(Journal article; Peer reviewed, 2008)Spinodal decomposition of hypermonotectic Al–6 wt.%Bi, Al–8 wt.%Bi and Al–6 wt.%Bi–8 wt.%Zn alloys has been investigated using synchrotron radiography. In the case of the 6 and 8 wt.%Bi binary alloys undercoolings of ... -
In situ synthesis of hybrid inorganic-polymer nanocomposites
(Journal article; Peer reviewed, 2018)Hybrid inorganic–polymer nanocomposites can be employed in diverse applications due to the potential combination of desired properties from both the organic and inorganic components. The use of novel bottom–up in situ ... -
In vitro studies of DNA condensation by bridging protein in a crowding environment
(Journal article; Peer reviewed, 2017)The macromolecules of the bacterial cell occupy 20–40% of the total cytosol volume, and crowded environments have long been known to compact and stabilize DNA. Nevertheless, investigations on DNA-protein binding are generally ... -
In vitro studies of ROR1 knockdown effects in hypoxic prostate cancer cells
(Master thesis, 2023)Bakgrunn: De fleste kreftsvulster inneholder hypoksiske områder, som er assosiert med resistans mot kreftbehandling og dårlig prognose. Kobber-64 (Cu-64) radiofarmaka har vokst frem som et teranostisk legemiddel i onkologi, ... -
