  2. 1. New methods and reagents for small scale synthesis of phosphor organic compounds with focus on the phosphonic acids and their analogues

    Author : Rikard Wärme; Dan Johnels; Jacek Stawinski; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; micro scale; phosphorus oxyacids; solid phase; chlorination; fluorination; radiolabelling; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : The development of a synthetic method of radiolabelled methylphosphono-fluoridates on a milligram scale is presented. The aim of this method is, besides affording high yield, to choose reaction pathways and reagents so that handling and transfer of labelled toxic substances is minimised, thereby reducing the risk of exposure as much as possible.

    Abstract : In Sweden, housing accounts for about 23% of all energy consumption. Sweden wants to reach net zero carbon emissions by 2045; as such, it is likely that energy-saving measures for housing will be needed. Many existing buildings have been in operation for 50 years or more and are therefore in need of modernisation. READ MORE

  6. 4. Proteome Profiling of Strawberry and Characterization of a Bet v 1-Homologous Allergen

    Abstract : Strawberry (Fragaria ananassa) is an economically important crop, and recognised as an important source of antioxidants and bioactive compounds with health promoting effects. Yet increased incidence of allergy puts a limit to the choice of food for an increasing percentage of the population. READ MORE

  7. 5. Trust, Threat, and Stable Peace. : Swedish Great Power Perceptions 1905-1939

    Author : Rikard Bengtsson; Statsvetenskapliga institutionen; []
