The Optimum Dispersion of Carbon Nanotubes for Epoxy Nanocomposites: Evolution of the Particle Size Distribution by Ultrasonic Treatment

Frømyr, Tomas Roll; Hansen, Finn Knut; Olsen, Torbjørn (2012)

The ultrasonic dispersion of multiwalled carbon nanotube (MWCNT) suspensions was assessed by studying the differential sedimentation of the particles in an acid anhydride often employed as a curing agent for epoxy resins. ...
Preparation and characterisation of epoxy/alumina polymer nanocomposites

Johnsen, Bernt Brønmo; Frømyr, Tomas Roll; Thorvaldsen, Tom; Olsen, Torbjørn (2013)

The effect of adding nanosized alumina fillers of both fibre-like and spherical shapes to an epoxy polymer has been investigated. The alumina was dispersed in the epoxy hardener using two different sonication techniques. ...
Toxic effects of gunshot fumes from different ammunitions for small arms on lung cells exposed at the air liquid interface

Mariussen, Espen; Fjellbø, Lise Marie; Frømyr, Tomas Roll; Johnsen, Ida Vaa; Karsrud, Tove Engen; Voie, Øyvind Albert (2021-01-14)

Concerns have been raised as to whether gunshot fumes induce prolonged reduced lung capacity or even cancer due to inhalation. Gunshot fumes from three different types of ammunition calibre 5.56 mm × 45 NATO were investigated. ...
