A Photomagnetic Sponge: High-Temperature Light-Induced Ferrimagnet Controlled by Water Sorption
Magott, Michal; Reczynski, Mateusz; Gawel, Bartlomiej; Sieklucka, Barbara; Pinkowicz, Dawid (Journal article; Peer reviewed, 2018)“Converting” light energy to magnetization is the attribute of molecule-based compounds called photomagnets and is inaccessible for conventional magnetic solids. The design and synthesis of such compounds, however, is a ... -
Characterisation of gas-liquid interfaces related to offshore produced water treatment.: The effect of pH, brine and crude oil composition.
Trapnes, Helle Hofstad (Master thesis, 2013)Produced water is water co-produced with oil and gas during petroleum production. It is a very complex mixture and contains different compounds that can have negative impact on the environments. It is therefore important ... -
Characterisation of Gas-Liquid Interfaces related to Offshore Produced Water Treatment.: The Influence of Crude Oil Composition and different Brines with various pH.
Kløcker, Kaja Neeb (Master thesis, 2013)Produced water is an environmental toxic and complex mixture, which is co-produced during gas and oil production. The aim of this study is to investigate the surface tension of the produced water with a bubble pressure ... -
Characterisation of gas-liquid interfaces related to offshore produced water treatment: Interfacial activity of model components
Hodneland, Solveig (Master thesis, 2013)The amount of produced water during oil production is increasing as oil fields mature. Produced water is the largest source of pollution in the production phase, and can be treated by a method known as gas flotation. To ... -
Characterisation of liquid-liquid interfaces related to offshore produced water treatment - interfacial activity of model Components
Olhaye, Omar (Master thesis, 2013)Produced water is one of the biggest environmental challenges in gas and crude oil production, and the stability of oil in water emulsions makes separation during treatments difficult.The objective of this work is to find ... -
Dynamic wettability alteration for combined low salinity brine injection and surfactant flooding on silica surface
Nourani, Meysam; Tichelkamp, Thomas; Hosseinzade Khanamiri, Hamid; Johansen, Trine; Hov, Ingrid Karlsen; Gawel, Bartlomiej; Torsæter, Ole; Øye, Gisle (Peer reviewed; Journal article, 2020)Experimental results of dynamic contact angle measurements of low salinity brine and combined low salinity water and surfactant flooding (LSW–SF) on silica surface are presented in this study. Dynamic contact angle experiments ... -
Effects of Water Content and Temperature on Bulk Resistivity of Hybrid Cement/Carbon Nanofiber Composites
Gawel, Kamila; Taghipour, Ali; Bjørge, Ruben; Wenner, Sigurd; Gawel, Bartlomiej; Ghaderi, Amir; Cerasi, Pierre (Peer reviewed; Journal article, 2020)Cement nanocomposites with carbon nanofibers (CNFs) are electrically conductive and sensitive to mechanical loads. These features make them useful for sensing applications. The conductive and load sensing properties are ... -
Electrochemical enhancement and inhibition of calcium carbonate deposition
Edvardsen, Laura; Gawel, Kamila; Torsæter, Malin; Gawel, Bartlomiej; Wenner, Sigurd (Peer reviewed; Journal article, 2020)Calcium carbonate is by far the most widespread scaling material. Its deposition in pipes and flowlines has been a long-standing problem for many industries. Hence, a lot of research is devoted to scale inhibition. One of ... -
In situ high temperature spectroscopic study of liquid inclusions and hydroxyl groups in high purity natural quartz
Gawel, Bartlomiej; Ulvensøen, Anna; Lukaszuk, Katarzyna Anna; Muggerud, Astrid Marie Flattum; Erbe, Andreas (Peer reviewed; Journal article, 2021)High purity natural based quartz is used as raw material for production of crucibles for solar-grade silicon production. The crucible properties are strongly related to presence of water and hydroxyl groups in the raw ... -
Interfacial characterisation of dispersed components in produced water
Lesaint, Caterina (Master thesis, 2012)While a number of studies have investigated the processes responsible for the decay of the interfacial tension between crude oil and water with time, there is a great need for an improved understanding of the mechanisms ... -
Modeling of surfactant adsorption on coated quartz crystal surfaces during surfactant flooding process
Nourani, Meysam; Tichelkamp, Thomas; Gawel, Bartlomiej; Norrman, Jens; Øye, Gisle (Peer reviewed; Journal article, 2020)The focus of this study was the experimental determination of surfactant adsorption during low salinity water injection combined with surfactant flooding (LSW-SF) into an oil reservoir and development of an analytical model ... -
Structural evolution of water and hydroxyl groups during thermal, mechanical and chemical treatment of high purity natural quartz
Gawel, Bartlomiej; Ulvensøen, Anna; Lukaszuk, Katarzyna Anna; Arstad, Bjørnar; Muggerud, Astrid Marie Flattum; Erbe, Andreas (Peer reviewed; Journal article, 2020)Fused silica crucibles are commonly used in the fabrication process of solar grade silicon ingots. These crucibles are manufactured from high purity natural quartz sand and as a consequence, their properties are influenced ...
