Impure chemical mixtures can now be separated based on differences in molecular silhouette. Membranes have been developed with nanoscale pores that match the shape of impurities in the mix so that only the impurity can pass through. KAUST researchers have suggested that the first application of these metal-organic framework (MOF) based shape-selective membranes could be energy-efficient, low-cost purification of natural gas.
