Catalysts facilitate crucial chemical reactions in nature and industry alike. In a subset of them, catalytic activity is triggered by light. For example, when iron pentacarbonyl—a molecule in which 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 ...

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 ...

Exploiting the hyperfine structure in repulsive light-assisted collisions (LAC) on a 87-Rubidium atom pair in an optical tweezer. When atoms collide, their exact structure—for example, the number of ...

In the second paper, taking a major step forward for clean energy and materials design, a research team led by N'gom and Fohtung captured, for the first time, real-time 3D images of structural atomic ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...
