摘要
Getting their feet wet: Low-cost hydrocarbon surfactants act as fluid modifiers for supercritical carbon dioxide (scCO2). Increased terminal branching of the surfactant chains aids micelle formation (see middle picture:CO2 green), and more chains allows water to be incorporated (right, blue). © 2009 Wiley-VCH Verlag GmbH & Co.
