Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

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 ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...
