Subcellular imaging during single cell mechanical characterization

Deniz Pekin, Gregoire Perret, Quentin Rezard, Jean Claude Gerbedoen, Samuel Meignan, Dominique Collard, Chann Lagadec, Mehmet Tarhan

We report a method for combining confocal microscopy with single-cell mechanical characterization. This method allows investigating the effect of subcellular deformation (e.g. membranes, cytoplasm, cytoskeleton and organelles as endoplasmic reticulum, mitochondria, and nucleus) on cell mechanical…

Physicochemical characterizati on of the fuel by the ultrasound method

Said Soudani, Mohammed Mekkaoui, Georges Nassar, Ziane Derouiche

A physical medium, whatever its nature ,solid, liquid or gaseous is characterized by physicochemical parameter which are unique to it and which differentiate it from any other medium. But it can also be characterized and differentiated by its acoustic parameters: it’s like two sides of the same…

Hierarchical large-scale elastic metamaterials as an innovative passive isolation strategy for seismic wave mitigation

N. Kherraz, M. Miniaci, F. Bosia, A.S. S Gliozzi, M. Onorato, N.M. M Pugno

Large scale elastic metamaterials as an innovative passive isolation strategy for seismic waves has recently attracted increasing interest in the scientific community. In this work, we investigate the feasibility of an innovative design based on hierarchical organization of the unit cell, i.e. a…

Inducing dispersion curves with negative group velocity in inertially amplified phononic crystals through the application of an external state of prestress

M. Miniaci, M. Mazzotti, A. Amendola, F. Fraternali

In this paper, we report about the effect of the application of a state of prestress on the band structure of a periodic phononic crystal characterized by an inertial amplification mechanism. Through a numerical example, we show the possibility of inducing negative group velocity in an isolated…

Surface Functionalization with Polyethylene Glycol and Polyethyleneimine Improves the Performance of Graphene-Based Materials for Safe and Efficient Intracellular Delivery by Laser-Induced Photoporation

Jing Liu, Chengnan Li, Toon Brans, Aranit Harizaj, Shana van de Steene, Thomas de Beer, Stefaan de Smedt, Sabine Szunerits, Rabah Boukherroub, Ranhua Xiong, Kevin Braeckmans

Nanoparticle mediated laser-induced photoporation is a physical cell membrane disruption approach to directly deliver extrinsic molecules into living cells, which is particularly promising in applications for both adherent and suspension cells. In this work, we explored surface modifications of…

Channel Estimation Techniques for Millimeter-Wave Communication Systems: Achievements and Challenges

Kais Hassan, Mohammad Masarra, Marie Zwingelstein, Iyad Dayoub

The fifth-generation (5G) of cellular networks and beyond requires massive connectivity, high data rates, and low latency. Millimeter-wave (mmWave) communications is a key 5G enabling technology to meet these requirements thanks to its technical potentials that can be integrated with other 5G…

Nanomechanical modulation cavities of localized surface plasmon resonance with elastic whispering-gallery modes

Z. Oumekloul, M. Moutaouekkil, Gaëtan Lévêque, Abdelkrim Talbi, A. Mir, Abdellatif Akjouj

he dispersion of mechanical vibration limits nano-optomechanical modulation. In this work, we propose an optomechanical modulation exploiting elastic local resonances, also called whispering-gallery modes (WGMs). We find that our structure supports two quadripolar and two hexapolar elastic WGMs,…

Proposal for an integrated silicon-photonics terahertz gas detector using photoacoustics

Mattias Verstuyft, Elias Akiki, Benjamin Walter, Marc Faucher, Jean-Francois Lampin, Mathias Vanwolleghem, Bart Kuyken

A design and multiphysical model is presented for an on-chip gas sensor that transduces terahertz gas absorption through sound generation into a mechanical motion that can be read out externally. The signal is triply enhanced by designing a structure that functions simultaneously as an optical, an…

Active control of the transmission of Lamb waves through an elastic metamaterial

W. Wang, B. Bonello, Bahram Djafari-Rouhani, X. Fang, Yan Pennec, J. Zhao, Y. Jin

We have numerically investigated the transmission of an antisymmetric Lamb wave through a line of silicon pillars erected onto a homogeneous silicon plate when the frequency is tuned to a resonant frequency of the pillars. For either a bending mode or a compressional mode, the resonators emit in…
