What is Atom Probe Tomography? Atom Probe Tomography (APT) is a powerful analytical technique that provides three-dimensional (3D) imaging and chemical composition analysis of materials at the atomic ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...

NMAH copy purchased with funds from the S. Dillon Ripley Endowment. This comprehensive scientific history presents for the first time a detailed and comprehensive study of the Bohr atom in all its ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...
