Congratulations to Camila, Christina & Jan on the publication in Nature Asia Materials: "Fractionation of cellulose nanocrystals: enhancing liquid crystal ordering without promoting gelation" !

In a successful collaboration with Prof. Roland Sanctuary's group here at the physics & materials science research unit, this latest research on CNCs (cellulose nano crystals) describes in detail how controlling the fractionation of CNCs according to length can help in preventing the onset of gelation in solutions. The experimental results are discussed against what is already known regarding the aggregation of colloids based on the presence of counterions, and what still needs to be established in the field.

According to the authors: "Our results shine new light on the competition between liquid crystal formation and gelation in nanoparticle suspensions and provide a path for enhanced control of CNC self-organization for applications in photonic crystal paper or advanced composites."
