Evaluation of the Impact of Transient Disturbances on Railway Signaling Systems Using an Adapted Time-Frequency Analysis Method

Mohamed Raouf Kousri, Virginie Deniau, Marc Heddebaut, S. Baranowski

As many other industrial environments, the railway electromagnetic environment is characterized by a large number of electromagnetic signals and disturbances. Among these, transient signals, with high energy level and wide frequency spectrum, represent an important threat to different signaling…, Comme beaucoup d'autres environnements industriels, l'environnement électromagnétique ferroviaire est caractérisé par un grand nombre de signaux électromagnétiques et de perturbations. Parmi ceux-ci, les signaux transitoires, avec un niveau d'énergie élevé et un large spectre de…

Interaction between Cr-bearing pigments and transparent glaze: A transmission electron microscopy study

Louisiane Verger, Olivier Dargaud, Nicolas Menguy, David Troadec, Laurent Cormier

Spinel ZnAl2O4 and corundum Al2O3 doped with chromium are used as pink pigments in porcelain glazes. However, alteration of the color can occur during firing, and the resulting glaze appears brown and green respectively, instead of the expected pink. To investigate the mechanism of color change,…

Supramolecular self-assembly on the B-Si(111)-(√3x√3) R30° surface: From single molecules to multicomponent networks

Younes Makoudi, Judicaël Jeannoutot, Frank Palmino, Frédéric Cherioux, Guillaume Copie, Christophe Krzeminski, Fabrizio Cleri, B. Grandidier

Understanding the physical and chemical processes in which local interactions lead to ordered structuresis of particular relevance to the realization of supramolecular architectures on surfaces. While spectacularpatterns have been demonstrated on metal surfaces, there have been fewer studies of the…

Nanomaterials for transdermal drug delivery: beyond the state of the art of liposomal structures

Roxana Jijie, Alexandre Barras, Rabah Boukherroub, Sabine Szunerits

A wide range of biomedical materials have been proposed to meet the different needs for controlled oral or intravenous drug delivery. The advantages of oral delivery such as self-administration of a predetermined drug dose at defined time intervals makes it the most convenient means for the…

Visible light assisted hydrogen generation from complete decomposition of hydrous hydrazine using rhodium modified TiO2 photocatalysts

Pawan Kumar, Anurag Kumar, Clemence Queffelec, Dietrich Gudat, Qi Wang, Suman L. Jain, Rabah Boukherroub, Sabine Szunerits

Hydrogen is considered to be an ideal energy carrier, which produces only water when combined with oxygen and thus has no detrimental effect on the environment. While the catalytic decomposition of hydrous hydrazine for the production of hydrogen is well explored, little is known about its…

Acoustic Energy Transfer by Friction Induced Vibrations

Giovanna Lacerra, F. Massi, Eric Chatelet, Emmanuel Moulin

Friction-induced vibrations are often investigated for their unwanted effects, such as surface wear and dynamic instabilities. This article focuses on the exploitation of friction-induced vibrations to transfer the energy between different acoustic fields by an interface under frictional contact.…

Sputtered titanium carbide thick film for high areal energy on chip carbon-based micro-supercapacitors

Manon Létiche, Kevin Brousse, Arnaud Demortiere, Peihua Huang, Barbara Daffos, Sébastien Pinaud, Marc Respaud, Bruno Chaudret, Pascal Roussel, Lionel Buchaillot, Pierre-Louis Taberna, Patrice Simon, Christophe Lethien

The areal energy density of on-chip micro-supercapacitors should be improved in order to obtain autonomous smart miniaturized sensors. To reach this goal, high surface capacitance electrode (>100 mF cm−2) has to be produced while keeping low the footprint area. For carbide-derived carbon (CDC)…
