  1. 16. Greening peptide chemistry by using NBP as solvent for SPPS

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Andrea Ölander; [2022]
    Keywords : SPPS; Green chemistry; Peptide Synthesis; Organic chemistry; Organisk kemi; Chemistry;

    Abstract : The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). READ MORE

  3. 17. Rare Earth Triflate/Alanine Catalysed Diels-Alder and Michael Reactions in Water and an Alternative Pyrrole Synthesis

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Albin Olsson; [2022]
    Keywords : Water; Green Chemistry; Synthesis; Organic Chemistry; Chemistry;

    Abstract : Large amounts of organic solvents are used within the field of chemistry and nearly everything is being discarded and is not reused. A way to reduce the environmental impact that this leads to is to use a safe and natural solvent that is easy to access, like water. READ MORE

  4. 18. Nanoscale characterisation of model Ni-Mo catalyst active phases

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Jonas Elmroth Nordlander; [2022]
    Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

    Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE

  5. 19. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Oscar Enander; [2022]
    Keywords : Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Abstract : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. READ MORE

  6. 20. Recycling methods for glass fibre-reinforced plastic polymers : Glass fibre composites in a circular economy?

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hanna Karlsson; [2022]
    Keywords : Composites; Glass; Fibre; Reinforced; Recycling; Circular economy; Circularity; Reinforcement; Plastic; Polymer; End-of-life; Reuse; Waste; Materials Chemistry; Chemistry;

    Abstract : The reinforced composite industry is expanding. This raises the need for more sustainable resource use and waste management. A concept to combat both is circularity, creating a loop between the raw resources and the waste. Two important parts of circularity are recycling and reusing. READ MORE
