Mendeleev is the shared work of two people. Arvin and Hossein started this project together and built it together; from the idea and design to the backend and security, both of them share an equal part.
Hossein is one of Mendeleev's two makers. He built the server architecture, the database and the site's security layer, and worked alongside Arvin on the design, content and user experience. The project is the shared work of the two of them, and every decision was made together.

Mendeleev is free and has no ads. We pay for hosting and the domain, the AI service and the verification-code SMS ourselves. If Mendeleev has helped you, any amount you choose can help keep it running, improve the data and build new features. Donating is optional and the site's features stay free without it.
