5. Breaking the nanometer barrier in X-ray microscopy
   11-09-2006 · EurekAlert!
   Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height. Combining x-ray reflection together with high resolution x-ray microscopy, scientists can now study interactions at the nanometer-scale which often can exhibit different properties. Improving our understanding of interactions at the nanoscale holds promise to help us cure the sick, protect our environment and make us more secure.
