Reactivity and Synergism of Vanadium in Microporous Supports with Copperas a Co-cation
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:213, Doctoral thesis, 2014)This study investigates three-dimensional (3-D) microporous materials as carrier systems for vanadium species for the oxidation of propene, also examining the effect of copper as a co-cation.Various 3-D systems have been ... -
Reactivity of Anode Raw Materials and Anodes for Production of Aluminium
(Dr. ingeniøravhandling, 0809-103X; 2001:117, Doctoral thesis, 2002)In the Hall-Héroult process for primary production of aluminium, a considerable amount of anode carbon is lost through unwanted gasification in air and CO2. The carbon gasification reactions are catalyzed by a number of ... -
Real-time coupled-cluster approaches for electronic multiphoton processes in atoms and molecules
(Doctoral theses at NTNU;2023:227, Doctoral thesis, 2023)This thesis explores time-dependent coupled cluster (TDCC) and time-dependent equation-of-motion coupled cluster (TD-EOM-CC) methods in quantum chemistry. As part of the thesis work, these methods were integrated into the ... -

Recycling of paper, cardboard and its PFAS in Norway
(Peer reviewed; Journal article, 2023)Per- and polyfluoroalkyl substances (PFAS) have been used in paper products since the 1960s. PFAS emissions during the life cycle of these products have been substantial sources of these substances to the environment. Here, ... -
Reduced orbital space coupled cluster calculations using a multilevel Hartree-Fock wave function
(Master thesis, 2017)Embedding, or multilevel, schemes have become exceedingly popular in recent years. The idea is to divide the system into an active part, which is treated by an accurate quantum mechanical method, and then treat the rest ... -
