Fabricating Ordered Voids in a Colloidal Crystal FilmΒ±Substrate System by Using Organic Liquid Patterns as Templates A very clean route to porous materials, utilizing the combination of conventional solution and supercritical fluid processing, is exploited to prepare porous tissue engineering scaffolds that contain biologically active material for controlled release. This allows accurate dosing of the biological agent, whilst retaining the advantages of supercritical fluid technology. The retention of biological activity throughout the processing is also demonstrated. A wide range of alternative morphologies, including microparticles, are possible simply via control of the method of depressurization.

Nanocomposite glasses containing metallic nanoparticles can be microstructured by electric-field assisted dissolution of the embedded particles. As reported by Graener and co-workers on p. 2983, any pattern of the electrode-down to the nanoscale-can be transferred onto the nanocomposite glass, givin
Advanced Materials' crystal anniversary (i.e., 15 years of publication) will take place next year. As explained in this Editorial, we have taken the liberty of celebrating a little in advance with a special section containing some highlights from Advanced Materials' past, e.g.
