Integrative Systems Biology Approaches for Analyzing High-Throughput Data Applications to modeling of gene regulatory networks
(Doctoral thesis at NTNU;2015:68, Doctoral thesis, 2015)Systems biology is relatively new and interdisciplinary field developed to study and understand the complex behavior of biological systems at systems level rather than at its individual elements. This is achieved by ... -
Interaction between asphaltenes and fatty-alkylamine inhibitor in bulk solution
(Journal article; Peer reviewed, 2018)In the present work, the mechanism of interaction between asphaltenes and a commercial fatty-alkylamine inhibitor was investigated by a combination of techniques. The “macro” properties, like the asphaltene precipitation ... -
Interaction of different crude oils with model shoreline surfaces: Adsorption and wettability studies
(Master thesis, 2013)To improve shoreline cleanup operations in the current oil spill response systems, a better understanding of the interactions between the spilled crude oil and the shoreline surfaces is required. The objective of this study ... -
Interaction of hydrogen with flat (0001) and corrugated (11–20) and (10–12) cobalt surfaces: Insights from experiment and theory
(Journal article; Peer reviewed, 2019)Cobalt catalysts are used on a commercial scale to produce synthetic fuels via the Fischer-Tropsch synthesis process. As adsorbed hydrogen atoms are involved in many of the elementary reaction steps that occur on the ... -
Interactions between Asphaltenes and a Model Demulsifier in Bulk and at an Interface Studied by Small-Angle Neutron Scattering (SANS) and Neutron Reflectometry
(Peer reviewed; Journal article, 2020)This article describes neutron reflectometry to probe the structure of the asphaltene layer adsorbed onto a hydrophilic silicon surface and the interactions between asphaltenes and a model demulsifier (pluronic). To start ... -
Interactions between Surfactants and Cellulose Nanofibrils for Enhanced Oil Recovery
(Journal article; Peer reviewed, 2018)Chemical enhanced oil recovery (EOR) represents a series of potential solutions for extracting more oil from resources with already known locations and magnitudes. Unfortunately, many of the chemical additives in use today ... -
