Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2017ja024274

Abstract: We propose a targeted observation strategy, based on the influence matrix diagnostic, that optimally selects where additional observations may be placed to improve ionospheric forecasts. This strategy is applied in data assimilation observing system experiments,… read more here.

Published in 2024 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202401703

Abstract: The Zn─Sb binary system contains two high‐performing thermoelectric materials, namely the ordered ZnSb and the disordered Zn13Sb10. Both systems exhibit low thermal conductivity, which is speculated to originate from multicentre bonding within Zn2Sb2‐rhombi. Here, the… read more here.
