Assessing the surface sites of the microporous materials H-ITQ-7 and H-Beta using FT-IR spectroscopy and various molecular probes
Skorpa, Ragnhild (Master thesis, 2010)The aim of the work presented in this thesis was to synthesize and assess the surface sites of two possible acid catalysts. The MTH reaction was used as a model reaction to evaluate the possibilities for the materials to ... -
Equilibrium properties of the reaction H2=2H by classical molecular dynamics simulations
Skorpa, Ragnhild; Simon, Jean-Marc; Bedeaux, Dick; Kjelstrup, Signe (Journal article; Peer reviewed, 2014)We have developed a classical molecular dynamics model for the hydrogen dissociation reaction, containing two- and three-particle potentials derived by Kohen, Tully and Stillinger. Two fluid densities were investigated for ... -
Hydrogen dissociation under equilibrium and non-equilibrium conditions A study using molecular dynamics
Skorpa, Ragnhild (Doctoral thesis at NTNU;2014:323, Doctoral thesis, 2014)The aim of this thesis project was to model reactions using classical molecular dynamics simulations under both equilibrium and non-equilibrium conditions and to study the effect of the reaction on the transport properties ... -
Properties of Dense Barite Sediments from Water-Based Drilling Fluids Oscillatory Viscosity Measurements of Wet Barite Powder
Werner, Benjamin; Pedrosa, Camilo; Skorpa, Ragnhild; Ytrehus, Jan David; Vrålstad, Torbjørn; Saasen, Arild (Journal article; Peer reviewed, 2021) -
Simulation of fluid flow through real microannuli geometries
Corina, Anisa Noor; Skorpa, Ragnhild; Sangesland, Sigbjørn; Vrålstad, Torbjørn (Journal article; Peer reviewed, 2020)Debonding of well cement towards casing or rock, i.e. microannuli formation, is a typical failure mode of cement barriers. Consequently, such microannuli may act as leak paths during leakages of downhole fluids such as ...
