Microscopy
Advancement in energy, environment and biology research relies heavily on micro-, nano- and atomic-scale chemical and structural imaging. Many microscopy instruments have high-resolution imaging capabilities including complementary chemical, structural and phase information, in-situ imaging in native environments and imaging of dynamic processes with high temporal-resolution. See a complete list of Microscopy instruments.
Resources and Techniques
- Nanoscale and sub-nanoscale imaging allows users to elucidate chemical processes and acquire structural data for a variety of samples such as nanostructures and cell-surface proteins.
- Tomography yields three-dimensional reconstruction of transmission electron microscopy images generated for biological samples as well as for soft materials and samples with 3D structural heterogeneity.
- Environmental particle analysis offers knowledge about non-volatile atmospheric particle composition and hydration properties using high-pressure scanning electron microscopy equipped with energy-dispersive x-ray analysis capability.
- Environmental mode imaging techniques enable sample preservation to eliminate extensive preparation procedures that can introduce artifacts and make possible live-cell imaging and in situ imaging in liquids or controlled gas environments with high resolution microscopy.
- Dynamic imaging capability enables real-time studies of nanosecond-scale dynamic processes with unprecedented spatial resolution, such as protein-protein interactions, with contrast at the single-molecule level.
Quiet Wing for Advanced Microscopy
Seven microscopes are housed in the Quiet Wing, a space specially designed to reduce external factors, such as vibrations and electromagnetic fields, that can impede capture of high-resolution images. Read more about the Quiet Wing and its instrumentation.
A new DTEM – Dynamic Transmission Electron Microscope – is under development at EMSL in collaboration with scientific colleagues at Pacific Northwest National Laboratory. It will be housed in the Quiet Wing. To learn more about this system, the science it will advance and its historical development, visit the DTEM page.
