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 ...

X-ray diffraction methods lie at the foundation of materials science. Determination of the crystal structures of natural minerals and, later, of crystals grown in the laboratory led to our ...

Scientists from the University of Manchester have shown how a plasma-based approach, using nonthermal plasma—an electrically energized gas often described as the fourth state of matter—can prevent ...

Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 ...

IF a fine beam of homogeneous cathode rays is sent nearly normally through a thin celluloid film (of the order 3 × 10 6 cm. thick) and then received on a photographic plate 10 cm. away and parallel to ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.
