Investigating the Nature of Discontinuous Shear Thickening: Beyond a Mean-Field Description
Jetin E. Thomas, Abhay Goyal, Deshpreet Singh Bedi +3
Dense suspensions can undergo a dramatic increase in viscosity at a critical value of the shear stress. This phenomenon, termed discontinuous shear thickening (DST), has been attri…
Flow induced rigidity percolation in shear thickening suspensions
Abhay Goyal, Nicos S. Martys, Emanuela Del Gado
Discontinuous shear thickening (DST) is associated with a sharp rise of a suspension's viscosity with increasing applied shear rate. A key signature of DST, highlighted in recent s…
Ion specificity of confined ion-water structuring and nanoscale surface forces in clays
Francis Dragulet, Abhay Goyal, Katerina Ioannidou +2
Ion specificity and related Hofmeister effects, ubiquitous in aqueous systems, can have spectacular consequences in hydrated clays, where ion-specific nanoscale surface forces can…
Like-charge attraction at the nanoscale: ground-state correlations and water destructuring
Ivan Palaia, Abhay Goyal, Emanuela del Gado +2
Like-charge attraction, driven by ionic correlations, challenges our understanding of electrostatics both in soft and hard matter. For two charged planar surfaces confining counter…
Ordered domains in sheared dense suspensions: the link to viscosity and the disruptive effect of friction
Abhay Goyal, Emanuela Del Gado, Scott Z Jones +1
Monodisperse suspensions of Brownian colloidal spheres crystallize at high densities, and ordering under shear has been observed at densities below the crystallization threshold. W…
