Polymer Photonic Crystal Membrane for Human Body Thermoregulation

Mohamed Boutghatin, Salim Assaf, Michèle Carette, V. Thomy, Abdellatif Akjouj, Bahram Djafari-Rouhani, Yan Pennec

We study the optical properties of a polymer photonic membrane to keep the human body in thermal comfort. We show theoretically that the periodic structuration of the membrane with air holes modulates the optical response in the Mid-Infrared range. We found that the modulation of the optical…

Exploring the capabilities of scanning microwave microscopy to characterize semiconducting polymers

Olivier Douhéret, Didier Theron, David Moerman

Standing at the meeting between solid state physics and optical spectroscopy, microwave characterization methods are efficient methods to probe electronic mechanisms and mesoscopic transport in semiconducting polymers. Scanning microwave microscopy, augmented with a Mach-Zehnder interferometer…

Modelling and evaluation of carbon based foam thermoacoustic effect for effective sound generation in fluids, Analyse théorique et expérimentale de l'efficacité de mousse de carbone pour génération acoustique dans des milieux visqueux

Pierre, Henri Guiraud

Electroacoustic transducers along with piezoelectric devices are the most widely used methods for acoustic sound generation in gas and liquids. A mechanical movement of a membrane induces fluid vibration thus creating an acoustic wave. The thermoacoustic process on the other hand uses fast paces…, Les transducteurs électroacoustiques ainsi que les dispositifs piézoélectriques sont les principales méthodes de génération acoustique dans un gaz ou un liquide. Un mouvement mécanique d’une membrane crée une vibration du fluide générant une onde acoustique. La thermoacoustique en revanche utilise…

Shape dynamics of rotating polygons on the surface of liquid nitrogen in a Leidenfrost state

Jacob S. Bach, Alexis Duchesne, Tomas Bohr

When liquid nitrogen is set into rotation in a warm pot, the surface, initially forming an axis symmetrical, toroidal shape, spontaneously re-structures into a series of rotating polygons with a diminishing number of corners, while slowing down. This spontaneous "ordering" occurs despite…

Asymmetric topological state in an elastic beam based on symmetry principle

Yabin Jin, Wan Wang, Bahram Djafari-Rouhani

The symmetric propagation of topological edge states in two-dimensional (2D) mechanical systems cannot be directly applied to a one-dimensional (1D) system such as a beam. In this work, we adopt symmetry principle of single- and double-sided pillared phononic beams to realize asymmetric…

Plasmon-driven electrochemical methanol oxidation on gold nanohole electrodes

Liuqing Pang, Alexandre Barras, Vladyslav Mishyn, Svetlana Heyte, Egon Heuson, Hamid Oubaha, Georgiana Sandu, Sorin Melinte, Rabah Boukherroub, Sabine Szunerits

Direct methanol oxidation is expected to play a central role in low-polluting future power sources. However, the sluggish and complex electro-oxidation of methanol is one of the limiting factors for any practical application. To solve this issue, the use of plasmonic is considered as a promising…
