Amino-Functionalized Magnetic Nanoparticles for Extraction of Naphthenic Acids
Strand, Mikael (Master thesis, 2016)The present work is a part of a 2-year Post Doc project carried out by a Vista program funded by Statoil and conducted in close collaboration with The Norwegian Academy of Science and Letters. The goal of the main project ... -
Chemical Modification of Microfibrillated Cellulose: Effects on Film Barrier Properties
Rodionova, Galina (Doktoravhandlinger ved NTNU, 1503-8181; 2011:303, Doctoral thesis, 2011)A global demand for environmental sustainability is a strong driving force towards the development of enhanced barrier concepts and the use of new materials, especially for packaging applications. Abundant and renewable, ... -
Droplet Crystallization in Water-in-Crude Oil Emulsions: Influence of Salinity and Droplet Size
Kolotova, D.; Brichka, K.; Rodionova, Galina; Simon, Sebastien Charles; Derkach, S.; Paso, Kristofer Gunnar; Sjøblom, Johan (Journal article; Peer reviewed, 2017)Ice crystallization in confined spherical geometries is investigated experimentally at ambient pressure conditions. Water-in-crude (w/o) oil emulsions are formed by homogenization of an acidic North Sea crude oil with water ... -
Kinetics of Crystallization of Aqueous Droplets in Water-in-Crude Oil Emulsions at Low Temperatures
Derkash, S. R.; Kolotova, D.; Rodionova, Galina; Simon, Sebastien Charles; Sjøblom, Johan; Andrianov, A. V.; Malkin, A.Ya. (Journal article; Peer reviewed, 2018)This study focused on the examination of the isothermal crystallization of aqueous droplets in water-in-crude oil emulsions with water concentrations in the range of 5 to 20 wt %. Experiments were carried out using ... -
Magnetic Nanoparticles for Extraction of Naphthenic Acids from Model Oil
Ronander, Mia Elise (Master thesis, 2015)The Master s thesis aims for synthesis of magnetic nanoparticles (MNP), silica-coated magnetic nanoparticles, and their application for extraction of naphthenic acids (NA) from model oil. The present work is a part of a ... -
Polyethyleneimine-coated magnetic iron oxide nanoparticles for improvement of flow assurance
Fyllingsnes, Regina Lopez (Master thesis, 2017)This thesis aims to gain further insight into how the naphthenic acids (NA), which cause different problems with respect to flow assurance, can be removed from the water phase. The main objective has been to test how ... -
Potential applications of magnetic nanoparticles within separation in the petroleum industry
Rodionova, Galina; Strand, Mikael; Øye, Gisle (Journal article; Peer reviewed, 2018)Magnetic nanoparticles have unique properties such as extremely large surface area per volume substance and strong magnetic response. In addition, the possibilities for surface functionalization make them exciting candidates ... -
The formation and characterization of sustainable layered films incorporating Microfibrillated Cellulose (MFC)
Rodionova, Galina; Roudot, Solenne; Eriksen, Øyvind; Männle, Ferdinand; Gregersen, Øyvind Weiby (Journal article; Peer reviewed, 2012)Microfibrillated cellulose (MFC), TEMPO-pretreated MFC, and hybrid polymer/MFC mix were used for the production of layered films with interesting properties for application in food packaging. The series of samples were ...
