  • Electrifying Neutrons: Monochromated electron energy loss spectroscopy in the scanning transmission electron microscope is used to distinguish between molecules that differ only by a single neutron on a single atom. The electron beam can capture changes to the minute molecular vibrations of an amino acid caused by the extra neutron without damaging the sample and with unprecedented spatial resolution.

  • Oak Ridge National Laboratory scientists used a monochromated, aberration-corrected scanning transmission electron microscope, or MAC-STEM, technique that detects the subtle changes in the weight of proteins at the nanoscale—while keeping the sample intact— is the perfect complement to a macroscale mass spectrometry experiment.
