A new X-ray microscope at Brookhaven National Laboratory is being used to create unparalleled high-resolution 3D images of the inner structure of materials. Using techniques similar to taking a very small-scale medical CAT (computer-assisted tomography) scan, the full field transmission x-ray microscope (TXM) enables scientists to directly observe structures spanning 25 nanometers - three thousand times smaller than a red blood cell - by splicing together thousands of images into a single 3D X-ray image with "greater speed and precision than ever before." This capability is expected to power rapid advances in many fields, including energy research, environmental sciences, biology, and national defense.
