Silicon nanowire-hydrogenated TiO2 core-shell arrays for stable electrochemical micro-capacitors

Yasmina Bencheikh, Ahmed Addad, Yannick Coffinier, Umesh Kumar, Pascal Roussel, Sabine Szunerits, Toufik Hadjersi, Mohammed Amin, Seddik El Hak Abaidia, Rabah Boukherroub

In this paper, we fabricated silicon nanowire-TiO2 core-shell arrays in a two-step process. First, silicon nanowire arrays (SiNW) were prepared in HF/AgNO3 aqueous solution using metal-assisted chemical etching of bulk silicon. Then, atomic layer deposition (ALD) technique was applied to coat a 20...

Fortran Package Manager: Toward a rich ecosystem of Fortran packages

Sebastian Ehlert, Ondřej Čertík, Milan Curcic, Jakub Jelínek, Laurence Kedward, Vincent Magnin, Emanuele Pagone, Brad Richardson, John Urban

Fortran is the oldest programming language still in use today, targeting high-performance scientific and engineering applications. Traditionally, Fortran software has used build systems that are not portable or are difficult to use or extend. This has presented a significant barrier to entry for...

Periodic Structures, Irreducible Brillouin Zone, Dispersion Relations and the Plane Wave Expansion Method

Jerome O. Vasseur

The Plane Wave Expansion (PWE) method allows the calculation of dispersion curves, i.e., the relation linking the frequency to the wave number for any propagating mode of periodic structures made of elastic materials such as phononic crystals. The method is relatively easy to implement numerically...

An Analytical Model of the End-to-End Performance for Linear Video Delivery Under Bandwidth Constraints

Anthony Trioux, M Gharbi, François-Xavier Coudoux, Patrick Corlay

Recently, Linear Video Coding and Transmission (LVCT) schemes have been proposed as an alternative to traditional video transmission schemes, the latter experiencing cliff-effect [3] in wireless error-prone environments. In this paper, we propose an analytical model to estimate/predict the end-to-...

Effect of Coupled Helmholtz Resonators on Sound Control

R. Sabat, Gaëtan Lévêque, Yan Pennec, D. Torrent, Bahram Djafari-Rouhani

In our work, we are interested in the effect of coupling between Helmholtz resonators using the finite element model. We show that the coupling between two spheres leads to two peaks of resonance at low frequencies. One of them is symmetric and corresponds to a mono-polar breathing mode. The second...

Evanescent Coupling Between Aluminum Pillars

Rock Akiki, Yan Pennec, Adnane Noual, Eric Lheurette, Bernard Bonello, Bahram Djafari-Rouhani

We theoretically investigate with the help of the finite element method, the interaction between aluminum pillars erected on top of a semi-infinite substrate of silicon in the low frequency range. Our interest is to control and manipulate the propagation of surface acoustic waves (SAW) along the...

Ultra-high areal capacitance and high rate capability RuO2 thin film electrodes for 3D micro-supercapacitors

Bouchra Asbani, Gaëtan Buvat, Jeremy Freixas, Marielle Huvé, David Troadec, Pascal Roussel, Thierry Brousse, Christophe Lethien

To power the next generation of miniaturized electronic devices, 3D micro-supercapacitors are a new class of millimeter scale electrochemical capacitors with superior storage performance than their planar counterparts. Nevertheless, it is mandatory to carefully match the dimensions of the 3D...

Application of Combined Geophysical Methods for the Examination of a Water Dam Subsoil

Tomislaw Golebiowski, Bogdan Piwakowski, Michał Ćwiklik, Antoni Bojarski

The paper presents the results of geophysical measurements that were carried out in the vicinity of the water dam/water reservoir supplying the city of Bielsko-Biala with drinking water. The measurements were performed in order to non-invasively detect faults, fractured zones and areas filled with...

Study of Electrode Locations for Joint Acquisition of Impedance- and Electro-cardiography Signals

Margus Metshein, Antoine Gautier, Benoit Larras, Antoine Frappé, Deepu John, Barry Cardiff, Paul Annus, Raul Land, Olev Martens

ICG (impedance cardiography) and ECG (electrocardiography) provide important indications about functioning of the heart and of overall cardiovascular system. Measuring ICG along with ECG using wearable devices will improve the quality of health monitoring, as ICG points to important hemodynamic...
