A hybrid Volume of Fluid Phase-Field method for Direct Numerical Simulations of soluble surfactant-laden interfacial flows

Ilies Haouche, Benjamin Reichert, Michael Baudoin, Palas Kumar Farsoiya

We present a hybrid Volume-of-Fluid (VoF) and Phase-Field method for general soluble surfactant-laden interfacial flows. The scheme retains the VoF method for interface tracking and momentum solution, while a diffused Phase-Field serves as a smooth carrier for surfactant transport enabling...

Review article: Tuning the gold electrode work function with thiol-based self-assembled monolayers

Khanh-Huyen Nguyen, Stéphane Lenfant

Abstract Self-assembled monolayers (SAMs) have emerged as a powerful strategy for interfacial engineering in organic and molecular electronics, enabling control of surface properties such as wettability, adhesion and electrode work function (WF). The WF is a key parameter for charge injection,...

Microfabricated vapor cells with tunable buffer gas mixtures using laser-actuated break-seal reservoirs

Clément Carlé, Gabriel Faure, Andrei Mursa, Shervin Keshavarzi, Quentin Tanguy, Emmanuel Klinger, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

Microfabricated cells are the core component of a wide variety of chip-scale atomic devices, such as clocks or magnetometers [1]. In those instruments, the cell is generally filled with a pressure of buffer gas. The presence of buffer gas reduces the atom-wall collision rate, enhances the atomic...

Lab-on-Chip Acoustic Detection Platform: Design, Fabrication and Performance Evaluation

Makrem Ben Abdelkader, Hatem Dahmani, Reda Aitayad, Samuel Dupont, Chérif Dridi, Julien Carlier

The growing demand for compact and high- sensitivity analytical platforms has accelerated the integration of micro-electro-mechanical systems (MEMS) with acoustic and microfluidic technologies. However, conventional sensors still face challenges in terms of miniaturization, fabrication cost, and...

Spatial Diversity and Multiplexing Modeling for Massive MIMO channels in Industrial Environments

Yunqi Feng, Pierre Laly, Eric P Simon, Valentin Picquet, Mamoun Guenach, Claude Desset, Nazar Muhammad Idrees, Wout Joseph, Emmeric Tanghe, Davy P Gaillot

<div><p>Spatial diversity gain and spatial multiplexing gain are two fundamental metrics to model the multiple-inputmultiple-output (MIMO) channel performance. To evaluate the benefit of deploying massive MIMO in industrial environments for smart factory applications, it is important to...
