Blockchain-Based Collaborative Certificate Revocation Systems Using Clustering

Ahmed Didouh, Houda Labiod, Yassin El Hillali, Atika Rivenq

Despite the decisive contribution of intelligent transport systems in road safety, they also open new vulnerabilities to cyber-attacks, particularly vehicle position-linked attacks. For that reason, centralized systems are becoming increasingly vulnerable to the growth of the connected-vehicle...

The good, the bad and the ugly polishing: Effect of abrasive size on standardless EDS analysis of Portland cement clinker’s calcium silicates

Vincent Thiéry, Emmanuel Dubois, Séverine Bellayer

Standardless Energy dispersive spectroscopy (EDS) on polished samples of Portland cement clinker is routinely performed both for unhydrated phases as well as in cement pastes. Typically, the calcium to silica ratio is investigated. EDS analyses are highly dependent on the polishing quality of the...

Switchability of a single port SAW resonator using the electrical Bragg band gap

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, Anne-Christine Hladky

A proof of concept of a new solution for achieving tunable SAW components based on the electrical Bragg band gap concept developed for piezoelectric phononic crystals is presented on a SAW resonator on a LiNbO3 substrate. In this work, it is shown that for a fixed geometry, it is possible to shift...

Towards highly efficient high power X‐band AlN/GaN MIS HEMTs operating above 50V

Kathia Harrouche, Sri Saran Vankatachalam, François Grandpierron, Etienne Okada, F Medjdoub

We report on AlN/GaN MISHEMT technology on SiC substrate for X-band applications. Transistors with 100 nm gate lengths deliver a high off-state breakdown voltage above 180V and 110 V in semi-on state. RF small signal measurements up to a drain bias (VDS) as high as 70V for two different gate...

Elaboration and characterization of porous ultrathin gold films grown by ion beam assisted deposition

Abdelhanin Aassime, Marc Duquennoy, Frédéric Hamouda, Tahar Kadi, Frédéric Mahut, Mohammadi Ouaftouh

The growth of ultrathin gold layers on a silicon substrate is performed with an unconventional ion beam assisted deposition. In this setup, evaporated gold flow and ion beam flux are perpendicular. 5 and 10 nm thick gold were deposited on tilted samples with the assistance of an argon ion beam at...

Can classical surface plasmon resonance advance via the coupling to other analytical approaches?

David Geilfuss, Rabah Boukherroub, Jakub Dostalek, Wolfgang Knoll, Jean-Francois Masson, Antje Baeumner, Sabine Szunerits

For nearly 40 years, surface plasmon resonance (SPR) analysis has been used to better understand the binding interaction strength between surface immobilized bioreceptors and the analytes of interest. The advantage of surface plasmon resonance, over other affinity sensing approaches such as Western...

Wafer-level vapor cells filled with laser-actuated hermetic seals for integrated atomic devices

Vincent Maurice, Clément Carlé, Shervin Keshavarzi, Ravinder Kumar Chutani, Samuel Queste, Ludovic Gauthier-Manuel, Jean-Marc Cote, Rémy Vicarini, Moustafa Abdel Hafiz, Rodolphe Boudot, Nicolas Passilly

Atomic devices such as atomic clocks and optically-pumped magnetometers rely on the interrogation of atoms contained in a cell whose inner content has to meet high standards of purity and accuracy. Glass-blowing techniques and craftsmanship have evolved over many decades to achieve such standards...

Nanostructures wetting evaluation using ultra high frequency ultrasound

Abbas Salhab, Julien Carlier, Malika Toubal, Pierre Campistron, Marc Neyens, Bertrand Nongaillard, V. Thomy

Ultrasounds are a great tool for defects detection particularly for optically non-transparent materials. Hence, working at very high frequency (#GHz) allows the detection of nanoscale contact defects at the interface between two materials and especially in the presence of air, which has negligible...

The out-of-field dose in radiation therapy induces delayed tumorigenesis by senescence evasion

Erwan Goy, Maxime Tomezak, Caterina Facchin, Nathalie Martin, Emmanuel Bouchaert, Jerome Benoit, Clementine de Schutter, Joe Nassour, Laure Saas, Claire Drullion, Priscille Brodin, Alexandre Vandeputte, Olivier Molendi-Coste, Laurent Pineau, Gautier Goormachtigh, Olivier Pluquet, Albin Pourtier, Fabrizio Cleri, Eric Lartigau, Nicolas Penel, Corinne Abbadie

A rare but severe complication of curative-intent radiation therapy is the induction of second primary cancers. These cancers preferentially develop not inside the planning target volume (PTV) but around, over several centimeters, after a latency period of 1–40 years. We show here that normal human...

Electrochemical H2 Production using Polypyrazole based Zinc(II) Complex in Alkaline Medium

Mohamed Ibrahim, Gaber A.M. Mersal, Ahmed Fallatah, Rabah Boukherroub, Safaa Abdou, Mohammed Amin

A zinc(II) complex of polypyazole containing ligand namely, [Tp*ZnCl] (Zn1) {Tp* = tris(3,5-dimethylpyrazolyl)borate}, along with its zinc(II) bound hydroxo complex [Tp*Zn–OH] (Zn2) were synthesized and characterized by FT-IR, Raman, 1H NMR techniques and elemental analysis. In alkaline solution (0...
