Contains more than 21,000 diagrams for non-organic systems, including those published in all 21 hard-copy volumes produced as part of the ACerS-NIST Phase Equilibria Diagrams Program (formerly titled Phase Diagrams for Ceramists). The database additionally contains over 1,200 new phase diagrams labeled as “Volume 15” that are only available in electronic format.
An open chemistry database that collects information on chemical structures, identifiers, chemical and physical properties, biological activities, patents, health, safety, toxicity data, and many others. PubChem mostly contains small molecules, but also larger molecules. Examples include chemical compounds including drugs, nucleotides including siRNAs and miRNAs, carbohydrates, lipids, peptides and chemically-modified macromolecules.
