Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

Electromagnetic scattering and diffraction analysis is a critical field that underpins our understanding of wave interactions with various obstacles and interfaces. This area of research encompasses ...

Single-crystal diffraction was invented 100 years ago by Max von Laue. It has since become a workhorse technique for chemists to determine the structures of organometallic complexes and other ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...
