A team led by the Department of Energy’s Oak Ridge National Laboratory has discovered a way to increase significantly the selectivity and binding strength of crown ethers by embedding them within a rigid framework of graphene. The results, published in Nature Communications , may enable broader use of crown ethers in diverse applications. Their strong, specific electrostatic binding may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy productio...
