We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but here we are with [Twisted & Tinned], who’s made a novel clock with a ...

Abstract: A novel reflection-reduced two-layer grating is described with nearly 100% diffraction efficiency. The efficiency of the conventional grating should be improved, or some reported ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

Abstract: The paper considers the issue of increasing the efficiency of using higher diffraction orders of an amplitude transmitting diffraction grating for the purposes of spectral analysis of ...

I learned in October 2022’s Breakthrough that the spikes of stars in high-power photos are called diffraction spikes. Why do they appear as two crosses at 45 degrees to each other? The diffraction ...

When separating various wavelengths of light with high spectral resolution in a compact, efficient manner, diffraction grating is the answer to your specific requirements. Diffraction gratings are ...
