Current trends in the physics of nanoscale friction
N. Manini, G. Mistura, G. Paolicelli +2
Tribology, which studies surfaces in contact and relative motion, includes friction, wear, and lubrication, straddling across different fields: mechanical engineering, materials sc…
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…
Size-dependent commensurability and its possible role in determining the frictional behavior of adsorbed systems
Paolo Restuccia, Mauro Ferrario, Pier Luigi Sivestrelli +2
Recent nanofriction experiments of xenon on graphene revealed that the slip onset can be induced by increasing the adsorbate coverage above a critical value, which depends on tempe…
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…
Deviation of viscous drops at chemical steps
Ciro Semprebon, Silvia Varagnolo, Daniele Filippi +4
We present systematic wetting experiments and numerical simulations of gravity driven liquid drops sliding on a plane substrate decorated with a linear chemical step. Surprisingly,…
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…
Frictional Transition from Superlubric Islands to Pinned Monolayers
Matteo Pierno, Lorenzo Bruschi, Giampaolo Mistura +6
The inertial sliding of physisorbed submonolayer islands on crystal surfaces contains unexpected information on the exceptionally incommensurate smooth sliding state associated wit…
Generation of water-in-oil and oil-in-water microdroplets in polyester-toner microfluidic devices
Evandro Piccin, Davide Ferraro, Paolo Sartori +3
This paper demonstrates that disposable polyester-toner microfluidic devices are suitable to produce either water-in-oil (W/O) or oil-in-water (O/W) droplets without using any surf…
Observation of the Imbert-Fedorov effect via weak value amplification
G. Jayaswal, G. Mistura, M. Merano
Weak measurements have recently allowed for the observation of the spin-Hall effect of light in reflection or transmission, which is a spin-dependent light beam shift orthogonal to…
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…
Thermolubricity of Xe monolayers on graphene
M. Pierno, L. Bignardi, M. C. Righi +6
The nanofriction of Xe monolayers deposited on graphene was explored with a quartz crystal microbalance (QCM) at temperatures between 25 and 50 K. Graphene was grown by chemical va…
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…
Weak measurement of the Goos-Hanchen shift
G. Jayaswal, G. Mistura, M. Merano
It is well known from quantum mechanics that weak measurements offer a means of amplifying and detecting very small phenomena. We present here the first experimental observation of…
Wetting of Argon on CO2
Giampaolo Mistura, Francesco Ancilotto, Lorenzo Bruschi +1
We have studied the wetting transition of Ar adsorbed on solid CO2 by means of high-precision adsorption isotherms measured with a quartz microbalance. We observe triple-point wett…
