UV degradation of natural and synthetic microfibers causes fragmentation and release of polymer degradation products and chemical additives
(Peer reviewed; Journal article, 2020)A high proportion of the total microplastic (MP) load in the marine environment has been identified as microfibers (MFs), with polyester (PET) and polyamide (PA) typically found in the highest abundance. The potential for ... -
Valence excitation energies in multilevel coupled cluster
(Master thesis, 2017)This is a benchmark study, for valence excitation energies in the multilevel coupled cluster (MLCC) framework. The information resulting from lower level of theory is used to generate correlated natural transition orbitals ... -
Validating reproducible methods for the analysis of microplastics in environmental samples
(Master thesis, 2022)Harmoniserte eller sammenlignbare metoder for kvantifisering av mikroplast er avgjørende for å kartlegge, karakterisere og øke nøyaktigheten av å beskrive omfanget og endringene over tid av mikroplastforurensning. Slike ... -

(Master thesis, 2019)Sweco Norge AS har gjennomført en vurdering av lokal luftkvalitet med spredningsberegning av nitrogendioksider (NO2) i forbindelse med en reguleringsplan i Fagertunveien, Trondheim. Til dette blir luftkvaliteten vurdert ... -
Vanningsteknikk og fosfor-gjødsel som agronomiske tiltak for reduksjon av mengden arsen i jord og risavling
(Bachelor thesis, 2022)Arsen introdusert i jord via irrigasjon med arsenforurenset grunnvann muliggjør arsenakkumulering og -opptak av planter, og utgjør en helsemessig risiko da arsen når menneskets næringskjede. Dette er forekommende i Bangladesh ... -
Vapour phase conversion of acetic acid over metal oxide catalysts at hydropyrolysis conditions.
(Master thesis, 2023)De utslippet av drivhusgasser i løpet av de siste 150 årene har ført til klimaendringer, noe som tvinger verden til å finne alternative måter å produsere transportbrensel og plattformkjemi på. Tre er et lett tilgjengelig ... -
Veikart for industriell dyrking av tare i Trøndelag
(Research report, 2024)SAMMENDRAG • Med behovet for en mer bærekraftig matproduksjon (mer mat fra havet) og vedtatte klimamål (binding av CO2) er det en ønsket utvikling at den globale produksjonen av dyrket tare skal vokse frem mot 2030. • ... -
Vellykket Organisk Kjemisk Vintermøte 2020
(Journal article, 2020)Organisk Kjemiske Vintermøte (OKV35) ble arrangert 9.-12. januar, og samlet 130 deltakere fra de norske universitetene og industri med tiknytning til feltet. Møtet viser at organisk kjemi på tross av en utfordrende ... -
Vibrational motion in molecules
(Master thesis, 2014)Zero-point vibrational corrections are carried out with analytical geometry and property derivatives at DFT level. This correction is obtained using a variation-perturbation approach, and is carried out around a variationally ... -
Vinyl Amide Reactions in the Presence of Gold(I) Catalyst

Viscosity, structure and glass formationin the AlCl3-ZnCl2 system
(Dr. ingeniøravhandling, 0809-103X; 2001:36, Doctoral thesis, 2001)Thermodynamic, viscous and structural properties of melts and glasses in the AlCl3-ZnCl2 system have been investigated. The two pure components are fundamentally different in the molten state. Both metal atoms are four ... -
A volume-averaged model for acoustic streaming induced by focused ultrasound in soft porous media
(Peer reviewed; Journal article, 2023)Equations describing acoustic streaming in soft, porous media driven by focused ultrasound are derived based on the assumption that acoustic waves pass through the porous material as if it were homogeneous. From these ... -
