Rapid characterisation of millimetre-tall vertically aligned carbon nanotube arrays: growth optimisation by tuning the catalyst film thickness

Xinghai Zhao, Johannes Eduard Stubbe, Jin Chuen Kenneth Ho, Putu Andhita Dananjaya, Wen Siang Lew, Philippe Coquet, Beng Kang Tay

This study aims to establish a quick and sustainable approach for optimising the growth of millimetre-tall vertically aligned carbon nanotube (VACNT) arrays through simple catalyst tuning. To achieve this swiftly, a rapid and handy characterisation protocol is essential. Herein, we propose and…

Direct impedance eduction of acoustic liners in multimodal ducts with shear flows

Jinyue Yang, Thomas Humbert, Joachim Golliard, Gwénaël Gabard

Impedance eduction of acoustic liners with flow is usually performed under the assumption of a uniform mean flow and in the presence of an incident plane wave. However, recent studies have demonstrated that shear flow significantly influences the propagation of sound waves and their interaction…

Wide-Angle Reflective Terahertz Beam Steering Metasurface Based on Cross-Polarization Conversion

Mengyao Li, Zhonghua Gu, Cheemalamarri Hemanth Kumar, Nanhan Liu, Frédéric Dutin, Pascal Szriftgiser, Guillaume Ducournau, Prakash Pitchappa

The terahertz (THz) frequency range is considered an important spectrum for future six-generation communication. However, the high propagation losses and poor penetration inherent to THz waves restricted its development. Wavefront manipulation techniques for beam steering to redirect the…

Nanoscale Evidence of Junction‐Limited Transport in Ti 3 C 2 T x MXene

Oriane de Leuze, Maxime Berthe, Sophie Hermans, Benoît Hackens

ABSTRACT Understanding charge transport in networks of 2D crystals is essential for developing reliable applications such as chemiresistors or electromagnetic shields. For this purpose, intra‐ and inter‐flake contributions to the network resistance must be disentangled. MXenes such as Ti 3 C 2 T x…

Optimisation of a non contact coil / magnet actuator: geometry, nonlinearities and thermal heating

Marguerite de La Bigne, Eric Cattan, Sofiane Ghenna, Sébastien Grondel, Olivier Thomas

This article presents the optimisation of an electromagnetic actuator composed of a toroidal coil and a cylindrical magnet positioned along the coil’s axis that may be used for non-contact measurement of excitation of structures, for vibration testing, electromagnetic shunts or energy harvesting.…

Dynamics of the harmonic acoustic pneumatic source for active control of time-varying tonal noise

Alexandre Schiavini, Philippe Micheau, Pierre Grandjean, Gwénaël Gabard, Thomas Humbert

The Harmonic Acoustic Pneumatic Source (HAPS), a mechanical airflow modulator, is a promising alternative to loudspeakers as secondary sources for the active control of harmonic noise, thanks to its ability to generate high sound pressure levels and to precisely control signal frequency, phase, and…
