Flower‐like nitrogen‐Co‐doped MoS2@rgo composites with excellent stability for supercapacitors

Min Li, Ahmed Addad, Yuan Zhang, Alexandre Barras, Pascal Roussel, Mohammed Amin, Sabine Szunerits, Rabah Boukherroub

Nitrogen-co-doped MoS2@rGO composites (named hereafter N-MoS2@N-RGO) are prepared by the hydrothermal method using dicyandiamide or hydrazine monohydrate as the nitrogen source. N-MoS2@rGO is obtained by the hydrothermal reaction...

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...

Enhanced visible light-triggered antibacterial activity of carbon quantum dots/polyurethane nanocomposites by gamma rays induced pre-treatment

Milica Budimir, Zoran Markovic, Jan Vajdak, Svetlana Jovanović, Pavel Kubát, Petr Humpoliček, Matej Mičušík, Martin Danko, Alexandre Barras, Dušan Milivojević, Zdenko Špitalský, Rabah Boukherroub, Biljana Todorović Marković

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...

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...

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...
