Unleashing the Power of a Double-Nanobody Sandwich Electrochemical Assay for Rapid Detection of Grapevine Fanleaf Virus

Subhankar Sahu, Sarah Dietrich, Rabah Boukherroub, Vianney Poignavent, Adrien Trolet, Hélène Scheer, Anne Cousin, Daniel Clesse, Gérard Demangeat, Sabine Szunerits, Christophe Ritzenthaler

Grapevine fanleaf virus (GFLV) is one of the most severe and widespread viruses affecting grapevines, causing significant economic losses by reducing crop quality and vineyard longevity. As no curative treatment exists, disease prevention relies essentially on prophylactic measures. The standard...

Pyrochlore nanomineralogy questions the immobility of niobium during tropical weathering

Quentin Bollaert, Mathieu Chassé, Nicolas Menguy, Corentin Le Guillou, Artur Bastos Neto, David Troadec, Laurence Galoisy, Georges Calas

The origin of the mobility of low-solubility elements such as niobium during supergene weathering remains elusive, despite growing evidence, especially in strongly weathered regolith. In the critical zone, the low mobility of these high field strength elements (HFSEs) is assigned to the resistance...

Development and validation of a 2D Mason model for ultrasonic transducer arrays: A simplified approach simulating crosstalk and dissipation mechanisms

Anouar Boujenoui, Abdelmajid Bybi, Hayat Reskal, Hassna Khalfi, Lahoucine Elmaimouni, Anne-Christine Hladky-Hennion

Piezoelectric elements arranged in 1D or 2D configurations are commonly used in ultrasonic transducer arrays for medical imaging and non-destructive testing (NDT) applications. These arrays are usually modeled using complex 2D or 3D numerical methods. Based on the equivalent circuit approach...

PCB-Based Hybrid Series/Corporate-Fed 4 × 4 D-Band Phased Array With Wide-Angle Scanning

Kamil Yavuz Kapusuz, Samuel Rimbaut, Siddhartha Sinha, Joris van Driessche, Ad Reniers, A. Bart Smolders, Pascal Szriftgiser, Guillaume Ducournau, Hendrik Rogier, Sam Lemey

Sixth generation (6G) wireless networks are envisioned to include aspects of energy footprint reduction (sustainability), besides those of network capacity and connectivity, at the design stage. This paradigm change requires radically new physical layer technologies. Notably, the integration of...

FragCast: A Scalable BLE-based OTA Framework for Constrained IoT Devices

Ebenezer Djafsia Souboura, Damien Sambo, Paul Dayang, Michel Vianney Komguep, Laurent Clavier

The proliferation of constrained Internet of Things (IoT) devices requires scalable Over-the-Air (OTA) firmware update mechanisms. Conventional approaches, predominantly based on one-to-one communication such as Bluetooth Low Energy (BLE) Device Firmware Update (DFU), suffer from a scalability...

Measurement of magnetic loss in ferromagnetic lamella using high sensitivity piezo-magnetic surface acoustic wave sensor

Othmane Marbouh, Gaetan Sanchez, Aurélien Mazzamurro, Mohamed Boutghatin, Olivier Bou Matar, Yannick Dusch, Romain Viard, Aymen Ammar, Phillipe Pernod, Nicolas Tiercelin, Abdelmounaim Tounzi, Abdelkader Benabou, Abdelkrim Talbi

Magnetic field sensors combining surface acoustic waves (SAW) and magnetostrictive thin films have shown promising sensitivity in laboratory studies, but their translation into real-world applications has remained limited. In this work, we report the first practical deployment of a shear-horizontal...

High-Sensitivity Love Wave SAW Sensors with Composite Guiding Layer and Phononic Crystal Cavity

A. Leschiutta, G. Eybert-Bouillier, Othmane Marbouh, O. Bou-Matar, V. Mortet, A. Talbi

In Love-wave-based biosensors, the most widely used architecture is the delay-line configuration, in which the sensing function is achieved by functionalizing the acoustic propagation path. This approach offers high robustness and compatibility with liquid-phase operation, making it particularly...
