A cut-cell method for the numerical simulation of 3D multiphase flows with strong interfacial effects
Marco Picasso, Alexandre Caboussat, Alexandre Masserey, Julien Hess
We present a numerical model for the approximation of multiphase flows with free surfaces and strong interfacial effects. The model relies on the multiphase incompressible Navier-Stokes equations, and includes surface tension effects on the interfaces betw ...
Academic Press Inc Elsevier Science2024Measuring electro-adhesion pressure before and after contact
Herbert Shea, Sylvain Thomas Schaller
Electro-adhesion (EA) is a low-power, tunable, fast and reversible electrically-controlled adhesion method, effective on both conducting and insulating objects. Typically, only the electro-adhesive detachment force, i.e., the force required to separate an ...
NATURE PORTFOLIO2023The temporal dynamics of visual crowding and segmentation
Michael Herzog, Gregory Francis, Mauro Manassi
Perception of a target strongly deteriorates when flanking elements are presented (crowding). Classically, crowding is explained by pooling mechanisms where target and flanker features are combined, e.g., when neurons in higher visual areas with larger rec ...
2022KAT Ligation for Rapid and Facile Covalent Attachment of Biomolecules to Surfaces
Nako Nakatsuka, Nicholas Spencer
The efficient and bioorthogonal chemical ligation reaction between potassium acyltrifluoroborates (KATs) and hydroxylamines (HAs) was used for the surface functionalization of a self-assembled monolayer (SAM) with biomolecules. An alkane thioether molecule ...
2021Molecular simulations of interfacial systems: challenges, applications and future perspectives
Athanasios Nenes, Satoshi Takahama, Mária Lbadaoui-Darvas
We present a comprehensive review of methods and applications of molecular simulations of interfacial systems. We give a detailed overview of the main techniques and major challenges in the following aspects of solid and fluid surfaces: adsorption at solid ...
TAYLOR & FRANCIS LTD2021Studying the wettability of Si and eutectic Si-Zr alloy on carbon and silicon carbide by sessile drop experiments
Ludger Weber, Alberto Ortona, Manoj Kondibhau Naikade
The contact angles of two different systems, molten silicon and a eutectic Si-8 at. pct Zr alloy and their evolution over timeon vitreous carbon and polycrystalline silicon carbide (SiC) substrates were investigated at 1500 degrees C under vacuum, as well ...
ELSEVIER SCI LTD2019Theoretical framework to analyze the combined effect of surface tension and viscosity on the damping rate of sloshing waves
François Gallaire, Francesco Viola
Gravity force, surface tension, oscillating boundary layers, viscous dissipation, static meniscus, contact angle hysteresis, and moving contact lines are typical features of sloshing dynamics. All these ingredients influence capillary-gravity waves in a co ...
AMER PHYSICAL SOC2018Ultralow Interfacial Tension Measurement through Jetting/Dripping Transition
François Gallaire, Laura Augello
In this paper, we present a dynamic microfluidic tensiometer able to perform measurements over more than four decades and which is suitable for high throughput experimentations. This tensiometer is able to withstand hard conditions such as high pressure, h ...
American Chemical Society2017Study of synergetic effect, catalytic poisoning and regeneration using dielectric barrier discharge and photocatalysis in a continuous reactor: Abatement of pollutants in air mixture system
In the present work the abatement of butyraldehyde (BUTY), dimethyl disulfide (DMDS) and their mixtures in gas phase was studied in continuous reactor at three different configurations: photocatalysis (TiO2 + UV), dielectric barrier discharge (DBD) plasma ...
Elsevier Science Bv2017Grafted semiconductors on PE-films leading to bacterial inactivation: Synthesis, characterization and mechanism
César Pulgarin, Juan Kiwi, Sami Rtimi
This study reports the colloidal preparation FeOx, TiO2 and FeOx-TiO2 grafted on polyethylene (PE) films leading to bacterial inactivation. A fast bacterial inactivation was attained by the FeOx-TiO2 compared to the FeOx-PE film due to the interfacial char ...
