Aging in humid granular media.

Physical review. E, Statistical, nonlinear, and soft matter physics

Restagno F, Ursini C, Gayvallet H, Charlaix E.
PMID: 12241167
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Aug;66(2):021304. doi: 10.1103/PhysRevE.66.021304. Epub 2002 Aug 23.

Aging behavior is an important effect in the friction properties of solid surfaces. In this paper we investigate the temporal evolution of the static properties of a granular medium by studying the aging over time of the maximum stability...

Fine calibration of the residual dissipation in a surface forces apparatus using a capacitive sensor.

The Review of scientific instruments

Leroy S, Restagno F, Charlaix E.
PMID: 19725677
Rev Sci Instrum. 2009 Aug;80(8):085103. doi: 10.1063/1.3187223.

The design of a dynamic surface force apparatus using a capacitive sensor has been useful in the past to study the nanorheological behavior of thin liquid films confined between a sphere and a plane. This allows a precise measurement...

Capillary bridge formation and breakage: a test to characterize antiadhesive surfaces.

The journal of physical chemistry. B

Vagharchakian L, Restagno F, Léger L.
PMID: 19673068
J Phys Chem B. 2009 Mar 26;113(12):3769-75. doi: 10.1021/jp807698s.

In order to characterize very weak adhesive surfaces, we have developed a quantitative test inspired by the Johnson, Kendall, and Roberts adhesion test for soft adhesives, which relies on the formation and then the rupture of a capillary bridge...

What is the mechanism of soap film entrainment?.

Langmuir : the ACS journal of surfaces and colloids

Saulnier L, Restagno F, Delacotte J, Langevin D, Rio E.
PMID: 22004182
Langmuir. 2011 Nov 15;27(22):13406-9. doi: 10.1021/la202233f. Epub 2011 Oct 24.

Classical Frankel's law describes the formation of soap films and their evolution upon pulling, a model situation of film dynamics in foams (formation, rheology, and destabilization). With the purpose of relating film pulling to foam dynamics, we have built...

Influence of Evaporation on Soap Film Rupture.

Langmuir : the ACS journal of surfaces and colloids

Champougny L, Miguet J, Henaff R, Restagno F, Boulogne F, Rio E.
PMID: 29498527
Langmuir. 2018 Mar 13;34(10):3221-3227. doi: 10.1021/acs.langmuir.7b04235. Epub 2018 Mar 02.

Although soap films are prone to evaporate due to their large surface to volume ratio, the effect of evaporation on macroscopic film features has often been disregarded in the literature. In this work, we experimentally investigate the influence of...

Temperature-Controlled Slip of Polymer Melts on Ideal Substrates.

Physical review letters

Hénot M, Grzelka M, Zhang J, Mariot S, Antoniuk I, Drockenmuller E, Léger L, Restagno F.
PMID: 30411954
Phys Rev Lett. 2018 Oct 26;121(17):177802. doi: 10.1103/PhysRevLett.121.177802.

The temperature dependence of the hydrodynamic boundary condition between a polydimethylsiloxane melt and two different nonattractive surfaces made of either an octadecyltrichlorosilane self-assembled monolayer or a grafted layer of short polydimethylsiloxane chains has been characterized. We observe a slip...

Patient-specific Alzheimer-like pathology in trisomy 21 cerebral organoids reveals BACE2 as a gene dose-sensitive AD suppressor in human brain.

Molecular psychiatry

Alić I, Goh PA, Murray A, Portelius E, Gkanatsiou E, Gough G, Mok KY, Koschut D, Brunmeir R, Yeap YJ, O'Brien NL, Groet J, Shao X, Havlicek S, Dunn NR, Kvartsberg H, Brinkmalm G, Hithersay R, Startin C, Hamburg S, Phillips M, Pervushin K, Turmaine M, Wallon D, Rovelet-Lecrux A, Soininen H, Volpi E, Martin JE, Foo JN, Becker DL, Rostagno A, Ghiso J, Krsnik Ž, Šimić G, Kostović I, Mitrečić D, Francis PT, Blennow K, Strydom A, Hardy J, Zetterberg H, Nižetić D.

Mol Psychiatry. 2020 Jul 10; doi: 10.1038/s41380-020-0806-5. Epub 2020 Jul 10.

A population of more than six million people worldwide at high risk of Alzheimer's disease (AD) are those with Down Syndrome (DS, caused by trisomy 21 (T21)), 70% of whom develop dementia during lifetime, caused by an extra copy...

Identifying the optimum chest compression point during cardiopulmonary resuscitation.

Sensing adsorption kinetics through slip velocity measurements of polymer melts.

The European physical journal. E, Soft matter

PMID: 29974276
Eur Phys J E Soft Matter. 2018 Jul 09;41(7):83. doi: 10.1140/epje/i2018-11697-4.

The evolution over time of the nonlinear slip behavior of a polydimethylsiloxane (PDMS) polymer melt on a weakly adsorbing surface made of short non-entangled PDMS chains densely end-grafted to the surface of a fused silica prism has been measured....

Roughness-Induced Friction on Liquid Foams.

Physical review letters

Marchand M, Restagno F, Rio E, Boulogne F.
PMID: 32242690
Phys Rev Lett. 2020 Mar 20;124(11):118003. doi: 10.1103/PhysRevLett.124.118003.

Complex liquids flow is known to be drastically affected by the roughness condition at the interfaces. We combined stresses measurements and observations of the flow during the motion of different rough surfaces in dry liquid foams. We visually show...

Near-surface rheology and hydrodynamic boundary condition of semi-dilute polymer solutions.

Soft matter

Guyard G, Vilquin A, Sanson N, Jouenne S, Restagno F, McGraw JD.

Understanding confined flows of complex fluids requires simultaneous access to the mechanical behaviour of the liquid and the boundary condition at the interfaces. Here, we use evanescent wave microscopy to investigate near-surface flows of semi-dilute, unentangled polyacrylamide solutions. By...
