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

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

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 ...

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

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 ...

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 ...
