Biocompatible MOFs for storage and separation of O2: A molecular simulation study
Gülçay, Ezgi; Fındıkçı, İlknur Eruçar (American Chemical Society, 2019-02-27)Metal organic frameworks (MOFs) are great candidates for capturing 02 due to their highly porous structures and tunable physical and chemical properties. In this study, we assessed the performance of 1525 biocompatible ... -
