(a) Schematic diagram of the angstrom-beam electron diffraction method. (b) Electron diffraction patterns obtained from amorphous Zr-Ni alloy with different beam sizes. The pattern with 100-nm beam ...

However, X-ray measurement of the elastic strain in amorphous materials — 'strain scanning' — has not been reported, because the diffraction signal from amorphous materials has been considered ...

In a recent study, researchers have developed a compound metalens that enables distortion-free imaging. The study, published ...
