Climate change's effect on transportation of PCBs
(Bachelor thesis, 2022)Studier indikerer at klima endringer og høyere temperaturer stimulerer transporten, oppdelingen og volatiliteten til polyklorerte bifenyler (PCBer). PCBer er vedvarende organiske forurensninger, som er giftige for miljøet. ... -
CO2 hydrogenation to light olefins over metal supported SAPO-34
(Bachelor thesis, 2021)Direkte hydrogenering av karbondioksid til høyverdige kjemikalier er en lovende strategi for å lukke karbonsyklusen ved å redusere overskuddet av karbondioksid i atmosfæren og samtidig minske avhengigheten av fossile ... -
CO2 induced phase transitions in diamine-appended metal-organic frameworks
(Journal article; Peer reviewed, 2015)Using a combination of density functional theory and lattice models, we study the effect of CO2 adsorption in an amine functionalized metal organic framework. These materials exhibit a step in the adsorption isotherm ... -

Combating Antibiotic Resistance by Chemical Synthesis: Creation of new varieties of Glycopeptide Antiobiotics based on Vancomycin
(Bachelor thesis, 2021)The emergence of multi-resistant bacteria has been described by WHO as the gravest disease threat we face, claiming up to 700,000 lives annually. Antibiotics of last-resort, such as the glycopeptide class antibiotic ... -
Combined Effects of Silver Nanoparticles and 17α-ethinyl estradiol on Turbot (Scophthalmus maximus)
(Master thesis, 2015)Due to their antimicrobial properties silver nanoparticles are one of the most used nanomaterials in the commercially available products nowadays. The exponential increase in production of nanomaterials raises concerns ... -
A comparative study of experiments and theories on steady-state evaporation of water
(Journal article, 2022)A precise description of energy and mass transport across the liquid-vapor interface of water is central in dis- ciplines spanning from climatology to seawater desalination. We present a critical assessment of six recent ... -
Comparing PFAS concentrations in non-functional recycled and post-consumer textiles: Implications for a toxic-free circular economy
(Master thesis, 2023)Tilstedeværelse av per- og polyfluoralkylstoffer (PFAS) i tekstiler regnes som en hinder for å oppnå materialsykluser fri for miljøgifter under ønsket om å øke resirkuleringsraten for tektiler under EU’s handlingsplan for ... -
Comparing Structural Features of Flavonoid Derivatives for Enhancing Inhibition of Multidrug Resistant Cancer Mediating ABC transporters: P-gp and BCRP
(Bachelor thesis, 2021)ABC transporters are a family of transmembrane proteins that serve multiple physiological functions by pumping unwanted substances out of different cells (efflux).(1) However, some ABC transporters, including Breast Cancer ... -
Comparison Between 8-Methoxypsoralen and 5-Aminolevulinic Acid in Killing T Cells of Photopheresis Patients Ex Vivo
(Journal article; Peer reviewed, 2018)Background and Objective Extracorporeal photopheresis (ECP), an established modality for cutaneous T‐cell lymphoma (CTCL) and graft‐versus‐host disease, involves ex vivo treatment of isolated leukocytes of a patient with ... -
Comparison of Hygrometers for Monitoring of Water Vapour in Natural Gas
(Doctoral theses at NTNU;2015:21, Doctoral thesis, 2015)To be able to maintain a safe, regular and economic production and transportation of natural gas, it is crucial to be able to accurately quantify the water vapour concentration in the gas. Underestimation of the water ... -
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 ... -

Comparison of Students' Perceived Learning in Two Similar Lab Courses with Different Teaching Staffs
(Journal article, 2020)At the Norwegian University of Science and Technology (NTN), two subjects with similar chemistry laboratory exercises have different practices with respect to the use of permanent and temporary staffs. In an ever-increasing ... -
Comparison of the catalytic potential of ionic liquids and heterogeneous metallic catalysts to prepare cyclic carbonates from carbon dioxide and epoxides
(Bachelor thesis, 2023)Fiksering av CO2 for å produsere nyttige kjemikalier har blitt studert lenge. Spesielt syntesen av sykliske karbonater fra CO2 og epoksider har blitt utforsket. Denne raporten har foksuert på to forskjellige katalysatorer ... -
Complex Frequency-Dependent Polarizability through the π → π* Excitation Energy of Azobenzene Molecules by a Combined Charge- Transfer and Point-Dipole Interaction Model
(Journal article; Peer reviewed, 2014)The complex frequency-dependent polarizability and π → π* excitation energy of azobenzene compounds are investigated by a combined charge-transfer and point-dipole interaction (CT/PDI) model. To parametrize the model, we ... -
