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,...

An optical power divider based on mode coupling using GaN/Al2O3 for underwater communication

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, Tomy Abuzairi, El Hadj Dogheche

This paper details the design of a 1 \texttimes 8 optical power divider, using a gallium nitride (GaN) semiconductor on sapphire, which can be applied to underwater optical wireless communication. The design consists of nine parallel rectangular waveguides which are based on mode coupling phenomena...

Evaporation behavior of PEGylated graphene oxide nanofluid droplets on heated substrate

Pin Chen, Souad Harmand, Sabine Szunerits, Rabah Boukherroub

In this study, the evaporation behavior of graphene nanofluid droplets deposited on sapphire substrate was investigated in the temperature range from ambient to 106 °C. The evaporation process and the thermal mapping on the air/liquid interface of the droplets were recorded by side-view CCD camera...

22nm ultra-thin body and buried oxide FDSOI RF noise performance

Ousmane Kane, Luca Lucci, Pascal Scheiblin, Sylvie Lepilliet, Francois Danneville

The drastic downscaling of the transistor size along with advances in material sciences allowed the development of low power CMOS technologies with competitive RF figure of merits suitable for millimeter applications. In this context, this paper presents the RF and noise characterization (up to 110...

Multiple antenna receiver under impulsive SαS noise

Nicolas de Araujo Moreira, Laurent Clavier

In a usual MIMO framework when noise is assumed Gaussian, the channel matrix can be estimated with a Least Square approach. In addition, the Euclidean distance is optimal to detect the transmitted symbol. However, in dynamic interference, the Gaussian assumption is no longer valid. In this case,...

Synthesis of T-Nb2O5 thin-films deposited by atomic layer deposition for miniaturized electrochemical energy storage devices

Saliha Ouendi, Cassandra Arico, Florent Blanchard, Jean-Louis Codron, Xavier Wallart, Pierre-Louis Taberna, Pascal Roussel, Laurent Clavier, Patrice Simon, Christophe Lethien

Atomic Layer Deposition has been used to grow 30 to 90 nm-thick amorphous Nb2O5 films onto Pt current collectors deposited on Si wafer. While T-Nb2O5 polymorph is obtained by further annealing at 750 °C, the...

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...
