Effect on cycle life with different pre-lithiation depths of silicon anode in Si/LFP full cell
(Master thesis, 2023)This study examines the impact of various pre-lithiation conditions on the cycling performance of a Silicon (Si) anode in Li-ion batteries (LIBs). A commercially available Si active material was utilized, and CR2032-type ... -
Effects of confinement pressure on the mechanical behavior of an oil well cement paste
(Peer reviewed; Journal article, 2021-11)Oil well cement paste is a key structural component in wells that should provide mechanical support to the casing and prevent uncontrolled flow of formation fluids along the wellbore and to the environment. Since the annular ... -
Effects of Nanoparticles (Al2O3 and TiO2), Fibers and Fly Ash on Cementitious and Non-cementitious Materials at Room Temperature and 80°C Curing Temperature: Experimental and Empirical Modelling Studies
(Master thesis, 2022)Cement constitutes undoubtedly one of the most important well barrier elements, in terms of maintaining well integrity by preventing undesired flow of reservoir fluid into the wellbore. NORSOK D-010 standard dictates that ... -
Effects of polymer adsorption on the effective viscosity in microchannel flows: phenomenological slip layer model from molecular simulations
(Journal article; Peer reviewed, 2018-10)Molecular simulations (Dissipative Particle Dynamics - DPD) were used to quantify the effect of polymer adsorption on the effective shear viscosity of a semi-dilute polymer solution in microchannel Poseuille flow. It is ... -
Effects of Potential Determining Ions and pH on the Wettability of Intermediate Wet Outcrop Limestone
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-13)The intent of this study is to determine if the wettability of slightly oil wet limestone can be shifted toward water wet using “Smart Water”. The theory of “Smart Water” in carbonates proposes that increasing the composition ... -
Effekt av SiO2 nanopartikler og Kvarts mikropartikler på den nylig formulerte geopolymeren: Eksperimentelle og modelleringsstudier
(Bachelor thesis, 2023)I olje- og gassindustrien brukes sement som en brønnbarrierekomponent. Studier av brønnintegritet på produksjons- og injeksjonsbrønner i Nordsjøen har vist at omtrent 11% av integritetsfeilene er relatert til sement. Dette ... -
