Iron oxide nanocrystals clustered in oil-in-water nanoemulsions: Preparation, characterization, and transverse relaxivities
(Master thesis, 2015)Iron oxide nanocrystals (IONCs) have attracted extensive interest due to their high magnetization that efficiently decreases the transverse relaxation times of water protons. The increase in their transverse relaxivities ... -
Iron related precipitates in multicrystalline silicon by conductive atomic force microscopy
(Peer reviewed; Journal article, 2021)Multicrystalline silicon (mc-Si) is a widely used material for photovoltaic applications. The presence of metallic contaminated grain boundaries strongly affects the crystal electronic properties enhancing electron-hole ... -
Iron separation from bauxite through smelting reduction
(Master thesis, 2019)containing slag. Sammendrag Alumina produksjon domineres kommersielt av Bayer-prosessen som også produserer rødslam. Dette kan ikke forbrukes og foråsaker store skader på miljøet. Et bærekraftig alternativ for bearbeiding ... -
Iron Separation from Bauxite Through Smelting-Reduction Process
(Chapter, 2017)In the alumina production process through the dominant commercial Bayer process red mud, which is not consumable and causes serious environmental challenges is produced. Alternative sustainable process for bauxite treatment ... -
Iron Speciation and Physiological Analysis Indicate that Synechococcus sp. PCC 7002 Reduces Amorphous and Crystalline Iron Forms in Synthetic Seawater Medium
(Peer reviewed; Journal article, 2020)Cyanobacteria have high iron requirements due to iron-rich photosynthetic machineries. Despite the high concentrations of iron in the Earth’s crust, iron is limiting in many marine environments due to iron’s low solubility. ... -
Iron supported on beaded carbon black as active, selective and stable catalyst for direct CO<inf>2</inf> to olefin conversion
(Journal article; Peer reviewed, 2023) -
Iron Uptake in the Cyanobacteria Synechococcus sp. PCC7002
(Master thesis, 2017)In this project I will explore iron uptake in the cyanobacterium Synechococcus 7002 sp. Particularly in terms of of siderophore production, in addition to the iron transport complex FutABC. The methods employed will be a ... -
Iron-Mediated Growth of Graphene on SiC for Radiation Detection
(Master thesis, 2017)A proposed radiation sensor exploits graphene's high electron mobility and sensitivity to miniscule electric fields to attain a novel approach for radiation detection. Realizing such a sensor is contingent on controlled ... -
Is ambient light during the high Arctic polar night sufficient to act as a visual cue for zooplankton?
(Journal article, 2015)The light regime is an ecologically important factor in pelagic habitats, influencing a range of biological processes. However, the availability and importance of light to these processes in high Arctic zooplankton communities ... -
Is basal metabolic rate associated with recruit production and survival in free-living house sparrows?
(Journal article; Peer reviewed, 2016)Life history theory predicts that available energy is limited and needs to be allocated among different processes such as growth, reproduction and self-maintenance. Basal metabolic rate (BMR), a common measure of an animal's ... -
Is dehulling of peas and faba beans necessary prior to dry fractionation for the production of protein- and starch-rich fractions? Impact on physical properties, chemical composition and techno-functional properties
(Journal article; Peer reviewed, 2020)Dehulling of peas and faba beans prior to milling and air classification was evaluated, namely its impact on physical properties, chemical composition and techno-functional properties of the fractions. Dry fractionation ... -
Is it possible to escape from a crocodile attack? Review of human and saltwater crocodile conflict in Asia in Australia
(Master thesis, 2022)Human and saltwater crocodile conflict has been increasing yearly in crocodile-inhabited countries in Asia and Australia. This study was conducted to foster the safety of humans and the wellbeing of saltwater crocodiles, ... -
Is literature data useful for identifying enzyme catalysts for new substrates? A case study on reduction of 1-aryl-2-alkanoates
(Journal article; Peer reviewed, 2017)The use of literature data to identify catalysts for a novel transformation is a commonly used approach. Herein, we have evaluated if this is a viable strategy in enzyme catalysis, using asymmetric reduction of 1-aryl-2-alkanoates ... -
