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

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

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

Fundamentals of electron diffraction -- Relation between crystal lattice, stereographic projection and reciprocal lattice -- Indexing polycrystalline and single-crystal patterns -- Orientation ...

2D-XRD, or two-dimensional X-ray diffraction, is a powerful analytical technique used to study the atomic and molecular structure of crystalline materials at the nanoscale. It provides detailed ...

(Nanowerk News) Turning up the intensity of x-ray beams used to probe the atomic structures of materials can actually reduce the intensity of x-rays scattered from the material, a RIKEN-led team has ...

THE electron diffraction patterns of thin films of alloys sometimes show fine detail that is not fully understood 1. Empirical methods of solution are not easy to apply in view of the large number of ...

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 ...
