Contactless Rheology of Soft Gels over a Broad Frequency Range

Zaicheng Zhang, Muhammad Arshad, Vincent Bertin, Samir Almohamad, Elie Raphaël, Thomas Salez, Abdelhamid Maali

We report contactless measurements of the viscoelastic rheological properties of soft gels. The experiments are performed using a colloidal-probe Atomic Force Microscope (AFM) in a liquid environment and in dynamic mode. The mechanical response is measured as a function of the liquid gap thickness…

Everlasting bubbles and liquid films resisting drainage, evaporation, and nuclei-induced bursting

Aymeric Roux, Alexis Duchesne, Michael Baudoin

Soap bubbles are by essence fragile and ephemeral. Depending on their composition and environment, bubble bursting can be triggered by gravity-induced drainage and/or the evaporation of the liquid and/or the presence of nuclei. They can also shrink due to the diffusion of the inner gas in the…

Ultrasonic investigation of the effect of compressive strains on 3D periodic bi-material structures

Lynda Chehami, Jingfei Liu, Pascal Pomarède, Paul Lohmuller, Boris Pittrowski, Fodil Meraghni, Nico Declercq

Due to the specific elastic properties such as high stiffness to mass ratio, regular microstructure materials are widely used in the industry. The need for nondestructive evaluation is ubiquitous to ensure material quality. As an effective nondestructive testing method, ultrasound has great…

Investigation of the Eigen Frequency of a Cantilever Microbeam Immersed in a Fluid Under the Piezoelectric Effect

Victory Elias, Flavie Braud, Philippe Champagne, Georges Nassar

In this paper, a new model of piezoelectric cantilever is developed, it can be heavily used in a micro electromechanical system (MEMS). This new prototype eliminates several risks caused by the previous means already used and increases the sensation in terms of rheology. Our approach is based on…

Dendritic Organic Electrochemical Transistors Grown by Electropolymerization for 3D Neuromorphic Engineering

K. Janzakova, M. Ghazal, A. Kumar, Yannick Coffinier, Sébastien Pecqueur, F. Alibart

One of the major limitations of standard top-down technologies used in today's neuromorphic engineering is their inability to map the 3D nature of biological brains. Here, it is shown how bipolar electropolymerization can be used to engineer 3D networks of PEDOT:PSS dendritic fibers. By…

Performance Projection of GaN HEMT: Bias and Temperature Dependent Study of 3 rd -Order Intermodulation Distortion

Mohammad Alim, I. Jahan, Mayahsa Ali, Christophe Gaquière

The third-order intermodulation distortion in AlGaN/GaN high electron mobility transistors fabricated on SiC substrate for power amplifier applications is reported in this study as a function of bias and temperature. The nonlinearity of active devices in terms of frequency and input power was…

Condensation and Growth of Amorphous Aluminosilicate Nanoparticles by Aggregation Process

Romain Dupuis, Seung Ho Hahn, Adri C. T. van Duin, Roland Pellenq, Arnaud Poulesquen

The precipitation of zeolite nanoparticles involves the initial formation of metastable precursors such as amorphous entities that crystalize through non-classical pathways. Here, using reactive force field based simulations, we reveal how aluminosilicate oligomers grow concomitantly to the…

Thèse

Functional metasurfaces controlled by Liquid crystals, Métasurfaces fonctionelles contrôlées par cristaux liquides

Racha Chamseddine

The main goal of this thesis was to dynamically control the reflectivity of a metasurface using LC technologies. The metasurfaces, tunable by voltage-controlled LC orientation, operate in a reflect-array mode and exhibit a high contrast ratio between quasi total absorption and low reflection,…, Le but principal de cette thèse a été de contrôler dynamiquement la réflectivité d’une métasurface par cristaux liquides. Les métasurfaces, dont les propriétés électromagnétiques sont contrôlées électriquement par l’orientation des molécules LC, fonctionnent en réflexion et présentent un très fort…
