(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Protein methylation occurs primarily on lysine and arginine, but also on some other residues, such as histidine. METTL18 is the last uncharacterized member of a group of human methyltransferases (MTases) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)We present a comprehensive investigation of the structural, electronic, mechanical, and optical properties of four promising candidates, namely Au2Cs2I6, Ag2GeBaS4, Ag2ZnSnS4, and AgCuPO4, for application in photovoltaic ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Elasto-plastic fracture toughness tests of a commercially pure iron were performed in air and in hydrogen gas at two different pressures. Some unique characteristics of hydrogen-enhanced cracking were exhibited at both the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Hydrogen (H) is thought to be strongly involved in the light and elevated temperature-induced degradation observed predominantly in p-type silicon wafers, but the nature of the defect or defects involved in this process ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Metal–organic frameworks (MOFs) show great prospect as catalysts and catalyst support materials. Yet, studies that address their dynamic, kinetic, and mechanistic role in target reactions are scarce. In this study, an ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)With the increasing demand for green energy, there is a great urgency to develop perm-selective, economical and robust membranes for applications in fuel cells. Metal–organic frameworks are attractive materials for this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The ability to achieve highly resistive beta-phase gallium oxide (β-Ga2O3) layers and substrates is critical for β-Ga2O3 high voltage and RF devices. To date, the most common approach involves doping with iron (Fe), which ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2022)Surface treatment after dry etching is vital to enhance the surface quality of the material and thus improve device performance. In this Letter, we identified the majority surface states induced by the dry etching of β-Ga2O3 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Photoelectron spectroscopy is a powerful characterisation tool for semiconductor surfaces and interfaces, providing in principle a correlation between the electronic band structure and surface chemistry along with quantitative ...
-
(Chapter / Bokkapittel / SubmittedVersion, 2021)High-Entropy Alloys are advanced technological materials composed of several (typically five) elements in nearly equal atomic concentration. By forming these alloys, previously unknown phase fields of multidimensional phase ...
