Synthetic Efforts to Investigate the Effect of Planarizing the Triarylamine Geometry in Dyes for Dye-Sensitized Solar Cells
(Peer reviewed; Journal article, 2022)The geometry of a dye for dye-sensitized solar cells (DSSCs) has a major impact on its optical and electronic properties. The dye structure also dictates the packing properties and how well the dye insulates the metal–oxide ... -
Pinpointing basic sites formed upon incorporation of iron in hierarchical SAPO-11 using catalytic model reactions
(Peer reviewed; Journal article, 2022)By utilizing previously established catalytic model reactions, a method for probing the topological location of transition metal sites incorporated in hierarchical silicoaluminophosphates (SAPOs) is presented. For the first ... -
Exploring the effects of approach velocity on depletion force and coalescence in oil-in-water emulsions
(Journal article; Peer reviewed, 2021) -
Alginate gels crosslinked with chitosan oligomers - a systematic investigation into alginate block structure and chitosan oligomer interaction
(Peer reviewed; Journal article, 2021)Three alginates with fundamentally different block structures, poly-M, poly-G, and poly-MG, have been investigated upon ionic crosslinking with chitosan oligosaccharides (CHOS), using circular dichroism (CD), rheology, and ... -
On the value of popular crystallographic databases for machine learning prediction of space groups
(Peer reviewed; Journal article, 2022)Predicting crystal structure information is a challenging problem in materials science that clearly benefits from artificial intelligence approaches. The leading strategies in machine learning are notoriously data-hungry ... -
One-dimensional mathematical modeling of two-phase ejectors: Extension to mixtures and mapping of the local exergy destruction
(Peer reviewed; Journal article, 2022)The ejector is a process equipment frequently used in refrigeration processes. There is currently a knowledge gap on the efficiency of ejectors operating with mixtures. To address this knowledge gap, we present a one-dimensional ... -
Synthesis of Hierarchical Metal Incorporated Zeotypes Isomorphous substitution of copper and iron into CHA and AFI topologies
(Doctoral theses at NTNU;2023:14, Doctoral thesis, 2023)The goal of the work in this dissertation is to synthesize catalysts needed for a greener future in which we utilize our limited resources more sustainably. In particular, the work focuses on the creation of isomorphous ... -
Getting in control of persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances to protect water resources: strategies from diverse perspectives
(Peer reviewed; Journal article, 2022)Background Safe and clean drinking water is essential for human life. Persistent, mobile and toxic (PMT) substances and/or very persistent and very mobile (vPvM) substances are an important group of substances for which ... -
Determination of the Oxidative Stress Biomarkers of 8-Hydroxydeoxyguanosine and Dityrosine in the Gills, Skin, Dorsal Fin, and Liver Tissue of Atlantic Salmon (Salmo salar) Parr
(Peer reviewed; Journal article, 2022)Oxidative stress is a condition caused by an imbalance in the occurrence of reactive oxygen species in the cells and tissues of organisms. An ultra-performance liquid chromatography–electrospray ionization tandem mass ... -
Maternal phthalate urine concentrations, fetal growth and adverse birth outcomes. A population-based prospective cohort study
(Peer reviewed; Journal article, 2021)Importance Exposure to phthalates may affect fetal growth, but previous studies are inconsistent and have not explored the trimester-specific effects of phthalates on repeated measures of fetal growth. Objective To ... -
Prenatal exposure to nonpersistent chemical mixtures and fetal growth: A population-based study
