Theoretical and numerical modeling of ultrasonic scattering in polycrystalline materials: from elongated grains to columnar grains

For nondestructive evaluation using laser ultrasonics technique, it is of great interest to study the scattering of ultrasonic waves in polycrystalline materials, which contains useful microstructural information that can be used in inversion…

Engineering Polymer Interfaces: A Review toward Controlling Triboelectric Surface Charge

Abstract Contact electrification and triboelectric charging are areas of intense research. Despite their low ability to accept or donate electrons, polymer insulator based triboelectric nanogenerators have emerged as highly efficient mechanical‐to…

High frequency attenuation of elastic waves transmitted at an angle through a randomly-fluctuating horizontally-layered slab

This paper is concerned with the modeling of elastic waves travelling at small incidence angles through a randomly-fluctuating horizontally-layered slab, in regimes where the wavelength is small compared to the thickness of the slab. The wave…

A simple and efficient process for the synthesis of 2D carbon nitrides and related materials

Abstract We describe here a new process for the synthesis of very high quality 2D Covalent Organic Frameworks (COFs), such a C 2 N and CN carbon nitrides. This process relies on the use of a metallic surface as both a reagent and a support for the…

Toward the development of a three-step coupled modeling for the assessment of air leakage ratio through cracked reinforced concrete walls

Every ten years, the containment buildings of nuclear reactors are tested through a 4-bar relative pressure loading with dry air in order to characterize the leakage ratio through the walls. The experimental and numerical studies (MAEVA, VERCORS,…

Role of Cu‐doping in <scp>CdTe</scp> thin films: Experiments and simulations

Due to its outstanding physical properties, CdTe is used to fabricate high efficiency solar cells. However, its high work function poses a challenge, and hence, to fabricate an efficient CdTe-based solar cell, Cu-doping may be useful. Here, we…
