  1. 1. Audhumbla and Heidrun beyond gods and mead : Species selection for production of leather in Late Iron Age Scandinavia

    University essay from Uppsala universitet/Arkeologi

    Author : Stella Carlson; [2023]
    Keywords : Leather; tanning; ZooMS; Vendel Period; Viking Age; Iron Age; craft; Valsgärde; Läder; garvning; ZooMS; Vendeltid; Vikingatid; järnålder; hantverk; Valsgärde;

    Abstract : Leather has been one of the most common crafting materials in human history. With its incredible versatility it has been used for clothes, shelter, books, armour, containers, decoration, and everything in between. READ MORE

  3. 2. A study of the triboelectricity of 2D materials: MoS2, WS2 and MoO3 : Analyzing measurements from a triboelectric nanogenerator

    University essay from Mittuniversitetet/Institutionen för naturvetenskap

    Author : Simon Kilman; [2022]
    Keywords : 2D-material; MoS2; WS2; MoO3; triboelektrisk nanogenerator; TENG; triboelektrisk effekt; triboelektrisk serie; kontaktelektrifiering.;

    Abstract : Detta projekts mål har varit att undersöka tre olika 2D-materials triboelektriska egenskaper och därmed placera dem i en triboelektrisk serie. Detta utfördes genom att använda en triboelektrisk nanogenerator (TENG) och mäta den resulterande spänningen. Tio stycken motmaterial applicerades mot varje 2D-material på nanogeneratorn. READ MORE

  4. 3. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  5. 4. Submillimeter 3D surface reconstruction of concrete floors

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Björn Hagström; Hampus Wallström; [2022]
    Keywords : Submillimeter; Structured light; Sinusoidal phase shift; Concrete; Surface reconstruction; Defocused binary pattern;

    Abstract : During the creation of any concrete floor the concrete needs to be grinded down from it's very rough newly poured form to a more usable floor surface. Concrete floor grinding is very special in that the work area is often immensely large while the height difference on the surface is incredibly small, in-fact the the largest local difference of the surface from a peek to a valley during the grinding process is submillimeter and goes down to micrometer scale.

  6. 5. Additive Manufacturing of Strain Gauges : A Study of the Feasibility of Printing Strain Gauges Using Inkjet Printing

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Karin Wennersten; [2022]
    Keywords : Additive manufacturing; strain gauge; inkjet; IJP; AJP; aerosol jet;

    Abstract : Additive manufacturing (AM) also commonly known as 3D-printing is a manufacturing method which creates parts from adding layer into another. In the field of printed electronics Inkjet printing (IJP) and Aerosol Jet printing (AJP) are the most common AM techniques. READ MORE
