NTNU-SINTEF SolarNet: A solar irradiation monitoring network at high latitudes
(Peer reviewed; Journal article, 2023)This study presents a monitoring network for solar irradiation at high latitudes, called NTNU-SINTEF SolarNet. The network collects, with a time resolution ranging from seconds to hours, solar irradiance data, e.g. global ... -
Empowering CO2 Eco-Refrigeration with Colossal Breathing-Caloric-Like Effects in MOF-508b
(Peer reviewed; Journal article, 2023)Today, ≈20% of the electric consumption is devoted to refrigeration; while, ≈50% of the final energy is dedicated to heating applications. In this scenario, many cooling devices and heat-pumps are transitioning toward the ... -
Exchanging Replicas with Unequal Cost, Infinitely and Permanently
(Peer reviewed; Journal article, 2022)We developed a replica exchange method that is effectively parallelizable even if the computational cost of the Monte Carlo moves in the parallel replicas are considerably different, for instance, because the replicas run ... -
Two-dimensional altermagnets: Superconductivity in a minimal microscopic model
(Peer reviewed; Journal article, 2023)We propose a minimal toy model for a two-dimensional altermagnet. The model unravels altermagnetic properties at a microscopic level. We find spin-split electron and nondegenerate magnon bands with a d -wave symmetry. We ... -
Real-time prediction of fish cage behaviors under varying currents using deep neural network
(Chapter, 2023)This paper presents a Deep Neural Network (DNN) model for rapid and low-cost prediction of fish cage behavior under varying currents. We employ a numerical model of the fish cage created in Orcaflex and a set of current ... -
Data for characterization of the optical properties of Atlantic salmon (Salmo salar) blood
(Peer reviewed; Journal article, 2023)Photoplethysmography is a recent addition to physio-logging in Atlantic salmon which can be used for pulse oximetry provided that the properties for light propagation in salmon tissues are known. In this work, optical ... -
CO<inf>2</inf> capture by 1-ethyl-3-methylimidazolium acetate: Solubility at low pressure and quantification of chemisorption and physisorption
(Peer reviewed; Journal article, 2021)Although chemisorptive ionic liquids (ILs) are widely expected as promising CO2 absorbents, rigorous thermodynamic analyses for such systems remain challenging due to the inevitable co-existence of chemisorption and ... -
An integrated materials approach to ultrapermeable and ultraselective CO2 polymer membranes
(Peer reviewed; Journal article, 2022)A challenge in the design of polymeric membranes for gas separation is the tradeoff between permeability, or how fast gases can flow through the membrane, and selectivity, the ability to separate one gas from another. In ... -
CO2 capture and utilization by biocatalytic synthesis of carboxylic acids: a process design study
(Peer reviewed; Journal article, 2024)The search for less energy-intensive processes is pushing toward a diversification of Carbon-Capture and Utilization/Sequestration (CCU/S) pathways. Biocatalytic processes offer sustainable solutions characterized by ... -
Atomic Structure of Hardening Precipitates in Al-Mg-Si Alloys: Influence of Minor Additions of Cu and Zn
(Peer reviewed; Journal article, 2023)Shifting toward sustainability and low carbon emission necessitates recycling. Aluminum alloys can be recycled from postconsumer scrap with approximately 5% of the energy needed to produce the same amount of primary alloys. ... -
Experimental and theoretical study on efficient CO2 absorption coordinated by molecules and ions of DBN and 1,2,4-triazole formed deep eutectic solvents
(Peer reviewed; Journal article, 2023)Deep eutectic solvents (DESs) as a new class of designer solvents have attracted intensive attention in CO2 capture, while the interactions between CO2 and underlying molecules and/or ions in DESs are poorly understood. ... -
