Active structuring of colloidal armour on liquid drops
Dommersnes, Paul; Rozynek, Zbigniew; Mikkelsen, Alexander; Castberg, Rene; Kjerstad, Knut; Hersvik, Kjetil; Fossum, Jon Otto (Journal article; Peer reviewed, 2013)Adsorption and assembly of colloidal particles at the surface of liquid droplets are at the base of particle-stabilized emulsions and templating. Here we report that electrohydrodynamic and electro-rheological effects ... -
Clay alignment in electric fields
Castberg, Rene; Rozynek, Zbigniew; Fossum, Jon Otto; Måløy, Knut Jørgen; Dommersnes, Paul; Flekkøy, Eirik Grude (Journal article; Peer reviewed, 2012)The response of rotational alignment of lithium fluorohectorite (Li-Fh) to an external electric field has been studied by employing image analysis. Large aggregates consisting of many single clay particles were prepared ... -
Dipolar ordering of clay particles in various carrier fluids
Rozynek, Zbigniew; Mauroy, Henrik; Castberg, Rene; Knudsen, Kenneth Dahl; Fossum, Jon Otto (Journal article; Peer reviewed, 2012)We investigate here examples of complexity in composite materials. The objective of the paper is to show that clay particles can be aligned in different hosting media, such as: silicone oil, paraffin-wax, polystyrene and ... -
Electric field nematic alignment of fluorohectorite clay particles in oligomeric matrices
Rozynek, Zbigniew; Castberg, Rene; Mikkelsen, Alexander; Fossum, Jon Otto (Journal article, 2013)We study the behavior of fluorohectorite synthetic clay particles dispersed in paraffin wax. We report wide-angle x-ray scattering related to electric-field-induced alignment of the embedded clay particles. The development ...
