Credit: ChemRxiv DOI: 10.26434/chemrxiv-2025-3m7vv-v2 Scientists have adapted a centuries-old principle of chemistry to fine-tune a new type of glass made from metal–organic frameworks (MOFs)—metal atoms connected by organic molecules—that efficiently trap gases like CO₂ and hydrogen and even capture water. Publishing their findings in Nature Chemistry, an international research team, including scientists from TU Dortmund and the University of Birmingham, reveals that MOF glasses can be tuned and engineered in the same way as traditional glasses. Researchers discovered that adding small chemical compounds containing sodium or lithium to the glass changes its behavior and structure. The chemicals lower the temperature at which the glass softens and change how easily it flows when heated, which makes manufacturing easier.…
