Orthogonal Staggered Alignment of Molecular Chains in Aramid Whiskers: A Game‐Changer for Sustainable, High‐Performance Composites

open access: yesMacromolecular Rapid Communications, EarlyView.
Poly(p‐benzamide) whiskers with orthogonal chain alignment form prismatic single crystals, enabling uniform dispersion and high crystallinity. This architecture enhances composite thermal stability, modulus, and dimensional integrity, offering a sustainable, lightweight alternative to inorganic fillers and redefining polymer crystallography through ...

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Impacts of atmospheric river reconnaissance dropsondes on ECMWF Integrated Forecasting System precipitation forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Impacts of Atmospheric River Reconnaissance dropsonde observations on precipitation forecasts over the U.S. West Coast are examined in the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), using observing‐system experiments.

The benefits and challenges of using dense Mode‐S aircraft winds at ECMWF

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In November 2022 ECMWF stopped using Mode‐S winds because their very high density in central Europe caused problems for the assimilation system. The data were reintroduced operationally in November 2023 combined with an improved aircraft thinning algorithm.
