Harnessing Molecular Crystals: A Breakthrough for Nuclear Waste Disposal

Researchers at the University of Houston have developed molecular crystals based on cyclotetrabenzil hydrazones that have the potential to capture radioactive iodine, a common fission product in nuclear waste. These crystals can capture iodine in aqueous and organic solutions, as well as on the interface between the two, preventing it from damaging nuclear reactor coatings and waste containment vessels. The crystals exhibit a high iodine uptake capacity and can be reused, offering a promising solution for the safe management of nuclear waste. The researchers are also exploring other applications for these crystals, such as capturing carbon dioxide and potential use in energy storage.
