Size-dependent same-material tribocharging in insulating grains
Scott R. Waitukaitis, Victor Lee, James M. Pierson +2
Observations of flowing granular matter have suggested that same-material tribocharging de- pends on particle size, rendering large grains positive and small ones negative. Models…
Optimizing directed self-assembled morphology
Jian Qin, Gurdaman S. Khaira, Yongrui Su +4
Directed assembly of block polymers is rapidly becoming a viable strategy for lithographic patterning of nanoscopic features. One of the key attributes of directed assembly is that…
Particle Shape Effects on the Stress Response of Granular Packings
Athanasios G. Athanassiadis, Marc Z. Miskin, Paul Kaplan +7
We present measurements of the stress response of packings formed from a wide range of particle shapes. Besides spheres these include convex shapes such as the Platonic solids, tru…
Impact dynamics of granular jets with non-circular cross-sections
Xiang Cheng, Leonardo Gordillo, Wendy W. Zhang +2
Using high-speed photography, we investigate two distinct regimes of the impact dynamics of granular jets with non-circular cross-sections. In the steady-state regime, we observe t…
Shear thickening in concentrated suspensions: phenomenology, mechanisms, and relations to jamming
Eric Brown, Heinrich M. Jaeger
Shear thickening is a type of non-Newtonian behavior in which the stress required to shear a fluid increases faster than linearly with shear rate. Many concentrated suspensions of…
