U.S. Army Scientists Think Big by Going Small.

ABERDEEN PROVING GROUND, Md. (Aug. 21, 2018) -- When material scientists from the U.S. Army Research Laboratory think big, they start by exploring the world of the really small.

Using state-of-the-art technology and tools, Army scientists are analyzing metal and ceramic specimens at the atomic level.

To get an idea of the size they're working with, imagine the width of a hair. The samples are a thousand times smaller than the end of a strand of human hair.

The atom probe, researchers said, has become a key to understanding the structure of materials.

           "It's basically the only machine in the world that can do this at the atomic level"

"The atom probe gives us a 3-D reconstruction at the atomic level," said Dr. Chad Hornbuckle, a materials scientist with the laboratory's Weapons and Materials Research Directorate. "When you see the reconstruction that's made up of millions of dots, the dots are actually individual atoms."
