  1. 1. 3D Printing Wood Tissue

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Kajsa Markstedt; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogel; Galactoglucomannan; Crosslinking; Biocomposite; 3D Printing; Wood Tissue; Xylan; Printability; Cellulose Nanofibrils;

    Abstract : Biomass from forests provides society with energy, materials and chemicals, thus contributing to the circular bioeconomy. The majority of biomass is found in the wood tissue of trees. READ MORE

  2. 2. 3D Reconstruction of Porous and Poorly Conductive Soft Materials using FIB-SEM Tomography

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Cecilia Fager; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; insulating material; 3D; interconnectivity; focused ion beam; tomography; polymer film; scanning electron microscopy;

    Abstract : Focused ion beam combined with scanning electron microscope (FIB-SEM) is a powerful tool that can be utilised to reveal the internal microstructure of materials. It basically uses ions to make cross-sections with high precision and electrons to image the cross-section surface with high spatial resolution. READ MORE

  3. 3. Estimation of forest parameters using 3D satellite data

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Henrik Persson; Sveriges lantbruksuniversitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Accurate data about the forest are needed both in climate research and forest management planning. This thesis focuses on using different types of three-dimensional (3D) satellite data sources to accurately estimate forest variables, primarily above-ground biomass (AGB) and tree height (H).

  4. 4. 3D-woven Reinforcement in Composites

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fredrik Stig; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Composites made from three-dimensional (3D) textile preforms can reduce  both the weight and manufacturing cost of advanced composite structures  within e.g. aircraft, naval vessels and blades of wind turbines. READ MORE

  5. 5. Polishability of tool steels : Characterisation of high gloss polished tool steels

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Sabina Rebeggiani; Högskolan i Halmstad.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; tool steels; surface characterisation; polishability; 3D parameters; high gloss polishing; Tool steels;

    Abstract : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.
