    • Cellulose nanofibrils as rheology modifier in mayonnaise – A pilot scale demonstration 

      Heggset, Ellinor Bævre; Aaen, Ragnhild; Veslum, Trinelise; Henriksson, Marielle; Simon, Sebastien Charles; Syverud, Kristin (Peer reviewed; Journal article, 2020)
      The applicability of cellulose nanofibrils (CNFs) as viscosifying agent in a starch-reduced low-fat mayonnaise and in an oil-reduced full-fat mayonnaise has been considered. For low-fat mayonnaise a 50 wt% reduction in the ...

    • Coating 3D Printed Polycaprolactone Scaffolds with Nanocellulose Promotes Growth and Differentiation of Mesenchymal Stem Cells 

      Elsebahy, Ahmad Rashad Saad Mohamed; Mohamed-Ahmed, Samih; Ojansivu, Miina; Berstad, Kaia; Yassin, Mohammed Ahmed; Kivijärvi, Tove; Heggset, Ellinor Bævre; Syverud, Kristin; Mustafa, Kamal Babikeir Eln (Journal article; Peer reviewed, 2018)
      3D printed polycaprolactone (PCL) has potential as a scaffold for bone tissue engineering, but the hydrophobic surface may hinder optimal cell responses. The surface properties can be improved by coating the scaffold with ...

    • A core flood and microfluidics investigation of nanocellulose as a chemical additive to water flooding for EOR 

      Aadland, Reidun Cecilie Grønfur; Akarri, Salem Saeed Fadhl; Heggset, Ellinor Bævre; Syverud, Kristin; Torsæter, Ole (Peer reviewed; Journal article, 2020)
      Cellulose nanocrystals (CNCs) and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (T-CNFs) were tested as enhanced oil recovery (EOR) agents through core floods and microfluidic experiments. ...

    • High-Temperature Core Flood Investigation of Nanocellulose as a Green Additive for Enhanced Oil Recovery 

      Aadland, Reidun Cecilie Grønfur; Jakobsen, Trygve Dagsloth; Heggset, Ellinor Bævre; Long-Sanouiller, Haili; Simon, Sebastien Charles; Paso, Kristofer Gunnar; Syverud, Kristin; Torsæter, Ole (Journal article; Peer reviewed, 2019)
      Recent studies have discovered a substantial viscosity increase of aqueous cellulose nanocrystal (CNC) dispersions upon heat aging at temperatures above 90 °C. This distinct change in material properties at very low ...

    • Interactions between Surfactants and Cellulose Nanofibrils for Enhanced Oil Recovery 

      Jakobsen, Trygve Dagsloth; Simon, Sebastien Charles; Heggset, Ellinor Bævre; Syverud, Kristin; Paso, Kristofer Gunnar (Journal article; Peer reviewed, 2018)
      Chemical enhanced oil recovery (EOR) represents a series of potential solutions for extracting more oil from resources with already known locations and magnitudes. Unfortunately, many of the chemical additives in use today ...

    • Mechanical properties of composite hydrogels of alginate and cellulose nanofibrils 

      Aarstad, Olav Andreas; Heggset, Ellinor Bævre; Pedersen, Ina S.; Bjørnøy, Sindre Hove; Syverud, Kristin; Strand, Berit Løkensgard (Journal article; Peer reviewed, 2017)
      Alginate and cellulose nanofibrils (CNF) are attractive materials for tissue engineering and regenerative medicine. CNF gels are generally weaker and more brittle than alginate gels, while alginate gels are elastic and ...

    • Oil-in-Water Emulsions Stabilized by Cellulose Nanofibrils—The Effects of Ionic Strength and pH 

      Aaen, Ragnhild; Brodin, Fredrik Wernersson; Simon, Sebastien Charles; Heggset, Ellinor Bævre; Syverud, Kristin (Journal article; Peer reviewed, 2019)
      Pickering o/w emulsions prepared with 40 wt % rapeseed oil were stabilized with the use of low charged enzymatically treated cellulose nanofibrils (CNFs) and highly charged 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized ...

    • Polymeric 3D scaffolds for tissue regeneration: Evaluation of biopolymer nanocomposite reinforced with cellulose nanofibrils
