  1. 11. Transmission of slow highly charged ions through nano-structures

    Författare :Nadeem Akram; Reinhold Schuch; Friedrich Aumayr; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Highly charged ions; nano-structures; nanocapillaries; ion-guiding; fysik; Physics;

    Sammanfattning : This thesis is based on experimental investigations of transmitting slow highly charged ions through nano-structures of various cross-sections. Transmission through rhombic and rectangular nanocapillaries in muscovite and phlogopite mica, respectively, is used to study the guiding and shaping of highly charged ion beams. LÄS MER

  7. 15. Novel monogalactoside galectin inhibitor scaffolds : Guiding selectivity with heteroaromatic interactions

    Författare :Alexander Dahlqvist; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galectin; Galectin inhibitor; Heterocycles; C-glycoside; Medicinal chemistry; Organic chemistry; Hydroboration; Diastereoselective; Galactose;

    Sammanfattning : Carbohydrates are involved in many cellular processes, and most biomolecules are glycosylated. Thesemodifications are used in biological systems as information carriers, helping regulate organization on the cell surfaceand interactions between cells and the environment. LÄS MER
