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 ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...

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 ...

Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This is one of the earliest concave ...
