Vibrational spectroscopic study of pH dependent solvation at an Ge(100)-water interface during an electrode potential triggered surface termination transition.
(Journal article; Peer reviewed, 2018)The charge-dependent structure of interfacial water at the n-Ge(100)-aqueous perchlorate interface was studied by controlling the electrode potential. Specifically, a joint attenuated total reflection infrared spectroscopy ... -
Vinterdrift av 3G-kunstgressbaner: En undersøkelse av tungmetaller og salter i jord rundt en bane i Trøndelag
(Bachelor thesis, 2020)Varierende klimaforhold og stor etterspørsel for økt spilletid har ført til en drastisk økning i antall kunstgressbaner i Norge de siste tjue årene. Mesteparten av disse banene er 3G-baner som inneholder ifyll av gummigranulat. ... -
Vurdering av borevæske alternativer for Frigg feltutvikling
(Bachelor thesis, 2019)Valg av borevæsker er en vesentlig del av det teknologiske valget under planlegging av boreoperasjonen i feltutviklingsplanen. Den mest kostnadseffektive metoden er ønsket, men det miljømessige avtrykket er også et viktig ... -
Vurdering av nedbrytning basert på endringer i fysiske egenskaper for plasttekstil i lukkede oppdrettsanlegg
(Bachelor thesis, 2023)Dette er en oppgave som er skrevet i samarbeid med Maintech. Målet er å undersøke degraderingsegenskapene hos en plasttekstil som Fiizk benytter ved produksjon av dukposer for semi-lukkede oppdrettsmerder. Plasttekstilen ... -
Water as a monomer: synthesis of an aliphatic polyethersulfone from divinyl sulfone and water
(Peer reviewed; Journal article, 2022)Using water as a monomer in polymerization reactions presents a unique and exquisite strategy towards more sustainable chemistry. Herein, the feasibility thereof is demonstrated by the introduction of the oxa-Michael ... -

Waterborne chitosan-epoxysilane hybrid pretreatments for corrosion protection of zinc
(Journal article; Peer reviewed, 2016)Biopolymer-based systems are extensively studied as green alternatives for traditional polymer coatings, e.g., in corrosion protection. Chitosan–epoxysilane hybrid films are presented in this work as a chitosan-based ... -
Wavelength and orientation dependent capture of light by diatom frustule nanostructures
(Peer reviewed; Journal article, 2015)The ecological success of diatoms is emphasized by regular blooms of many different species in all aquatic systems, but the reason behind their success is not fully understood. A special feature of the diatom cell is ... -
Wear of carbon cathode lining in aluminium electrolysis cell: The effect of rotation speed in laboratory test cell
(Master thesis, 2014)The aluminium smelters are continually trying to increase their production either by designing high amperage cells or increasing the amperage on available cell designs. The service life for aluminium reduction cells is ... -
Wear of Carbon Refractory Materials in Silicon Furnaces
(Master thesis, 2016)The goal of this thesis was to investigate the internal morphology of different types of lining prepared with different installation techniques and different binders, and to see how the internal morphology affects the ... -
Weld thermal simulation of API 5CT L80 grade steel
(Peer reviewed; Journal article, 2021)The microstructure and mechanical properties of an API 5CT L80 casing grade steel (0.24C 0,4Si 1.4Mn CrNiCu) have been studied after performing weld thermal simulations (with and without subsequent tempering) applying a ... -
Welding and Mechanical Testing of Aluminium Alloys for use in Constructions
