Hexamolybdenum Clusters Supported on Graphene Oxide: Visible-Light Induced Photocatalytic Reduction of Carbon Dioxide into Methanol

Pawan Kumar, Harshal P. Mungse, Stéphane Cordier, Rabah Boukherroub, Om P. Khatri, Suman L Jain

Hexamolybdenum (Mo6) cluster-based compounds namely Cs2Mo6Bri8Bra6 and (TBA)2Mo6Bri8Bra6 (TBA = tetrabutylammonium) were immobilized on graphene oxide (GO) nanosheets by taking advantage of the high lability of the apical bromide ions with oxygen-functionalities of GO nanosheets. The loading of Mo6...

Optically-pumped continuous-wave terahertz sources

Philipp Latzel, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Guillaume Ducournau, X. Wallart, Jean-Francois Lampin

Recently we have improved the efficiency and the output power of our optically pumped continuous-wave THz sources. These sources are based on the beating of two laser lines in a wide bandwidth photodetector. Its intrinsic nonlinear behaviour is used to produce a beatnote at the frequency difference...

A planar micro thermoelectric generator with high thermal resistance

Zheng Yuan, Katir Ziouche, Zahia Bougrioua, Pascale Lejeune, Tuami Lasri, Didier Leclercq

This paper presents the modelling, design, fabrication and characterization of a planar micro thermoelectric generator (μTEG) which is able to convert waste heat into a few microwatts of electrical power. In order to get a better performance under a large variety of heat sources even if their...

Multiport Reflectometer Based on Subtractive Mixing

Abdelhatif El Fellahi, Kamel Haddadi, David Glay, Tuami Lasri

A compact multiport reflectometer using a new subtractive mixing scheme for the determination of reflection coefficients in the frequency range of 1-10 GHz is proposed. Compared with classical multiport reflectometers, the architecture proposed reduces the design complexity. Comparison between...

Measurement Accuracy and Repeatability in Near-Field Scanning Microwave Microscopy

S. Gu, Kamel Haddadi, A. El Fellahi, Gilles Dambrine, T. Lasri

We report on the accuracy and repeatability tests for near-field scanning microwave microscopy applications by associating a network analyzer and an evanescent microwave probe (EMP). A broadband matching network based on an interferometric technique is used to achieve a strong electromagnetic...

Tunability of Bragg band gaps in one-dimensional piezoelectric phononic crystals using external capacitances

Sebastien Degraeve, Christian Granger, Bertrand Dubus, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

A one-dimensional stack of identical piezoelectric rods is investigated. The device exhibits a band gap related to electrical boundary condition. A separate control of the central frequency and of the width of the band gap is performed by an electrical boundary condition involving two different...

Spectrum sensing applied to IR-UWB system based on M-OAM

Lamyae Maatougui, H. Ouahmane, A. Hajjaji, Khadija Hamidoun, Atika Rivenq, Yassin El Hillali

Intelligent transport system (ITS) exploits new communication and information technologies to make existing infrastructures more effective and more reliable, it resets on functions associated with the intelligence. The use of the ultra-wideband (UWB) appears as a very suitable technology for this...

Optimal Computation of Guided Wave Propagation and Scattering in Pipeworks Comprising Elbows: Numerical and Experimental Validations and Parametric Studies

M. El Bakkali, A. Lhemery, B. Chapuis, F. Berthelot, Sébastien Grondel

Simulation tools of guided wave (GW) examination are developed at CEA to help inspection design and results interpretation. In a previous paper [M. El Bakkali, A. Lhemery, V. Baronian and F. Berthelot, (AIP Conf. Proc. 1581), pp. 332-9 (2014)], a model was developed to deal with GW propagation in...
