Simple and efficient methods of organizing materials are key to the realiza
tion of a nanotech world. These authors report on recent developments in si
mple evaporation-induced self-assembly processes, which enable the rapid pr
oduction of patterned porous or nanocomposite materials. The Figure shows a
calcined particle exhibiting vesicular mesophase, which was generated by a
erosol self-assembly of the tri-block copolymer P123.
