Thinking small is not easy - pp121 - 122

Carl A. Batt

doi:10.1038/nnano.2008.52

The enormous difference in scale between our everyday world and the nanoworld could explain why so few members of the general public seem to know about nanotechnology.

Nanocrystals: Shedding new light on silicon - pp134 - 135

Ulrich Gösele

doi:10.1038/nnano.2008.40

Experiments in magnetic fields suggest that defects are responsible for light emission from silicon nanocrystals. However, when these defects are passivated with hydrogen, quantum effects become responsible for the emission.

Nanobiotechnology: Putting cobalt on the menu - pp135 - 136

Michael Winklhofer

doi:10.1038/nnano.2008.45

Nanocrystals of magnetite in magnetic bacteria are known for their high chemical purity, but recent work shows they can be doped with cobalt. This finding could pave the way for the biosynthesis of magnetically tailored nanoparticles.
