Modification of MnFe2O4 surface by Mo (VI) pyridylimine complex as an efficient nanocatalyst for (ep)oxidation of alkenes and sulfides

N. Bouzari, A. Bezaatpour, B. Babaei, M. Amiri, Rabah Boukherroub, Sabine Szunerits

In this current paper, we report a new type of heterogeneous molybdenum (+6) complex, prepared by covalent grafting of cis-dioxo‑molybdenum (VI) pyridylimine complex on the surface of MnFe2O4 nanoparticles (NP) and characterized using various physicochemical techniques. The recyclable prepared…

Two-tone intermodulation performance of a 300GHz power amplifier MMIC

B. Schoch, A. Tessmann, A. Leuther, P. Szriftgiser, Guillaume Ducournau, I. Kallfass

Intermodulation effects play a decisive role in any system relying on the linear transmission of signals, such as highspeed wireless communication. For the first time, this paper presents measured third-order and fifth-order intermodulation performance of a 300GHz monolithic integrated circuit with…

Stability of the threshold voltage in fluorine-implanted normally-off AlN/GaN HEMTs co-integrated with commercial normally-on GaN HEMT technology

Florent Albany, François Lecourt, Ewa Walasiak, N. Defrance, Arnaud Curutchet, Hassan Maher, Yvon Cordier, Nathalie Labat, Nathalie Malbert

Fluorine ion migration in normally-off AlN/GaN HEMTs fabricated by fluorine ion plasma implantation technology is evidenced. Devices under test are co-integrated into the OMMIC commercial D006GH/D01GH MMIC process, providing fluorine-free normally-on HEMTs. Gate reverse bias step-stress experiment…

Diaryl Sulfide Derivatives as Potential Iron Corrosion Inhibitors: A Computational Study

Morad El-Hendawy, Asmaa Kamel, Mahmoud Mohamed, Rabah Boukherroub, Jacek Ryl, Mohammed Amin

The present work aimed to assess six diaryl sulfide derivatives as potential corrosion inhibitors. These derivatives were compared with dapsone (4,4′-diaminodiphenyl sulfone), a common leprosy antibiotic that has been shown to resist the corrosion of mild steel in acidic media with a corrosion…

Linear combining in dependent α-stable interference

Ce Zheng, Malcolm Egan, Laurent Clavier, Troels Pedersen, Jean-Marie Gorce

Recently, there has been a proliferation of wireless communication technologies in unlicensed bands for the Internet of Things. A key question is whether these networks can coexist given that they have different power levels, symbol periods, and access protocols. The main challenge is to…

Acoustic Tamm states in slender tubes

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Bahram Djafari-Rouhani

We present an analytical and numerical study of the possibility of existence of surface localized modes, the so-called Tamm states, in a one-dimensional (1D) comb-like phononic crystal (PnC). The structure is made out of periodic array of stubs of lengths d2grafted along a waveguide and separated…

UWB radar detection theory

Laila Sakkila, C. Tatkeu, Atika Rivenq, J. Zaidouni, Michael Bocquet

In this paper, a study of UWB receivers in terms of detection theory is presented. The UWB radar which is presented in many works previously [1]-[3] has many applications. For road UWB radar application, the receiver based on correlation is the optimum receiver [4]. In fact, it maximizes the…

Thermoacoustic wave generation in multilayered thermophones with cylindrical and spherical geometries

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat

A thermoacoustic sound generation model, based on the classical balance equations of the continuum mechanics, is here developed for the cylindrical and the spherical thermoacoustic wave generation. In both geometries, the model considers an arbitrary multilayered structure, where each layer can be…

Optomechanic Coupling in Ag Polymer Nanocomposite Films

Adnane Noual, Eunsoo Kang, Tanmoy Maji, Manos Gkikas, Bahram Djafari-Rouhani, George Fytas

Particle vibrational spectroscopy has emerged as a new tool for the measurement of elasticity, glass transition, and interactions at a nanoscale. For colloid-based materials, however, the weakly localized particle resonances in a fluid or solid medium renders their detection difficult. The strong…
