(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Water uptake by black carbon (BC)-containing aerosol was quantified in North American wildfire plumes of varying age (1 to ~40 h old) sampled during the SEAC4RS mission (2013). A Humidified Dual SP2 (HD-SP2) is used to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Waterlogged archaeological wood is often in need of consolidation prior to drying to prevent shrinkage and cracking of the object. There is a need for new greener materials (than for example polyethylene glycol) and methods ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Long-term laborious and thus costly monitoring of phosphorus (P) fractions is required in order to provide reasonable estimates of the levels of bioavailable phosphorus for eutrophication studies. A practical solution to ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Carbon nanostructured materials such as nanodiamonds and graphene are useful for various applications, but their low-energy production technologies remain an important challenge to overcome. Herein, the electrochemical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Ceria (CeO2) exhibits high reversible oxygen storage capacity at intermediate temperatures (500–800 °C) related to an extraordinary and not fully understood reduction of its surfaces. We have investigated pristine and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The orbital relaxation attendant on ionization is particularly important for the core electron ionization potential (core IP) of molecules. The Unitary Group Adapted State Universal Coupled Cluster (UGA-SUMRCC) theory, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Proton conducting oxide electrolytes find potential application in proton ceramic fuel cells and electrolyzers operating at intermediate temperatures, e.g. 400–600 °C. However, state-of-the-art proton conducting ceramics ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Temporal trends of industrial organic contaminants can show how environmental burdens respond to changes in production, regulation, and other anthropogenic and environmental factors. Numerous studies have documented such ...
-
(Master thesis / Masteroppgave, 2008)About 60% of the Chinese population lives in rural areas, where biomass and coal are the main sources of energy for cooking and heating. Indoor air pollution from household fuel burning is a major health concern, responsible ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The direct conversion of methane to methanol has the potential of substantially reducing methane emissions and flaring, as such a process might provide an alternative for remote natural gas locations. In this report, we ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)In catalysts for CO2 hydrogenation, the interface between metal nanoparticles (NPs) and the support material is of high importance for the activity and reaction selectivity. In Pt NP-containing UiO Zr-metal–organic frameworks ...
-
(Doctoral thesis / Doktoravhandling, 2013)The main aim of this Ph.D. project was to study, understand and improve the current knowledge on the Cu-based catalytic reaction in the conversion of ethylene-to-1,2-dichloroethane (oxychlorination), a crucial intermediate ...
