L-DOPA-Coated Manganese Oxide Nanoparticles as Dual MRI Contrast Agents and Drug-Delivery Vehicles
(Journal article; Peer reviewed, 2016)Manganese oxide nanoparticles (MONPs) are capable of time-dependent magnetic resonance imaging contrast switching as well as releasing a surface-bound drug. MONPs give T2/T2* contrast, but dissolve and release T1-active ... -
L1 Adaptive Anti-Slug Control
(Journal article; Peer reviewed, 2017)In many multiphase pipeline-riser systems, anti-slug control is necessary to ensure steady and optimal operation. In this paper, we propose using an ℒ1 adaptive controller as an augmentation to standard PI control to ... -
Lagrangian Decomposition for Dynamic Real-Time Optimization: Applied to Production Optimization Network
(Master thesis, 2017)The scope of this thesis was to investigate the use of lagrangian decomposition for a dynamic real-time optimization(RTO) problem. The decomposition was performed on a gas lifted two-well network, controlled by a nonlinear ... -
Lagrangian framework for whole fluid particle behavior
(Master thesis, 2024)Denne masteroppgaven introduserer et teoretisk rammeverk designet for å utforske dynamikken til fluide partikler, inkludert faste partikler, bobler eller dråper innenfor stillestående væsker. Differensielle balanselikninger ... -
Lagrangian modeling of mass transfer from a single bubble rising in stagnant liquid
(Journal article; Peer reviewed, 2018)A Lagrangian model has been derived that describes the size, species composition and velocity of an individual gas bubble as it ascends through a vertical column with stagnant liquid and exchanges mass with the other phase. ... -
Large Area Patterning of Highly Reproducible and Sensitive SERS Sensors Based on 10-nm Annular Gap Arrays
(Peer reviewed; Journal article, 2022)Applicable surface-enhanced Raman scattering (SERS) active substrates typically require low-cost patterning methodology, high reproducibility, and a high enhancement factor (EF) over a large area. However, the lack of ... -
Large Scale Production of Blue Hydrogen
(Master thesis, 2023)Den globale etterspørselen etter energi øker, med en forventet etterspørsel på 180 Mt hydrogen i 2030. Den nåværende hydrogenproduksjonsmetoden er hovedsakelig dampreformering av naturgass, som er ansvarlig for 900 Mt av ... -
Large-Scale Granulation of CaO-Based Pellets for High-Temperature Carbon Dioxide Capture
(Master thesis, 2018)Abstract Pelletized CaO-based sorbents are made for the use in Moving Bed Carbonate Looping (MBCL) technology capturing CO2 at a low partial pressure of CO2 and high temperature, producing approximately 100% pure CO2. ... -
Lessons learned from an experimental campaign on promoting energy content of renewable biogas by injecting H2 during anaerobic digestion
(Peer reviewed; Journal article, 2020)Direct injection of H2 to an anaerobic reactor enables biological fixation of CO2 into CH4 (biomethanation) and consequently boosts methane content in the produced biogas. However, there has been only a small amount of ... -
Li-metal-free prelithiation of Si-based negative electrodes for full Li-ion batteries
(Journal article; Peer reviewed, 2015)Most of the high‐capacity positive‐electrode materials [for example, S, O2 (air), and MOx (M: V, Mn, Fe, etc.)] are Li‐deficient and require the use of a Li‐metal electrode or prelithiation. Herein, we report a novel ... -

Lignosulfonate Salt Tolerance and the Effect on Emulsion Stability
(Peer reviewed; Journal article, 2020)In this article, we adapted and compared methods to assess lignosulfonates for technical applications. Salt-induced agglomeration and precipitation were studied via mechanical separation and subsequent UV spectrometry. The ... -
Lignosulfonates in Crude Oil Processing: Interactions with Asphaltenes at the Oil/Water Interface and Screening of Potential Applications
(Peer reviewed; Journal article, 2020)The goal of this article is to test the potential application of lignosulfonates (LSs) in crude oil production and processing. Three LS samples of varying hydrophobicity and average molecular weight were considered. First, ... -
Limiting current density as a selectivity factor in electrodialysis of multi-ionic mixtures
(Peer reviewed; Journal article, 2023)Electrodialysis is a promising technology to remove low concentrations of target ions from multi-ionic mixtures. While the synthesis of selective membranes is a prominent topic in research, few studies have been presented ... -
Linear Combination of Gradients as Optimal Controlled Variables
(Peer reviewed; Journal article, 2020)In this paper, we show that optimal economic operation can be achieved using feedback control, by controlling the right variables that translate economic objectives into control objectives. We formulate a generic framework ... -
Linear parameter-varying model for a refuellable zinc-air battery
(Peer reviewed; Journal article, 2020)Due to the increasing trend of using renewable energy, the development of an energy storage system (ESS) attracts great research interest. A zinc–air battery (ZAB) is a promising ESS due to its high capacity, low cost and ... -
