Design of a thin-plate based tunable high-quality narrow passband filter for elastic transverse waves propagate in metals

J. Zhang, L. H. Zeng, C. L. Hu, W. S. Yan, Yan Pennec, N. Hu

For the elastic SV (transverse) waves in metals, a high-quality narrow passband filter that consists of aligned parallel thin plates with small gaps is designed. In order to obtain a good performance, the thin plates should be constituted by materials with a smaller mass density and Young’s modulus...

Spatiotemporal control of DNA-based chemical reaction network via electrochemical activation in microfluidics

Ievgen Kurylo, Guillaume Gines, Yannick Rondelez, Yannick Coffinier, Alexis Vlandas

In recent years, DNA computing frameworks have been developed to create dynamical systems which can be used for information processing. These emerging synthetic biochemistry tools can be leveraged to gain a better understanding of fundamental biology but can also be implemented in biosensors and...

Resolution Improvement Method for Non-Destructive Imaging with Near-Field Scanning Microwave Microscopy

Tianjun Lin, S. Gu, T. Lasri

In this paper we report a resolution enhancement method for non-destructive imaging application with near-field scanning microwave microscopy (NFMM). The technique proposed for the image processing is based on the combination of the position/signal difference (PSD) method and an adaptive robust...

Semi-analytical discontinuous Galerkin finite element method for the calculation of dispersion properties of guided waves in plates

Salah-Eddine Hebaz, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

The development of reliable guided waves inspection systems is conditioned by an accurate knowledge of their dispersive properties. The semi-analytical finite element method has been proven to be very practical for modeling wave propagation in arbitrary cross-section waveguides. However, when it...

Spacetime representation of topological phononics

Pierre A. Deymier, Keith Runge, Pierre Lucas, Jerome O. Vasseur

Non-conventional topology of elastic waves arises from breaking symmetry of phononic structures either intrinsically through internal resonances or extrinsically via application of external stimuli. We develop a spacetime representation based on twistor theory of an intrinsic topological elastic...

Cold remote plasma modification of wood: Optimization process using experimental design

Brigitte Mutel, Muriel Bigan

A Cold Remote (N-2 + O-2) Plasma (CRNOP) process was used in order to create new surface properties on various wooden samples. Two applications were studied and optimized using experimental design. The first one involved samples (fir, pine, beech and oak) treated by the CRNOP in order to increase...

Dielectric Characterization of Polylactic Acid Substrate in the Frequency Band 0.5-67 GHz

Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, T. Lasri

Polylactic acid (PLA) is a bio-based and biodegradable polymer currently used in a wide range of packaging, medical, and industrial applications. PLA is also envisaged for the development of sustainable products for general public, including electronic devices. For these applications, the knowledge...

Colloidal nanocrystals as LEGO® bricks for building electronic band structure models

Athmane Tadjine, Christophe Delerue

Abstract The synthesis of self-assembled semiconductor nanocrystal (NC) superlattices using oriented attachment recently became a flourishing research topic. This technique already produced remarkable forms of NC superlattices, such as linear chains, mono and multilayer square lattices, and...

Gallium nitride MEMS resonators: how residual stress impacts design and performances

Christophe Morelle, Didier Theron, Joff Derluyn, Stefan Degroote, Marianne Germain, Victor Zhang, Lionel Buchaillot, Bertrand Grimbert, Pascal Tilmant, Francois Vaurette, Isabelle Roch-Jeune, Virginie Brandli, Vanessa Avramovic, Etienne Okada, Marc Faucher

Starting from Gallium Nitride epitaxially grown on silicon, pre-stressed micro-resonators with integrated piezoelectric transducers have been designed, fabricated, and characterized. In clamped-clamped beams, it is well known that tensile stress can be used to increase the resonant frequency. Here...
