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…
Disentangling the roles of roughness, friction and adhesion in discontinuous shear thickening by means of thermo-responsive particles
Chiao-Peng Hsu, Joydeb Mandal, Shivaprakash N. Ramakrishna +2
Dense suspensions of colloidal or granular particles can display pronounced non-Newtonian behaviour, such as discontinuous shear thickening (DST) and shear jamming (SJ). The essent…
Tuning Interparticle Hydrogen Bonding in Shear-Jamming Suspensions: Kinetic Effects and Consequences for Tribology and Rheology
Nicole M. James, Chiao-Peng Hsu, Nicholas D. Spencer +2
The shear-jamming of dense suspensions can be strongly affected by molecular-scale interactions between particles, e.g. by chemically controlling their propensity for hydrogen bond…
Roughness-dependent tribology effects on discontinuous shear thickening
Chiao-Peng Hsu, Shivaprakash N. Ramakrishna, Michele Zanini +2
Surface roughness affects many properties of colloids, from depletion [1] and capillary interactions [2], to their dispersibility [3] and use as emulsion stabilizers [4]. It also i…
