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…
Single-file escape of colloidal particles from microfluidic channels
Emanuele Locatelli, Matteo Pierno, Fulvio Baldovin +3
Single-file diffusion is a ubiquitous physical process exploited by living and synthetic systems to exchange molecules with their environment. It is paramount quantifying the escap…
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…
