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...

Optimization of a tunable piezoelectric resonator using phononic crystals with periodic electrical boundary conditions

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Piezoelectric phononic crystals with periodic short-circuit conditions exhibit Bragg band gaps. They are used to design a Fabry-Perot cavity. The design of the device enables a modification of cavity length by a spatial shift of electrical boundary conditions. The resonator is thus tunable and a...

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...

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...

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...
