Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — a positron — locked in orbit ...

In the field of scanning electron microscopy (SEM), the electron backscatter diffraction (EBSD) method has developed into a robust tool for the crystallographic analysis of materials. Specifically, ...

For decades, relaxor ferroelectrics have powered everything from medical ultrasounds to sonar systems, yet their inner atomic ...

For the first time, researchers directly characterized the 3D atomic structure of a relaxor ferroelectric, a class of ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

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 ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...
