Thermal Stability of Oleate‐Stabilized Gd2O2S Nanoplates in Inert and Oxidizing Atmospheres

Clément Larquet, D. Hourlier, Anh-Minh Nguyen, Almudena Torres-Pardo, Andrea Gauzzi, Clément Sanchez, Sophie Carenco

Capping ligands play an important role in the chemistry of nanoparticles synthesized with organic surfactants. This is relevant to a number of device applications where heating may cause major modifications of crystalline nanoparticles including amorphization, surface rearrangements or sintering....

Impact of Measurement Methods over the Characterization of Transient Electromagnetic (EM) Signals above 2 GHz in a Railway Environment

Grecia Romero, Virginie Deniau, Eric Pierre Simon

In order to offer on-board Internet access on trains a Wi-Fi and LTE connection are required. These communicationsystems have to take into account electromagnetic (EM) interferences present in the railway environment in the 2 GHz frequency band since this is a frequency band in which LTE and Wi-Fi...

Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals

Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present the realization of the topological valley-protected zero-order antisymmetric (A 0) or symmetric (S 0) and zero-order shear-horizontal (SH 0) Lamb waves at different domain walls based on topologically distinct asymmetric double-sided pillared phononic crystals. The elastic periodic...

Design of a four-branch optical power splitter based on gallium-nitride using rectangular waveguide coupling for telecommunication links

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, El Hadj Dogheche

This paper reports design of a simple four-branch optical power splitter using five parallel rectangular waveguides coupling in a gallium-nitride (GaN) semiconductor/sapphire for telecommunication links. The optimisation was conducted using the 3D FD-BPM method for long wavelength optical...

Evaluation of the hydrophobic properties of latex microspheres and <em>Bacillus</em> spores. Influence of the particle size on the data obtained by the MATH method (microbial adhesion to hydrocarbons)

Christine Faille, Christelle Lemy, Audrey Allion-Maurer, Farzam Zoueshtiagh

The current experimental study investigates the influence of latex microsphere particles' size on the assessment of their hydrophilic/hydrophobic character, using the method known as “Microbial Adhesion to Hydrocarbons” (MATH). Since bacteria surfaces often change according to the environment...

Chapter 6 - One-dimensional magnonic crystals

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents examples of bulk and surface magnons of one-dimensional magnonic crystals, called also superlattices. The such man-made crystals considered here are grown out of semiinfinite stacks of two and also three different ferromagnetic slabs. Each slab is modeled by a simple cubic...

Ferroelectric multiple-valued logic units

Igor A. Luk'Yanchuk, Elena Zaitseva, Vitaly Levashenko, Miroslav Kvassay, Svitlana Kondovych, Yuri Tikhonov, Laurent Baudry, Anna Razumnaya

Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material implementation of MVL units basing on their ability to pin the polarization as a sequence of multi-stable states. Two...

The Influence of Microstructure on the Passive Layer Chemistry and Corrosion Resistance for Some Titanium-Based Alloys

Nader El-Bagoury, Sameh Ahmed, Ola Ahmed Abu Ali, Shimaa El-Hadad, Ahmed Fallatah, G. Mersal, Mohamed Ibrahim, Joanna Wysocka, Jacek Ryl, Rabah Boukherroub, Mohammed A. Amin

The effect of microstructure and chemistry on the kinetics of passive layer growth and passivity breakdown of some Ti-based alloys, namely Ti-6Al-4V, Ti-6Al-7Nb and TC21 alloys, was studied. The rate of pitting corrosion was evaluated using cyclic polarization measurements. Chronoamperometry was...
