Electron Microscopy
Electron Imaging Center for Nanomachines
What is Electron Microscopy?
Electron microscopy is a powerful extension of optical techniques into the sub-optical wavelength sized world. Using electrons accelerated to relativistic speeds, these microscopes can image individual atoms. Transmission electron microscopy requires a thin sample, about a micron or less, and thinner is better. It uses a variety of techniques to image and characterize samples. For example:
- High resolution imaging can resolve individual atoms.
- Cryo-EM can reveal structures and molecular interactions of biological complexes.
- STEM imaging can differentiate atom types.
- X-ray spectroscopy (EDX) can quantify elemental composition.
- Tomography can resolve the 3D structure of materials and biological complexes.

August 2, 2023 | True shape of lithium revealed for the first time in UCLA research
A study by members of the California NanoSystems Institute at UCLA reveals a fundamental discovery that could lead to safer lithium-metal batteries that outperform today’s lithium-ion batteries. The research was published today in the journal Nature.
Metallic lithium reacts so easily with chemicals that, under normal conditions, corrosion forms almost immediately while the metal is being laid down on a surface such as an electrode.
