  1. 1. Microplastics in food webs- occurrence in Lake Vänern brown trout (Salmo trutta) and its main prey

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Hanna Nordström; [2023]
    Keywords : microplastic; freshwater; fish; brown trout; mikroplast; sötvatten; fisk; öring;

    Abstract : Over the past decade, research on microplastic pollution has gained significant attention. Research regarding microplastic occurrence in freshwater fish, however is still scarce. While possible pathways have been investigated, passive transfer via ingestion of prey, and possible bioaccumulation in different organs remains relatively unstudied. READ MORE

  3. 2. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Tobias Lindborg; [2022]
    Keywords : Lignin; Polymer; Renewable; Bioresource; Glass transition temperature; Nitrile; Polymer technology; Chemistry; Technology and Engineering;

    Abstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

  4. 3. Replacing waste streams in the healthcare industry by applied technology : Developing technology for a circular economy

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Marcus Skoog; Adam Backman; [2020]
    Keywords : Waste streams; Circular economy; Innovation; Recycling; Remanufacturing; Healthcare; Avfallsströmmar; cirkulär ekonomi; innovation; återvinning; hälsovård;

    Abstract : Background Waste has been around since humans started to create products. Today, it is a growing problem in the world; humans keep producing waste at a faster pace than we can handle. The world is becoming more conscious of our actions, and new solutions to manage and utilize the waste are desired. READ MORE

    Abstract : Element Materials Technology in Linköping is an independent material testing company that performs testing of materials to several big sectors, such as the Swedish Armed Forces and the aerospace industry. There is of great importance to characterize aging of materials to ensure material performance. READ MORE

  6. 5. Synthesis of Substituted Pyrrolidines

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Olof Sjölin; [2016]
    Keywords : Pyrrolidines; Multistep synthesis; Fragment-based drug design; Drug discovery; Organic chemistry;

    Abstract : The task of medicinal chemists in a drug discoveryproject is to synthesize/design analogues to the screening hits, simultaneouslyincreasing target potency and optimizing the pharmacological properties.  This requires a wide selection of moleculesto be synthesized, where both synthetic feasibility and price of startingmaterials are of great importance.
