Can Temperature-Programmed Techniques Provide the Gold Standard for Carbon Surface Characterization?
(Peer reviewed; Journal article, 2022)Due to their chemical and thermal stability, electrical conductivity, and high specific surface areas, nanocarbons and porous carbon materials have found use in numerous key applications within the current transition of ... -
Effect of cobalt promotion on hydrotalcite-derived nickel catalyst for CO2 methanation
(Peer reviewed; Journal article, 2021)A series of cobalt-promoted Ni-Mg-Al hydrotalcite-derived catalysts were tested towards CO2 methanation reaction. The best among examined catalysts was the one with 1 wt% of cobalt in fresh hydrotalcite, obtaining 77% of ... -
On-shell recursion relations for nonrelativistic effective field theories
(Peer reviewed; Journal article, 2021)We derive on-shell recursion relations for nonrelativistic effective field theories (EFTs) with enhanced soft limits. The recursion relations are illustrated through analytic calculation of tree-level scattering amplitudes ... -
Understanding Selectivity in CO2 Hydrogenation to Methanol for MoP Nanoparticle Catalysts Using In Situ Techniques
(Peer reviewed; Journal article, 2021)Molybdenum phosphide (MoP) catalyzes the hydrogenation of CO, CO2 , and their mixtures to methanol, and it is investigated as a high-activity catalyst that overcomes deactivation issues (e.g., formate poisoning) faced by ... -
Experimental Characterization and Modelling of the PLC Effect in an AlMg-Alloy
(Peer reviewed; Journal article, 2021)In the present work, uniaxial tension tests have been conducted to study the mechanical response of a commercial Al4.5wt%Mg alloy (AA5182). The measurements range from the strain rate of 10-4 to 100 s-1 at room temperature. ... -
Evidence of avian influenza virus inseabirds breeding on a Norwegian high-Arctic archipelago
(Peer reviewed; Journal article, 2020)Wild aquatic birds serve as the natural reservoir for avian influenza virus (AIV), a disease with significant implications for avian and mammalian health. Climate change is predicted to impact the dynamics of AIV, particularly ... -
Quantitative and qualitative consequences of reduced pollen loads in a mixed-mating plant
(Journal article; Peer reviewed, 2019)Greater pollination intensity can enhance maternal plant fitness by increasing seed set and seed quality as a result of more intense pollen competition or enhanced genetic sampling. We tested experimentally these effects ... -
Collection of aluminium packaging today
(Research report, 2019)This report investigates the collection of aluminium packaging, particularly in China, the United States and the European Union. A literature search among journal articles using Google Scholar, company and organization ... -
Numerical analysis of boundary conditions in a Lagrangian particle model for vertical mixing, transport and surfacing of buoyant particles in the water column
(Journal article; Peer reviewed, 2019)Lagrangian particle models are used for many applications in the ocean sciences, including transport modelling of oil spills, fish eggs and larvae, plastics, and sediment particles. In the context of oil spill modelling, ... -
Little Ice Age summer temperatures in Western Norway from a 700-year tree-ring chronology
(Journal article; Peer reviewed, 2018)A ring-width Pinus sylvestris chronology from Sogndal in western Norway was created, covering the period AD 1240–2008 and allowing for reconstruction of monthly mean July temperatures. This reconstruction is the first of ... -
Mechanical, thermal and swelling properties of cellulose nanocrystals/PVA nanocomposites membranes
