Hydrothermal preparation of MoS₂/TiO₂/Si nanowires composite with enhanced photocatalytic performance under visible light

A. Hamdi, L. Boussekey, P. Roussel, A. Addad, H. Ezzaouia, Rabah Boukherroub, Yannick Coffinier

In this paper, we report on a simple, low cost and environmentally friendly method for the synthesis of 3D hierarchical molybdenum disulfide (MoS₂) nano-sheets on TiO₂ coated Si nanowires (SiNW). The synthetic method has several advantages such as low…

Porous Gold Films Fabricated by Wet-Chemistry Processes

Aymeric Pastre, Odile Cristini, Alexandre Boé, Katarzyna Raulin, Bertrand Grimbert, Fernand Chassagneux, Nathalie Rolland, Remy Bernard

Porous gold films presented in this paper are formed by combining gold electroless deposition and polystyrene beads templating methods. This original approach allows the formation of conductive films (2 × 106 (Ω·cm)−1) with tailored and interconnected porosity. The porous gold film was deposited up…

Delta-sigma based digital transmitters with low-complexity embedded-FIR digital to RF mixing

Razvan-Cristian Marin, Antoine Frappé, Andreas Kaiser

The focus of this contribution is to review delta-sigma based all-digital transmitters and to discuss issues related to large out-of-band quantization noise and possible coexistence problems. Low-complexity embedded-FIR filters are very interesting to relax the filtering constraints while keeping…

Investigation of the performance of HEMT based NO, NO2 and NH3 exhaust Gas Sensors for Automotive Antipollution Systems

Yacine Halfaya, Chris Bishop, Ali Soltani, Sundaram Suresh, Vincent Aubry, Paul L. Voss, Jean-Paul Salvestrini, Abdallah Ougazzaden

We report improved sensitivity to NO, NO2 and NH3 gas with specially-designed AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for operation in the harsh environment of diesel exhaust systems. The gate of the HEMT device is functionalized using a Pt catalyst for gas detection.…

LEAD-FREE BNT PIEZOELECTRIC THIN FILMS BY SOL-GEL METHOD

Sara Abou Dargham, Freddy Ponchel, M. Soueidan, Antonio Khoury, Jamal Assaad, Denis Remiens, Doumit Zaouk

The objective of this work is to synthesize lead-free piezoelectric thin films by the Sol-Gel method: bismuth sodium titanate (Bi0.5Na0.5TiO3 or BNT). BNT films were annealed with the rapid thermal process (RTP). The film treated at 700°C is dense and well crystallized in the perovskite phase. The…
