1. 1. UV Curable Polymers for use in Additively Manufactured Energetic Materials

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexis Delorme; [2022]
   Keywords : Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

   Abstract : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. READ MORE

3. 2. Wastewater treatment with nanofiltration in pilot-scale

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Jane Quach; Safa al Basheer; [2018]
   Keywords : wastewater; nanofiltration; ultrafiltration; chemical precipitation; pilot-scale; chemical engineering; kemiteknik; Technology and Engineering;

   Abstract : During the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. READ MORE

4. 3. Nanofiltration of ultrafiltration permeate fom chemical wastewater

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Martin Gunnarsson; [2017]
   Keywords : total organic carbon; nanofiltration; wastewater; ultrafiltration; conductivity; chemical engineering; kemiteknik; Technology and Engineering;

   Abstract : The aim of this report was to investigate the possibility of further cleaning of the wastewater at Dow in Landskrona. Dow produces water based adhesives from acrylic monomers. The wastewater contains different metal ions, surfactants, residual monomers and polymers. READ MORE

5. 4. De-polymerization and Purification of Kraft Lignin Utilizing the Liquid-Lignin Phase

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Martin Sundin; [2017]
   Keywords : ALPHA; SLRP; Liquid-Lignin; Lignin; Technology and Engineering;

   Abstract : The effects of global warming are apparent and the work towards a sustainable future is underway. In order to reduce the environmental impact caused by the transportation sector, a transition from fossil fuels to those based on renewable resources are important. Using agricultural land to produce raw materials, e.g. READ MORE

6. 5. Leaching of Residual Monomers, Oligomers and Additives from Polyethylene, Polypropylene, Polyvinyl Chloride, High-density Polyethylene and Polystyrene Virgin Plastics

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Maria Björnsdotter; [2015]
   Keywords : Microplastics; Virgin plastic pellets; Residual monomers; Particle toxicity; GC-MS;

   Abstract : Plastic debris are accumulating in our oceans and are degraded into smaller pieces which eventually becomes small enough to be available to lower thropic level organisms. Microplastics, commonly defined as plastic particles <5 mm, are globally distributed and found at remote locations far away from industrialized and populated areas. READ MORE
