Nanofabrication Yields Sharper Focus For Soft X-Rays|
Progress in nanoscience and nanotechnology depends not only on examining the surfaces of things but on seeing deep inside biological organisms and material structures to identify what they're made of — and what electronic, magnetic, optical, and chemical processes may be in play.

A New Model of Quantum Dots: Rethinking the Electronics|
Quantum dots, tiny crystals consisting of a few hundred to a few thousand atoms, sparkle with promise for uses ranging from tagging proteins in living cells to foiling counterfeiters to enabling quantum computers. The optics and electronics of these semiconductor nanocrystals are dramatically different from the same materials in bulk. But it turns out that one of the most important electronic properties of quantum dots has been misunderstood for over a decade.
