Micro-lensed negative-curvature fibre probe for raman spectroscopy
(Peer reviewed; Journal article, 2021)We developed a novel miniature micro-lensed fibre probe for Raman spectroscopy. The fibre probe consists of a single negative-curvature fibre (NCF) and a spliced, cleaved, micro-lensed fibre cap. Using a single NCF, we ... -
Micro-lensed optical fibers for a surface-enhanced Raman scattering sensing probe
(Journal article; Peer reviewed, 2018)We present the fabrication and characterization of a novel sensing configuration based on surface-enhanced Raman scattering (SERS) and two micro-lensed optical fibers. The first micro-lensed fiber is used to excite surface ... -
Micro-Nano enhanced surfaces for investigation of oil-water separation
(Master thesis, 2015)Separator are an important part of the oil processing. The fluid mixture extracted from an oil well contains large amount of water, and is separated by using large separators. A gravitational separator relies on the ... -
Micro-Oscillations in Seismic Signals - An Investigation Into Possible Multi-Bubble Origins
(Master thesis, 2018)Since its first use in the early 20th century, seismic acquisition has become the most utilised method of marine hydrocarbon exploration. At its core, the method relies upon pressure imbalances between a bubble of pressurised ... -
Micro-Photoluminescence Spectroscopy of Au-assisted MBE Grown AlGaAs Nanowires with Axial GaAs Inserts
(Master thesis, 2012)AlGaAs nanowires (NWs) with axial GaAs inserts, grown with molecular beam epitaxy will be investigated with micro-photoluminescence spectroscopy, including CW and pulsed excitation at cryogenic and ambient temperatures. -
Micro-photoluminescence spectroscopy of self-catalyzed zincblende GaAs nanowires grown by molecular beam epitaxy
(Master thesis, 2012)In this thesis, single zincblende GaAs nanowires grown by molecular beam epitaxy using the self-catalyzed approach were studied with m-photoluminescence spectroscopy in order to assess the optical quality of self-catalyzed ... -
Micro-scale studies of microbialinduced carbonate precipitation for the application of biocementation
(Doctoral theses at NTNU;2021:59, Doctoral thesis, 2021)Cement, which is used as a binding material in conventional concrete, is the second most consumed material by humans, after water. The production process of cement, however, causes a high emission of CO2 and contributes ... -
Micro-Testing While Drilling for Rate of Penetration Optimization
(Chapter, 2020)The Rate of Penetration (ROP) is one of the key parameters related to the efficiency of the drilling process. Within the confines of operational limits, the drilling parameters affecting the ROP should be optimized to drill ... -
Micro-Testing While Drilling for Rate of Penetration Optimization: Experiments and Simulations
(Peer reviewed; Journal article, 2021)The rate of penetration (ROP) is one of the key parameters related to the efficiency of the drilling process. Within the confines of operational limits, the drilling parameters affecting the ROP should be optimized to drill ... -
Microaggressions
(Chapter, 2023)The conceptualisation of microaggressions has served to create an awareness of the ways in which institutional racism and coloniality continue to surface in daily life in Western institutions of higher education. In light ... -
Microalgae production with rotating algal biofilm reactors for water treatment in land-based fish farms
(Bachelor thesis, 2020)Et denitrifiseringsfilter kan ansees som et lite bærekraftig alternativ til vannbehandling i landbaserte fiskeoppdrettsanlegg siden det ikke tar vare på organiske nitrogenforbindelser som er verdifulle i for eksempel ... -
Microarrays for High Throughput Analysis of Cellular Heterogeneity
(Master thesis, 2017)The importance of cellular heterogeneity within cell populations has been increasingly realized in recent years. As a result, there has been a focus on developing methods for single cell analysis. µCP represents a cheap, ... -
Microarrays for the study of compartmentalized microorganisms in alginate microbeads and (W/O/W) double emulsions
(Journal article; Peer reviewed, 2016)Understanding of cells has mainly been achieved through analysis of average properties of large cellular populations. The increased awareness of cellular heterogeneity in various biological systems, spans from single ... -
Microbial challenges in recirculating aquaculture systems (RAS) for Atlantic salmon (Salmo salar) smolt and post-smolt
(Doctoral thesis, 2021)Aquaculture is one of the fastest growing food producing sectors today. Norway is the world’s largest producer of farmed Atlantic salmon (Salmo salar), and the aquaculture industry is an important contributor to value ... -
Microbial characterization and influence on copepod (Acartia tonsa) nauplii and egg production in water treatment systems with and without membrane filtration
(Master thesis, 2014)Acartia tonsa is a pelagic calanoid copepod with a diverse distribution, a wide tolerance of temperature and salinities, has short generation time, can produce resting eggs, and has been considered as an excellent feed for ... -
Microbial communities in seawater from an Arctic and a temperate Norwegian fjord and their potentials for biodegradation of chemically dispersed oil at low seawater temperatures
(Journal article; Peer reviewed, 2018)Biodegradation of chemically dispersed oil at low temperature (0–2 °C) was compared in natural seawater from Arctic (Svalbard) and a temperate (Norway) fjords. The oil was premixed with a dispersant (Corexit 9500) and ... -
Microbial community analysis in developing biogas reactor technology for Norwegian agriculture
