A micro-transducer matrix design for the detection of flexural guided waves

Hala El Rammouz, Farouk Benmeddour, Jamal Assaad, Emmanuel Moulin, Nikolay Smagin, Lucie Dupont, Lynda Chehami, Youssef Zaatar, Ziad Herro

In this paper, a new approach is proposed for the detection of ultrasonic guided waves using a LiNbO3 single crystal-based micro-transducer matrix. This matrix was designed, manufactured, and then used to detect Lamb and Pochhammer-Chree guided waves in plate- and cylinder-like structures. This…

[Invited] THz spintronic emitters with magnetoelectric control of the polarization and applications to polarimetry

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

We present a scheme to achieve coherent polarization rotation without multipolar or rotating external magnetic bias nor complex cascaded emitters, by exploiting artificially engineered strong uniaxial anisotropy in intermetallic heterostructures of rare-earth and transition metals. By replacing the…

Short term reliability and robustness of ultra-thin barrier, 110 nm-gate AlN/GaN HEMTs

Zhan Gao, Matteo Meneghini, Kathia Harrouche, Riad Kabouche, Francesca Chiocchetta, Etienne Okada, Fabiana Rampazzo, Carlo de Santi, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

Short-term reliability and robustness of 110 nm AlN/GaN HEMTs has been evaluated by means of off-state, semi-on state and on-state step stress tests on devices having different gate-drain distance, LGD. While breakdown voltages and critical voltages scale almost linearly with LGD, failure mode…

SDR Implementation of a Real-Time Testbed for Spectrum Sensing Under MIMO Time-Selective Channels for Cognitive Radio Applications

Hayfa Ben Thameur, Iyad Dayoub

Spectrum sensing (SS) is one of the major advanced features of the cognitive radio (CR) technology. Although multiple SS approaches have been introduced in the literature, the spectrum sensing is still a challenging operation from the practice perspective. Therefore, in this letter, we go one step…

Genipin-mediated immobilization of glucose oxidase enzyme on carbon felt for use as heterogeneous catalyst in sustainable wastewater treatment

May Kahoush, Nemeshwaree Behary, Jinping Guan, Aurélie Cayla, Brigitte Mutel, Vincent Nierstrasz

Enzyme immobilization is necessary process to improve the bioactivity and stability of the biocatalyst. In this study, glucose oxidase (GOx) enzyme was immobilized on plasma-treated fibrous carbon felt as a textile carrier to produce a heterogeneous catalyst. Genipin, as a naturally occurring…

Surface micromachining of chip-edge silicon microcantilevers using xenon difluoride etching of silicon-on-insulator

Thomas Lerond, Dmitri Yarekha, Vanessa Avramovic, Thierry Melin, S. Arscott

We demonstrate a straightforward surface micromachining process for the rapid prototyping of thin 'chip-edge' silicon microcantilevers protruding from the edge of a silicon-on-insulator chip. The process uses a single photolithographic mask-with xenon difluoride used to both pattern the…

Persistent microbial contamination of medical implant surfaces is becoming a serious threat to public health. This is principally due to antibiotic-resistant bacterial strains and the formation of bacterial biofilms. The development of novel antibacterial materials that will effectively fight both…

Thermal performance of self-rewetting gold nanofluids: application to two-phase heat transfer devices

Ibrahim Zaaroura, Souad Harmand, Julien Carlier, Malika Toubal, Aurélie Fasquelle, Bertrand Nongaillard

This paper presents an experimental analysis of the phenomenon of phase change inside a porous medium using different types of working fluids. It represents the impact of these fluids on improving the characteristics of heat and mass transfer in a Capillary Heat Pipe (CHP). In this study, gold…

Effect of Partial Ba Substitutions on the Crystallization of Sr2TiSi2O8 (STS) Glass–Ceramics and on the Generation of a SAW Signal at High Temperatures

Maurice Gonon, Florian Dupla, Hassan Alhousseini, Marc Duquennoy, Nikolay Smagin, Grégory Martic

Because of their characteristics, including a d33 of 10–15 pC/N and high stability up to temperatures over 1000 °C, polar glass–ceramics containing fresnoite crystals can be regarded as highly effective materials for applications requiring piezoelectricity at high temperatures. In the present paper…
