Single-Cell Electrochemical Aptasensor Array

Shuo Li, Yannick Coffinier, Chann Lagadec, Fabrizio Cleri, Katsuhiko Nishiguchi, Akira Fujiwara, Soo Hyeon Kim, Nicolas Clément

Despite several demonstrations of electrochemical devices with limits of detection (LOD) of 1 cell/mL, the implementation of single-cell bioelectrochemical sensor arrays has remained elusive due to the challenges of scaling up. In this study, we show that the recently introduced nanopillar array…

Porous silicon-nanowire-based electrode for the photoelectrocatalytic production of hydrogen

Jingxian Wang, Caroline Keller, Paul Olli, Pascal Gentile, Stéphanie Pouget, Hanako Okuno, Mohamed Boutghatin, Yan Pennec, Hannah Johnson, Valérie Reita, Adina Morozan, Pascale Chenevier, Duc Nguyen, Vincent Artero

Photoelectrochemical water splitting is a sustainable and environmentally friendly way to produce green hydrogen, for which the practical fabrication of low-cost photoelectrodes remains a challenge. Here we report a porous photocathode assembly based on silicon nanowires (SiNW) as a light absorber…

The Ground State of Epitaxial Germanene on Ag(111)

Kai Zhang, Marie-Christine Hanf, Romain Bernard, Yves Borensztein, Hervé Cruguel, Andrea Resta, Yves Garreau, Alina Vlad, Alessandro Coati, Davide Sciacca, Bruno Grandidier, Mickael Derivaz, Carmelo Pirri, Philippe Sonnet, Régis Stephan, Geoffroy Prévot

Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, appear very promising due to their outstanding electronic properties, such as the quantum spin Hall effects. While there have been many claims of germanene monolayers up to now, no experimental evidence of a honeycomb…

Boosting III-Nitride Solar Cell Efficiency Using a Semibulk Absorber and Piezo-Phototronic Effect

Rabeb Belghouthi, Sahar Ammar, Jean-Paul Salvestrini, Nejiba Aoun, Mounir Ben El Hadj Rhouma

In solar cell applications, III-nitrides have appeared as a suitable candidates principally due to their photovoltaic properties. Nevertheless, the performance of the fabricated devices did not fit the theoretical expectation. This is generally attributed to a poor crystalline quality of the InGaN…

A simulation tool to interpret error rates in LoRa systems under frequency-sweeping jamming

Artur de São José, Virginie Deniau, Alexandre Boé, Eric Pierre Simon

In a recent experimental study, we submitted a LoRa system to jamming attacks, consisting of frequency-sweeping intentional electromagnetic interference. In the present contribution, we reproduce this scenario in a computational environment aiming to explain the previously observed phenomena based…

Strong Acousto-Plasmonic Coupling in Film-Coupled Nanoparticles Mediated by Surface Acoustic Waves

Adnan Noual, Rock Akiki, Gaëtan Lévêque, Yan Pennec, Houssaine El Boudouti, Bahram Djafari-Rouhani

The interaction between phonons and localized plasmons in film-coupled nanoparticles designs can be exploited both for modulating the scattered electromagnetic field and the understanding of the mechanical vibrations at nanoscale. In this paper, we show by finite element numerical analysis an…

Automated and Robotic On-Wafer Probing Station

Cerine Mokhtari, Clément Lenoir, Mohamed Sebbache, Kamel Haddadi

Emergent microwave and millimetre-wave technologies call for new and more accurate characterization techniques. In particular, repeatability of on-wafer calibration and measurements methods must be addressed. In this work, we are presenting the hardware and software development of a new…

Petroleum Coke Embedded in Cigarette Butts: All Waste-Derived Solar Evaporator for Effective Water Evaporation

Go Inoue, Alexandre Barras, Yunfei Ma, Ning Cao, Alexandre Fadel, Pascal Roussel, Mu Naushad, Sabine Szunerits, Rabah Boukherroub

Solar-driven interfacial evaporation is an eco-friendly solution for tackling the impending water scarcity the world is facing in our century. In this work, a solar-driven interfacial evaporator was prepared from cigarette butts loaded with petroleum coke powder (Filter-PetCoke), a by-product of…

Highly Conductive Tungsten Suboxide Nanotubes

Cécile Huez, Maxime Berthe, Florence Volatron, Jean-Michel Guigner, Dalil Brouri, Lise-Marie Chamoreau, Benoît Baptiste, Dominique Vuillaume, Anna Proust

We demonstrate a high electron conductivity (> 10^2 S/cm and up to 10^3 S/cm) of tungsten suboxide W18O(52.4-52.9)(or equivalently WO(2.91-2.94)) nanotubes (2 to 3 nm in diameter, ca. micrometer long). The conductivity is measured in the temperature range 120 to 300K by a four probe scanning…
