Study of Aggregation of Tetrameric Acid and its Interaction with Crude Oil Asphaltenes by Isothermal Titration Calorimetry
(Master thesis, 2013)Tetrameric acids, also called Arn, are a family of molecules present in crude oils and responsible for formation of deposits by reaction with calcium ions. These deposits are detrimental to oil production and therefore the ... -
A Study of Bubble Behavior and Anode Effect on the Graphite and Industrial Carbon Anode in a See-Through Furnace During Aluminium Electrolysis
(Peer reviewed; Journal article, 2022)Anode gas bubble behavior and anode effect on graphite and industrial carbon rod-shaped anode in a cryolite melt have been studied using a see-through furnace. The different carbon materials have different properties which ... -
Study of controllable inclusion addition methods in Al melt
(Journal article; Peer reviewed, 2019)Ceramic Foam Filtration (CFF) is a widely used technique to remove inclusions from Al melt. To ensure sufficient inclusions in the melt during the grain refiners/filtration interaction, inclusion addition methods, such as ... -
Study of Desorption of Asphaltene from Solid Surface by Use of Solvents and Chemicals
(Master thesis, 2015)A study of adsorption and desorption of asphaltene on a stainless steel surface was preformed. A quartz crystal microbalance (QCM) was used for the the study. Different solvents were tested for their ability to desorb ... -
A study of eddy current field interactions in ferromagnetic / normal metal thin film structures and its impact on ferromagnetic resonance
(Master thesis, 2015)This study investigates the eddy current field interaction in ferromagnetic (FM) / normal-metal (NM) thin film structures and its impact on ferromagnetic resonance (FMR). Eddy currents correspond to circulating currents ... -
Study of FeSi Interlayers Formed During Iron-Mediated Epitaxial Growth of Graphene on SiC Substrates
(Master thesis, 2016)A proposed graphene integrated semiconductor radiation sensor takes advantage of the electric field effect in graphene by measuring the change in resistance as a function of radiation exposure to the semiconductor substrate. ... -
Study of genes Avin5390 and Avin30120's effect on encystment properties in Azotobacter vinelandii
(Master thesis, 2019)Azotobacter vinelandii har den uvanlige evnen å gå inn i et metabolsk nedregulert stadie kalt en cyste. Cellen stopper de fleste metabolske aktiviteter og dekker seg selv med to beskyttende lag som forbedrer cellens ... -
Study of HIPP25, HIPP26, HIPP27 gene expression and glucosinolate content in Arabidopsis thaliana and Noccaea caerulescens upon heavy metal treatments
(Master thesis, 2017)Hyperaccumulator plant species accumulate exceedingly high concentrations of metals in aerial parts and are increasingly studied because of their potential for cleaning up land contaminated with heavy metals. One such ... -
