Spark Plasma Sintering and tribological behavior of Ti3SiC2–Ti5Si3–TiC composites

Abdessabour Benamor, Youcef Hadji, Nabil Chiker, Adel Haddad, Bendiba Guedouar, Mohamed Labaiz, Maamar Hakem, Arnaud Tricoteaux, Christelle Nivot, Jean-Pierre Erauw, Riad Badji, Mohamed Hadji

Herein, we study the effect of TiC content on the tribological behavior of four Ti3SiC2/Ti5Si3/TiC composites, prepared through Spark Plasma Sintering. The tribological properties were investigated under dry sliding, against Al2O3 counterpart at room temperature, under different normal loads and…

Nanotechnology to improve the performances of hydrodynamic surfaces

Ali Ahmed Alshehri, Philippe Champagne, Laurent Keirsbulck, El Hadj Dogheche

ure continues to inspire scientists to adapt solutions in order to satisfy human needs, mainly in the maritime domain with metallic surface corrosion and its mechanical friction. In this research, the source of innovation comes from the lotus leaf and its well-known super-hydrophobicity. In this…

Open-celled silicon carbide foams with high porosity from boron-modified polycarbosilanes

Charlotte Durif, Mélanie Wynn, Maxime Balestrat, Giorgia Franchin, Young-Wook Kim, Anne Leriche, Philippe Miele, Paolo Colombo, Samuel Bernard

Open-Celled silicon carbide (SiC) foams were prepared from a mixture of a boron-modified polycarbosilane as a preceramic polymer and poly(methymetacrylate) (PMMA) microbeads as sacrificial agents. The process consists in the cross-linking of the liquid allylhydridopolycarbosilane (AHPCS, SiC…

Minimal Lagrangian submanifolds of the complex hyperquadric

Haizhong Li, Hui Ma, Joeri van Der Veken, Luc Vrancken, Xianfeng Wang

We introduce a structural approach to study Lagrangian submanifolds of the complex hyperquadric in arbitrary dimension by using its family of non-integrable almost product structures. In particular, we define local angle functions encoding the geometry of the Lagrangian submanifold at hand. We…

The Directed Spanning Forest in the hyperbolic space: extended version

Lucas Flammant

The Euclidean Directed Spanning Forest (DSF) is a random forest in R d introduced by Baccelli and Bordenave in 2007 and we introduce and study here the analogous tree in the hyperbolic space. The topological properties of the Euclidean DSF have been stated for d = 2 and conjectured for d ≥ 3 (see…

Sensitivity range optimization of surface acoustic wave humidity ultrasonic sensors incorporating a polyvinyl alcohol (PVA) layer

Saliou Ndao, Marc Duquennoy, Christian Courtois, Mohammadi Ouaftouh, Mohamed Rguiti, Nikolay Smagin

In this paper, Surface Acoustic Wave (SAW) delay line (DL) based humidity sensors are optimized. These sensors comprise two ultrasonic interdigital transducers (IDT) for generating and detecting SAW. The SAWs propagate along a piezoelectric substrate covered with a polyvinyl alcohol (PVA) layer…

Dielectric, ferroelectric, piezoelectric properties, and impedance spectroscopy of (Ba 0.85 Ca 0.15 )(Ti 0.9 Zr 0.1 )O 3 -x% (K 0.5 Bi 0.5 )TiO 3 lead-free ceramics

Naima Zidi, Ahcène Chaouchi, Mohamed Rguiti, Yannick Lorgouilloux, Christian Courtois

The influence of (K0.5Bi0.5)TiO3 on structure, microstructure and piezoelectric properties of (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 (BCTZ) piezoelectric ceramics was investigated. Impedance spectroscopy was used to get better understanding of the electrical properties of the materials as a function of…
