ChemRxiv is now in Valency
Chemistry preprints now sit alongside PubMed, arXiv, and the entirety of the research corpus, searchable in one query.
We’re building Valency toward a single, unified corpus of science, one your AI can search and reason over in one pass. We have just added chemistry! Now, a search for battery electrolytes in Valency Bond pulls chemistry preprints from ChemRxiv right alongside materials science from arXiv and toxicology from PubMed.
On October 21, ChemRxiv, the preprint server for the chemical sciences, became a live source in Valency. As of this writing, that adds more than 46,000 chemistry preprints going back to August 2017, including about 9,400 posted so far this year. We index new ChemRxiv papers daily as with the rest of our collection.
ChemRxiv now sits alongside PubMed, arXiv, bioRxiv, medRxiv, PsyArXiv, SocArXiv, EarthArXiv and Valency Hub, nearly 45 million papers in all. You can now run searches restricted to ChemRxiv or let your LLM reason over the entire corpus intelligently. A citation graph of over 500 million works supports these searches.
This matters because breakthroughs rarely happen inside one field. They happen at the seams, like when a chemist finds the key idea in a materials science or mathematics paper that was never on their radar. With ChemRxiv in the same index as arXiv and PubMed, one query now crosses those seams, and the citation graph surfaces connections no single researcher has time to find.
ChemRxiv went live on the first day of the Open Scientific Intelligence (OSI) Hackathon. So far two participants who built chemistry projects with Valency Bond there have rapidly published their work on Valency Hub: a study of how deuteration shifts polymorph stability across 220 inorganic polymorph pairs, and TS Second Opinion, which catches and repairs mirror-image errors in machine-learned transition states.
This new source is now instantly available in any LLM connected to Valency Bond. Try some sample queries like:
- “Use Valency to find ChemRxiv preprints from the last 30 days on PFAS destruction, summarize the approaches, and link each paper.”
- “How has ‘self-driving laboratory’ grown on ChemRxiv compared with ‘machine learning’?”
- “Who posts most about CO2 electroreduction on ChemRxiv, and what else have they published?”
- “Use Valency to find ChemRxiv preprints from the past six months on [your topic], and show me related work from PubMed and arXiv.”
Valency Bond is free for individual users: get started here.
Happy researching!
