Synthetic Efforts to Investigate Structure-Property Relationships in Dyes for Dye- Sensitized Solar Cells
(Doctoral theses at NTNU;2022:300, Doctoral thesis, 2022)With the backdrop of human-induced global warming in mind, the need for sustainable energy has never been larger. The Intergovernmental Panel on Climate Change presented in their recent assessment report that global warming ... -
Accelerating the understanding of chemistry: with path-sampling and human understandable machine learning algorithms
(Doctoral theses at NTNU;2022:289, Doctoral thesis, 2022)Understanding chemistry is essential for the optimization of reactions and the development of new reactions. Chemical reactions can be investigated by simulations without wasting any precious materials or be influenced by ... -
Synthesis and Characterization of Halogen Substituted 1,2,4-Triazolobenzodiazepines and Their α-Hydroxylated Metabolites
(Master thesis, 2022)Målet med denne masteroppgaven er å effektivt syntetisere seks ulike triazolobenzodiazepiner (7) og deres α-hydroksylerte metabolitter (6) fra det korresponderende benzofenonet (1), med fokus på triazolobenzodiazepinene ... -
Synthesis and Characterization of Nitro- and Fluoro-Substituted Triazolobenzodiazepines for use as Standards in Forensic Analysis
(Master thesis, 2022)Denne masteroppgaven omhandler syntese av nitro- og fluorsubstituerte triazolobenzodiazepiner (TBZD). Et økt forbruk av nye og uregistrerte TBZD på det ulovlige dopingmarkedet gjør det utfordrende for rettsmedisinske ... -
Comparison of Long-Range Atmospheric Transported Pollutants in Snow and Moss Samples from Svalbard
(Master thesis, 2022)Som en del av Arktis er Svalbard et fjerntliggende område med få lokale kilder som slipper ut forurensninger til miljøet. Til tross for dette er det observert høyere konsentrasjoner av forurensninger enn hva som er forventet ... -
