Probing technique for localized thermal conductivity measurement

K. Ziouche, Z. Bougrioua, P. Lejeune, T. Lasri, Didier Leclercq

A low-cost and non-destructive measurement technique based on the combination of a temperature sensor and a heater integrated in a very sharp tip is proposed for the determination of thermal conductivity of planar materials. The thermal sensor is fabricated by means of microtechnology technique.…

Multi-scale pore structure of COx claystone: Towards the prediction of fluid transport

Yang Song, Catherine A. Davy, David Troadec, Anne-Marie Blanchenet, Frédéric Skoczylas, Jean Talandier, Jean-Charles Robinet

We aim to relate the morphology of the pore network of finely porous claystones to their fluid transport properties. By using Focused Ion Beam in combination with Scanning Electron Microscopy (FIB/SEM), we image the pore network of COx claystone from 2D image stacks and as 3D reconstructed volumes…

Laser-ultrasound-based non-destructive testing

Frédéric Faëse, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy, Mohamed Ourak

Laser-ultrasound-based non-destructive testing (NDT) applications usually use circular or linear thermoelastic sources. This paper studies two more complex sources and presents their specific advantages. The first thermoelastic source is a regular line array, whereas the second one is a chirped…

Self-Equilibration of the Diameter of Ga-Catalyzed GaAs Nanowires

V. Dubrovskii, T. Xu, A. Díaz Álvarez, S.R. Plissard, P. Caroff, F. Glas, B. Grandidier

Designing strategies to reach monodispersity in fabrication of semiconductor nanowire ensembles is essential for numerous applications. When Ga-catalyzed GaAs nanowire arrays are grown by molecular beam epitaxy with help of droplet-engineering, we observe a significant narrowing of the diameter…

Towards high quality CVD graphene growth and transfer

G. Deokar, J. Avila, I. Razado-Colambo, Jean-Louis Codron, Christophe Boyaval, E. Galopin, M.-C. Asensio, D. Vignaud

Among the different graphene synthesis methods, chemical vapor deposition of graphene on low cost copper foil shows great promise for large scale applications. Here, we present growth experiments to obtain high quality graphene and its clean transfer onto any substrates. Bilayer-free monolayer…

Experimental study of passive defect localization in plates using ambient noise

Lynda Chehami, Julien de Rosny, Claire Prada, Emmanuel Moulin, Jamal Assaad

Passive listening methodology has been shown to be a practical and effective method for passive structural health monitoring. In this work, this approach is applied experimentally to monitor the occurrence of defects in thin aluminum plates. A correlation matrix is estimated from noise vibrations…

PFM Performances Analysis of PZT Piezoelectric Nano Cantilevers Fabricated on Si Wafer

Denis Remiens, Jean Costecalde, Denis Dezest, Fabrice Mathieu, Liviu Nicu

We present in this work and for the first time a high level of integration of piezoelectric nano-cantilevers on a silicon substrate (4 inches in diameter). We use lead titanate – zirconate material as piezoelectric material mainly because of its excellent piezoelectric activity at macro scale.…
