  1. 11. Barrier Plastics, Processing of Wheat Gluten and A New Method to Measure Permeability

    Författare :Henrik Ullsten; KTH; []
    Nyckelord :;

    Sammanfattning : One way to extend the shelf life for foodstuff is to usemodified atmosphere packaging (MAP). It is important that MAPare gas tight or in some rare cases permselective to preservethe right gas mix. LÄS MER

  3. 12. Design and Synthesis of Amine Building Blocks and Protease Inhibitors

    Författare :Susana Ayesa Alvarez; Bertil Samuelsson; Thomas Olsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : The first part of this thesis addresses the design and synthesis of amine building blocks accomplished by applying two different synthetic procedures, both of which were developed using solid-phase chemistry. Chapter 1 presents the first of these methods, entailing a practical solid-phase parallel synthesis route to N-monoalkylated aminopiperidines and aminopyrrolidines achieved by selective reductive alkylation of primary and/or secondary amines.

  4. 13. Characterisation of PFASs and Organofluorine in Freshwater Environments : Transfer from water to land via emergent aquatic insects

    Författare :Alina Koch; Thanh Wang; Micael Jonsson; Leo W. Y. Yeung; Anna Kärrman; Lutz Ahrens; Jonathan Martin; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFASs; riparian zone; emergent aquatic insects; terrestrial consumers; stable isotopes; organofluorine mass balance; AFFF; point sources;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are anthropogenic contaminants of emerging concern, because many are highly persistent to degradation and have been linked to adverse effects in humans as well as their ubiquitous spread in aquatic environments. This thesis investigated distribution of PFASs and organofluorine in freshwater environments impacted by PFAS point sources. LÄS MER

  5. 14. Analysis of Perfluoroalkyl Acids in Swedish Biota : Temporal trends, tissue distribution and toxicity

    Författare :Katrin Holmström; Urs Berger; Gregg Tomy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PFOS; PFAS; pollutant; Baltic guillemot; peregrine falcon; Monoporeia affinis; time trend; toxicity; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. LÄS MER

  7. 15. Design & Synthesis of Protein Interacting Affinity Ligands and Protease Inhibitors

    Författare :Charlotta Lindquist; Hans Adolfsson; Fredrik Almqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Sammanfattning : There is a growing need of both protein drugs and synthetic drugs in the fight against many life-threatening diseases. The first part of this thesis deals with the design and synthesis of high affinity binding ligands for the purification of protein drugs. LÄS MER
