1. Functional Bio-based Copolyesters: Properties and Abilities
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Genom ringöppningssampolymerisation av utvalda epoxider och anhydrider möjliggjordes en enkel strategi för att syntetisera funktionella sampolymerer. Sampolymererna hade förmågan att bilda tvärbundna material, och var dessutom benägna för både hydrolytisk och enzymatisk nedbrytning. LÄS MER
2. Development of Kraft Lignin and Coating Technique to Prepare Coated Urea Fertilisers with Increased Nutrient Use Efficiency
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Coating urea to prepare controlled release N-fertilizer has been considered as an effective way to increase its nutrient use efficiency, thus reduce its waste and the consequent harmful environmental impacts. Inorganic sulphur and synthetic polymers have been used in the industry as coating materials together with utilization of various types of expensive coating equipment which commonly requires also complicated technical setup and controls.
