  1. 1. Synthesis of 11C-labelled Alkyl Iodides Using Non-thermal Plasma and Palladium-mediated Carbonylation Methods

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Eriksson; Uppsala universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; isotopic labelling; carbon-11; alkyl iodides; acrylamides; specific radioactivity; carbonylation; carbon monoxide; non-thermal plasma; PET; Organisk kemi;

    Abstract : Compounds labelled with 11C (β+, t1/2 = 20.4 min) are used in positron emission tomography (PET), which is a quantitative non-invasive molecular imaging technique. It utilizes computerized reconstruction methods to produce time-resolved images of the radioactivity distribution in living subjects. READ MORE

    Abstract : Popular Abstract in Swedish Tensider, eller amfifiler, är molekyler som består av en hydrofil (”vattenälskande”) och en hydrofob (”vattenskyende”) del. Denna dualistiska karaktär ger tensider speciella egenskaper av vilken den viktigaste är att den självaggregerar i en del lösningsmedel, som i de allra flesta tillämpningar är vatten. READ MORE

    Abstract : Popular Abstract in Swedish Om vi använder allt tillgängligt fossilt bränsle kommer detta leda till att havsnivån ökar med mer än 50 m, enligt nya rön [1]. Även om detta hot ligger långt in i framtiden, finns ett flertal akuta problem kopplade till den globala uppvärminingen. READ MORE
