Alexander Rack (Runner-up for the Jan/Feb issue)
European Synchrotron Radiation Facility, France. Bioceramic-supported bone regeneration can be studied in three dimensions using high resolution computed tomography (CT) in combination with hard X-ray synchrotron radiation. The data set shown as volume rendering was taken ex vivo 12 weeks after the implementation of the particles in a sheep mandible. Newly formed bone (red) can be seen which forms around the decomposing ceramic (gray)

July
Jan Linnros and Benjamin Bruhn
Royal Institute of Technology, Sweden. Nano-flower: the star-shaped structure was prepared by e-beam lithography and plasma etching of an ordinary silicon wafer.

August
Amanda Barnard (Runner-up for the Jul/Aug issue)
Virtual Nanoscience Laboratory
CSIRO Materials Science & Engineering, Australia. Blue glass fullerene models embedded in ice cubes at different stages of melting. It is designed to invoke the concept of nanomaterials interacting with realistic conditions such as finite and different chemical environments (such as air and water). It is 300 dpi (minimum dimensions 150 mm).
