Cover Picture: Avenues into Complex Materials: Cooperative Projects of the Natural, Engineering, and Biosciences (Small 6/2007)

The cover picture is a jigsaw‐puzzle‐styled collage of artwork that originates from microscopic pictures of nano‐, micro‐, and mesocalar structured objects, many of which have been studied under the auspices of the VolkswagenStiftung research program “Complex Materials”. This special issue of Small presents a variety of articles from international research collaborations funded by this program, which highlights the need for such collaboration to further advances in this exciting field of technology.
