The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

Contactless Detection of Giant Helicity‐Dependent Photovoltage in Chiral 2D Perovskites

open access: yesSmall, EarlyView.
A novel contactless probe—circularly polarized time‐resolved surface photovoltage spectroscopy is demonstrated to evaluate helicity‐dependent charge separation dynamics without the need for electrical contacts. Application of this novel methodology to chiral 2D perovskites reveals giant transient surface photovoltage anisotropy.
