Modeling and Prediction of the Dynamic Viscosity of Nanofluids by a Homogenization Method

Ibrahim Zaaroura, Hilal Reda, Fabrice Lefebvre, Julien Carlier, Malika Toubal, Souad Harmand, Bertrand Nongaillard, Hassan Lakiss

Nanofluids are an innovative technology that can be used to improve the efficiency of heat transfer in systems such as coolers. Thermal system design requires access to all the physical properties of the nanofluids among which viscosity, thermal conductivity, and so on. Viscosity is an important...

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...

Numerical approach to quantify and characterize interface mechanical behavior between thin layer substrate and biological tissues

Marwa Sawan, Hilal Reda, Nadine Saad, Abbass Hamadeh, Sun Bin, Georges Nassar

In this paper, we investigate the behavior of biological tissues (skin) coupled to a substrate (sensor) based on a numerical model taking into account the relationship between strain/stress components at the interface. Based on this study, we understand and quantify the most appropriate...

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...

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...

[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...

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...

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...
