Enhanced electrocatalytic activity of PtRu/nitrogen and sulphur co-doped crumbled graphene in acid and alkaline media

Liuqing Pang, Yuanyuan Miao, Siddheshwar N Bhange, Alexandre Barras, Ahmed Addad, Pascal Roussel, Mohammed A Amin, Sreekumar Kurungot, Sabine Szunerits, Rabah Boukherroub

The low mass activity and high price of pure platinum (Pt)-based catalysts predominantly limit their large-scale utilization in electrocatalysis. Therefore, the reduction of Pt amount while preserving the electrocatalytic efficiency represents a viable alternative. In this work, we prepared new…

An experimental and systematic insight into the temperature sensitivity for a 0.15-µm gate-length HEMT based on the GaN technology

Mohammad Abdul Alim, Christophe Gaquière, Giovanni Crupi

Presently, growing attention is being given to the analysis of the impact of the ambient temperature on the GaN HEMT performance. The present article is aimed at investigating both DC and microwave characteristics of a GaN-based HEMT versus the ambient temperature using measured data, an equivalent…

Nanometer sized structures grown by pulsed laser deposition

Basma El Zein, Yao Yingbang, El Hadj Dogheche, Boulfrad Samir, Jabbour Ghassan

Nanometer sized materials can be produced by exposing a target to a laser source to remove material from the target and deposit the removed material onto a surface of a substrate to grow a thin film in a vacuum chamber

Towards III-V semiconductor-based artificial graphene

Nathali. A. Franchina Vergel, L. Christiaan Post, Davide Sciacca, Maxime Berthe, Francois Vaurette, Yannick Lambert, Dmitri Yarekha, David Troadec, Christophe Coinon, Guillaume Fleury, Abhishek Juyal, Julien Renard, Tao Xu, Ludovic Desplanque, Xavier Wallart, Daniel Vanmaekelbergh, Christophe Delerue, Bruno Grandidier

We present the fabrication and characterization of III-V semiconductor-based samples designed to mimic 2D material electronic properties thanks to a nanometer-scale honeycomb potential. STM/STS results demonstrate that a well reconstructed surface is recovered after processing and that the…

Temperature-sensitivity of two microwave HEMT devices: AlGaAs/GaAs vs. AlGaN/GaN heterostructures

Mohammad Abdul Alim, Abu Zahed Chowdhury, Shariful Islam, Christophe Gaquière, Giovanni Crupi

The goal of this paper is to provide a comparative analysis of the thermal impact on the microwave performance of high electron-mobility transistors (HEMTs) based on GaAs and GaN technologies. To accomplish this challenging goal, the relative sensitivity of the microwave performance to changes in…

Broadband sub-diffraction and ultra-high energy density focusing of elastic waves in planar gradient-index lenses

Jinfeng Zhao, Xiaodong Cui, Bernard Bonello, Bahram Djafari-Rouhani, Weitao Yuan, Yongdong P Pan, Jie Ren, Xiaoqing Zhang, Zheng Zhong

We demonstrate experimentally and theoretically the broadband sub-diffraction and ultra-high energy density focusing of elastic wave inside planar gradient-index (GRIN) plate lenses based on thickness variation. The full width at half maximum is ~0.40 times the minimum wavelength inside the lens λ0…

Concept of vertical liquid metal actuated cyclo‐olefin‐polymer based embedded 360° steerable Yagi‐Uda antenna

Denis Le Goff, Yves Quéré, Azar Maalouf, Eric Rius, Philippe Coquet, Edwin Hang Tong Teo

The concept of a reconfigurable 5GHz microfluidically actuated antenna with beam forming, steering and hoping in a 360° angular range, is presented in this paper. Its architecture is that of a Yagi-Uda array. Its actuation relies on the electrically controlled vertical displacement of liquid metal…

Facile synthesis of fluorine-free, hydrophobic, and highly transparent coatings for self-cleaning applications

Abderrahmane Hamdi, Julie Chalon, Pascal Laurent, Benoit Dodin, El Hadj Dogheche, Philippe Champagne

Non-fluorinated coatings have recently emerged as a new approach to avoid contamination on transparent surfaces. This research work concerns the synthesis of highly transparent, hydrophobic, durable, and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The…
