Fluidization and wall slip of soft-glassy materials by controlled surface roughness
Ladislav Derzsi, Daniele Filippi, Giampaolo Mistura +5
The motion of soft-glassy materials (SGM) in a confined geometry is strongly impacted by surface roughness. However, the effect of the spatial distribution of the roughness remains…
Droplet breakup driven by shear thinning solutions in a microfluidic T-Junction
Enrico Chiarello, Anupam Gupta, Giampaolo Mistura +2
Droplet-based microfluidics turned out to be an efficient and adjustable platform for digital analysis, encapsulation of cells, drug formulation, and polymerase chain reaction. Typ…
Stretching of viscoelastic drops by steady sliding
Silvia Varagnolo, Daniele Filippi, Giampaolo Mistura +2
The sliding of non-Newtonian drops down planar surfaces results in a complex, entangled balance between interfacial forces and non linear viscous dissipation, which has been scarce…
Sliding droplets of Xanthan solutions: a joint experimental and numerical study
Silvia Varagnolo, Giampaolo Mistura, Matteo Pierno +1
We have investigated the sliding of droplets made of solutions of Xanthan, a stiff rodlike polysaccharide exhibiting a non-newtonian behavior, notably characterized by a shear-rate…
Sliding drops across alternating hydrophobic and hydrophilic stripes
M. Sbragaglia, L. Biferale, G. Amati +4
We perform a joint numerical and experimental study to sistematically characterize the motion of drops sliding over a periodic array of alternating hydrophobic and hydrophilic stri…
Stick-Slip Sliding of Water Drops on Chemically Heterogeneous Surfaces
Silvia Varagnolo, Davide Ferraro, Paolo Fantinel +5
We present a comprehensive study of water drops sliding down chemically heterogeneous surfaces formed by a periodic pattern of alternating hydrophobic and hydrophilic stripes. Drop…
