Siah, Huey-San Melanie (Doctoral theses at NTNU;2020:167, Doctoral thesis, 2020)The field of gold(I)-catalysed reactions in organic chemistry has been expanding rapidly in the last two decades. Gold catalyses a diverse range of transformations and is especially useful in the activation of triple bonds ... -
Development of Gold Auranofin Analogues against Multidrug Resistant Bacteria Including Neisseria Gonorrhoeae
Simensen, Andreas Hegland (Bachelor thesis, 2024)Denne oppgaven vil presentere en gjennomgang av nyere forskning på medikamentet Auranofin,som ble godkjent av det amerikanske legemiddelverket (FDA) som et antiaritmetisk legemiddel. Auranofin er ett gull basert medikament ... -
Effect of seven different terthiophene π-spacers on dye performance in dye-sensitized solar cells
Almenningen, David Moe; Hansen, Henrik Erring; Buene, Audun Formo; Hoff, Bård Helge; Gautun, Odd Reidar (Journal article; Peer reviewed, 2022)To ensure high photocurrents from dye-sensitized solar cells (DSSC), it is important that the dye absorbs as much of the energy from the sunlight as possible. To achieve a wide absorption and cover larger parts of the solar ... -
