This Sample seems to be good enough! Assessing Coverage and Temporal Reliability of Twitter's Academic API [PDF]
arXiv, 2022 Because of its willingness to share data with academia and industry, Twitter has been the primary social media platform for scientific research as well as for consulting businesses and governments in the last decade. In recent years, a series of publications have studied and criticized Twitter's APIs and Twitter has partially adapted its existing data ...

Angewandte Chemie International Edition, Accepted Article.Molecular machines rely on their capacity to exploit non‐equilibrium processes to perform work. However, the development of these non‐equilibrium processes, such as molecular ratchets, is still in its early stages. Here, we report a diazocine‐containing ligand (L) harbouring two distinct chelating coordination sites that can self‐sort into dinuclear ...
