(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Aerosol–cloud interactions contribute to a large portion of the spread in estimates of climate forcing, climate sensitivity and future projections. An important part of this uncertainty is how much new particle formation ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The increased transport of terrestrially derived organic material (tOM) from catchments to rivers and lakes is leading to browning of northern freshwaters.(1) Although the same environmental drivers can be expected to lead ...

Importance of Val567 on heme environment and substrate recognition of neuronal nitric oxide synthase (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Nitric oxide (NO) produced by mammalian nitric oxide synthases (mNOSs) is an important mediator in a variety of physiological functions. Crystal structures of mNOSs have shown strong conservation of the active‐site residue ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)2-Aminobiphenyl palladacycles are among the most successful precatalysts for Pd-catalyzed cross-coupling reactions, including aryl amination. However, the role of NH-carbazole, a byproduct of precatalyst activation, remains ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In a solid-liquid dual-phase CO2 separation membrane, the native ions in the molten alkali carbonate, including carbonate anions and metal cations can transport CO2 in a process that is charge-compensated by electronic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Disorder-induced formation of metastable Ga2O3 polymorphs as well as the recovery of the stable state upon annealing attract attention because of the fundamental novelty and rapidly increasing interest in the use of Ga2O3 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Mimicking natural photosynthesis by direct photoelectrochemical (PEC) reduction of CO2 to chemicals and fuels requires complex cell assemblies with limitations in selectivity, efficiency, cost, and stability. Here, we ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Molybdenum disulphide (MoS2) is a rising star among transition-metal dichalcogenides in photovoltaics, diodes, electronic circuits, transistors and as a photocatalyst for hydrogen evolution. A wide range of MoS2 polymorphs ...
-
(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, 2022)As temperatures decrease in autumn, vegetation of temperate and boreal ecosystems increases its tolerance to freezing. This process, known as hardening, results in a set of physiological changes at the molecular level that ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Environmental effects of microplastic are rather due to their adsorption capacity of contaminants than themselves. Aging is a key factor influencing adsorption properties of environmental microplastics. In order to clarify ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Ion implantation is an important technique in semiconductor processing and has become a key technology for 4H-SiC devices. Today, aluminum (Al) implantations are routinely used for p-type contacts, p+-emitters, terminations ...
