Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Advanced Intelligent Systems, EarlyView.A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

The relation of nocturnal exposure to aircraft noise and aircraft noise-induced insomnia with blood pressure [PDF]
Polish Archives of Internal Medicine, 2020 Nighttime environmental noise exposure leads to unconscious stress reactions and autonomic arousals. These may disturb overnight sleep and the diurnal blood pressure (BP) profile, contributing to an increased risk of developing hypertension.This study aimed to investigate the effects of chronic nighttime exposure to aviation noise on sleep disturbances
