Thumbnail image of graphical abstract

The cover picture shows aerogels, in which different layers are loaded with different metal nanoparticles (Au: red; Ag: orange; Pd: gray). The particles are functionalized with hydroxy-terminated alkane thiols and disperse well in sol–gel mixtures to give alcogels and, after supercritical drying, aerogels containing up to 90 wt% of nanoparticles. Layered or patterned nanoparticle–aerogel monoliths can be prepared by sequential casting or molding of the nanoparticle-containg sol–gels, and can find uses in directing multistep catalytic reactions. For more information, please read the Communication “Nanoparticle-Loaded Aerogels and Layered Aerogels Cast from Sol–Gel Mixtures” by B. A. Grzybowski and co-workers, beginning on page 2568.
