  2. 1. Multimodal Imaging of Anisotropic Hierarchical Materials

    Author : Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomaterials; Hierarchical Materials; Multimodal Imaging; Birefringence; X-Ray Scattering;

    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

  4. 2. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites

    Author : Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Lyotropic liquid crystals; SAXS; Hierarchical materials.; 3D printing; Rheology; Microfluidics; Birefringence microscopy;

    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

  5. 3. Optical Investigations of Chiral Liquid Crystals

    Author : Anders Dahlgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antiferroelectric; de Vries theory; ferroelectric; optical activity; chiral; dielectric tensor; unwinding; liquid crystal; helicoidal; selective reflection;

    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

  6. 4. Nanostructured materials isolated from bio-residues, and their characterization

    Author : Martha Herrera Rodríguez; Henrikki Liimatainen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    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

  7. 5. Electro-Optical Na0.5K0.5NbO3 Films
