6. Post-processing for roughness reduction of additive manufactured polyamide 12 using a fully automated chemical vapor technique - The effect on micro and macrolevel
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Additive manufacturing has increased in popularity in recent years partly due to the possibilities of producing complex geometries in a rapid manner. Selective laser sintering (SLS) is a type of additive manufacturing technique that utilizes polymer powder and a layer-by-layer technique to build up the desired geometry. LÄS MER
7. Temporal and spatial variations of microplastic concentrations in surface waters in Gothenburg, Sweden.
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Temporal and spatial variations of microlitter (ML) concentrations in Gothenburg were measured by sampling surface water. ML was divided into three main categories; microplastics (MP), fibers (F) and other anthropogenic particles (OA). LÄS MER
8. Syntes av polyamider med candida antarctica lipase B
Master-uppsats, KTH/Skolan för bioteknologi (BIO)Sammanfattning : Polyamides are an important and versatile family of plastics commonly used both as construction plastics and fibers. The global consumption of polyamides has grown quickly, from 800 000 tons per year in 1990 to 2 500 000 tons per year in 2011. Polyamides are highly crystalline and consequently have high melting points. LÄS MER
9. Silver och vismut i plaster och färger : Källor till förhöjda halter i slam?
Kandidat-uppsats, Institutionen för biologi och miljö (BOM)Sammanfattning : Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. LÄS MER
