説明

<jats:title>Composite membranes for filtering solvents</jats:title> <jats:p> Much research has focused on finding membranes that can purify water or extract waste carbon dioxide. However, there is also a need for the removal of small molecules from organic liquids. Many existing processes are energy-intensive and can require large quantities of solvents. Karan <jats:italic>et al.</jats:italic> grew confined polymer layers on a patterned sacrificial support to give rippled thin films that were then placed on ceramic membranes (see the Perspective by Freger). The composite membrane showed high flux for organic solvents and good stability and was able to separate out small molecules with high efficiency. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6241" page="1347" related-article-type="in-this-issue" vol="348" xlink:href="10.1126/science.aaa5058">1347</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6241" page="1317" related-article-type="in-this-issue" vol="348" xlink:href="10.1126/science.aab3727">1317</jats:related-article> </jats:p>
