Facile Charge Transfer between Barbituric Acid and Chloranilic Acid over g-C3N4: Synthesis, Characterization and DFT Study

Gaber Mersal, Mohamed Ibrahim, Mohammed Amin, Amine Mezni, Nasser Mostafa, Sarah Alharthi, Rabah Boukherroub, Hamdy El-Sheshtawy

The molecular complexes between barbituric acid (BU) and chloranilic acid (ChA) over graphitic nitride (g-C3N4) are investigated. The molecular complexes and the nanocomposite were investigated both in solid state and in methanol. The solid complexes and the corresponding nanocomposite were...

Topological surface wave metamaterials for robust vibration attenuation and energy harvesting

Xinyue Wu, Yabin Jin, Abdelkrim Khelif, Xiaoying Zhuang, Timon Rabczuk, Bahram Djafari-Rouhani

We propose topological metamaterials working in Hertz frequency range, constituted of concrete pillars on the soil ground in a honeycomb lattice. Based on the analog of the quantum valley Hall effect, a non-trivial bandgap is formed by breaking the inversion symmetry of the unit cell. A topological...

A first outlook of sputtered FeWO₄ thin films for micro-supercapacitor electrodes

Gaëtan Buvat, Antonella Iadecola, Florent Blanchard, Thierry Brousse, Pascal Roussel, C. Lethien

The next generation of Internet of Things devices requires micro-supercapacitors operating at high voltage which is difficult to achieve using symmetrical design. Thus, their fabrication in an asymmetric configuration is mandatory. While MnO2 is well-established as positive electrode, the scarcity...

On The Necessity of Multiphysics Simulation Experiments in MEMS Teaching

Jinying Zhang, Wei-Jiang Xu, Xianmei Wu

Microelectromechanical system (MEMS) is an interdisciplinary research and education field. The multiphysics simulation can make the abstract theory on MEMS design concrete and improve the learning efficiency. A MEMS course design is presented in this paper. The content consists of fundamental...

Hierarchical large-scale elastic metamaterials for passive seismic wave mitigation

M. Miniaci, Nesrine Kherraz, Charles Croënne, Matteo Mazzotti, Maryam Morvaridi, Antonio S. Gliozzi, Miguel Onorato, Federico Bosia, Nicola Maria Pugno

Large scale elastic metamaterials have recently attracted increasing interest in the scientific community for their potential as passive isolation structures for seismic waves. In particular, so-called “seismic shields” have been proposed for the protection of large areas where other isolation...

18 - Optical Tamm States in Semiinfinite Layered Photonic Crystals

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani, Gaëtan Lévêque

We investigate localized and resonant optical waves associated with a semiinfinite one-dimensional photonic crystal constructed by two different layers (1 and 2) and terminated with a cap layer. In this chapter, we present an analytic determination of the response function (Green's function)...

12 - Serial Loop Structures: Photonic Bandgaps, Confined, Cavity, and Surface Modes

El Houssaine El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, L. Dobrzynski

In this chapter, we investigate the electromagnetic band structure, transmission, phase time, as well as confined and surface modes in a one-dimensional photonic structure made of loops pasted together with segments of finite length. In this serial loop structure, the loops and segments are...

10 - Photonic Demultiplexers Based on Fano and Induced Transparency Resonances

El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani, Abdelkrim Talbi, L. Dobrzynski

In this chapter, we give an analytical and experimental demonstration of the possibility to realize a simple photonic demultiplexer based on Fano and electromagnetically induced transparency resonances. The demultiplexer consists on a Y-shaped waveguide with an input line and two output lines. Each...
