1. Analytical Methods for High Molecular Weight UV Stabilizers
Master-uppsats, KTH/KemiSammanfattning : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). LÄS MER
2. Exploring an alternative metabolic pathway for production of adipic acid - a study on homocitrate synthase
Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologiSammanfattning : Adipic acid is considered as the most valuable dicarboxylic acid with industrial use; however, its production is heavily petroleum-based. This non-natural metabolite can be produced de novo through different metabolic pathways, one of which is the alpha-ketoacid elongation pathway. LÄS MER
3. Identification of Environmental Plastic Samples from a Caribbean Beach Survey by Near-Infrared Spectroscopy with the MicroNIR and Chemometric Analysis
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : MicroNIR is a portable near-infrared diffuse reflection spectroscope. Its suitability for identifying environmental plastic polymers was evaluated through a series of performance tests. The plastic samples were collected during a beach survey in the Caribbean. First a reference database was built by analysing a series of reference plastic polymers. LÄS MER
4. Developments in the End-of-Life management of plastics A Western European Overview: moving away from disposal
Magister-uppsats, Lunds universitet/Internationella miljöinstitutetSammanfattning : Plastic materials come in a variety of forms from non-renewable resource based thermosets and thermoplastics to renewable resource based bio-plastics each of which have unique qualities and properties. These materials are seeing ever increasing production and consumption rates throughout Western Europe, being utilized in a growing number of products which inevitably enter the waste stream upon end of life.
