Ultrasonic Rainbow: A Meta‐Transducer for Frequency‐Selective Elastic Wave Control via Dithering‐Based Wavenumber Tuning

open access: yesAdvanced 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

DNA‐mimic for Specific Surface Functionalization of Zr‐MOFs for Bacterial Targeting

open access: yesAngewandte Chemie, EarlyView.
We introduce phosphotyrosine‐modified PNA as a superior, single‐step post‐synthesis surface coating for PCN‐222. The DNA mimic allows for controlled post‐functionalization with single‐stranded DNA for the attachment of protein moieties for bacterial targeting. ABSTRACT Nanosized metal–organic frameworks (MOFs) are versatile platforms used in biomedical

Help‐Seeking and Substance Use Among Police Staff After the 2018 Strasbourg Christmas Market Attack

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background The use of mental health services by police staff is usually low. After the 2018 attack on the Strasbourg Christmas market, police officers exposed to psychotraumatic risks were found to have a higher PTSD risk. This study aims to describe the help‐seeking and substance use by police staff after the attack.
