Response Surface Methodology for Understanding Glucose and Xylose Utilization by Clostridium beijerinckii NCIMB 8052
(Peer reviewed; Journal article, 2018)We applied response surface methodology to understand the effect and extend of carbon catabolite repression (CCR) on growth of Clostridium beijerinckii NCIMB 8052 using xylose and glucose as representative lignocellulosic ... -
Responses of Rat Mesenchymal Stromal Cells to Nanocellulose with Different Functional Groups
(Peer reviewed; Journal article, 2023)Cellulose nanofibrils (CNFs) are multiscale hydrophilic biocompatible polysaccharide materials derived from wood and plants. TEMPO-mediated oxidation of CNFs (TO-CNF) turns some of the primary hydroxyl groups to carboxylate ... -
Resynthesis of Cathode Active Material from Electric Vehicle Battery Waste and Metal Quantification along the Route
(Master thesis, 2021)In recent years, the amount of spent lithium-ion batteries (LIBs) from electric vehicles (EVs) has grown dramatically due to the increase of production of EVs as an alternative to the traditional internal combustion engine ... -
Reversed Hysteresis during CO Oxidation over Pd75Ag25(100)
(Journal article; Peer reviewed, 2016)CO oxidation over Pd(100) and Pd75Ag25(100) has been investigated by a combination of near-ambient-pressure X-ray photoelectron spectroscopy, quadrupole mass spectrometry, density functional theory calculations, and ... -
A review of degradation and emissions in post-combustion CO2 capture pilot plants
(Peer reviewed; Journal article, 2021)Pilot plant testing of amine solvents for post-combustion CO2 capture is an essential tool for fully understanding degradation behaviour and emission profiles under realistic process conditions. This review aims to summarise ... -
Rheological Properties of Gels Formed at the Oil−Water Interface by the Reaction between Tetrameric Acid and Calcium Ion under Flow Conditions and at the Batch Scale
(Journal article; Peer reviewed, 2019)The interfacial reaction between ARN tetrameric acid and Ca2+, which leads to the formation of calcium naphthenate deposits, was studied using a coaxial capillary device fitted to a profile analysis tensiometer. This device ... -
Rheological properties of highly concentrated dense packed layer emulsions (w/o) stabilized by asphaltene
(Journal article; Peer reviewed, 2015)Dense packed layers (DPLs) were sedimented and removed from various asphaltene stabilized w/o emulsion batches, and contained aqueous phase volume fractions (ϕ) between 0.701 and 0.808. These values are close to the ... -
Rheological Properties of Oil in Water Emulsions and Particulate Suspensions
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:176, Doctoral thesis, 2006)This thesis aims at a better understanding of the rheologicalproperties of the important colloids in oil industry, i.e. suspensions, emulsions and waxes. The rheology of suspension system is a complex field influenced by ... -
Rheology of silica-based dispersions and Cross-sectional modeling of settling slurries
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:170, Doctoral thesis, 2010)The stability and flow of suspensions (Rheology) is a complex field of investigation, but is of significant importance in many industrial processes in the oil industry. For colloidal particles, flow rheology becomes ... -
