Scientists have finally glimpsed chemistry at its smallest level after capturing the first-ever X-ray of a single atom. Atoms are the tiniest particles in our universe, and they're the basic ...
In a basement room at Austria's University of Graz sits a jumble of steel tanks and ice-encrusted tubes. The contraption, a scanning tunneling microscope, can snap pictures of individual atoms and ...
When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a ...
