Cost Optimality of Energy Systems in Zero Emission Buildings in Early Design Phase
(Master thesis, 2013)The building sector accounts for a significant proportion of industrial countries total energy use, thus a cut in this sector has been regarded necessary to reach future climate goals. An important measure in this context ... -
Cost-effective electrodes for alkaline water electrolysis
(Doctoral theses at NTNU;2022:16, Doctoral thesis, 2022)Green hydrogen production using water electrolysis has potential to be the key component in storing and coupling renewable energy to the transportation and chemical sectors. Alkaline water electrolysis offers a relatively ... -
Cost-efficient core-shell TS-1/silicalite-1 supported Au catalysts: Towards enhanced stability for propene epoxidation with H2 and O2
(Journal article; Peer reviewed, 2018)Designing cost-effective TS-1 with enhanced catalytic stability in direct propene epoxidation with H2 and O2 is attracting tremendous research interests. In this work, a novel hydrophobic TS-1/S-1 lamellar support with ... -
Costs and benefits associated with natural resource exploitation in Chatthin Wildlife Sanctuary in Myanmar, and its impact on thamin (Rucervus eldii thamin) conservation
(Master thesis, 2017)The conservation of wildlife in the Anthropocene inevitably depends on an understanding of how human populations interact with wildlife and its habitat. This involves understanding (1) how they exploit the natural resources ... -

Coupled Cluster for High-Spin Open-Shell Systems - A Mixed Orbital Approach
(Master thesis, 2016)The description of high-spin open-shell systems with coupled cluster (CC) theory presents problems not encountered in the closed-shell case. Spin-contamination and additional computational cost compared to closed-shell ... -
Coupled cluster investigations of spectroscopic properties in molecular and crystalline systems
(Doctoral theses at NTNU;2022:343, Doctoral thesis, 2022)Theoretical studies of spectroscopic properties are of great value, both by themselves and in combination with experiments. The highly accurate coupled cluster methods are attractive options for such studies. Due to their ... -
Coupled cluster methods for nonadiabatic molecular dynamics
(Doctoral theses at NTNU;2020:241, Doctoral thesis, 2020)Reliably predicting nuclear dynamics in excited electronic states requires an accurate representation of the involved electronic states. One challenge in this respect is the correct description of electronic degeneracies, ... -
Coupled cluster theory and strong light-matter coupling
(Doctoral theses at NTNU;2023:354, Doctoral thesis, 2023)Chemical properties and reactivity are influenced by many external factors, such as temperature, pressure, solvents, and electric fields. In spectroscopy, molecules are probed using light, which yields information about ... -
Coupled Cluster Theory for Molecular Polaritons: Changing Ground and Excited States
(Peer reviewed; Journal article, 2020)We present an ab initio correlated approach to study molecules that interact strongly with quantum fields in an optical cavity. Quantum electrodynamics coupled cluster theory provides a nonperturbative description of ... -
Coupled Ion Transport in Concentrated PEO-LiTFSI Polymer Electrolytes
(Peer reviewed; Journal article, 2023)Understanding how microscopic mechanisms govern macroscopic transport properties is important for development of improved electrolytes for Li-ion batteries. The archetypal polymer electrolyte PEO–LiTFSI has been investigated ... -
Coupled Transport in Li-ion Battery Electrolytes
(Doctoral theses at NTNU;2024:187, Doctoral thesis, 2024)Electrolytes are materials that contain mobile charge carriers – ions. The electrolyte in lithium-ion batteries enables the transport of positive Li+ ions in between the electrodes during battery operation. The transport ... -
Coupled Transport of Heat, Mass and Charge in Ion Exchange Membranes - Aqueous Chloride Systems Relevant for Harvesting of Low-Grade Waste Heat
(Master thesis, 2018)In this thesis, the theory of classical non-equilibrium thermodynamics is used as a tool for the analysis of transport processes in ion exchange membranes, and for designing experiments for the determination of coupling ... -
Coupled transports of heat and mass at the surface of and inside silicalite
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:266, Doctoral thesis, 2008) The objective of this thesis was to gain a better understanding about the transport of gas and heat across a membrane and to shed light on the coupling effects between heat and mass transfer. As a model ... -
Coupling and competition between ferroelectricity, magnetism, strain, and oxygen vacancies in AMnO3 perovskites
(Journal article; Peer reviewed, 2016)We use first-principles calculations based on density functional theory to investigate the interplay between oxygen vacancies, A-site cation size/tolerance factor, epitaxial strain, ferroelectricity, and magnetism in the ... -
