An inspiring conference in St. Anton sparked a project: turning chemistry PDFs into a searchable, local knowledge base. The prototype extracts chemical names, resolves them to structures and links the results to their sources #Cheminformatics #ChemPython (1/5)

Try to imagine chemistry without JJ Berzelius, who, after thousands of experiments, published the first precise list of atomic weights (1818). Yet Berzelius might have remained a mere physician had he never met Anders Ekeberg. Teachers can influence the course of history. 🧪 #chemsky #chemistry

Gemini 2.5 Pro's reasoning on domain-specific topics is amazing (and a bit scary, too). Tested it with today’s Chemdl #182 (reaction scheme). The logical steps to the correct answer were spot on. Wow. #AI #ChemSky #LLM
