Nano-particle mass sensing using phononic pillars

Bonhomme Jeremy, Oudich Mourad, Bahram Djafari-Rouhani, Sarry Frederic, Yan Pennec, Bonello Bernard, Beyssen Denis, Paul Charette

In this work, we investigate the sensitivity of a pillar based metasurface in order to understand the behavior of the system in real tests conditions where the mass perturbation will not be homogeneous on all the system. The structure we study is composed in stacking alternate layers of Silica and…

The electrostatically forced Faraday instability: theory and experiments

Kevin Ward, Satoshi Matsumoto, Ranga Narayanan

The onset of interfacial instability in two-fluid systems using a viscous, leaky dielectric model is studied. The instability arises as a result of resonance between the parametric frequency of an imposed electric field and the system's natural frequency. In addition to a rigorous model that…

Development of a Dual-band Printed Antenna Based on a Nanocomposite Material made of Polyaniline charged by Iron-Nickel Nanopowder

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, Lamine Kone, S. Bergheul, T. Lasri

One of the major challenges of printed electronics is to develop materials for flexible devices. Among these latter, antennas occupy a place of choice because of the new applications which are emerging. In this paper a flexible antenna based on a new nanocomposite, Polyaniline (PANI) charged by…

A Comparative Investigation of Plasmonic Properties between Tunable Nanoobjects and Metallized Nanoprobes for Optical Spectroscopy

Damien Eschimese, Patrick Hsia, Francois Vaurette, D. Deresmes, De Philippe Bettignies, Joachim Schreiber, Marc Chaigneau, S. Arscott, Gaëtan Lévêque, Thierry Melin

In order to evaluate the optical efficiency of tip-based probes for future tip-enhanced optical spectroscopy applications, we developed an experimental setup based on the coupling of an achromatic inverted microscope equipped with a total internal reflection objective and an atomic force microscopy…

FTIR and X-ray micro-tomography on Itokawa particles and carbonaceous chondrites

Rosario Brunetto, Zélia Dionnet, Alice Aléon-Toppani, Donia Baklouti, Ferenc Borondics, Zahia Djouadi, Andrew King, Tomoki Nakamura, Stefano Rubino, Christophe Sandt, David Troadec, Akira Tsuchiyama

We report a combined IR and X micro-tomography analysis of five particles from asteroid Itokawa and a few selected fragments of several carbonaceous chondrites. These techniques are an efficient first-step in a multi-technique analytical sequence to be applied on small Solar System bodies samples,…

Sensitivity to Dispersion Forces in First-Principles Modeling of Disordered Chalcogenides

Carlo Massobrio, Évelyne Martin, Ziyad Chaker, Mauro Boero, Assil Bouzid, Sébastien Le Roux, Guido Ori

The inclusion of dispersion (van der Waals, vdW) forces in first-principles modeling of disordered chalcogenides is analyzed and critically discussed in view of their impact on the atomic structure. To this purpose we considered the case of glassy GeTe4. We selected a vdW correction (termed vdWG…

Étude par microscopie à sonde locale des propriétés électriques de monocouches auto-assemblées de molécules photo-commutables sur substrats ferromagnétiques, C-AFM study of photoswitchable Self-Assembled Monolayers on ferromagnetic substrates

Louis Thomas

Ce manuscrit traite du transport à travers des monocouches auto-assemblées (self-assembled monolayers, SAMs) de molécules photoisomérisables greffées sur des matériaux ferromagnétiques (FMs) pour des applications à la frontière de l'électronique moléculaire et de la spintronique. Ces systèmes…, This thesis focuses on electrical transport through self-assembled monolayers (SAMs) of photoisomerisable compounds grafted on ferromagnetic materials (FMs) for applications at the frontier between molecular electronics and spintronics. These systems have been characterized by conductive atomic…
