For the first time researchers at ORNL have used an electron microscope to image the formation of lithium dendrites in a miniature electrochemical cell that simulates the conditions in a lithium-ion battery.

This cryo-electron tomography image reveals the internal structure of an ultra-small bacteria cell like never before. The cell has a very dense interior compartment and a complex cell wall. The darker spots at each end of the cell are most likely ribosomes. The image was obtained from a 3-D reconstruction. The scale bar is 100 nanometers. (Credit: Berkeley La

Hitachi Develops 43 picometers Resolution Holography Electron Microscope

View News 2/19/2015

Developed by Hitachi the atomic-resolution holography electron microscope can measure electromagnetic fields at the resolution of 43 picometer. The determination of atomic structure and characterization of the electromagnetic properties of materials is used to understand the properties of the materials.

The image on the left shows distortion of lanthanum and strontium directly resolved at the the atomic scale. Blue and red colors indicate contraction and expansion of the local structure respectively. The image on the right shows that the aluminum and tantalum sites exhibit dramatically different distortion behavior due to bonding. Image credit: James LeBeau

Cornell University has received a NSF grant cryogenic, aberration-corrected scanning transmission electron microscope that will be used for imaging of inorganic materials at subatomic resolution while cooled.

Low-energy electron microscopy images of the nickel-aluminum surface before and after oxidation. The faint lines before oxidation indicate the atom-high steps that separate flat terrace sections of the crystal surface. As oxidation begins at a point on one terrace, the oxide spreads in elongated stripes along that terrace, pushing steps out of the way and bunching them closer and closer together. Eventually the bunching of steps stops the growth of the oxide stripe and another begins to form, often at right angles, to produce a grid-like pattern.

LEEM Reveals How Atom-High Steps Impede Oxidation of Metal Surfaces

This FIB Doesn’t Lie: New NIST Microscope Sees What Others Can’t

View News 5/6/2014

Scientists at the National Institute of Standards and Technology (NIST) recently built the world's first low-energy focused ion beam (FIB) microscope that uses a lithium ion source, opening the door to a new category of FIBs that can use any one of 20 different elements. The new FIB can image nonconductive materials and chemical composition of surface samples more clearly than higher-energy SEMs and FIBs. It could provide solutions for common problems in nanoimprint lithography by helping users clear chemical residue from silicon chips in order to etch into the silicon.
