1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

   University essay from KTH/Fiber- och polymerteknologi

   Author : Felix Bogdan; [2023]
   Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

   Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

3. 2. Graphene Based Aqueous Ammonium Dual-Ion Batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Arvid Sandberg; [2023]
   Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

   Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

4. 3. Synthesis and characterization of lactic acid-based elastomers

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Afsaneh Makhdoumi; [2023]
   Keywords : Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

   Abstract : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

5. 4. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

   University essay from KTH/Kemiteknik

   Author : Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
   Keywords : Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

   Abstract : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. READ MORE

6. 5. Investigating Yttrium Ruthenate Pyrochlore as an Anodic Electrocatalyst in Proton Exchange Membrane Water Electrolysis

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Kneev Sharma; [2023]
   Keywords : ;

   Abstract : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. READ MORE
