Electrochemical impedance spectroscopy of an evolving conducting polymer dendrite in water

Antoine Baron, Sébastien Pecqueur

Deposition of PEDOT:PSS is triggered alternatively on two gold wires distant of 240 µm from each other. The gold wires are immersed in a drop of water containing 10 mM of EDOT, 1 mM of sodium polystyrene sulfonate (NaPSS) and 10 mM of benzoquinone (BQ). The growth is captured with a camera and the...

Ab Initio Study of the Crystalline Structure of HgS under Low and High Pressure

Ahmed Amine Aidouni, Abdelkader Aissat, Mounir Ould-Mohamed, Mohamed El Amine Benamar, Samuel Dupont, Jean Pierre Vilcot

This study analyzes the lattice dynamics of HgS under various pressures using ab initio self-consistent calculations based on the plane-wave method (PW) and generalized gradient approximation (GGA). The static study, performed by enthalpy calculations, predicts that the transition from the cinnabar...

Evaluation of the Impact of Infusion Set Design on the Particulate Load Induced by Vancomycin–Piperacillin/Tazobactam Incompatibility

Laura Négrier, Bertrand Décaudin, Anthony Treizebré, Marie Guilbert, Pascal Odou, Anthony Martin Mena

Introduction: Drug incompatibilities are among the most common medication errors in intensive care units. A precipitate can form and block the catheter or cause an adverse event in the patient. Intensive care units have implemented various strategies for limiting the occurrence of these...

Broadband high-contrast-grating-type waveplates for the terahertz range

Surya Revanth Ayyagari, Andreas K Klein, Simonas Indrišiūnas, Vytautas Janonis, Daniil Pashnev, Abdu Subahan Mohammed, Guillaume Ducournau, Andreas Stöhr, Irmantas Kašalynas

The high-contrast-grating waveplates utilizing high contrast between silicon and air refractive indexes were developed in order to perform as a quarter wave and a half wave plate in the selected THz frequency range. The waveplates possessed anti-reflective properties due to the specific inclination...

TileChain: A Blockchain-Based Framework for Security Service Management For Vehicular Communications

Ahmed Didouh, Anthony Bahadir Lopez, Houda Labiod, Yassin El Hillali, Atika Rivenq, Mohammad Abdullah Al Faruque

Vehicular communications have become essential for functional and road safety purposes due to the development of vehicle fleets. However, these communications have made vehicles more vulnerable to cyber-attacks. The security of data exchanges in vehicular networks currently relies on a centralized...

Simulation and optimization of GaAs1-xPx/Si1-yGey/Ge triple junction solar cells

A. Azzououm, A. Aissat, Jean-Pierre Vilcot

This paper focuses on studying and simulating a GaAs1-xPx/Si1-yGey/Ge triple-junction solar cell structure. First, the strain and the bandgap energy associated to the SiGe layer have been studied. The optimal germanium concentration is 0.88 with a strain around 0.45%. Then, the phosphor...

Combined Super-Resolution Fluorescence and Coaxial 3-D Scanning Microwave Microscopy: Proof-of-Concept In-Liquid Live-Cell Imaging: Toward a Biological Nano-Radar

Chia-Hung Lee, Kamel Haddadi, Peter Burke

We present a proof-of-concept 3-D scanning microwave microscope based on a miniaturized coaxial probe combined with high-resolution fluorescence microscopy for in-liquid operation and live-cell imaging. The system simulta- neously provides electric (GHz) and optical (super-resolution) imaging of...

Tilted columnar metal film as transducer of transverse coherent acoustic phonons in picosecond acoustics

A. Chargui, N. Martin, G. Ferro, Arnaud Devos

Picosecond acoustics has been widely used to study thin film elasticity, hypersound attenuation, and adhesion of thin films to substrates. A major limitation of the technique is its restriction to only longitudinal waves. Although work has been reported on the ultrafast generation and detection of...
