Quenching of excitons at grain boundaries in C60 thin films
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and therefore grain boundaries, impacts exciton dynamics in thin films of C60/Au(111) using time and angle-resolved photoemission spectroscopy (TR-ARPES). We find that films with multiple rotational domains exhibit shorter exciton lifetimes and evidence of exciton-exciton annihilation, even when one domain predominates. Scanni…

Thanks to this global monitoring system, which has been deployed for more than 20 years, millions of people in Japan and Russia were warned.

Following dismal results in Japan’s parliamentary elections,
there is a broad consensus among Japanese lawmakers and political analysts that
Prime Minister Shigeru Ishiba’s days are numbered.
No one, however, seems to have said that directly to Ishiba, who has vowed to stay on.
The current political crisis is the result of a July 20 election in Japan’s upper house -- the less-powerful chamber in parliament.
It has no direct role in determining the prime minister …

The First Compute Arms Race: the Early History of Numerical Weather Prediction
This paper traces the global race to apply early electronic computers to numerical weather prediction in the decades following World War Two. A brief overview of the early history of numerical weather prediction in the United States, United Kingdom, Sweden, Canada, and Japan is provided. Three critical factors that shaped the development of a national numerical weather prediction are identified: compute capabilities, institution building and state capacity, and talent. Several generalizable les…
