1. A Photogrammetric Workflow to Produce 3D-Models of Geological Samples
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : Photogrammetry and Structure-from-Motion (S-f-M) is a low-cost method of producing digital 3D models of rock samples that can be used for many different research and educational purposes. A 3D model of a delicate rock sample would enable the preservation of the sample and reduce the need of physical manipulation. READ MORE

2. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system
University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE

3. Laser Scattering for Fast Characterization of Cellulose Filaments
University essay from KTH/Fiber- och polymerteknologiAbstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.
