1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Ahsan Ali; [2023]
   Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

3. 2. Sortase A coupling of the recombinant partial silk proteins 4Rep-Srt and G-/G5-CT to understand the structure of silk fiber

   Master-uppsats, KTH/Proteinvetenskap

   Författare :Ellen Adlerz; [2023]
   Nyckelord :4RepCT; 4Rep-Srt; G- G5-CT; Sortase A coupling; recombinant silk protein; 4RepCT; 4Rep-Srt; G- G5-CT; Sortase A-koppling; rekombinant silkesprotein;

   Sammanfattning : Spindelsilke är ett intressant material på grund av dess biokompatibilitet och därav användning som biomaterial. Det är jämförbart med konstgjorda material när det gäller styrka och elasticitet, och i kombination med biokompatibiliteten, är spindelsilke eftertraktat inom det medicinska området. LÄS MER

4. 3. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Sammanfattning : 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. LÄS MER

5. 4. Optimerad sandwichvägg i prefabricerad betong

   Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Majed Alsmail; Baqer Rubaij; [2023]
   Nyckelord :sandwich elements; thin concrete slabs; outer concrete layer; anchoring; anchoring systems; granular rupture in outer layer; anchor pull-out; adhesion; outer layer failure; loads; reinforcement; recesses; sandwichelement; tunna betongskivor; yttre betongskiva; förankring; förankringssystem; konbrott i yttre skivan; bygel utdrag; vidhäftning; brott i ytterskiva; belastningar; armering; ursparningar;

   Sammanfattning : As part of the work in this project, a literature review is conducted to determine the optimal thickness of the outer concrete layer in prefabricated concrete sandwich elements. These elements are used as exterior walls in buildings and consist of a load-bearing inner concrete layer, an intermediate insulation layer, and an outer concrete layer that forms the building's facade.

7. 5. Multifunctional ice and snow repellent coatings for photovoltaic modules

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

   Författare :Gunnar Sandkvist; [2023]
   Nyckelord :sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

   Sammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER
