New paper out, High-pressure crystallisation of Isobutyronitrile pubs.acs.org/doi/10.1021/..., nice results from the UWA and Synchrotron team that show this small molecule crystallises into the same structure as at low temperatures. There's some lovely calculations that explain why this may be.

arXiv will no longer accept review articles and position papers unless they have been accepted at a journal or a conference and complete successful peer review. This is due to being overwhelmed by a hundreds of AI generated papers a month. Yet another open submission process killed by LLMs.
