• Experimental study of volumetric sand production with gas flow 

  Varkas, Michail; Papamichos, Euripides; Berntsen, Andreas Nicolas (Journal article; Peer reviewed, 2024)

  The presence of sand in a production stream has been a common issue for wells drilled in high permeability sandstone formations. In the case of gas producing reservoirs, sand production can be particularly hazardous due ...

• In-process epimerisation of alginates from Saccharina latissima, Alaria esculenta and Laminaria hyperborea 

  Nøkling-Eide, Katharina; Aachmann, Finn Lillelund; Tøndervik, Anne; Arlov, Øystein; Sletta, Håvard (Journal article; Peer reviewed, 2024)

  Alginates are valued in many industries, due to their versatile properties. These polysaccharides originate from brown algae (Phaeophyceae) and some bacteria of the Azotobacter and Pseudomonas genera, consisting of 1 → 4 ...

• Film drainage and critical velocity of fluid particles in power-law fluids 

  Galantucci, Veronica; Ozan, Suat Canberk; Jakobsen, Hugo Atle (Journal article; Peer reviewed, 2024)

  This work studies the collision of fluid particles (bubbles or droplets) in non-Newtonian media whose viscosity obeys the power-law model, by analyzing the behavior of the drainage of the film between the particles. The ...

• Two decades of increasing functional and phylogenetic richness in a mountaintop flora in central Norway 

  Vanneste, Thomas; Graae, Bente Jessen; Kyrkjeeide, Magni Olsen; Lindmo, Sigrid; Michelsen, Ottar; Naranjo-Orrico, Domenica J.; Ray, Courtenay A.; Vandersteene, Matthias; Verheyen, Kris; De Frenne, Pieter (Journal article; Peer reviewed, 2024)

  Questions: Analysing how multiple facets of biodiversity vary across space and time can help to predict the vulnerability of mountaintop floras to future environmental changes. Here we addressed the following questions: ...

• Crystal-plasticity modelling of the yield surfaces and anelasticity in the elastoplastic transition of metals 

  Imani Aria, Arash; Holmedal, Bjørn; Manik, Tomas; Marthinsen, Knut (Journal article; Peer reviewed, 2024)

  The paper presents a full-field crystal-plasticity computational investigation of 10 με small-strain-offset yield surfaces with pointed vertexes that are seen in the elastoplastic transition of pre-strained polycrystal ...
