TD-DFT based fine-tuning of molecular excitation energies using evolutionary algorithms
(Journal article; Peer reviewed, 2016)An evolutionary de novo design method is presented to fine-tune the excitation energies of molecules calculated using time-dependent density functional theory (TD-DFT). The approach is applied to a π-conjugated molecular ... -
Teaching complex molecular simulation algorithms: Using self‐evaluation to tailor web‐based exercises at an individual level
(Peer reviewed; Journal article, 2020)It is quite challenging to learn complex mathematical algorithms used in molecular simulations, stressing the importance of using the most advantageous teaching methods. Ideally, individuals should learn at their pace and ... -
Temperature anisotropy at equilibrium reveals nonlocal entropic contributions to interfacial properties
(Journal article, 2018)Density gradient theory for fluids has played a key role in the study of interfacial phenomena for a century. In this work, we revisit its fundamentals by examining the vapor-liquid interface of argon, represented by the ... -
Temporal dynamics of carbon sequestration in coastal North Atlantic fjord system as seen through dissolved organic matter characterisation
(Peer reviewed; Journal article, 2021)Fjord systems in higher latitudes are unique coastal water ecosystems that facilitate the study of dissolved organic matter (DOM) dynamics from surface to deeper waters. The current work was undertaken in the Trondheim ... -
Temporal Trends and Age-Dependent Sex Differences in Chlorinated Paraffin Accumulation in Moose
(Peer reviewed; Journal article, 2022)Previous studies have found relatively high chlorinated paraffin (CP) concentrations in moose (Alces alces) compared with other wildlife from Scandinavia. To explore CP accumulation behaviors in this long-lived terrestrial ... -
Ten-year trends in atmospheric mercury concentrations, meteorological effects and climate variables at Zeppelin, Ny-Ålesund
(Journal article; Peer reviewed, 2013)Results from ten years of gaseous elemental mercury (GEM) measurements at Zeppelin station, Ny-A° lesund, Svalbard, show no overall annual trend between 2000 and 2009. Seasonal trend analysis showed significantly ... -
Ten-year trends of atmospheric mercury in the high Arctic compared to Canadian sub-Arctic and mid-latitude sites
(Journal article; Peer reviewed, 2013)Global emissions of mercury continue to change at the same time as the Arctic is experiencing ongoing climatic changes. Continuous monitoring of atmospheric mercury provides important information about long-term trends in ... -
The anti-cancer potential of sulfoquinovosyl-derivatives from marine sources
(Bachelor thesis, 2020)Cancer is among the deadliest diseases known to man. What makes cancer more challenging to treat than other diseases is the fact that it, by its very nature, undergoes rapid and frequent mutations, making every case – to ... -
The antihypertensive activity of benzimidazoles and the binding of its derivatives to the AT1 receptor
(Bachelor thesis, 2021)For å undersøke den antihypertensive effekten til benzimidazol derivater og effekten av ulike substituenter, på benzimidazol kjernemolekylet, på den antihypertensive effekten vil denne oppgaven se på bindingen av inverse ... -
The appliance and synthesis of natural antibiotic (+)-negamycin
(Bachelor thesis, 2020)I denne oppgaven fremheves og diskuteres fordeler og ulemper ved det naturlige antiobiotikumet (+)-negamycin. Disse består blant annet av dens ytelse innenfor medisin samt toksisitet for potensielle pasienter. En sammenligning ... -
The catalytic direct conversion of methane to methanol with metal-exchanged ZSM-5
(Bachelor thesis, 2021)Metangass er en av klimagassene som bidrar mest til global oppvarming, og er en rik ressurs som kan brukes i den petrokjemiske industrien ved å omdanne den til metanol. En mer bærekraftig mekanisme for konvertering gjøres ... -
The Dalton quantum chemistry program system
