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…

Effect of particle stiffness and surface properties on the nonlinear viscoelasticity of dense microgel suspensions
Jacopo Vialetto, Shivaprakash N. Ramakrishna, Lucio Isa +1
Particle surface chemistry and internal softness are two fundamental parameters in governing the mechanical properties of dense colloidal suspensions, dictating structure and flow,…
