birefringence follows in chapter 2. READ MORE

4. Nanostructured materials isolated from bio-residues, and their characterization
Abstract : The use of natural components in nanocomposites has continuously increased, due to environmental problems that are growing day by day. The use of bio-residues from forest industries to develop new materials will not only alleviate ecological problems but also affect the economy of forest industries positively. READ MORE
