The white membrane is wafer-thin, big as a beer mat and yet destined for something bigger. At least if the plan by researchers from Norway and the USA works out. Because the plastic film should help to enrich climate-damaging carbon dioxide from power plant and industrial exhaust gases inexpensively and particularly quickly. The greenhouse gas flows through the novel membrane at record speed, while other gases remain behind. reports the team in the journal Science. The CO₂ separated in this way can be tapped behind the membrane, pressed into underground storage facilities or used as a raw material in the chemical industry.
