Tailoring the oxide surface composition of stainless steel for improved OER performance in alkaline water electrolysis
(Peer reviewed; Journal article, 2022)There is a strong desire to replace bulk nickel electrodes for oxygen evolution reaction (OER) with a cheaper and more active steel material in alkaline water electrolyser (AWE). However, implementing an activation procedure ... -
Tailoring the structure of Co-Mo/mesoporous γ-Al2O3 catalysts by adding multi-hydroxyl compound: A 3000 kt/a industrial-scale diesel ultra-deep hydrodesulfurization study
(Journal article; Peer reviewed, 2018)Ever-increasing concern on environmental impacts (e.g., sulfur pollution) by fossil fuels has triggered the research on hydrodesulfurization (HDS). In this work, Co-Mo nanoparticles were deposited on the mesoporous γ-Al2O3 ... -
Taking a trip to the shelf: Behavioral decisions are mediated by the proximity to foraging habitats in the black-legged kittiwake
(Journal article; Peer reviewed, 2017)For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability. Worldwide, these marine habitats are being altered by changes in climate and ... -
Taming Electrons in Pt/C Catalysts to Boost the Mesokinetics of Hydrogen Production
(Peer reviewed; Journal article, 2022)Taming the electron transfer across metal–support interfaces appears to be an attractive yet challenging methodology to boost catalytic properties. Herein, we demonstrate a precise engineering strategy for the carbon surface ... -
Tandem Catalytic Upgrading of Biomass Fast-Pyrolysis Constituents to Fuels
(Doctoral theses at NTNU;2019:51, Doctoral thesis, 2019)The increasing human population and it’s associated economic, environment and geopolitical demands towards sustainable transport energy have advanced research onto renewable liquid fuel production and aviation fuel range ... -
Tandem hydrodeoxygenation catalyst system for hydrocarbons production from simulated bio-oil: Effect of C-C coupling catalysts
(Peer reviewed; Journal article, 2021)Research in the sustainable conversion of biomass to fuels and chemicals is a necessity for the reduction of the carbon footprint in transport energy. Herein, we demonstrate an efficient tandem catalyst to selectively ... -
Tap av areal for sjøørret (Salmo trutta) i elver og bekkar i Ålesund kommune
(Bachelor thesis, 2023)Samandrag Denne bacheloroppgåva kvantifiserer tapet av anadromt elveareal, innsjøareal og elvestrekning i 29 vassdrag i Ålesund kommune. Dagens tilstand er samanlikna med «original» tilstand, som vil seie den opphavelege ... -
Tap av gruntvannsområder i indre Nordfjord som følge av utfylling og mudring.
(Bachelor thesis, 2023)I historisk sammenheng har elvedaler innerst i fjordarmer vært viktige bosetningsområder, og dannet grunnlaget for mange av de største tettstedene i Norge i dag. Dette har ført til behov for infrastruktur og sentrumsutvikling, ... -
