Acoustic Metamaterials in Aeronautics

Applied Sciences, 2018
Metamaterials, man-made composites that are scaled smaller than the wavelength, have demonstrated a huge potential for application in acoustics, allowing the production of sub-wavelength acoustic absorbers, acoustic invisibility, perfect acoustic mirrors

Synergistic Enhancement of Electrical‐Thermal Properties in KH550/G‐POSS Functionalized BN/Epoxy Composites for High‐Frequency Transformer Insulation

Advanced Science, EarlyView.
A BN@G‐POSS/EP nanocomposite is developed for high‐frequency transformer insulation in power electronic transformers. Through synergistic interface engineering, it simultaneously enhances thermal conductivity, reduces viscosity, and improves electro‐thermal stability.

Innovative Monitoring for Aeronautical Application Through Augmented Reality

Engineering Proceedings
The technologies grouped under the term Extended Reality (XR) are constantly evolving. Only fifty years ago, they were delegated to the science fiction strand and were not feasible except in the distant future; today, they are successfully used for ...

Layer‐Dependent Phonon Polaritons in hBN Resolved by Photo‐Induced Force Spectroscopy

Advanced Science, EarlyView.
Layer‐dependent phonon polariton resonances in hexagonal boron nitride are systematically investigated using photo‐induced force microscopy. The in‐plane resonance exhibits a blueshift, while the out‐of‐plane resonance shows a redshift with increasing thickness. These results establish layer number as a key parameter for tuning polaritonic responses in

Mobilisation du corps et simulation : comment susciter la transformation des pratiques professionnelles ?

Activités
How can we support professionals who are reluctant to change their practices, even when those practices have negative impacts on work performance and health? Fostering the transformation of professional practices remains a major challenge.

Bioinspired Passive Flow Routing to Mitigate Thrombosis in Prosthetic Heart Valves and Cardiovascular Devices

Advanced Science, EarlyView.
Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude
