Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

M. G. FOUSSERAU describes, in the Journal de Physique for October, a simple apparatus for viewing diffraction and interference phenomena, a modified form of which I have experimented on with success.

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 ...
