Validation and optimization of the ATMO-Street air quality model chain by means of a large-scale citizen-science dataset

Detailed validation of air quality models is essential, but remains challenging, due to a lack of suitable high-resolution measurement datasets. This is particularly true for pollutants with short-scale spatial variations, such as nitrogen dioxide (NO₂). While street-level air quality model chains can predict concentration...

Compliant Remote-Center-of-Motion Mechanism Optimized for Energy-Dispersive Spectroscopy

In-situ sample holders with double-tilting capabilities are used to insert and position samples inside a transmission electron microscope for dynamic imaging. However, the performance of these sample holders, regarding energy-dispersive X-ray spectroscopy (EDS) analysis, is not on par with their single-tilt counterparts. By analyzing the EDS...
