Cyclones and attractive streaming generated by acoustical vortices

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Olivier Bou Matar

Acoustical and optical vortices have attracted great interest due to their ability to capture and manipulate particles with the use of radiation pressure. Here we show that acoustical vortices can also induce axial vortical flow reminiscent of cyclones, whose topology can be controlled by adjusting...

Insulin loaded iron magnetic nanoparticle–graphene oxide composites: synthesis, characterization and application for in vivo delivery of insulin

Kostiantyn Turcheniuk, Manakamana Khanal, Anastasiia Motorina, Palaniappan Subramanian, Alexandre Barras, Vladimir Zaitsev, Victor Kuncser, Aurel Leca, Alain Martoriati, Katia Cailliau-Maggio, Jean-Francois Bodart, Rabah Boukherroub, Sabine Szunerits

One of the focal subjects in insulin delivery is the development of insulin formulations that protect the native insulin from degradation under acidic pH in the stomach. In this work we show, for the first time, that a graphene oxide (GO) based matrix can ensure the stability of insulin at low pH....

Broadband attenuation of Lamb waves through a periodic array of thin rectangular junctions

Rayisa P. Moiseyenko, Yan Pennec, Rémi Marchal, Bernard Bonello, Bahram Djafari-Rouhani

We study theoretically subwavelength physical phenomena, such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. The resonances and antiresonances of periodically...

Evaluation de la peau du béton à l'aide de la technique des ondes ultrasonores de surface

Bogdan Piwakowski, Jean-Paul Balayssac, Géraldine Villain, Vincent Garnier, Mariusz Kaczmarek, Radoslaw Drelich

Concrete cover degradation is induced by aggressive agents in ambiance, chemicals, moisture, or temperature variations. Due to these degradations, a thin inhomogeneous surface layer usually appears. Its porosity and its elastic modulus are different from the properties of deeper sound concrete....

Narrow linewidth tunable terahertz radiation by photomixing without servo-locking

Antoine Rolland, Guillaume Ducournau, Gwennaël Danion, Goulc'Hen Loas, Marc Brunel, Alexandre Beck, Fabio Pavanello, Emilien Peytavit, Tashin Akalin, Mohammed Zaknoune, Jean-Francois Lampin, François Bondu, Marc Vallet, Pascal Szriftgiser, Denis Bacquet, Mehdi Alouini

A beatnote, tunable from dc to 1 THz, provided by a dual-frequency laser is used to feed an unitravelling carrier photodiode in order to produce a highly coherent THz signal radiated by a transverse-electromagnetic-horn antenna. The THz signal is detected and analyzed by a subharmonic mixer coupled...

Nonlinear measurement of non periodic pulse train with mixer based NVNA dedicated to radar power amplifier

Vincent Bridier, Damien Ducatteau, Maxime Olivier, Hans-Joachim Simon, François Graux, Philippe Eudeline, Gilles Dambrine

A measurement of time domain waveforms using a commercial two ports mixer based NVNA to measure a non periodic repetitive radar pulse train as a periodic one was performed. Then for the first time a 20GHz six port mixer based NVNA able to measure three different frequencies at the same time is...
