For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a stream of tiny ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

One longstanding problem has sidelined life-saving drugs, stalled next-generation batteries, and kept archaeologists from identifying the origins of ancient artifacts. For more than 100 years, ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

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 ...

For many decades, the method to obtain atomic-level descriptions of chemical compounds and materials—be it a drug, a catalyst ...
