Acronym in imaging technology: UEM for ultrafast electron microscopy

In nanoscience, UEM stands for ultrafast electron microscopy. This technology is applicable to studies in materials science, mineralogy, nanotechnology and biology by providing real-space images, diffraction patterns and energy spectra at the nanoscale. Short nanomovies, demonstrating the nanoscopic imaging capability of UEM, can be viewed online at ScientificAmerican.com/aug2010/nanomovies.
