Combining exceptional porous polymers with patterning techniques would enable the fabrication of a new generation of devices with superior molecular size-selective features.On page 2277, S. H. Han, P. Falcaro, and co-workers propose a microfabrication protocol based on X-ray lithography.Remarkably, the irradiation process enhances the perm-selective properties.With this protocol, it is possible to apply thermally rearranged polymer to deliver gas molecules, such as oxygen and carbon dioxide, within miniaturized devices. NanostructuresHierarchical ZnO nanostructures decorated with gold nanopariticles are fabricated by J.-H.Jang and co-workers.The nanostructures are used for solar-based water splitting.The results shown on page 2341 denote the possibility of enhancing light absorption properties via an effi cient photon-trapping effect.A combination of properly designed nanostructures and surface plasmon resonance improves the performance of photocatalytic hydrogen generation.
