In 1912, scientists invented X-ray crystallography and revealed a crystal’s atomic structure for the first time Tess Joosse Humans have marveled at crystals for millennia. Viridescent emerald, rich ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

RECENTLY we have obtained transmission patterns from graphite powders in which prominent extra rings appear ; owing to insufficient resolution these have hitherto escaped notice. Two of these rings ...
