Exceptional point enhances sensitivity of optomechanical mass sensors

P. Djorwe, Yan Pennec, Bahram Djafari-Rouhani

We propose an efficient optomechanical mass sensor operating at exceptional points (EPs), non-Hermitian degeneracies where eigenvalues of a system and their corresponding eigenvectors simultaneously coalesce. The benchmark system consists of two optomechanical cavities that are mechanically coupled...

T-ray modulation of light for future THz radios

Guillaume Ducournau

Modulation of light by external waves is an essential function in any photonics-based system. Using an integrated plasmonic approach, the speed of modulation of 1.55-μm waves has now been extended to the ‘low’ THz band.

Chitosan/hydroxyapatite modified carbon/carbon composites: synthesis, characterization and in vitro biocompatibility evaluation

Wenbo Wang, Ning Cao, Jianwen Dong, Rabah Boukherroub, Wei Liu, Yujie Li, Haibo Cong

Carbon/carbon composite (C/C), due to its bio-inert property, is prone to cause bone consolidation defects and bacterial infections in clinical applications. Therefore, there is a great demand in practical applications to prevent implant infections and enhance its bone consolidation capability. In...

Carbon-based quantum particles: an electroanalytical and biomedical perspective

Khadijeh Nekoueian, Mandana Amiri, Mika Sillanpää, Frank Marken, Rabah Boukherroub, Sabine Szunerits

Carbon-based quantum particles, especially spherical carbon quantum dots (CQDs) and nanosheets like graphene quantum dots (GQDs), are an emerging class of quantum dots with unique properties owing to their quantum confinement effect. Many reviews appeared recently in the literature highlightening...

High-order solution of nonlinear acoustic wave equation for isotropic solids using perturbation and finite difference methods

Wenhan Lyu, Xianmei Wu, Wei-Jiang Xu, Jiayi Chen

Nonlinear acoustic wave equation with Murnaghan parameters in isotropic solids is usually resolved by perturbation method [1-3]. High-order harmonics are obtained by expanding the equation in one linear and a series of nonlinear equations. It is found that errors in harmonics will be accumulated...

Contribution à l'étude de l'adhérence des structures du type couche sur substrat par modes de Rayleigh générés et détectés par sources laser, Contribution to the study of the adhesion of layer-on-substrate structures by Rayleigh modes generated and detected by laser sources

Martin Robin

La caractérisation non destructive de l’adhérence des structures du type couche sur substrat est un enjeu industriel et académique important. Ce type d’échantillon est en effet utilisé pour de nombreuses applications et sa durée de vie dépend en grande partie de la qualité d’adhérence des films au..., The non-destructive characterization of the adhesion of layer-on-substrate structures is an important issue in industrial and academic domains. This type of sample is indeed used for many applications and its lifetime depends mainly on the adhesion of the film to the substrate. This one changes...

Non destructive monitoring of mechanical stress in concrete for the survey of nuclear power plants

Jean François Chaix, Vincent Garnier, Rakotonarivo S., Bogdan Piwakowski, C. Ciccarone, Jean-Marie Henault, Odile Abraham, Géraldine Villain, Xavier Dérobert, G. Gugole, Olivier Durand, J.B. Legland, Jérôme Verdier, Hognon Sogbossi

To prevent consequences of damage in case of accident, some barriers of pre-stressed concrete are included in the nuclear power plant structures. Hence, to insure the nuclear security, it is important to control these structures. The nuclear accident induces pressure and temperature increases. This...

Passive guided wave tomography for pipes inspection

Tom Druet, Huu Tinh Hoang, Bastien Chapuis, Emmanuel Moulin

Structural Health Monitoring (SHM) consists in embedding sensors in a structure like aircraft fuselages, pipes or ship hulls in order to detect defects (for example cracks or corrosion in metallic materials or delamination in composite materials) before a serious damage occurs in the structure....

Synthesis of lead-free (Bi0,5Na0,5)TiO3 thin film by RF magnetron sputtering

Ahmad Hamieh, Freddy Ponchel, Denis Remiens, Sophie Barrau

This work concerns the growth of (Bi0,5Na0,5)TiO3 on Si/SiO2/LNO by RF magnetron sputtering. We observed, for the first time on BNT thin films, reactions that destroy the film. This behavior is associated to sodium or sodium oxide segregation. After an extensive description of the sodium impact...
