1. Test rig for evaluation of protective coating against molten aluminum
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Today, many methods test the lifetime of coatings, but none focus on testing protective coatingsin a non-oxidizing environment. Hence, this master thesis developed a method to test the life-time of a protective coating against molten aluminum. LÄS MER
2. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process
Master-uppsats, Karlstads universitetSammanfattning : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

3. Isolation of an ammonia-tolerant syntrophic butyrate-oxidizing bacterium originating from a thermophilic biogas digester
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Syntrophic relationships between fatty acid degrading bacteria and hydrogenotrophic methanogens are important for a well-functioning anaerobic degradation process during biogas production from organic waste material. This is particularly important in biogas processes fed protein-rich material as their degradation gives rise to high levels of ammonia, which inhibits many microorganisms. LÄS MER
4. Brikettering av stålspån från skärande bearbetning : Sambandet mellan tryck och densitet
M1-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknikSammanfattning : Återvinning av stål är väsentligt av både hållbara och ekonomiska skäl. Stora mängder metallspånor bildas vid olika skärande bearbetningsmetoder under diverse tillverkningsprocesser. Då löst briketterade spånor eller lösa spånor lätt sprids i ljusbågsugnen vid omsmältningen oxideras de snabbt. LÄS MER
5. Vätgasutvecklande nickelelektroder : Vätningens inverkan vid beläggning med metallkloridbaserad lösning på nickelytor.
Master-uppsats, Mittuniversitetet/Avdelningen för kemiteknikSammanfattning : The production of hydrogen gas might be a part of the transition towards renewable fuels. Hydrogen can be used as fuel, electricity or heat with the help of an energy converter. In the production of hydrogen gas, electrolysis is usually used, which means that water is split into hydrogen and oxygen. LÄS MER
