Synthesis and in vitro evaluation of a novel thienopyrimidine with phototoxicity towards rat glioma F98 cells
(Peer reviewed; Journal article, 2022)Glioblastoma multiforme is one of the most aggressive cancer forms in humans, and has low recovery rates after surgery, ionizing radiation and chemotherapy. Therefore, there is a high interest in the development of new ... -
Studies of long-range transported pollutants in proglacial lakes/ponds in Ny-Ålesund area
(Master thesis, 2022)Global warming has been affecting several aspects of the environment, e.g. physical, ecological, and economic. Therefore, research on the different aspects of the global warming process is going on continuously. Arctic ... -
Deposition Patterns of PAHs, PCBs, and Selected Elements in Snow on Glaciers - Covering a Latitudinal Gradient from Southern Norway (60.54°N) to Svalbard (78.87°N)
(Master thesis, 2022)Svalbard is a remote Arctic Archipelago, often considered to have a pristine environment. However, volatile and persistent compounds have been suggested to be transported from lower latitudes to the Arctic via long-range ... -
Gold Complex Preparation, Catalysis and Catalyst Activation
(Doctoral theses at NTNU;2022:195, Doctoral thesis, 2022)Gold complexes and salts have proven to be exceptional catalysts for the activation of carbon-carbon multiple bonds towards nucleophilic attack. Gold catalysts allow for the synthesis of complex products under mild conditions. ... -
A sensitive and compact optical detector based on digital lock-in amplification
(Peer reviewed; Journal article, 2021)We report a sensitive, fixed-wavelength, lock-in-based optical detector built from a light-emitting diode, two colour filters, a photodetector, a small number of discrete analogue components, and a low-cost microcontroller ... -
Synthesis of 3'-O-esterified sulfoquinovosyl glycerol derivatives
