Thermal characterization of GeSbTe alloys by Raman thermometry for Phase-Change Memories, Caractérisation thermique des alliages GeSbTe par thermométrie Raman pour les mémoires à changement de phase

Akash Patil

Phase change Materials have been the basis of memory storage beginning from its application for optical data storage in 1987. Fast forward to 2010s, phase change memories developed were 1000 times faster with greater endurance than NAND; and 10 times denser than DRAM. PMs based on chalcogenides…, Les matériaux à changement de phase sont à la base du stockage des mémoires depuis leur application au stockage optique des données en 1987. Dans les années 2010, les mémoires à changement de phase développées étaient 1000 fois plus rapides et plus endurantes que les mémoires NAND, et 10 fois plus…

Development of viscoelastic thin films to mitigate shock wave-induced laser damage in high power laser systems

Amira Guediche, Laurent Belliard, Bernard Perrin, Marc Duquennoy, Amandine Moiny, Mathieu Lafarie, Michel Boustié, Emilien Lescoute, Philippe Belleville, Hervé Piombini

Spallation effects caused by shock waves in optical components such as those used in the Laser MegaJoule facility during laser operation can lead to material fracture. One solution could be to use a viscoelastic thin film on these fused silica components to reduce the reflection of shock waves from…

Identification of <em>Cryptosporidium parvum</em> IIa and IId zoonotic subtype families and <em>Cryptosporidium bovis</em> from calves in Algeria

Lynda Sahraoui, Mohamed Mammeri, Myriam Thomas, Aurélie Chevillot, Bruno Polack, Isabelle Vallée, Jérôme Follet, Hacina Ain-Baaziz, Karim Tarik Adjou

Cryptosporidiosis is a significant disease in calves caused by the parasitic protist Cryptosporidium. The infection results in severe symptoms such as diarrhea, dehydration, delayed growth, and weight loss, often leading to mortality and economic losses. This study aimed to detect Cryptosporidium…

Acoustic noise levels and field distribution in 7 T MRI scanners

Louena Shtrepi, Vinicius Poggetto, Clement Durochat, Marc Dubois, David Bendahan, Fabio Nistri, Marco Miniaci, Nicola Maria Pugno, Federico Bosia

Acoustic noise production during Magnetic Resonance Imaging is an important source of patient discomfort and leads to verbal communication problems, difficulties in sedation, and hearing impairment. To address these issues, in this paper we present a systematic characterization of the acoustic…

Experimental evidence of nonreciprocal propagation in space-time modulated piezoelectric phononic crystals

S. Tessier Brothelande, C. Croënne, F. Allein, Jerome O. Vasseur, M. Amberg, Frédéric Giraud, Bertrand Dubus

A nonreciprocal system composed of a one-dimensional piezoelectric phononic crystal whose periodic electrical conditions are modulated in time is presented. One-way longitudinal wave propagation is studied experimentally and compared to finite element temporal simulations. The modulation is…
