Semisyntese av paclitaxel - et historisk perspektiv
(Bachelor thesis, 2023)Det viktige kreftbehandlingsstoffet paclitaxel, som kommer fra barken på stillehavsbarlinden, er ikke bærekraftig å ekstrahere fra den saktevoksende planten. Blant andre alternativer for anskaffelse er semisyntese av ... -
Separation and Characterization of Byproducts from Iodixanol Synthesis by HPLC-UV, LC-MS and UPLC-MS
(Master thesis, 2023)Dimeren iodixanol er et virkestoff i kontrastmiddel og et av hovedproduktene til GE HealthCare Lindesnes. Noen biprodukter fra iodixanolproduksjon er ikke identifisert, selv om de blir kvantifisert for hver batch. Disse ... -
Series of studies to investigate different methods for rinsing runoff water from roads
(Master thesis, 2018)Runoff from roads contains a wide range of pollutants such as inorganic compounds and organic compounds which can be dissolved or particle-bound. The dissolved contaminates are often more mobile and therefore also bioavailable ... -
Sewage sludge biochars as effective PFAS-sorbents
(Peer reviewed; Journal article, 2022)The use of sewage sludge to produce biochar-based sorbents for per- and polyfluoroalkyl substances (PFAS) removal from water and soil may be an economically and environmentally sustainable waste management option. This ... -
Shape of a frictional fluid finger
(Peer reviewed; Journal article, 2023)Frictional fluid dynamics describes the displacement patterns that arise when a confined mixture of liquid and grains are displaced by an immiscible fluid under pressures that are too small to cause drainage into single ... -
Silica-modified bismutite nanoparticles for enhanced adsorption and faster solar photocatalytic degradation of methylene blue
(Peer reviewed; Journal article, 2023)Herein, we report the synthesis of silica-modified self-assembled structures of bismutite (BSC) through a facile hydrothermal route. The incorporation of silica into the hybrid led to improved adsorption of cationic methylene ... -
Silicon for the direct process to methylchlorosilanes
(Doktor ingeniøravhandling;1992:67, Doctoral thesis, 1992)The available literature in the field of the direct process to methylchlorosilanes has been reviewed and commented. An apparatus and operation procedure have been developed to study the effect of structure on the direct ... -
SILISIUM PRODUKSJONSPROSESS. ENERGI OG EKSERGI ANALYSE FOR HOLLA SILISIUM SMELTEVERK.
(Master thesis, 2012)Metallurgisk industri prøver å forene kvalitet av rå varer med relativt lav pris og den beste teknologien. Eksergi gjør det mulig å finne og kvantifisere evnen til forbedring av termiske og kjemiske prosesser. Selve eksergi ... -
Simple generalized reaction conditions for the conversion of primary aliphatic amines to surfactant-like guanidine salts with 1H-pyrazole carboxamidine hydrochloride
(Journal article, 2017)Improved reaction conditions for the electrophile reaction between a free aliphatic amine and 1H-pyrazole carboxamidine have been discovered. The surfactant-like guanidine salts, which are often hard to work with, were ... -
A simple hanging mercury drop electrode
(Peer reviewed; Journal article, 2000)A device producing reproducible hanging mercury drops at the end of a glass capillary is described. Mercury flow through th capillary is controlled by means of a closing needle actuated by an electromagnetic relay. The ... -
A simplified pore-scale model for slow drainage including film-flow effects
(Peer reviewed; Journal article, 2023)Liquid-filled corners and capillary bridges can establish networks connecting seemingly isolated clusters during drainage in porous media. Coupled with drainage through the bulk of pores and throats, the flow through these ... -
Simulating absorption spectra of flavonoids in aqueous solution: A polarizable QM/MM study
(Journal article; Peer reviewed, 2020)We present a detailed computational study of the UV/Vis spectra of four relevant flavonoids in aqueous solution, namely luteolin, kaempferol, quercetin, and myricetin. The absorption spectra are simulated by exploiting a ... -
Simulating electron-avalanche-driven positive streamers in dielectric liquids
(Doctoral theses at NTNU;2020:289, Doctoral thesis, 2020)Summary of thesis: The thesis presents a novel predictive model for simulating positive streamers in dielectric liquids. Such liquids are commonly used for electrical insulation of high-power equipment, for example power ... -
Simulating the unwinding of DNA - Method development, application and didactic dissemination.
(Doctoral theses at NTNU;2019:13, Doctoral thesis, 2019)Understanding diseases related to DNA requires insight into the nature of DNA dynamics, specifically how the dynamics affects the equilibrium properties. The mesoscopic Peyrard-Bishop-Dauxois model has been able to ... -
Simulation model for the propagation of second mode streamers in dielectric liquids using the Townsend-Meek criterion
(Journal article; Peer reviewed, 2018)A simulation model for second mode positive streamers in dielectric liquids is presented. Initiation and propagation is modeled by an electron-avalanche mechanism and the Townsend–Meek criterion. The electric breakdown is ... -
