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

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

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 ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

X-ray diffraction (XRD) is a non-invasive method for determining that can be used in phase analysis investigations of crystalline materials. Image Credit: AgriTech/Shutterstock.com The essential idea ...
