Global transmission and reflection coefficients of the ultrasonic component in porous media : a new approach

Georges Nassar, Amina Medjdoub, N. Saad

The purpose of this paper is to propose a new approach to determining the global ultrasonic transmission and reflection coefficients in a random porous medium. Boundary conditions at the interface of the medium were used to determine local transmission and reflection coefficients. A study of the…

Electron delay analysis and image charge effect in AlGaN/GaN HEMT on silicon substrate

Alain Agboton, N. Defrance, Philippe Altuntas, Vanessa Avramovic, Adrien Cutivet, Rezki Ouhachi, Jean-Claude de Jaeger, Samira Bouzid-Driad, Maher, Hassan, M. Renvoise, Peter Frijlink

A delay time analysis is carried out for SiN-passivated AlGaN/GaN High Electron Mobility Transistors (HEMTs) on silicon substrate featuring gate length of 90 nm. The influence of high parasitics in the access pads is considered using de-embedding procedure from the measured S parameters. From the…

The roles of biological interactions and pollutant contamination in shaping microbial benthic community structure

Haithem Louati, O. Ben Said, A. Soltani, P. Got, E. Mahmoudi, Cristiana Cravo-Laureau, Robert Duran, P. Aissa, O. Pringault

Biological interactions between metazoans and the microbial community play a major role in structuring food webs in aquatic sediments. Pollutants can also strongly affect the structure of meiofauna and microbial communities. This study aims investigating, in a non-contaminated sediment, the impact…

Improvement of the oxidation interface in an AlGaAs/AlxOy waveguide structure by using a GaAs/AlAs superlattice

J.Y. Song, S. Bouchoule, G. Patriarche, E. Galopin, A.M. Yacomotti, E. Cambril, Q.G. Kou, David Troadec, J.J. He, J.C. Harmand

The wet oxidation from the mesa sidewalls of AlGaAs/GaAs epitaxial structures is investigated in details. In addition to the intended lateral oxidation of the Al-rich buried layer, we observe a parasitic vertical oxidation of the adjacent layers of lower Al content. This vertical oxidation produces…

A crown-ether loop-derivatized oligothiophene doubly attached on gold surface as cation-binding switchable molecular junction

T.K. Tran, K. Smaali, M. Hardouin, Q. Bricaud, M. Oçafrain, P. Blanchard, S. Lenfant, S. Godey, J. Roncali, D. Vuillaume

A crown-ether dithiol quaterthiophene is synthesized and immobilized on gold surface by double covalent fixation. UV-vis spectroscopy and cyclic voltammetry show that the corresponding dithioester precursor can complex Pb2+ in solution and that this property is maintained for monolayers of the…
