In a paper published this week in the journal Nature Materials, researchers from the Georgia Institute of Technology identified the opportunities they see ahead for scalable membrane materials based on rigid, engineered pore structures. They say the most promising materials are scalable for use in compact modules, and take advantage of entropy at the molecular level to moderate the separation selectivity of membranes. 鈥淚t鈥檚 all about energy and carbon dioxide,鈥?said William Koros, profes
