DESIGNER MATERIAL FOR CARBON CAPTURE

WORTH A THOUSAND WORDS Having a paper accepted for publication in a top journal demonstrates the significance of the work; having a paper featured on the cover of a journal pushes that significance to a higher level. A cover is, as they say, the icing on the cake. Ryan Luebke and Mohammed Eddaoudi had their cake iced in February when their paper (see illustration to right) was featured on the cover of ChemComm, a
