High performance and toxicity assessment of Ta3N5 nanotubes for photoelectrochemical water splitting (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In this work, Co-based cocatalysts are electrodeposited on mesoporous Ta3N5 nanotubes. The electrodeposition time is varied and the optimized photoelectrode reaches a photocurrent density of 6.3 mA/cm2 at 1.23 V vs. SHE, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We performed a systematic study involving simulation and experimental techniques to develop induced-junction silicon photodetectors passivated with thermally grown SiO2 and plasma-enhanced chemical vapor deposited (PECVD) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Amorphous thin films of FePO4 and Fe4(P2O7)3 show excellent power capabilities and good stability as cathode materials in Li-ion batteries. Within our tested range of materials, 10 nm FePO4 shows the best results and can ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)The conductivity and Seebeck coefficient of CaMnO3−δ have been studied at temperatures up to 1000 °C and in atmospheres with controlled oxygen partial pressure. Both transport coefficients were varied in situ by the ...
-
High versus low energy ion irradiation impact on functional properties of PLD-grown alumina coatings (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)It is well known that ion irradiation can be successfully used to reproduce microstructural features triggered by neutron irradiation. Even though the irradiation process brings many benefits, it is also associated with ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Coeval pseudotachylytes (solidified melts produced during seismic slip) and mylonites are generally regarded as the geological record of transient seismic events during dominant ductile flow. Thermal runaway has been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The application of double perovskite cobaltites BaLnCo2O6−δ (Ln = lanthanide element) in electrochemical devices for energy conversion requires control of their properties at operating conditions. This work presents a study ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Mixed oxide hydride anion systems constitute a novel class of materials exhibiting intriguing properties such as solid-state hydride ion conduction and fast anion exchange. In this contribution we derive the kinetics of ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Conversion of CO2 into light olefins is an effective strategy for sustainable utilization of fossil energy and biomass. However, highly selective production of specific olefin, such as ethene, from CO2 hydrogenation is a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Process-based rockfall simulation models attempt to better emulate rockfall dynamics to different degrees. As no model is perfect, their development is often accompanied and validated by the valuable collection ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Selective hydrogenation of CO2 into value-added hydrocarbons, particularly single products, is of great interest. However, this is a challenge because of the simultaneous occurrence of numerous competing elementary reactions. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Using first-principles calculations based on density functional theory, we study the magnetic and electronic properties of hole-doped two-dimensional InSe. Our simulations reveal that although 2D InSe is intrinsically ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract The Mourne Mountains magmatic center in Northern Ireland consists of five successively intruded granites emplaced in the upper crust. The Mourne granite pluton has classically been viewed as a type ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The question “what arrests an earthquake rupture?” sits at the heart of any potential prediction of earthquake magnitude. Here, we use a one-dimensional, thin-elastic-strip, minimal model, to illuminate the basic physical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)While of paramount importance in material science, the dynamics of cracks still lacks a complete physical explanation. The transition from their slow creep behavior to a fast propagation regime is a notable key, as it leads ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The oxidation of ammonia is a key reaction for the production of artificial fertilizers and for environmental protection. Depending on the area of application, the catalytic reaction needs to be tuned toward the production ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Human papillomavirus (HPV) 16 and 18 are the most predominant types in cervical cancer. Only a small fraction of HPV infections progress to cancer, indicating that additional factors and genomic events contribute to the ...
