Sliding or Rolling? Characterizing single-particle contacts
Simon Scherrer, Shivaprakash N. Ramakrishna, Vincent Niggel +4
Contacts between particles in dense, sheared suspensions are believed to underpin much of their rheology. Roughness and adhesion are known to constrain the relative motion of parti…

Tuning the shear-thickening of suspensions through surface roughness and physico-chemical interactions
Philippe Bourrianne, Vincent Niggel, Gatien Polly +2
Shear thickening denotes the reversible increase in viscosity of a suspension of rigid particles under external shear. This ubiquitous phenomenon has been documented in a broad var…
