Kinetics-assisted discrimination of active sites in Ru catalyzed hydrolytic dehydrogenation of ammonia borane
(Journal article; Peer reviewed, 2019)Identifying the underlying nature of the structure sensitivity from the catalyst active site point of view in heterogeneous catalytic reactions is of prime scientific and industrial importance. In this work, the kinetics-assisted ... -
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 ... -

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
