Team Develops Electron Microscope with 0.5-Å Resolution
Although studying how atoms come together to form matter is a central goal of science, it is difficult to study the particles because they measure only about 1 Å. For reference, 500,000 to one million angstroms comprise the width of an average strand of human hair, and the diameter of a DNA helix measures approximately 20 Å.
An electron microscope now has achieved 0.5-Å resolution. It was developed by several national laboratories of the US Department of Energy, by FEI Company in Hillsboro,...
