Using genetic algorithms to systematically improve the synthesis conditions of Al-PMOF

Fatmah Ebrahim, Seyedmohamad Moosavi, Berend Smit, Christopher Patrick Ireland, Christoph Leopold Talirz, Kevin Maik Jablonka

The synthesis of metal-organic frameworks (MOFs) is often complex and the desired structure is not always obtained. In this work, we report a methodology that uses a joint machine learning and experimental approach to optimize the synthesis conditions of A ...
