Conductance switching at the nanoscale of diarylethene derivative self-assembled monolayers on La_0.7Sr_0.3MnO₃

Louis Thomas, David Guérin, Benoît Quinard, Eric Jacquet, Richard Mattana, Pierre Seneor, Dominique Vuillaume, Thierry Melin, Stéphane Lenfant

We report on the phosphonic acid route for the grafting of functional molecules, optical switch (dithienylethene diphosphonic acid, DDA), on La_0.7Sr_0.3MnO₃ (LSMO). Compact self-assembled monolayers (SAMs) of DDA are formed on LSMO…

Pumping effect of heterogeneous meniscus formed around spherical particle

Hayate Nakamura, Tetsuya Ogawa, Motochika Inoue, Takuma Hori, Lizhong Mu, Harunori Yoshikawa, Farzam Zoueshtiagh, Georg Dietze, Takahiro Tsukahara, Ichiro Ueno

Hypothesis: A disturbance such as a microparticle on the pathway of a spreading droplet has shown the tremendous ability to accelerate locally the motion of the macroscopic contact line (Mu et al., J. Fluid Mech. 830, 2017) [1]. Although this ability has been linked to the particle-liquid…

The effect of thermal treatment on the neuronal cell biocompatibility of SU-8

Tiffany Baëtens, Severine Begard, Emiliano Pallecchi, S. Arscott, V. Thomy, Sophie S. Halliez

Future in vitro life science studies that require in situ functionalities—going beyond the common glass petri dish—can potentially be realized by using microsystems technologies to fabricate bio-microelectromechanical systems (BioMEMS) and laboratory-on-a-chip (LOC). One such material used to…

A theoretical insight into the use of anti-reflective coatings for the upliftment of sensitivity of surface plasmon resonance sensors

Chandreyee Manas Das, Qingling Ouyang, Xuan-Quyen Dinh, Philippe Coquet, Ken-Tye Yong

Surface Plasmon Resonance (SPR) based biosensors have been around in the scientific community for more than two decades and these have facilitated enormous improvement in the detection of complex biomolecules. Since, sensitivity of these sensors directly affects the ease of detection, our work here…

A broadband active microwave monolithically integrated circuit balun in graphene technology

Dalal Fadil, Vikram Passi, Wei Wei, Soukaina Ben Salk, Di Zhou, Wlodek Strupinski, Max C Lemme, Thomas Zimmer, Emiliano Pallecchi, Henri Happy, Sebastien Fregonese

This paper presents the first graphene radiofrequency (RF) monolithic integrated balun circuit. It is composed of four integrated graphene field effect transistors (GFETs). This innovative active balun concept takes advantage of the GFET ambipolar behavior. It is realized using an advanced silicon…

THz spectroscopy for fundamental science and applications

Jean-Francois Lampin, Gaël Mouret, Sukhdeep Dhillon, Juliette Mangeney

Many elementary process in matter, such as the interaction of electrons, spins and phonons as well as rotational modes of molecules possess resonances frequencies in the THz spectral range (1 THz = 1012 Hz) and dynamics on (sub)-picosecond time scales. Therefore, THz spectroscopy has become an…

Vision-based human action recognition: an overview and real world challenges

Imen Jegham, Anouar Ben Khalifa, Ihsen Alouani, Mohamed Ali Mahjoub

Within a large range of applications in computer vision, Human Action Recognition has become one of the most attractive research fields. Ambiguities in recognizing actions does not only come from the difficulty to define the motion of body parts, but also from many other challenges related to real…

Influence of the laser source position on the generation of Rayleigh modes in a layer–substrate structure with varying degrees of adhesion

Martin Robin, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy

Non-Destructive Testing of adhesion using Surface Acoustic Waves (SAW) is an important issue in industrial and academic domains. Indeed, these waves are sensitive to the quality of adhesion at the interface between the substrate and the layer with a thickness comparable to the acoustic wavelength.…

Novel insights into the charge storage mechanism in pseudocapacitive vanadium nitride thick films for high-performance on-chip micro-supercapacitors

Kevin Robert, Didier Stiévenard, D. Deresmes, Camille Douard, Antonella Iadecola, David Troadec, Pardis Simon, Nicolas Nuns, Maya Marinova, Marielle Huvé, Pascal Roussel, Thierry Brousse, Christophe Lethien

The Internet of Things, enabled by a worldwide network of interconnected sensors, is limited in its large-scale deployment of nomadic miniaturized devices due to the bounds of energy self-sufficiency. One possible solution, albeit challenging, is constructing on-chip pseudocapacitive micro-…

Temporal information based GoP adaptation for linear video delivery schemes

Anthony Trioux, François-Xavier Coudoux, Patrick Corlay, M Gharbi

An original wireless video transmission scheme called SoftCast has been recently proposed to deal with the issues encountered in conventional wireless video broadcasting systems (e.g. cliff effect). In this paper, we evaluate and optimize the performance of the SoftCast scheme according to the…
