1. 1. Exploring time-extended complexity measures in magnetic systems

   University essay from Uppsala universitet/Materialteori

   Author : Jannes van Poppelen; [2023]
   Keywords : ;

   Abstract : Complexity, a fundamental concept in physics, encompasses phenomena spanning atomic to cosmic scales. The natural emergence of complexity can be explained by self-organized criticality. In this work, two complexity measures in magnetic systems are explored. READ MORE

3. 2. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Pranay Kumar Parsi; [2023]
   Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

4. 3. End-of-life wind blade recycling through thermal process

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Kerstin Benz; [2023]
   Keywords : Wind Turbine Blades; Recycling; Glass Fiber Reinforced Plastic; Molten Salt Pyrolysis;

   Abstract : Renewable energy production with wind turbines has been rising in the last 30 years and it is a crucial technology, which is necessary for the energy transition. As sustainable as the energy production of wind turbines is, the waste management of the blade material is not. Most of the blades end up on a landfill or get incinerated. READ MORE

5. 4. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Tobias Lindborg; [2022]
   Keywords : Lignin; Polymer; Renewable; Bioresource; Glass transition temperature; Nitrile; Polymer technology; Chemistry; Technology and Engineering;

   Abstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

6. 5. Temperature sensing on a linear wear test rig for plastic components

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Anton Grahn; Sebastian Granlund; [2022]
   Keywords : Accelerated Life Testing; Wear; ALT; Thermocouple; Thin Film RTD; 3D-Printing; PA12; Heat Flow; Accelererad livslängdstestning; ALT; Förslitning; Termoelement; Film RTD; 3DUtskrivning; PA12; Värmeflöde;

   Abstract : För att verifiera att komponenter håller under en förväntad livslängd kan en Accelererad Livstids Testning (ALT) användas. En av huvudaspekterna som kan förstöra ett ALT-test av plastkomponenter är om kontakttemperaturen överstiger glasövergångstemperaturen. Detta eftersom det förändrar testkomponentens materialegenskaper. READ MORE
