Fabrication of ZnCoS nanomaterial for high energy flexible asymmetric supercapacitors

Yuan Zhang, Ning Cao, Sabine Szunerits, Ahmed Addad, Pascal Roussel, Rabah Boukherroub

Bimetal sulfides as anode electrode materials have attracted extensive attention owing to their superior electrochemical activity compared to their mono-metal sulfide counterparts. Herein, ZnCoS nanomaterial was synthesized by chemical precipitation and ion-exchange process. The obtained ZnCoS can...

Performance enhancement of 64 Gb/s OFDM system at 1550 nm over multimode fiber using Volterra equalization

Mahdi Kasmi, Hichem Mrabet, Sofien Mhatli, Faouzi Bahloul, Iyad Dayoub, Kyunghwan Oh

Based on a developed analytical model, we demonstrate the feasibility of intensity-modulation direct-detection (IM/DD) optical orthogonal frequency division multiplexing (OOFDM) system over 1 km of multimode fiber (MMF) at data rates up to 64 Gb/s, at 1550 nm. The effect of data rates, number of...

Non-reciprocal behavior of one-dimensional piezoelectric structures with space-time modulated electrical boundary conditions

Charles Croënne, Jerome O. Vasseur, Olivier Bou Matar, Anne-Christine Hladky, Bertrand Dubus

Propagation of longitudinal acoustic waves in a one-dimensional piezoelectric structure with space-time modulated electrical boundary conditions is investigated. An analytical model allowing the calculation of eigenmodes for spatially continuous shifts of electrical boundary conditions is compared...

Broadband terahertz heterodyne spectrometer exploiting synchrotron radiation at megahertz resolution

Jean-Francois Lampin, O. Pirali, Z. Buchanan, Sophie Eliet, M.-A. Martin-Drumel, J. Turut, Pascal Roy, Francis Hindle, Gaël Mouret

A new spectrometer allowing both high resolution and broadband coverage in the terahertz (THz) domain is proposed. This instrument exploits the heterodyne technique between broadband synchrotron radiation and a quantum cascade laser (QCL) based molecular THz laser that acts as the local oscillator...

Broadband dielectric characterization of flexible substrates using organic conductive polymer microstrip lines

Z. Hamouda, J. Wojkiewicz, A. Pud, S. Bergheul, T. Lasri

The interest from both consumers and industry toward flexible and organic electronics has grown enormously due to the unique properties of the materials used (flexible, stretchable, reconfigurable, and not easily breakable). In radio frequency and electronic organic systems fabrication, one...
