Ab initio Electronic Structure of Liquid Water

Alfredo Pasquarello, Wei Chen, Giacomo Francesco Leonardo Miceli, Francesco Ambrosio

Self-consistent GW calculations with efficient vertex corrections are employed to determine the electronic structure of liquid water. Nuclear quantum effects are taken into account through ab initio path-integral molecular dynamics simulations. We reveal a ...

2DVD Data Revisited: Multifractal Insights into Cuts of the Spatiotemporal Rainfall Process

Alexis Berne

Data collected during four heavy rainfall events that occurred in Ardeche (France) with the help of a 2D video disdrometer (2DVD) are used to investigate the structure of the raindrop distribution in both space and time. A first type of analysis is based o ...

Initiation of liquid-solid contact beneath an impacting drop

John Martin Kolinski

Before an impacting drop contacts the solid surface it must first drain the air beneath it. As a prelude to wetting, before any contact occurs, the impinging liquid confines the intervening air into a nanometers-thin film. Once liquid-solid contact initiat ...

Breaking Anchored Droplets in a Microfluidic Hele-Shaw Cell

François Gallaire, Pierre-Thomas Paul Brun

We study microfluidic self-digitization in Hele-Shaw cells using pancake droplets anchored to surface-tension traps. We show that above a critical flow rate, large anchored droplets break up to form two daughter droplets, one of which remains in the anchor ...

Isobaric first-principles molecular dynamics of liquid water with nonlocal van der Waals interactions

Alfredo Pasquarello, Giacomo Francesco Leonardo Miceli

We investigate the structural properties of liquid water at near ambient conditions using first-principles molecular dynamics simulations based on a semilocal density functional augmented with nonlocal van der Waals interactions. The adopted scheme offers ...

Validating formulas for the prediction of ascent speed and mass transfer coefficient for liquid oil droplets and gas bubbles under pressure

Jeremy Samuel Arey, Jonas Gros

Several different formulas exist to predict the ascent speed of gas bubbles and oil droplets released in deep waters. Similarly, different formulas are also available to predict the mass transfer coefficient of compounds dissolving into water during ascent ...

Cell Shape Dynamics Reveal Balance of Elasticity and Contractility in Peripheral Arcs

Jean-Jacques Meister, Chiara Gabella, Benoît Vianay, Céline Jeanne Labouesse

The mechanical interaction between adherent cells and their substrate relies on the formation of adhesion sites and on the stabilization of contractile acto-myosin bundles, or stress fibers. The shape of the cell and the orientation of these fibers can be ...

Solid on liquid deposition, a review of technological solutions

Roland Andreas Bitterli, Laure Jeandupeux

Solid-on-liquid deposition (SOLID) techniques are of great interest to the MEMS and NEMS (Micro- and Nano Electro Mechanical Systems) community because of potential applications in biomedical engineering, on-chip liquid trapping, tunable micro-lenses, and ...

Two-phase flow dynamics during boiling of R134a refrigerant in minichannels

This study is devoted to complex experimental investigation of two-phase flow boiling of R134a refrigerant in a minichannel having a hydraulic diameter of 540 μm at heat fluxes up to 70 kW/m2 and mass fluxes up to 700 kg/(m2 s). Flow regimes, pressure drop ...

Drops can bounce from perfectly hydrophilic surfaces

John Martin Kolinski

Drops are well known to rebound from superhydrophobic surfaces and from liquid surfaces. Here, we show that drops can also rebound from a superhydrophilic solid surface such as an atomically smooth mica sheet. However, the coefficient of restitution CR ass ...
