High quality factor Hybrid SAW/BAW resonators

S. Barsoum, C. Hellion, E. Vermande, J.M. Quemper, M. Bousquet, A. Reinhardt, T. Laroche, S. Ballandras, Bertrand Dubus

We report hybrid SAW/BAW resonators based on arrays of AlN/Mo transducers located atop a silicon substrate. Thanks to an optimized fabrication process, these devices exhibit quality factors up to 3,900 and 1,700 respectively for the pseudo-SAW and pseudo-BAW modes, at frequencies close to 600 MHz...

Cathodic Activation of Titania-Fly Ash Cenospheres for Efficient Electrochemical Hydrogen Production: A Proposed Solution to Treat Fly Ash Waste

Tariq Altalhi, Amine Mezni, Mohamed Ibrahim, Moamen Refat, Adil Gobouri, Ayham Safklou, Adel Mousli, Mohamed Attia, Purna Boruah, Manash Das, Jacek Ryl, Rabah Boukherroub, Mohammed Amin

Fly ash (FA) is a waste product generated in huge amounts by coal-fired electric and steam-generating plants. As a result, the use of FA alone or in conjunction with other materials is an intriguing study topic worth exploring. Herein, we used FA waste in conjunction with titanium oxide (TiO2) to...

Three port photonic and plasmonic demultiplexers based on Cross and U-shaped stub structures: Application for filtering and sensing

S. Khattou, M. Amrani, A. Mouadili, E. El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We propose the design of three port photonic and plasmonic demultiplexers where filtering toward the two outputs is based on the phenomena of Fano resonances and electromagnetically induced transparency (EIT). We use a Cross-shape resonator in one output and a U-shape resonator composed of two...

Fully reversible magnetoelectric voltage controlled THz polarization rotation in magnetostrictive spintronic emitters on PMN-PT

Geoffrey Lezier, Pierre Koleják, Jean-Francois Lampin, K Postava, Mathias Vanwolleghem, Nicolas Tiercelin

THz polarization control upon generation is a crucially missing functionality. THz spintronic emitters based on the inverse spin Hall effect (ISHE) allow for this by the strict implicit orthogonality between their magnetization state and the emitted polarization. This control was until now only...

Visualization and Comprehension of Electronic and Topographic Contrasts on Cooperatively Switched Diarylethene-Bridged Ditopic Ligand

Imen Hnid, Lihao Guan, Elarbi Chatir, Saioa Cobo, Frédéric Lafolet, François Maurel, Jean-Christophe Lacroix, Xiaonan Sun

Diarylethene is a prototypical molecular switch that can be reversibly photoisomerized between its open and closed forms. Ligands bpy-DAE-bpy, consisting of a phenyl-diarylethene-phenyl (DAE) central core and bipyridine (bpy) terminal substituents, are able to self-organize. They are investigated...

Du CND par ultrasons au SHM pour le contrôle de l’intégrité des bétons : bilan et perspectives

Jean-Francois Chaix, Vincent Garnier, Odile Abraham, Géraldine Villain, Bogdan Piwakowski

Le Contrôle Non Destructif de l’intégrité des bétons est un domaine d’intérêt pour le diagnostic des enceintes de confinement des centrales de production d’énergie. Parmi les différentes méthodes les techniques ultrasonores présentent un potentiel intéressant et sont sensibles à différentes...

Optimisation de dispositifs immergés munis de raidisseurs quasi-périodiques pour des fonctions de discrétion et de furtivité

Charles Croënne, Samuel Deleplanque, Bertrand Dubus, Anne-Christine Hladky-Hennion, Corentin Coguenanff, Raphaël Lardat

La discrétion et la furtivité des véhicules sous-marins est une problématique importante en acoustique sous-marine. Ces véhicules sont dotés d’une coque métallique périodiquement renforcée par des raidisseurs qui affectent fortement les champs rayonnés ou diffractés à travers des phénomènes tels...
