Creating New Types of Carbon-Based Membranes

Science | Carbon-based membranes (1) for gas separations, which can be produced by pyrolysis of various precursor polymers, have had limited commercial use to date, in part because of their high cost and fragile mechanical nature. In this issue, unusual permeation behavior is reported for membranes made from two quite different forms of carbon that make them attractive for molecular separations or perhaps other uses.
